Germplasm Phenotype:

• ggt1-1 / ggt4-1 / oxp1-1  — The 5-oxoproline (5OP) level in this mutant is not significantly different from the level in the oxp1-1 mutant, suggesting that neither GGT1 nor GGT4 are important upstream enzymes for generating the 5OP used by OXP1.
• ggt4-1  — These mutant plants have reduced levels of gamma-glutamyl transpeptidase activity, especially in the roots, compared with wild-type plants.
• ggt4-1 / opt1-1  — The 5-oxoproline (5OP) level in this mutant is not significantly different from the level in the oxp1-1 mutant, suggesting that GGT4 is not an important upstream enzyme for generating the 5OP used by OXP1.
