ERD5 — Asparagus officinalis

Summary

A4U43_C04F9530 (AoERD5) on asparagus chromosome 4 encodes a proline dehydrogenase with proline oxidase activity, a FAD-linked oxidoreductase localized to mitochondria. The gene is associated with proline breakdown, somatic embryogenesis, embryogenesis, cellular response to hypoxia, response to oxidative stress, osmotic response, cell differentiation, defence response to bacteria, and response to thirst. It has been connected to respiration rate, photosynthetic rate, proline accumulation, proline metabolism, growth under water deficit, hypersensitive response, NADP/NADPH ratio, root elongation at low water potential, dehydration response, drought tolerance, and abiotic stress response. Studies of related genes in other species link the family to traits including carbon content, specific leaf weight, drought recovery, leaf weight, leaf relative water content, shoot dry weight, amino acid content, shoot fresh weight, relative growth rate, stem diameter, flavonoid content, proline content, quantum yield, osmotic response sensitivity, net photosynthetic rate, transpiration rate, high and low temperature stress responses, abiotic plant stress response, stomatal resistance, chlorophyll content, plant height, oxidative stress response, disease tolerance, photochemical quenching, salt tolerance, and glyphosate sensitivity.
