MDH — Beta vulgaris subsp. vulgaris

Summary

BVRB_9G222480 (BvMDH) encodes a protein with malate dehydrogenase activity and NAD-L-malate dehydrogenase activity, belonging to the lactate dehydrogenase/glycoside hydrolase family 4 C-terminal domain family. This sugar beet gene on chromosome 9 is associated with the TCA cycle, malate metabolism, regulation of photorespiration, and regulation of fatty acid beta-oxidation. It is linked to chloroplast development, meristem growth and structural organization, root morphogenesis, and both male and female gamete generation. Associations include respiration rate, photosynthetic rate, high temperature stress response, oxidative stress response, herbicide sensitivity, disease tolerance, zinc sensitivity, iron concentration, and salt tolerance. The encoded protein localizes to plastid stroma, chloroplast inner membrane, microbodies, and the Ycf2/FtsHi complex. Related genes in other species link the family to metabolic flexibility, heat stress response, chloroplast development under heat stress, and zinc deficiency tolerance.
