Abstract

Apomixis is a common reproductive characteristic of plants, and are plant-specific transcription factors known to regulate embryonic development. However, the genome-wide analysis and function prediction of family genes in are unclear. In this study, 36 transcription factors were identified in the genome of , among which 15 genes belonged to the RKD subfamily and 21 belonged to the NLP subfamily. Duplication events of genes were mainly segmental duplication, and synteny analysis revealed a close phylogenetic relationship between and . The analysis of cis-elements indicated that genes may be involved in the regulation of the embryonic development of by responding to plant hormones such as abscisic acid, auxin, and gibberellin. Results of a real-time PCR showed that the expression levels of most genes were significantly increased from flowers to young fruits. Protein-protein interaction network analysis further revealed the potential roles of the ZaRWP-RK proteins in apomixis. Collectively, this study is expected to improve our understanding of transcription factors and provide a theoretical basis for future investigations into the genes and their regulatory mechanisms in the apomixis process of .
