PETB — Sorghum bicolor

Summary

SORBI_3003G168800, also known as PETB or psbH, encodes a protein of the PSII_PsbH family. This sorghum gene on chromosome 3 is associated with phosphate ion binding and localizes to the photosystem II complex, chloroplast thylakoid membrane, and plastid. It has been linked to diverse biological processes including protein stabilization, gibberellin biosynthesis, endocytosis, auxin transport, cell division, and regulation of metabolism. The gene is associated with water use efficiency, photosynthetic rate, and plant height. Studies of related genes in other species connect the family to additional traits including leaf width, plant vigor, leaf length, quantum yield, grain weight, grain yield, chlorophyll content, heat tolerance, starch content, and cytoplasmic male sterility.
