Rice brown spot resistance gene <i>bsr1</i> also confers resistance to bacterial blight by suppressing sucrose efflux

2026-08-07

Abstract excerpt

Brown spot (BS), caused by the fungal pathogen Bipolaris oryzae , is a major disease threatening global rice production. However, the genetic basis of host BS resistance remains unclear. Here, we identified brown spot resistance 1 ( bsr1 ), a quantitative trait locus conferring BS resistance, by map-based cloning. We show that bsr1 encodes a sucrose transporter and that a near-isogenic line carrying bsr1 ( b...
