Project description:Glutathione S-transferases (GSTs) are ubiquitous enzymes that are encoded by a large gene family, and they contribute to the detoxification of endogenous or xenobiotic compounds and oxidative stress metabolism in plants. Although the GSTs gene family has been reported in many land plants, our knowledge of the evolution and function of the willow GSTs is still limited. In this study, 22 full-length GST genes were cloned from Salix babylonica and divided into three classes based on the conserved domain analysis, phylogenetic tree and gene structure: tau, phi and DHAR. The tissue-specific expression patterns were substantially different among the tau and phi GSTs. The Salix GST proteins showed functional divergences in the substrate specificities, substrate activities and kinetic characteristics. The site-directed mutagenesis studies revealed that a single amino acid mutation (Ile/Val53?Thr53) resulted in the lowest activity of SbGSTU7 among the Salix GSTs. These results suggest that non-synonymous substitution of an amino acid at the putative glutathione-binding site may play an important role in the divergence of enzymatic functions of Salix GST family.

Expression data from Salix matsudana

Project description:Salt responsive genes were identified in chinese willow (Salix matsudana) after the plants were treated with 100 mM NaCl. for 48 hours We used microarrays to identify genes responsible for combating salt stress. Those up-regulated during the NaCl treatment may protect the plants from damages caused by salt stress. 2 month-old S. matsudana plants which were treated with 100 mM NaCl and control plants were used for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain salt responsive genes that protect the plants from stress injury.Those differentially expressed genes identified by the microarray would help to understand the mechanism of S. matsudana reacting to salt stress.
