“…Among the less abundant amino acids, cysteine, methionine, and tryptophan stand out. Leucine abundance is important for several reasons, such as contribution to the stability of proteins in the membrane, the interaction of the protein with other molecules, regulation of plant metabolism, metabolic pathways, perception of the environment, signal transduction, and a marked presence in leucine-rich repeat containing immune receptor proteins (Ariza-Suarez et al, 2023; Wang et al, 2024). Serine, on the other hand, is important as a site for phosphorylation, a chemical change that can activate or inactivate speci c functions in response by cells to changes in their environment at both a biotic and abiotic level (Rawat et al, 2023).…”

Mildew Resistance Locus O (MLO) proteins play a crucial role in plant-pathogen interactions, especially with regard to susceptibility to powdery mildew (PM). In this study, structural characteristics of MLO genes and proteins in several plant species and phylogenetic relationships were investigated, highlighting evolutionary patterns and characteristics responsible for the function of these proteins. To this end, MLO genes associated with plant susceptibility to PM and their putative promoter regions (PPRs) were investigated in relation to their genomic characteristics and composition of cis-regulatory elements (CREs). From the amino acid sequences, various biochemical and cytological properties were studied, also obtaining a phylogenetic reconstruction. Both the topology of the segments (extracellular, transmembrane and cytoplasmic) of the MLO proteins and the identity matrices of these regions were analyzed. MLO proteins have a basic character, are rich in leucine, and present structural patterns such as functional domains, structural motifs, amino acid composition, and subcellular localization. As for the evolutionary highlights, the phylogenetic analysis revealed groupings consistent with the taxonomic classification of some families, such as Poaceae, Solanaceae and Brassicaceae. Analysis of identity matrices demonstrated that segments of the extracellular space are less conserved than those of the cytoplasmic space, with the transmembrane regions being the most conserved. The genes present a relatively conserved pattern in the size and distribution of introns/exons, and in relation to PPRs, specific patterns of CREs constitution were observed in the different clades, which implies the potential complexity of regulating the expression of these genes.

“…The gene structures of CsGH3 were visualized and analyzed using the TBtools software. The upstream 2000 bp sequences of CsGH3 gene family members were extracted using the TBtools software [ 45 , 46 ]. Plant CARE ( http://bioinformatics.psb.ugent.be/webtools/plantcare/html/ ) online software was employed to predict cis -acting elements in these sequences [ 47 ].…”

To comprehensively understand the characteristics of the GH3 gene family in tea plants (Camellia sinensis), we identified 17 CsGH3 genes and analyzed their physicochemical properties, phylogenetic relationships, gene structures, promoters, and expression patterns in different tissues. The study showed that the 17 CsGH3 genes are distributed on 9 chromosomes, and based on evolutionary analysis, the CsGH3 members were divided into three subgroups. Gene duplication analysis revealed that segmental duplications have a significant impact on the amplification of CsGH3 genes. In addition, we identified and classified cis-elements in the CsGH3 gene promoters and detected elements related to plant hormone responses and non-biotic stress responses. Through expression pattern analysis, we observed tissue-specific expression of CsGH3.3 and CsGH3.10 in flower buds and roots. Moreover, based on predictive analysis of upstream regulatory transcription factors of CsGH3, we identified the potential transcriptional regulatory role of gibberellin response factor CsDELLA in CsGH3.14 and CsGH3.15. In this study, we found that CsGH3 genes are involved in a wide range of activities, such as growth and development, stress response, and transcription. This is the first report on CsGH3 genes and their potential roles in tea plants. In conclusion, these results provide a theoretical basis for elucidating the role of GH3 genes in the development of perennial woody plants and offer new insights into the synergistic effects of multiple hormones on plant growth and development in tea plants.

“…Increasing resistance to salt and drought is a key focus in the development of peanut varieties. Several peanut gene families have been studied, due to the peanut genome database being accessible [ 33 , 34 , 35 ]. Although the SPL family has been discovered and identified in various plants, there is still limited research on the SPL gene family in the peanut.…”

SPL (SQUAMOSA promoter binding protein-like), as one family of plant transcription factors, plays an important function in plant growth and development and in response to environmental stresses. Despite SPL gene families having been identified in various plant species, the understanding of this gene family in peanuts remains insufficient. In this study, thirty-eight genes (AhSPL1-AhSPL38) were identified and classified into seven groups based on a phylogenetic analysis. In addition, a thorough analysis indicated that the AhSPL genes experienced segmental duplications. The analysis of the gene structure and protein motif patterns revealed similarities in the structure of exons and introns, as well as the organization of the motifs within the same group, thereby providing additional support to the conclusions drawn from the phylogenetic analysis. The analysis of the regulatory elements and RNA-seq data suggested that the AhSPL genes might be widely involved in peanut growth and development, as well as in response to environmental stresses. Furthermore, the expression of some AhSPL genes, including AhSPL5, AhSPL16, AhSPL25, and AhSPL36, were induced by drought and salt stresses. Notably, the expression of the AhSPL genes might potentially be regulated by regulatory factors with distinct functionalities, such as transcription factors ERF, WRKY, MYB, and Dof, and microRNAs, like ahy-miR156. Notably, the overexpression of AhSPL5 can enhance salt tolerance in transgenic Arabidopsis by enhancing its ROS-scavenging capability and positively regulating the expression of stress-responsive genes. These results provide insight into the evolutionary origin of plant SPL genes and how they enhance plant tolerance to salt stress.
