  • Marker assisted pyramiding of Bph6 and Bph9 into elite restorer line 93-11 and development of functional marker for Bph9., 2017, Rice (N Y).

• Key message
  • BPH9 activates salicylic acid- and jasmonic acid-signaling pathways in rice plants and confers both antixenosis and antibiosis to BPH
  • BPH9 encodes a rare type of nucleotide-binding and leucine-rich repeat (NLR)-containing protein that localizes to the endomembrane system and causes a cell death phenotype
  • The resulting Bph6 and Bph9 pyramided line LuoYang69 had stronger antixenotic and antibiosis effects on BPH and exhibited significantly enhanced resistance to BPH than near isogenic lines NIL-Bph6 and NIL-Bph9
  • LuoYang69 derived hybrids, harboring heterozygous Bph6 and Bph9 genes, also conferred high level of resistance to BPH
  • The development of Bph6 and Bph9 pyramided line LuoYang69 provides valuable resource to develop hybrid rice with highly and durable BPH resistance
  • The identified Bph9 containing cultivars can be used as new sources for BPH resistance breeding programs
  • Marker assisted pyramiding of Bph6 and Bph9 into elite restorer line 93-11 and development of functional marker for Bph9.
  • The development of functional markers will promote MAS of Bph9
• Connection
  • BPH9, MAS~OsMAS, Marker assisted pyramiding of Bph6 and Bph9 into elite restorer line 93-11 and development of functional marker for Bph9., Here, we developed near isogenic lines of Bph9 (NIL-Bph9) by backcrossing elite cultivar 93-11 with Pokkali (harboring Bph9) using marker-assisted selection (MAS)
  • BPH9, MAS~OsMAS, Marker assisted pyramiding of Bph6 and Bph9 into elite restorer line 93-11 and development of functional marker for Bph9., Subsequently, we pyramided Bph6 and Bph9 in 93-11 genetic background through MAS
  • BPH9, MAS~OsMAS, Marker assisted pyramiding of Bph6 and Bph9 into elite restorer line 93-11 and development of functional marker for Bph9., The development of functional markers will promote MAS of Bph9
