Protein Variants

Protein Variants	Comment	Organism
additional information	construction of isozyme mutants, tgg1-3, tgg2-1, and tgg1-3/tgg2-1. Abscisic acid, methyl jasmonate, and H2O2 induce stomatal closure in wild type, tgg1-3 and tgg2-1, but fail to induce stomatal closure in tgg1-3 tgg2-1. All mutants and wild-type show Ca2+-induced stomatal closure and abscisic acid-induced reactive oxygen species production	Arabidopsis thaliana
