AMT — Zea mays

Summary

ZM00001EB070250 (ZmAMT, also known as GLDT) encodes an aminomethyltransferase (EC 2.1.2.10) that is a component of the glycine cleavage system, localised to the mitochondrion. The gene is associated with photorespiration, glycine decarboxylation and breakdown, and heat acclimation and response. Annotated associations link ZmAMT to plant growth and development traits, oxidative stress response, abscisic acid sensitivity, and salt tolerance. Phenotypic connections include seedling lethality under ambient CO₂, reduced photosynthetic activity, impaired growth in air, stem rust severity, acquired thermotolerance, and ABA-mediated growth inhibition. Studies of related genes in other species link the family to basal immunity and thermo-resilience, while sequence similarity in other cereals connects the family to grain yield, grain number, plant height, nitrogen and protein content, and root hair length.
