GSNOR — Solanum lycopersicum

Summary

SOLYC09G064370.4, designated GSNOR (also known as SlGSNOR or ADHIII) on tomato chromosome 9, encodes an S-(hydroxymethyl)glutathione dehydrogenase with NAD(P)+ and NAD+ activity, a zinc-binding aldo-keto reductase belonging to the alcohol dehydrogenase family. The protein localises to the cytosol and is associated with reactive nitrogen species metabolism, S-nitrosylation, methanal catabolism, fermentation, and the pentose-phosphate shunt. It has been linked to numerous agronomically important traits including fruit yield, fruit ripening and size, carotenoid content, chlorophyll content, photosynthetic rate, plant height, root length and thickness, seed dormancy and development, flowering time, and tolerance to drought, salinity, alkaline stress, and iron deficiency. Additional associations include tube development, root regeneration, aerenchyma formation, pigment and cytokinin anabolism, and regulation of autophagy.
