Isolation and characterization of an Arabidopsis mutant that overaccumulates O-Acetyl-L-Ser.

Plant physiology - 1 Oct 2004

Ohkama-Ohtsu Naoko, Kasajima Ichiro, Fujiwara Toru, Naito Satoshi

Abstract excerpt

O-Acetyl-l-Ser (OAS) is a positive regulator for the expression of sulfur (S) deficiency-inducible genes. In this study, through the isolation and analysis of Arabidopsis mutants exhibiting altered expression of S-responsive genes, we identified a thiol reductase as a regulator of the OAS levels. Ethyl methanesulfonate-mutagenized M2 seeds of transgenic Arabidopsis NOB7 carrying a chimeric S-responsive promoter...
