Comprehensive analysis of Dendrobium catenatum HSP20 family genes and functional characterization of DcHSP20-12 in response to temperature stress. Int J Biol Macromol 2024; 258:129001. [PMID: 38158058 DOI: 10.1016/j.ijbiomac.2023.129001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 12/19/2023] [Accepted: 12/21/2023] [Indexed: 01/03/2024]
Abstract
Heat shock proteins (HSPs) are a class of protective proteins in response to abiotic stress in plants, and HSP20 plays an essential role in response to temperature stress. However, there are few studies on HSP20 in Dendrobium catenatum. In this study, 18 DcHSP20 genes were identified from the D. catenatum genome. Phylogenetic analysis showed that DcHSP20s could be classified into six subgroups, each member of which has similar conserved motifs and gene structures. Gene expression analysis of 18 DcHSP20 genes revealed that they exhibited variable expression patterns in different plant tissues. Meanwhile, all 18 DcHSP20 genes were induced to be up-regulated under high temperature, while six genes (DcHSP20-2/9/10/12/16/17) were significantly up-regulated under low temperature. Moreover, combining gene expression under high and low temperature stress, the DcHSP20-12 gene was cloned for functional analysis. The germination ratios, fresh weights, root lengths of two DcHSP20-12-overexpressing transgenic Arabidopsis thaliana lines were significantly higher, but MDA contents were lower than that of wild-type (WT) plants under heat and cold stresses, displayed enhanced thermotolerance and cold-resistance. These results lay a foundation for the functional characterization of DcHSP20s and provide a candidate gene, DcHSP20-12, for improving the tolerance of D. catenatum to temperature stress in the future.

General Analysis of Heat Shock Factors in the Cymbidium ensifolium Genome Provided Insights into Their Evolution and Special Roles with Response to Temperature. Int J Mol Sci 2024; 25:1002. [PMID: 38256078 PMCID: PMC10815800 DOI: 10.3390/ijms25021002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 12/27/2023] [Accepted: 01/08/2024] [Indexed: 01/24/2024] Open
Abstract
Heat shock factors (HSFs) are the key regulators of heat stress responses and play pivotal roles in tissue development and the temperature-induced regulation of secondary metabolites. In order to elucidate the roles of HSFs in Cymbidium ensifolium, we conducted a genome-wide identification of CeHSF genes and predicted their functions based on their structural features and splicing patterns. Our results revealed 22 HSF family members, with each gene containing more than one intron. According to phylogenetic analysis, 59.1% of HSFs were grouped into the A subfamily, while subfamily HSFC contained only two HSFs. And the HSF gene families were differentiated evolutionarily between plant species. Two tandem repeats were found on Chr02, and two segmental duplication pairs were observed on Chr12, Chr17, and Chr19; this provided evidence for whole-genome duplication (WGD) events in C. ensifolium. The core region of the promoter in most CeHSF genes contained cis-acting elements such as AP2/ERF and bHLH, which were associated with plant growth, development, and stress responses. Except for CeHSF11, 14, and 19, each of the remaining CeHSFs contained at least one miRNA binding site. This included binding sites for miR156, miR393, and miR319, which were responsive to temperature and other stresses. The HSF gene family exhibited significant tissue specificity in both vegetative and floral organs of C. ensifolium. CeHSF13 and CeHSF15 showed relatively significant expression in flowers compared to other genes. During flower development, CeHSF15 exhibited markedly elevated expression in the early stages of flower opening, implicating critical regulatory functions in organ development and floral scent-related regulations. During the poikilothermic treatment, CeHSF14 was upregulated over 200-fold after 6 h of heat treatment. CeHSF13 and CeHSF14 showed the highest expression at 6 h of low temperature, while the expression of CeHSF15 and CeHSF21 continuously decreased at a low temperature. The expression patterns of CeHSFs further confirmed their role in responding to temperature stress. Our study may help reveal the important roles of HSFs in plant development and metabolic regulation and show insight for the further molecular design breeding of C. ensifolium.

Abstract
Heat shock transcription factors (HSFs) play a crucial role in regulating plant growth and response to various abiotic stresses. In this study, we conducted a comprehensive analysis of the AeHSF gene family at genome-wide level in kiwifruit (Actinidia eriantha), focusing on their functions in the response to abiotic stresses. A total of 41 AeHSF genes were identified and categorized into three primary groups, namely, HSFA, HSFB, and HSFC. Further transcriptome analysis revealed that the expression of AeHSFA2b/2c and AeHSFB1c/1d/2c/3b was strongly induced by salt, which was confirmed by qRT-PCR assays. The overexpression of AeHSFA2b in Arabidopsis significantly improved the tolerance to salt stress by increasing AtRS5, AtGolS1 and AtGolS2 expression. Furthermore, yeast one-hybrid, dual-luciferase, and electrophoretic mobility shift assays demonstrated that AeHSFA2b could bind to the AeRFS4 promoter directly. Therefore, we speculated that AeHSFA2b may activate AeRFS4 expression by directly binding its promoter to enhance the kiwifruit's tolerance to salt stress. These results will provide a new insight into the evolutionary and functional mechanisms of AeHSF genes in kiwifruit.

Abstract
High-temperature stress is the main environmental stress that restricts the growth and development of woody plants, and the growth and development of woody plants are affected by high-temperature stress. The influence of high temperature on woody plants varies with the degree and duration of the high temperature and the species of woody plants. Woody plants have the mechanism of adapting to high temperature, and the mechanism for activating tolerance in woody plants mainly counteracts the biochemical and physiological changes induced by stress by regulating osmotic adjustment substances, antioxidant enzyme activities and transcription control factors. Under high-temperature stress, woody plants ability to perceive high-temperature stimuli and initiate the appropriate physiological, biochemical and genomic changes is the key to determining the survival of woody plants. The gene expression induced by high-temperature stress also greatly improves tolerance. Changes in the morphological structure, physiology, biochemistry and genomics of woody plants are usually used as indicators of high-temperature tolerance. In this paper, the effects of high-temperature stress on seed germination, plant morphology and anatomical structure characteristics, physiological and biochemical indicators, genomics and other aspects of woody plants are reviewed, which provides a reference for the study of the heat-tolerance mechanism of woody plants.

PLANTS (BASEL, SWITZERLAND) 2022; 11:2763.

Abstract
Alfalfa (Medicago sativa) is one of the most important legume forage species in the world. It is often affected by several abiotic stressors that result in reduced yields and poor growth. Therefore, it is crucial to study the resistance of M. sativa to abiotic stresses. Heat shock transcription factors (HSF) are key players in a number of transcriptional regulatory pathways. These pathways play an essential role in controlling how plants react to different abiotic stressors. Studies on the HSF gene family have been reported in many species but have not yet undergone a thorough analysis in M. sativa. Therefore, in order to identify a more comprehensive set of HSF genes, from the genomic data, we identified 16 members of the MsHSF gene, which were unevenly distributed over six chromosomes. We also looked at their gene architectures and protein motifs, and phylogenetic analysis allowed us to divide them into 3 groups with a total of 15 subgroups. Along with these aspects, we then examined the physicochemical properties, subcellular localization, synteny analysis, GO annotation and enrichment, and protein interaction networks of amino acids. Finally, the analysis of 16 MsHSF genes' expression levels across all tissues and under four abiotic stresses using publicly available RNA-Seq data revealed that these genes had significant tissue-specific expression. Moreover, the expression of most MsHSF genes increased dramatically under abiotic stress, further validating the critical function played by the MsHSF gene family in abiotic stress. These results provided basic information about MsHSF gene family and laid a foundation for further study on the biological role of MsHSF gene in response to stress in M. sativa.

Abstract
33 heat shock protein 20 (Hsp20) genes were identified from the carnation genome whose expression were altered by abiotic stresses. DcHsp17.8 may function to improve the heat resistance of Arabidopsis. Heat shock proteins 20 (Hsp20s) mainly function as molecular chaperones that play crucial roles in relieving abiotic stresses such as heat stress. In this study, we identified and characterized 33 DcHsp20 genes from the carnation genome that were classified into 9 subfamilies. Gene structure analysis showed that 25 DcHsp20 genes contained 1 intron whilst the remaining 8 DcHsp20 genes did not contain introns. Motif analysis found that DcHsp20 proteins were relatively conserved. Cis-regulatory elements analysis of the Hsp20 promoters revealed a number of cis-regulatory elements that regulate growth and development, hormone and stress responses. Gene expression analysis revealed that DcHsp20 genes had multiple response patterns to heat stress. The largest range of induction occurred in DcHsp17.8 after 1 h of heat stress. Under cold stress, or treatment with saline or abscisic acid, the expression of most DcHsp20 genes was inhibited. To further understand the function of DcHsp20 genes in response to heat stress, we overexpressed DcHsp17.8 in Arabidopis and the plants showed improved heat tolerance, O2- and H2O2 activities and photosynthetic capacity with reduced relative electrolyte leakage and malondialdehyde content. Gene expression analysis revealed that DcHsp17.8 modulated the expression of genes involved in antioxidant enzyme synthesis. Our data provided a solid foundation for the further detailed study of DcHsp20 genes.

PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2022; 175:68-80.

Abstract
Heat shock transcription factors (Hsfs) are essential regulators of plant responses to abiotic stresses, growth, and development. However, all the Hsf family members have not been identified in Sorbus pohuashanensis. Therefore, the aim of this study was to identify the Hsf family members in S. pohuashanensis and examine their expression under abiotic stress conditions through the integration of gene structure, phylogenetic relationships, chromosome location, and expression patterns. Bioinformatics-based methods, identified 33 Hsfs in S. pohuashanensis. Phylogenetic analysis of Hsfs from S. pohuashanensis and other species revealed that they were more closely related to apples and white pears, followed by Populus trichocarpa, and most distantly related to Arabidopsis. Moreover, the Hsfs were clustered into three major groups: A, B, and C. Gene structure and conserved motif analysis revealed a high degree of conservation among members of the same class. Collinearity analysis revealed that segmental duplication played an essential role in increasing the size of the SpHsfs gene family in S. pohuashanensis. Additionally, several cis-acting elements associated with growth and development, hormone response, and stress were found in the promoter region of SpHsfs genes. Furthermore, expression analysis in various tissues of S. pohuashanensis showed that the genes were closely associated with heat, drought, salt stress, growth, and developmental processes. Overall, these results provide valuable information on the evolutionary relationships of the Hsf gene family. These genes stand as strong functional candidates for further studies on the resistance of S. pohuashanensis to abiotic stresses.

Large-scale analyses of heat shock transcription factors and database construction based on whole-genome genes in horticultural and representative plants. HORTICULTURE RESEARCH 2022; 9:uhac035. [PMID: 35184193 PMCID: PMC9123238 DOI: 10.1093/hr/uhac035] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 12/18/2021] [Accepted: 01/11/2022] [Indexed: 06/14/2023]
Abstract
Heat shock transcription factor (Hsf) plays a critical role in regulating heat resistance. Here, 2950 Hsf family genes were identified from 111 horticultural and representative plants. More Hsf genes were detected in higher plants than lower plants. Based on all Hsf genes, we constructed a phylogenetic tree, which indicated that Hsf genes of each branch evolved independently after species differentiation. Furthermore, we uncovered the evolutionary trajectories of Hsf genes by motif analysis. There were only 6 motifs (M1 to M6) in lower plants, and then 4 novel motifs (M7-M10) appeared in higher plants. However, the motifs of some Hsf genes were lost in higher plant, indicating that Hsf genes have undergone sequence variation during the evolution. The number of Hsf gene loss was more than duplication after whole-genome duplication in higher plants. The heat response network was constructed using 24 Hsf genes, 2421 downstream, and 222 upstream genes of Arabidopsis. Further enrichment analysis revealed that Hsf genes and other transcription factors interacted with each other to response heat resistance. The global expression maps were illustrated for Hsf genes under various abiotic, biotic stresses, and several developmental stages in Arabidopsis. The syntenic and phylogenetic analyses were conducted using Hsf genes of Arabidopsis and Pan-genome of 18 Brassica rapa accessions. We also performed the expression pattern analysis of Hsf and six Hsp family genes using expression values from different tissues and heat treatments in B. rapa. The interaction network between Hsf and Hsp gene families was constructed in B. rapa, and several core genes were detected in the network. Finally, we constructed a Hsf database (http://hsfdb.bio2db.com) for researchers to retrieve Hsf gene family information. Therefore, our study will provide rich resources for the evolution and functional study of Hsf genes.

Abstract
Background The heat shock factor (Hsf) and small heat shock protein (sHsp, also called Hsp20) complex has been identified as a primary component in the protection of plant cells from ubiquitous stresses, particularly heat stress. Our study aimed to characterize and analyze the Hsf and Hsp genes in Brachypodium distachyon, an annual temperate grass and model plant in cereal and grass studies. Results We identified 24 Hsf and 18 Hsp20 genes in B. distachyon and explored their evolution in gene organization, sequence features, chromosomal localization, and gene duplication. Our phylogenetic analysis showed that BdHsfs could be divided into three categories and BdHsp20s into ten subfamilies. Further analysis showed that the 3’UTR length of BdHsp20 genes had a negative relationship with their expression under heat stress. Expression analyses indicated that BdHsp20s and BdHsfs were strongly and rapidly induced by high-temperature treatment. Additionally, we constructed a complex regulatory network based on their expression patterns under heat stress. Morphological analysis suggested that the overexpression of five BdHsp20 genes enhanced the seed germination rate and decreased cell death under high temperatures. Conclusion Ultimately, our study provided important evolutionary and functional characterizations for future research on the regulatory mechanisms of BdHsp20s and BdHsfs in herbaceous plants under environmental stress.

Genome-Wide Comparative Analysis of Heat Shock Transcription Factors Provides Novel Insights for Evolutionary History and Expression Characterization in Cotton Diploid and Tetraploid Genomes. Front Genet 2021; 12:658847. [PMID: 34168673 PMCID: PMC8217870 DOI: 10.3389/fgene.2021.658847] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 03/15/2021] [Indexed: 11/13/2022] Open
Abstract
Heat shock transcription factors (HSFs) are involved in environmental stress response and plant development, such as heat stress and flowering development. According to the structural characteristics of the HSF gene family, HSF genes were classified into three major types (HSFA, HSFB, and HSFC) in plants. Using conserved domains of HSF genes, we identified 621 HSF genes among 13 cotton genomes, consisting of eight diploid and five tetraploid genomes. Phylogenetic analysis indicated that HSF genes among 13 cotton genomes were grouped into two different clusters: one cluster contained all HSF genes of HSFA and HSFC, and the other cluster contained all HSF genes of HSFB. Comparative analysis of HSF genes in Arabidopsis thaliana, Gossypium herbaceum (A1), Gossypium arboreum (A2), Gossypium raimondii (D5), and Gossypium hirsutum (AD1) genomes demonstrated that four HSF genes were inherited from a common ancestor, A0, of all existing cotton A genomes. Members of the HSF gene family in G. herbaceum (A1) genome indicated a significant loss compared with those in G. arboretum (A2) and G. hirsutum (AD1) A genomes. However, HSF genes in G. raimondii (D5) showed relative loss compared with those in G. hirsutum (AD1) D genome. Analysis of tandem duplication (TD) events of HSF genes revealed that protein-coding genes among different cotton genomes have experienced TD events, but only the two-gene tandem array was detected in Gossypium thurberi (D1) genome. The expression analysis of HSF genes in G. hirsutum (AD1) and Gossypium barbadense (AD2) genomes indicated that the expressed HSF genes were divided into two different groups, respectively, and the expressed HSF orthologous genes between the two genomes showed totally different expression patterns despite the implementation of the same abiotic stresses. This work will provide novel insights for the study of evolutionary history and expression characterization of HSF genes in different cotton genomes and a widespread application model for the study of HSF gene families in plants.

Abstract
Plant heat shock transcription factors (Hsfs) play a significant role in adoption under abiotic stress conditions by modulating the expression of several stress-responsive genes. Analysis of the Hsf gene family will serve to understand the molecular mechanism which is involved in response to abiotic stress. The Ziziphus species grows in warm and dry regions and is inherently tolerant to abiotic stress conditions; thus, Ziziphus is a highly enriched source of genes conferring abiotic stress tolerance. Therefore, the present study provides a comprehensive genome-wide analysis of the Hsf gene family in Z. jujuba. Identified 21 non-redundant Hsf genes were grouped into three major classes (classes A, B, and C) based on the phylogenetic analysis. Promoter and gene ontology analysis suggested that ZjHsfs perform diverse functions in response to abiotic stress conditions. Two paralogous pairs resulting from tandem gene duplication events were identified. Also, physio-chemical properties of chromosomal locations, gene structure, motifs, and protein domain organization of Hsfs were analyzed. Real-time PCR expression analyses revealed that most of the Z. jujuba Hsf genes are differentially expressed in response to heat stress. The analysis suggested ZjHsf-2, ZjHsf-3, ZjHsf-5, ZjHsf-7, ZjHsf-8, ZjHsf-10, ZjHsf-12, ZjHsf-17, and ZjHsf-18 were the outstanding candidate genes for imparting heat stress tolerance and for future functional analysis. The present analysis laid the foundation for understanding the molecular mechanism of the Hsf gene family regulating Z. jujuba development and tolerance to abiotic stress conditions.

Abstract
Small heat shock proteins (sHSPs) are an ubiquitous protein family found in archaea, bacteria and eukaryotes. In plants, as in other organisms, sHSPs are upregulated by stress and are proposed to act as molecular chaperones to protect other proteins from stress-induced damage. sHSPs share an 'α-crystallin domain' with a β-sandwich structure and a diverse N-terminal domain. Although sHSPs are 12-25 kDa polypeptides, most assemble into oligomers with ≥ 12 subunits. Plant sHSPs are particularly diverse and numerous; some species have as many as 40 sHSPs. In angiosperms this diversity comprises ≥ 11 sHSP classes encoding proteins targeted to the cytosol, nucleus, endoplasmic reticulum, chloroplasts, mitochondria and peroxisomes. The sHSPs underwent a lineage-specific gene expansion, diversifying early in land plant evolution, potentially in response to stress in the terrestrial environment, and expanded again in seed plants and again in angiosperms. Understanding the structure and evolution of plant sHSPs has progressed, and a model for their chaperone activity has been proposed. However, how the chaperone model applies to diverse sHSPs and what processes sHSPs protect are far from understood. As more plant genomes and transcriptomes become available, it will be possible to explore theories of the evolutionary pressures driving sHSP diversification.

Genome-Wide Identification and Characterization of Heat-Shock Transcription Factors in Rubber Tree. FORESTS 2019.

Abstract
Heat-shock transcription factors (Hsfs) play a pivotal role in the response of plants to various stresses. The present study aimed to characterize the Hsf genes in the rubber tree, a primary global source of natural rubber. In this study, 30 Hsf genes were identified in the rubber tree using genome-wide analysis. They possessed a structurally conserved DNA-binding domain and an oligomerization domain. On the basis of the length of the insert region between HR-A and HR-B in the oligomerization domain, the 30 members were clustered into three classes, Classes A (18), B (10), and C (2). Members within the same class shared highly conserved gene structures and protein motifs. The background expression levels of 11 genes in cold-tolerant rubber-tree clone 93-14 were significantly higher than those in cold-sensitive rubber-tree clone Reken501, while four genes exhibited inverse expression patterns. Upon cold stress, 20 genes were significantly upregulated in 93-114. Of the upregulated genes, HbHsfA2b, HbHsfA3a, and HbHsfA7a were also significantly upregulated in three other cold-tolerant rubber-tree clones at one or more time intervals upon cold stress. Their nuclear localization was verified, and the protein–protein interaction network was predicted. This study provides a basis for dissecting Hsf function in the enhanced cold tolerance of the rubber tree.
