Golden 2-like transcription factor contributes to the major QTL against rice black-streaked dwarf virus disease

A major resistance QTL was identified on chromosome 6 in rice variety Wuke; both overexpression and knockdown experiments confirmed that OsGLK1 is the candidate gene for association with Rice black-streaked dwarf virus disease. Rice black-streaked dwarf virus disease is one of the most destructive rice viral diseases in China and East Asia. Progress has been limited in RBSDVD resistance breeding due to inadequate knowledge on the underlying functional genes. In this study, a major QTL for RBSDV (rice black-streaked dwarf virus) independent of SBPH (small brown planthopper) resistance was mapped in a 1.8 Mb interval on chromosome 6 by using an F
