[PMID: 38682097 PMCID: PMC11052985 DOI: 10.1007/s13205-024-03976-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/13/2024] [Indexed: 05/01/2024] Open
Abstract
TCP transcription factors are known to regulate abiotic stress condition, but their role in V. unguiculata remains unexplored. So, in silico analysis and expression profile of the TCP gene family were performed in V. unguiculata to understand its role in response to heat and drought stress. A genome-wide search detected 28 TCPs (designated as VuTCPs) that were grouped into three subclasses by phylogenetic analysis. Gene structure, synteny, and phylogeny analyses of VuTCPs have shown a typical evolutionary path. One tandem and eight segmental duplication events were identified. Furthermore, identified duplicated, and orthologous VuTCP genes were under strong purifying selection pressure. A total of 15 SSRs were identified in the 12 VuTCPs, while 10 VuTCP genes were regulated by different miRNAs having a major role in abiotic stress tolerance. Analysed physicochemical properties, cis-acting elements, and gene ontology suggested that VuTCPs play various roles, including salinity and drought stress tolerance. qRT-PCR analysis showed that 11 and 15 VuTCPs were upregulated under drought and salinity stress conditions, respectively. Our findings provide comprehensive insights into the genomic characterization of the VuTCPs gene family in V. unguiculata, offering a foundation for understanding their structure, evolution, and role in abiotic stress tolerance.

Çelik S. Gene expression analysis of potato drought-responsive genes under drought stress in potato ( Solanum tuberosum L.) cultivars. PeerJ 2024; 12:e17116. [PMID: 38525286 PMCID: PMC10960530 DOI: 10.7717/peerj.17116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 02/26/2024] [Indexed: 03/26/2024] Open
Abstract
The potato (Solanum tuberosum L.), an important field crop consumed extensively worldwide, is adversely affected by abiotic stress factors especially drought. Therefore, it is vital to understand the genetic mechanism under drought stress to decrease loose of yield and quality . This trial aimed to screen drought-responsive gene expressions of potato and determine the drought-tolerant potato cultivar. The trial pattern is a completely randomized block design (CRBD) with four replications under greenhouse conditions. Four cultivars (Brooke, Orwell, Vr808, Shc909) were irrigated with four different water regimes (control and three stress conditions), and the gene expression levels of 10 potato genes were investigated. The stress treatments as follows: Control = 100% field capacity; slight drought = 75% field capacity; moderate drought = 50% field capacity, and severe drought 25% field capacity. To understand the gene expression under drought stress in potato genotypes, RT-qPCR analysis was performed and results showed that the genes most associated with drought tolerance were the StRD22 gene, MYB domain transcription factor, StERD7, Sucrose Synthase (SuSy), ABC Transporter, and StDHN1. The StHSP100 gene had the lowest genetic expression in all cultivars. Among the cultivars, the Orwell exhibited the highest expression of the StRD22 gene under drought stress. Overall, the cultivar with the highest gene expression was the Vr808, closely followed by the Brooke cultivar. As a result, it was determined that potato cultivars Orwell, Vr808, and Brooke could be used as parents in breeding programs to develop drought tolerant potato cultivars.

Abstract
Hsp70 proteins function as molecular chaperones, regulating various cellular processes in plants. In this study, a genome-wide analysis led to the identification of 22 Hsp70 (MeHsp70) genes in cassava. Phylogenetic relationship studies with other Malpighiales genomes (Populus trichocarpa, Ricinus communis and Salix purpurea) classified MeHsp70 proteins into eight groups (Ia, Ib, Ic, Id, Ie, If, IIa and IIb). Promoter analysis of MeHsp70 genes revealed the presence of tissue-specific, light, biotic and abiotic stress-responsive cis-regulatory elements showing their functional importance in cassava. Meta-analysis of publically available RNA-seq transcriptome datasets showed constitutive, tissue-specific, biotic and abiotic stress-specific expression patterns among MeHsp70s in cassava. Among 22 Hsp70, six MeHsp70s viz., MecHsp70-3, MecHsp70-6, MeBiP-1, MeBiP-2, MeBiP-3 and MecpHsp70-2 displayed constitutive expression, while three MecHsp70s were induced under both drought and cold stress conditions. Five MeHsp70s, MecHsp70-7, MecHsp70-11, MecHsp70-12, MecHsp70-13, and MecHsp70-14 were induced under drought stress conditions. We predicted that 19 MeHsp70 genes are under the regulation of 24 miRNAs. This comprehensive genome-wide analysis of the Hsp70 gene family in cassava provided valuable insights into their functional roles and identified various potential Hsp70 genes associated with stress tolerance and adaptation to environmental stimuli.

Characterization of HSP70 family in watermelon ( Citrullus lanatus): identification, structure, evolution, and potential function in response to ABA, cold and drought stress.

[PMID: 37323666 PMCID: PMC10265491 DOI: 10.3389/fgene.2023.1201535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 05/22/2023] [Indexed: 06/17/2023] Open
Abstract
Watermelon (Citrullus lanatus) as a crop with important economic value, is widely cultivated around the world. The heat shock protein 70 (HSP70) family in plant is indispensable under stress conditions. However, no comprehensive analysis of watermelon HSP70 family is reported to date. In this study, 12 ClHSP70 genes were identified from watermelon, which were unevenly located in 7 out of 11 chromosomes and divided into three subfamilies. ClHSP70 proteins were predicted to be localized primarily in cytoplasm, chloroplast, and endoplasmic reticulum. Two pairs of segmental repeats and 1 pair of tandem repeats existed in ClHSP70 genes, and ClHSP70s underwent strong purification selection. There were many abscisic acid (ABA) and abiotic stress response elements in ClHSP70 promoters. Additionally, the transcriptional levels of ClHSP70s in roots, stems, true leaves, and cotyledons were also analyzed. Some of ClHSP70 genes were also strongly induced by ABA. Furthermore, ClHSP70s also had different degrees of response to drought and cold stress. The above data indicate that ClHSP70s may be participated in growth and development, signal transduction and abiotic stress response, laying a foundation for further analysis of the function of ClHSP70s in biological processes.

Abstract
Plant heat shock protein 90 (Hsp90) participates in various physiological processes including protein folding, degradation, and signal transduction. However, the DcHsp90 gene family in carnation (Dianthus caryophyllus L.) has not been systematically analyzed. We thoroughly examined and comprehensively analyzed the carnation DcHsp90 gene family in this study and discovered 9 DcHsp90 genes. Based on the phylogenetic examination, DcHsp90 proteins may be divided into two groups. DcHsp90 structural features were similar but varied between groups. Promoter analysis revealed the presence of many cis-acting elements, most of which were connected to growth and development, hormones, and stress. DcHsp90 genes may play distinct functions in heat stress response, according to gene expression analyses. The DcHsp90-6 was isolated, and its role in the reaction to heat stress was studied. Thermotolerance and superoxide dismutase activity in transgenic seedlings were enhanced by Arabidopsis overexpression of DcHsp90-6. After heat stress, transgenic plants' electrolyte leakage and malondialdehyde levels were much lower than wild-type plants. Furthermore, overexpression of DcHsp90-6 altered the expressions of stress-responsive genes such as AtHsp101, AtHsp90, AtGolS1, AtRS4/5, and AtHsfB1. This study provides comprehensive information on the DcHsp90 gene family and suggests that overexpressed DcHsp90-6 positively regulates thermotolerance highlighting the adaptation mechanism of carnation under heat stress.

Abstract
Fruit orchards are frequently irrigated with brackish water. Irrigation with poor quality water is also a major cause of salt accumulation in soil. An excess of salts results in stunted growth, poor yield, inferior quality and low nutritional properties. Melatonin is a low molecular weight protein that shows multifunctional, regulatory and pleiotropic behavior in the plant kingdom. Recently, its discovery brought a great revolution in sustainable fruit production under salinity-induced environments. Melatonin contributed to enhanced tolerance in Zizyphus fruit species by improving the plant defense system's potential to cope with the adverse effects of salinity. The supplemental application of melatonin has improved the generation of antioxidant assays and osmolytes involved in the scavenging of toxic ROS. The tolerance level of the germplasm is chiefly based on the activation of the defense system against the adverse effects of salinity. The current study explored the contribution of melatonin against salinity stress and provides information regarding which biochemical mechanism can be effective and utilized for the development of salt-tolerant germplasm in Zizyphus.

Genome-wide analysis of Hsp40 and Hsp70 gene family in four cotton species provides insights into their involvement in response to Verticillium dahliae and abiotic stress. Front Genet 2023; 14:1120861. [PMID: 36777720 PMCID: PMC9909605 DOI: 10.3389/fgene.2023.1120861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 01/09/2023] [Indexed: 01/27/2023] Open
Abstract
Introduction: Cotton is an important economic crop to provide natural fibers as raw materials to textile industry, and is significantly affected by biotic and abiotic stress during the whole growth stage, in which Verticillium wilt (VW) caused by Verticillium dahliae is one of the most destructive disease to lead to a significant yield reduction. Heat shock proteins (Hsps) are important molecular chaperones, and play crucial roles in plant growth, development, resistance to biotic and abiotic stress. Hsp40 and Hsp70 are two key Hsps in cell chaperone network, however, the function and regulatory mechanism of Hsp40 and Hsp70 members in VW resistance and abiotic stress in cotton are largely unknown. Methods and Results: Herein, a systematic and comprehensive analysis of Hsp40s and Hsp70s in four cotton species of Gossypium arboretum, G. raimondii, G. hirsutum, and G. barbadense were performed. A total of 291 Hsp40s and 171 Hsp70s identified in four Gossypium species. Sequence analysis revealed that all Hsp40 proteins contained J domain that provides the binding sites to Hsp70. Protein-protein interaction prediction analysis displayed that GhHsp40-55 might interact with GhHsp70-2 and GhHsp70-13, suggesting their potential function as protein complex. Promoter cis-acting element analysis demonstrated that multiple cis-elements related to disease and stress response consists in GhHsp40 and GhHsp70 promoters. Further expression analysis showed that eight GhHsp40s (Hsp40-2,4,8,11,20,23,53,55) and seven GhHsp70s (Hsp70-2,3,6,8,13,19,22) were up-regulated after V. dahliae infection. In addition, five GhHsp40s (Hsp40-2,8,11,53,55) and four GhHsp70s (Hsp70-3,6,8,13) were up-regulated after salt treatment, six GhHsp40s (Hsp40-4,11,20,23) and three GhHsp70s (Hsp70-2,8,19) were up-regulated after drought treatment, four GhHsp40s (Hsp40-2,11,20,23) and four GhHsp70s (Hsp70-3,6,19,22) were up-regulated after temperature treatment, suggesting these Hsps have possible important function in the process of abiotic stress response. Discussion: Our results lay a foundation for understanding the function of Hsp40 and Hsp70 in the resistance against V. dahliae and abiotic stress, and elucidating the regulatory mechanism of the protein complex, evolution and molecular mechanism under stress.

Abstract
Lentinula edodes (L. edodes), one of the most popular edible mushrooms in China, is adversely affected by high temperature. Heat shock proteins (HSPs) play a crucial role in regulating the defense responses against the abiotic stresses in L. edodes. Some HSPs in L. edodes have been described previously, but a genome-wide analysis of these proteins is still lacking. Here, the HSP genes across the entire genome of the L. edodes mushroom were identified. The 34 LeHSP genes were subsequently classified into six subfamilies according to their molecular weights and the phylogenetic analysis. Sequence analysis showed that LeHSP proteins from the same subfamily have conserved domains and one to five similar motifs. Except for Chr 5 and 9, 34 LeHSPs genes were distributed on the other eight chromosomes. Three pairs of paralogs were identified because of sequence alignment and were confirmed as arising from segmental duplication. In LeHSPs' promoters, different numbers of heat shock elements (HSEs) were predicted. The expression profiles of LeHSPs in 18N44 and 18 suggested that the thermo-tolerance of strain 18N44 might be related to high levels of LeHSPs transcript in response to heat stress. The quantitative real-time PCR (qRT-PCR) analysis of the 16 LeHSP genes in strains Le015 and Le027 verified their stress-inducible expression patterns under heat stress. Therefore, these comprehensive findings provide useful in-depth information on the evolution and function of LeHSPs and lay a theoretical foundation in breeding thermotolerant L. edodes varieties.

Abstract
Nuclear factor-Y (NF-Y) is an important transcription factor in the plant species, which potentially provides a higher level of functional diversity including for abiotic stress tolerance. The genome-wide study and expression analysis of NF-Y gene family in Ziziphus, an elite abiotic stress-tolerant species, assist bioprospecting of genes. Here, a total of 32 NF-Y (8 NF-YA, 15 NF-YB, and 9 NF-YC) genes were identified in genome-wide search of Z. jujuba genome. Physicochemical properties, cellular localization, gene structure, chromosomal location, and protein motifs were analyzed for structural and functional understanding. Identified 12 NF-Ys were responsible for the expansion of NF-Y gene family by tandem duplication in Z. jujuba. Phylogenetic and comparative physical mapping of Z. jujuba NF-Ys with its orthologs illustrated evolutionary and functional insights into NF-Y gene family. A total of 45 perfect microsatellites (20bp to 40bp) were extracted across the ZjNF-Y genes. The promoter and gene ontology study suggested that Z. jujuba NF-Y gene family is functionally diverse and could play a wide-ranging role in plant abiotic stress, development, and cellular processes. An expression study revealed that large numbers of the NF-Ys are differentially expressed in response to drought and salinity. The total 15 and 18 ZjNF-Y genes that are upregulated under drought and salinity stress, respectively, are the potential candidates for further functional analysis for development of climate-resilient crops. The present study established a base for understanding the role of NF-Ys in Z. jujuba under abiotic stress conditions and paved a way for further research.
