摘要

Cell wall remodeling mediated by xyloglucan endotransglucosylase/hydrolase (XET/XTH) is an important determinant of growth, development and stress responses in plants. XET/XTH splits xyloglucan chains connecting cellulose microfibrils and links with other existing ones in the cell wall. In the current study, gene-specific primers were used to amplify and sequence the xet23 gene from the ginger (Zingiber officinale) plant. Furthermore, a genome-wide survey revealed the size and diversity of this family in ginger, with 132 XET sequences. A phylogenetic analysis segregated these sequences into six major clusters and allowed the annotation of 42 hypothetical XET sequences. Physicochemical research and atomic-level structural models of representative XETs provided further insights into the inherent variability and functional evolution involving catalytic sites of XET/XTHs.
