PR5 — Oryza sativa Indica Group

Summary

BGIOSGA035787 (PR5, OiPR5) in Indica rice encodes a thaumatin-like protein, a member of the osmotin/thaumatin-like superfamily. The gene is associated with defence responses to fungi, killing of cells of other organisms, and signal transduction, as well as with the TCA cycle and phenylpropanoid anabolism. Its product is localised to the extracellular space. PR5 has also been linked to grain yield. Studies of related genes in other species, including RASTL and pathogenesis-related protein 1 family members, connect the thaumatin-like protein family to plant defence.
