PR5 — Oryza sativa Indica Group

Summary

BGIOSGA035790 (PR5, OiPR5) on indica rice chromosome 12 encodes a thaumatin-like protein, a member of the osmotin/thaumatin-like superfamily. This gene is associated with defence response to fungi, killing of cells of other organisms, signal transduction, the TCA cycle, and phenylpropanoid anabolism, and its product localises to the extracellular space. It has also been linked to grain yield. Studies of related genes in other species, such as RASTL and pathogenesis-related protein 1 sequences, connect the thaumatin-like family to defence responses.
