Meta-analysis of identified genomic regions and candidate genes underlying salinity tolerance in rice (Oryza sativa L.). Sci Rep 2024; 14:5730.

Abstract
Rice output has grown globally, yet abiotic factors are still a key cause for worry. Salinity stress seems to have the more impact on crop production out of all abiotic stresses. Currently one of the most significant challenges in paddy breeding for salinity tolerance with the help of QTLs, is to determine the QTLs having the best chance of improving salinity tolerance with the least amount of background noise from the tolerant parent. Minimizing the size of the QTL confidence interval (CI) is essential in order to primarily include the genes responsible for salinity stress tolerance. By considering that, a genome-wide meta-QTL analysis on 768 QTLs from 35 rice populations published from 2001 to 2022 was conducted to identify consensus regions and the candidate genes underlying those regions responsible for the salinity tolerance, as it reduces the confidence interval (CI) to many folds from the initial QTL studies. In the present investigation, a total of 65 MQTLs were extracted with an average CI reduced from 17.35 to 1.66 cM including the smallest of 0.01 cM. Identification of the MQTLs for individual traits and then classifying the target traits into correlated morphological, physiological and biochemical aspects, resulted in more efficient interpretation of the salinity tolerance, identifying the candidate genes and to understand the salinity tolerance mechanism as a whole. The results of this study have a huge potential to improve the rice genotypes for salinity tolerance with the help of MAS and MABC.

Genes (Basel) 2024; 15:147.

Abstract
IQM is a plant-specific calcium-binding protein that plays a pivotal role in various aspects of plant growth response to stressors. We investigated the IQM gene family and its expression patterns under diverse abiotic stresses and conducted a comprehensive analysis and characterization of the AeIQMs, including protein structure, genomic location, phylogenetic relationships, gene expression profiles, salt tolerance, and expression patterns of this gene family under different abiotic stresses. Based on phylogenetic analysis, these 10 AeIQMs were classified into three distinct subfamilies (I-III). Analysis of the protein motifs revealed a considerable level of conservation among these AeIQM proteins within their respective subfamilies in kiwifruit. The genomic distribution of the 10 AeIQM genes spanned across eight chromosomes, where four pairs of IQM gene duplicates were associated with segmental duplication events. qRT-PCR analysis revealed diverse expression patterns of these AeIQM genes under different hormone treatments, and most AeIQMs showed inducibility by salt stress. Further investigations indicated that overexpression of AeIQMs in yeast significantly enhanced salt tolerance. These findings suggest that AeIQM genes might be involved in hormonal signal transduction and response to abiotic stress in Actinidia eriantha. In summary, this study provides valuable insights into the physiological functions of IQMs in kiwifruit.

Kumar A, Singh S, Mishra A. Genome-wide identification and analyses of the AHL gene family in rice ( Oryza sativa). 3 Biotech 2023; 13:248. [PMID: 37366497 PMCID: PMC10290627 DOI: 10.1007/s13205-023-03666-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Accepted: 06/11/2023] [Indexed: 06/28/2023] Open
Abstract
AHL (AT-HOOK MOTIF CONTAINING NUCLEAR LOCALIZED) family members play a critical role in stress resistance regulation by DNA-protein and protein-protein interactions in a number of plant biological processes. Using genomic data, an attempt was made to evaluate AHL genes in rice. Using a genome database, we performed in silico detection and characterization of AHL family genes in rice. The data of the gene were obtained from the Rice Genome Annotation Project (RGAP) database. The rice genome data were analyzed using bioinformatics software. The main objectives of the research are genome-wide recognition, expression, structural examination, phylogenetic analysis of AHL gene family, classification of AHL proteins into different classes based on motif and domain composition, analysis of promoter regions to identify stress and phytohormone-associated cis-elements, expression analysis of OsAHL genes in diverse tissues and stressful situations and understanding the roles of AHLs in controlling rice plant development. The genome-wide recognition, expression, and structural examination of the AHL gene family were undertaken in this research to evaluate the structural activities of AHLs in rice. From the Oryza sativa genome, 26 AHL genes have been identified. WoLF PSORT analysis predicted different subcellular localizations for these proteins, including nuclear, cytoplasmic, chloroplast, and endoplasmic reticulum. According to a phylogenetic study, rice AHLs resulted in two clades: Clade-A with no introns (excluding OsAHL15 and OsAHL21) and Clade-B with four introns. Depending on the AT-hook motif (s) (AHM) and PPC/DUF 296 domain composition, the AHL proteins are categorized into the following three classes: Type-I, Type-II, and Type-III, among Type-I AHLs constituting Clade-A, Type-II, and Type-III creating Clade-B. Type-I was the largest gene family, representing 57.69% of OsAHL genes. The exon-intron organization within clades of OsAHL genes was similar. Multiple sequence alignment identified 15 conserved motifs, including AT-hook motifs and the PPC domain, suggesting DNA-binding functionality. OsAHL genes were distributed across 12 chromosomes, with chromosome 2 and 8 harboring the highest number of genes. Gene duplication analysis revealed eight paralogous pairs, indicating evolutionary divergence between 13.32 and 35.59 million years ago. The emergence of OsAHL paralogous pairs was favored by purifying selection. Synteny analysis between rice and Arabidopsis demonstrated collinearity among AHL gene pairs, implying comparable structure and function in the two species. The role of stress- and phytohormone-associated cis-elements in the OsAHL genes was discovered by promoter analysis. OsAHL genes participated in various biological processes, with a prominent involvement in cellular and metabolic processes. They exhibited a significant enrichment in binding functions, including a substantial proportion of transcription regulators. OsAHL genes displayed diverse expression patterns in different tissues and under abiotic stress conditions. According to their expression patterns, the majority of OsAHLs of Clade-B were expressed mainly in the pistil indicating their roles in flower formation, while Clade-A OsAHLs had the minimal expression in pistil and highly expressed in embryos, indicating that the AHLs within each clade had the same expression patterns. Some OsAHL genes were also expressed in stressful situations, such as cold, salt, and drought. Protein interaction analysis revealed networks involving AHL proteins and other proteins, suggesting their participation in phytohormone responses, abiotic stress, and plant development. In this work, 26 OsAHL genes were found in the genome of rice. Rice OsAHLs were grouped into two phylogenetic groups. It is further divided into three types on the basis of the motif and domain composition. At various phases of development, the expression analysis of OsAHLs showed numerous variations in expression levels in diverse tissues and stress situations. Our findings shed light on the significant roles of AHLs in controlling rice plant development.

Abstract
IQM, a plant-specific calmodulin-binding protein, plays multiple roles in plant growth and development. Although a comprehensive analysis has been carried out on the IQM family genes in Arabidopsis and rice, the number and functions of IQM genes in other species have not been explored. In this study, we identified 15 members of the soybean (Glycine max) IQM gene family using BLASTP tools. These members were distributed on 12 soybean chromosomes and constitute six pairs caused by fragment duplication events. According to phylogeny, the 15 genes were divided into three subfamilies (I, II, and III), and members of the same subfamily had similar gene and protein structures. Yeast two-hybrid experiments revealed that the IQ motif is critical for the binding of GmIQM proteins to GmCaM, and its function is conserved in soybean, Arabidopsis, and rice. Based on real-time PCR, the soybean IQM genes were strongly induced by PEG and NaCl, suggesting their important biological functions in abiotic stress responses. Overall, this genome-wide analysis of the soybean IQM gene family lays a solid theoretical foundation for further research on the functions of GmIQM genes and could serve as a reference for the improvement and breeding of soybean stress resistance traits.

Abstract
The regulation of reactive oxygen species (ROS) levels in plants is ensured by mechanisms preventing their over accumulation, and by diverse antioxidants, including enzymes and nonenzymatic compounds. These are affected by redox conditions, posttranslational modifications, transcriptional and posttranscriptional modifications, Ca2+, nitric oxide (NO) and mitogen-activated protein kinase signaling pathways. Recent knowledge about protein-protein interactions (PPIs) of antioxidant enzymes advanced during last decade. The best-known examples are interactions mediated by redox buffering proteins such as thioredoxins and glutaredoxins. This review summarizes interactions of major antioxidant enzymes with regulatory and signaling proteins and their diverse functions. Such interactions are important for stability, degradation and activation of interacting partners. Moreover, PPIs of antioxidant enzymes may connect diverse metabolic processes with ROS scavenging. Proteins like receptor for activated C kinase 1 may ensure coordination of antioxidant enzymes to ensure efficient ROS regulation. Nevertheless, PPIs in antioxidant defense are understudied, and intensive research is required to define their role in complex regulation of ROS scavenging.

Abstract
Myosins are essential components of organelle trafficking in all the eukaryotic cells. Myosin driven movement plays a vital role in the development of pollen tubes, root hairs and root tips of flowering plants. The present research characterized the myosin genes in Arabidopsis thaliana and Helianthus annuus by using different computational tools. We discovered a total of 50 myosin genes and their splice variants in both pant species. Phylogenetic analysis indicated that myosin genes were divided into four subclasses. Chromosomal location revealed that myosin genes were located on all five chromosomes in A. thaliana, whereas they were present on nine chromosomes in H. annuus. Conserved motifs showed that conserved regions were closely similar within subgroups. Gene structure analysis showed that Atmyosin2.2 and Atmyosin2.3 had the highest number of introns/exons. Gene ontology analysis indicated that myosin genes were involved in vesicle transport along actin filament and cytoskeleton trafficking. Expression analysis showed that expression of myosin genes was higher during the flowering stage as compared to the seedling and budding stages. Tissue specific expression indicated that HanMYOSIN11.2, HanMYOSIN16.2 were highly expressed in stamen, whereas HanMYOSIN 2.2, HanMYOSIN 12.1 and HanMYOSIN 17.1 showed higher expression in nectary. This study enhance our understanding the function of myosins in plant development, and forms the basis for future research about the comparative genomics of plant myosin in other crop plants.

The Butterfly Effect: Mild Soil Pollution with Heavy Metals Elicits Major Biological Consequences in Cobalt-Sensitized Broad Bean Model Plants. Antioxidants (Basel) 2022; 11:antiox11040793. [PMID: 35453478 PMCID: PMC9028058 DOI: 10.3390/antiox11040793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/15/2022] [Accepted: 04/15/2022] [Indexed: 11/17/2022] Open
Abstract
Among the heavy metals (HMs), only cobalt induces a polymorphic response in Vicia faba plants, manifesting as chlorophyll morphoses and a ‘break-through’ effect resulting in the elevated accumulation of other HMs, which makes Co-pretreated broad bean plants an attractive model for investigating soil pollution by HMs. In this study, Co-sensitized V. faba plants were used to evaluate the long-term effect of residual industrial pollution by examining biochemical (H2O2, ascorbic acid, malondialdehyde, free proline, flavonoid, polyphenols, chlorophylls, carotenoids, superoxide dismutase) and molecular (conserved DNA-derived polymorphism and transcript-derived polymorphic fragments) markers after long-term exposure. HM-polluted soil induced a significantly higher frequency of chlorophyll morphoses and lower levels of nonenzymatic antioxidants in Co-pretreated V. faba plants. Both molecular markers effectively differentiated plants from polluted and control soils into distinct clusters, showing that HMs in mildly polluted soil are capable of inducing changes in DNA coding regions. These findings illustrate that strong background abiotic stressors (pretreatment with Co) can aid investigations of mild stressors (slight levels of soil pollution) by complementing each other in antioxidant content reduction and induction of DNA changes.
