LCD — Capsicum annuum

Summary

CaLCD (T459_02448) on pepper chromosome 1 encodes an L-cysteine desulfhydrase 2 with cysteine desulfurase, selenocysteine lyase, L-cysteine desulfhydrase and molybdopterin cofactor sulfurase activities. It is associated with abscisic acid anabolism, sulfur metabolism, the ascorbate-glutathione cycle, iron incorporation into metallo-sulfur clusters, molybdenum incorporation into metallo-pterin complexes, response to selenium ion, heat, glucose and osmotic stress, stomatal movement, fruit ripening, cell growth, chloroplast stroma protein import, detoxification, sugar-mediated signalling and auxin signalling. The gene is linked to leaf water potential, photosynthetic rate, respiration rate, chloroplast development, plant growth and development, and salt tolerance. Related genes in other species are linked to abscisic acid biosynthesis, drought and UV-B tolerance, seed dormancy, stomatal closure, and resistance to Botrytis cinerea and insect herbivory.
