Molecular evolution of the rice blast resistance gene Pi-ta in invasive weedy rice in the USA.

PloS one - 1 Jan 2011

Lee Seonghee, Jia Yulin, Jia Melissa, Gealy David R, Olsen Kenneth M, Caicedo Ana L

Abstract excerpt

The Pi-ta gene in rice has been effectively used to control rice blast disease caused by Magnaporthe oryzae worldwide. Despite a number of studies that reported the Pi-ta gene in domesticated rice and wild species, little is known about how the Pi-ta gene has evolved in US weedy rice, a major weed of rice. To investigate the genome organization of the Pi-ta gene in weedy rice and its relationship to gene flow...
