An Arabidopsis gene with homology to glutathione S-transferases is regulated by ethylene.
A cDNA clone obtained from Arabidopsis leaf RNA encodes a 24 kDa protein with homology to glutathione S-transferases (GST). It is most homologous with a tobacco GST (57% identity). In Arabidopsis, expression of GST mRNA is regulated by ethylene. Exposure of plants to ethylene increased the abundance of GST mRNA, while treatment with norbornadiene had the reverse effect. Ethylene had no effect on the mRNA level in ethylene-insensitive etr1 plants. The abundance of this mRNA increased with the age of plants. DNA hybridizations indicate that GSTs are encoded by a large multigene family in Arabidopsis.
