<i>SgR1</i>, Encoding a Leucine-Rich Repeat Containing Receptor-like Protein, Is a Major Aphid (<i>Schizaphis graminum</i>) Resistance Gene in Sorghum.

ABSTRACT: Greenbug, Schizaphis graminum, is one of the important cereal aphid pests of sorghum in the United States and other parts of the world. Sorghum bicolor variety PI 607900 carries the Schizaphis graminum resistance (SgR1) gene that underlies plant resistance to greenbug biotype I (GBI). Now, the SgR1 has been determined as the major gene conferring greenbug resistance based on the strong association of its presence with the resistance phenotype in sorghum. In this study, we have successfully isolated the SgR1 gene using a map-based cloning approach, and subsequent molecular characterization revealed it encodes a leucine-rich repeat containing receptor-like protein (LRR-RLP). According to DNA sequence analysis, the SgR1 gene are conserved among
