Genetic and Evolutionary Analysis of Purple Leaf Sheath in Rice.

ABSTRACT:

Background

Anthocyanin accumulates in many plant tissues or organs, in rice for example leading to red, purple red and purple phenotypes for protection from damage by biotic and abiotic stresses and for reproduction. Purple leaf, leaf sheath, stigma, pericarp, and apiculus are common in wild rice and landraces and occasionally found in modern cultivars. No gene directly conferring anthocyanin deposited in a purple leaf sheath has yet been isolated by using natural variants. An F2 population derived from ssp. japonica cv. Tainung 72 (TNG72) with purple leaf sheath (PSH) crossed with ssp. indica cv. Taichung Sen 17 (TCS17) with green leaf sheath (GSH) was utilized to isolate a gene conferring leaf sheath color.
