EXPA5 — Solanum lycopersicum

Summary

SOLYC03G115890.3, designated EXPA5 on tomato chromosome 3, encodes an expansin and contains expansin and cellulose-binding domains. The gene is associated with biological processes including cell wall organization, disassembly, and biogenesis, as well as arabinan, pectin, cellulose, and wax metabolism. It is linked to traits such as fruit firmness, size, weight, shape, and color, as well as carotenoid and sugar content, grain size, seedling height, leaf elongation rate, stem elongation, photosynthetic rate, stomatal resistance, and flower abortion. The encoded protein is localized to the extracellular region and membrane. Related genes in other species further connect the family to cell wall modification and growth processes.
