Genome-Wide Identification of DlGRAS Family and Functional Analysis of <i>DlGRAS10/22</i> Reveal Their Potential Roles in Embryogenesis and Hormones Responses in <i>Dimocarpus longan</i>.

ABSTRACT: GRAS family plays a critical role in plant growth and stress responses. In this study, we identified 47 GRAS (DlGRAS) genes in the longan genome and conducted a comprehensive bioinformatics analysis of these genes. RNA-seq analysis revealed that the expression of these DlGRAS genes differed during early SE and across various longan tissues. The quantitative real-time PCR (qRT-PCR) results indicated that the DlGRAS genes exhibited differential expression during the early SE of longan, with most of them showing high expression at the globular embryo (GE) stage. Under GA₃ treatment, the transcript levels of DlGRAS12/15 decreased significantly. In contrast, exogenous ABA promoted the expression of DlGRAS6/10/23, indicating that DlG
