Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description The gene encodes a cinnamyl alcohol dehydrogenase (CAD) enzyme (EC:1.1.1.195).
It is an ortholog of the CAD gene present at the bm1 (brown midrib 1) locus of
maize (GR:0200056). The gene is expressed in the vascular tissue of panicles,
hull, leaf midribs, leaf sheath, internodes and young roots. It is a key enzyme
that regulates lignin content and plays a role in the lignin biosynthesis. In
root tissue, it is expressed in the cortical parenchyma adjacent to the
exodermis and in vascular tissue. The associated phenotype shows, brownish green
lemma and palea at panicle exsertion and deep golden yellow hull at maturity.
Golden internode has more intensified color. (Yellow pigment accumulates in cell
wall). Reduction in lignin content. Simlar to gh1.
