CLA — Solanum lycopersicum

Summary

SOLYC01G067890.4 (CLA, also known as DXS1, DXS2, and DEF) encodes a protein with DXP-synthase activity and transketolase domains, placing it in the 1-deoxy-D-xylulose-5-phosphate synthase family. In tomato, the gene is associated with carotenoid biosynthesis, sesquiterpene and monoterpene production, herbivore resistance, and trichome density. It is linked to numerous agronomic traits including fruit color, lycopene and carotene content, fruit weight and set, seed yield, protein content, and size, as well as leaf weight, plant height, photosynthetic rate, and responses to high temperature and drought. The encoded protein is associated with chloroplast and peroxisomal localization and with processes such as isoprenoid metabolism, phytoene anabolism, and pigment metabolism. Studies of related genes in other species connect the family to chloroplast differentiation, isoprenoid biosynthesis, and disease resistance.
