摘要： 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 Y22 SR development revealed that ItrEXPAs and ItrEXLBs were down-regulated, and ItrEXPBs were up-regulated while ItrEXLAs were not obviously changed during the critical period of SR expansion, and might be beneficial to SR development. Combining the tissue-specific expression in young SR transverse sections of Y22 and sweetpotato tissue, we deduced that ItrEXLB05, ItrEXLB07 and ItrEXLB08 might be the key genes for initial SR formation and enlargement, and ItrEXLA02 might be the key gene for root growth and development. This work provides new insights into the functions of the expansin gene family members in I. trifida, especially for EXLA and EXLB subfamilies genes in SR development.
