AtDFA is dihydrofolate synthase localized in mitochondria, it catalyzes one glutamate added to the dihydropteroate and produces dihydrofolat. AtDFB, AtDFC and AtDFD are folylpolyglutamate synthase localized in plastid, mitochondria and cytosol respectively. A short chain ofγ-linked glutamates can be added by FPGS.Folate molecules exist in vivo mainly as polyglutamates and these are preferred by folate-dependent enzymes.

Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.
