Genome-Wide Identification and Expression Analysis of Expansin Gene Family in the Storage Root Development of Diploid Wild Sweetpotato Ipomoea trifida.

ABSTRACT: Expansins play important roles in root growth and development, but investigation of the expansin gene family has not yet been reported in Ipomoea trifida, and little is known regarding storage root (SR) development. In this work, we identified a total of 37 expansins (ItrEXPs) in our previously reported SR-forming I. trifida strain Y22 genome, which included 23 ItrEXPAs, 4 ItrEXPBs, 2 ItrEXLAs and 8 ItrEXLBs. The phylogenetic relationship, genome localization, subcellular localization, gene and protein structure, promoter cis-regulating elements, and protein interaction network were systematically analyzed to reveal the possible roles of ItrEXPs in the SR development of I. trifida. The gene expression profiling in
