Description
Summary:The ABC1K  gene family (activity of BC1 complex kinase), found in bacteria, archaea, and eukaryotes, plays a vital role in regulating cellular metabolism. Despite its significance, the evolutionary history and functional diversity of the ABC1K gene family little in Brassica crops, are not well understood. Chinese cabbage, a crop of Brassica genus extensively cultivated and consumed in East Asia, has a complex evolutionary history that includes polyploidization and whole-genome duplication. Through comprehensive analyses of gene structures, phylogenetic relationships, chromosomal locations, microsynteny, gene duplication, and gene expression, the ABC1K gene family in Chinese cabbage was characterized. We identified 25 members of the Chinese cabbage ABC1K gene family, all of which harbor the AarF domain. Notably, we further reported the occurrence of gene fusion, resulting in the formation of the BraraABC1K15-2 gene in Brassica . Additionally, we observed that the ABC1K genes displayed highly tissue-specific patterns, with significantly higher levels observed in flowers and leaves compared to other tissues. Remarkably, genes BraraABC1K4 and Brara ABC1K 14 were found for the first time to participate in plant photosynthesis. The findings presented here will help to understand the functions of ABC1K genes in plant development, growth, and stress response.
