Characterization and Coexpression Analysis of the Family Genes in Related to Leaf Development.

TIFYs are plant-specific transcription factors that contain the TIFY structural domain and play an important role in plant leaf growth and development. However, the role played by TIFY in ( Salisb.) leaf development has not been investigated. In this study, 23 genes were identified in . Phylogenetic analyses of the genes showed clustering into three groups (JAZ, ZIM, and PPD). The TIFY domain was shown to be conserved. JAZ was mainly expanded via wholegenome triplication (WGT) in Based on analyses of the genes in nine species, we found that JAZ has a closer relationship with PPD, in addition to appearing the most recently and expanding most rapidly, leading to the rapid expansion of TIFYs in . In addition, their different evolution types were discovered. Different gene expressions showed the distinct and corresponsive expression patterns of the in different stages of tissue and leaf development. Finally, The qPCR analysis revealed that the expression of and showed an upward trend and high expression throughout leaf development. Further co-expression analysis indicated that might be more important for the development of leaves. This information will be valuable when exploring the molecular mechanisms of s in plants.
