Xyloglucan endotransglucosylase/hydrolase 25 positively regulates the lead tolerance in <i>Raphanus sativus</i>.

ABSTRACT: Raphanus sativus, an important root vegetable native to China, is widely cultivated for its nutritional value and diverse applications. However, it is highly sensitive to lead (Pb) stress, with Pb predominantly accumulating in the roots. Previous studies have highlighted the pivotal role of xyloglucan endotransglucosylase/hydrolase (XTH) in plant responses to heavy metal stress. Despite this, a comprehensive identification, molecular characterization, and functional analysis of the XTH gene family in R. sativus has been lacking. In this study, 28 XTH genes were identified in R. sativus. Gene structure analysis revealed the presence of eight conserved motifs, along with variations in exon-intron organization and chromosomal distribution across all chromoso
