Comprehensive Analysis of GASA Family Members in the Peanut Genome: Identification, Characterization, and Their Expressions in Response to Pod Development

The gibberellic acid-stimulated Arabidopsis (GASA) gene family is essential for plant growth and development, hormone level control, phytohormone signal transmission. Different plants have been shown to contain numerous GASA homologs. However, there no knowledge about these proteins in peanuts. In the current study, we performed a thorough bioinformatics expression analysis found 20, 22, 40 genes by genome-wide analyses of A. hypogaea L., duranensis, ipaensis, respectively. We analyzed predicted physical properties genes. Based on results our phylogenetic analysis, evolutionary tree constructed from AhGASA was divided into seven categories, forming total 14 pairs. According observations, tandem duplication significant factor expansion family. unevenly distributed 20 chromosomes, 17 duplicated were identified. A co-lineage with A/B subgenome identified 69 linear/parallel homologous cis-element revealed that protein crucial responsiveness. materials different size traits at various stages peanut pod transcriptomics RT-qPCR are expressed levels tissue-specific. This finding suggests some may be involved controlling size. study development pods provides first systematic identification peanut. These findings will help future research function cultivated
