Identification of the xyloglucan endotransglycosylase/hydrolase genes and the role of PagXTH12 in drought resistance in poplar.

ABSTRACT: The xyloglucan endotransglycosylase/hydrolase (XTH) gene family plays a crucial role in plant cell wall remodeling, facilitating growth and structural changes. However, the divergence of paralogous genes among different species of Populus remains inadequately understood. This study investigates the phylogenetic relationships and expression characteristics of XTH genes in two Populus species: Populus trichocarpa and Populus alba × P. glandulosa '84K'. Forty-one XTHs were identified in P. trichocarpa and 38 and 33 members in the subgenome A and G of '84K' poplar, respectively. Gene expression analysis demonstrated differences among paralogous genes within the same subgenome and between orthologous genes across species, likely influenced by var
