“…It is known for its high yield, strong adaptability, and wide cultivation areas, making it a significant staple crop and industrial raw material [ 23 , 24 ]. The completion of the genome sequencing of sweet potato ( I. batatas (L.) Lam., 2n = B 1 B 1 B 2 B 2 B 2 B 2 = 6x = 90) [ 25 ] and its two diploid species, I. trifida NCNSP0306 (2n = 2x = 30) and I. triloba NCNSP0323 (2n = 2x = 30) [ 26 ], has made it possible to analyze the sweet potato gene family using bioinformatics [ 27 , 28 , 29 , 30 , 31 , 32 ]. However, the DA1-like gene family in sweet potatoes has not been reported in these whole-genome studies.…”

The DA1-like gene family plays a crucial role in regulating seed and organ size in plants. The DA1 gene family has been identified in several species but has not yet been reported in sweet potatoes. In this study, nine, eleven, and seven DA1s were identified in cultivated sweet potato (Ipomoea batatas, 2n = 6x = 90) and its two diploid wild relatives, I. trifida (2n = 2x = 30) and I. triloba (2n = 2x = 30), respectively. The DA1 genes were classified into three subgroups based on their phylogenetic relationships with Arabidopsis thaliana and Oryza sativa (rice). Their protein physiological properties, chromosomal localization, phylogenetic relationships, gene structure, promoter cis-elements, and expression patterns were systematically analyzed. The qRT-PCR results showed that the expression levels of four genes, IbDA1-1, IbDA1-3, IbDA1-6, and IbDA1-7, were higher in the sweet potato leaves than in the roots, fiber roots, and stems. In our study, we provide a comprehensive comparison and further the knowledge of DA1-like genes in sweet potatoes, and provide a theoretical basis for functional studies.
