LCD — Solanum lycopersicum

Summary

SlLCD (SOLYC07G066480.3) on tomato chromosome 7 encodes a molybdenum cofactor sulfurase with selenocysteine lyase, L-cysteine desulfhydrase, and cysteine desulfurase activities. The gene is associated with hydrogen sulfide and lycopene biosynthesis, molybdenum cofactor assembly, iron-sulfur cluster formation, and downregulation of photosynthesis. It has been linked to numerous agronomic traits including fruit weight and size, lycopene and carotenoid content, chlorophyll content, photosynthetic rate, water use efficiency, stomatal resistance, leaf water potential, root system architecture (root length, hair density, lateral root number), shoot fresh weight, and plant growth. Associations also include responses to water, selenium, nutrients, osmotic stress, UV-B, cadmium, and Botrytis cinerea, as well as abscisic acid biosynthesis, seed germination and dormancy, chloroplast development, and stomatal development and closure.
