ATJ11 — Solanum lycopersicum

Summary

SlATJ11, the tomato orthologue of ATJ11 on chromosome 4, encodes a DnaJ domain-containing protein that binds heat shock proteins, ATP, and zinc. The gene is associated with placentation, carotenoid breakdown and metabolism, cell wall disassembly, phosphoglyceride metabolism, nitrogen fixation, polyketide and melatonin anabolism, the MVA pathway, hormone and secondary metabolite biosynthesis, chloroplast fission, fermentation, and response to water and potassium ions. It is linked to harvest index, fruit weight, shape, and color, leaf number, sugar and protein content, germination rate, chlorophyll content, net photosynthetic rate, quantum yield, water use efficiency, and drought tolerance. The protein localises to the vacuole, ER, and cytoplasm. Related genes in other species link the family to chaperone functions in chloroplasts.
