Genome- and Transcriptome-Wide Identification of C3Hs in Common Bean ( L.) and Structural and Expression-Based Analyses of Their Functions During the Sprout Stage Under Salt-Stress Conditions.

CCCH (C3H) zinc-finger proteins are involved in plant biotic and abiotic stress responses, growth and development, and disease resistance. However, studies on genes in L. (common bean) are limited. Here, 29 protein-encoding genes, located on 11 different chromosomes, were identified in . A phylogenetic analysis categorized the s into seven subfamilies on the basis of distinct features, such as exon-intron structure, -regulatory elements, and MEME motifs. A collinearity analysis revealed connections among the s in the same and different species. The genes showed tissue-specific expression patterns during the sprout stage, as assessed by real-time quantitative PCR (RT-qPCR). Using RNA-sequencing and RT-qPCR data, s were identified as being enriched through Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses in binding, channel activity, and the spliceosome pathway. These results provide useful information and a rich resource that can be exploited to functionally characterize and understand s. These , especially those enriched in binding, channel activity, and the spliceosome pathway will further facilitate the molecular breeding of common bean and provide insights into the correlations between and salt-stress responses during the sprout stage.
