ERD5 — Glycine max

Summary

GmERD5 (GLYMA_13G049700V4) on soybean chromosome 13 encodes a proline dehydrogenase with proline oxidase activity, placing it in the FAD-linked oxidoreductase family. The gene is associated with proline breakdown and mitochondrial localisation. It is associated with responses to water, salt, oxidative stress, hypoxia, and dehydration, as well as with stomatal opening, abscission, dehiscence, seed germination, threonine metabolism, tyrosine anabolism, zinc import, homologous recombination, and the TCA cycle. Trait associations include leaf water potential, photosynthetic rate, transpiration rate, stomatal resistance, chlorophyll content, seed weight and size, amino acid and proline content, and leaf chlorosis. Phenotype associations link it to proline accumulation and metabolism, drought tolerance, growth under water deficit, root elongation at low water potential, and NADP/NADPH ratio. Studies of related genes in other species connect the family to dehydration response, salt tolerance, oxidative stress tolerance, and freezing tolerance.
