Gene Details:

• MSU gene ID: LOC_Os09g26960
• RAPdb gene ID: Os09g0441400
• Gene Symbol: EP
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The breeding of japonica varieties with erect-pose panicle (EP) has recently progressed in the northern part of China, because these varieties exhibit a far higher grain yield than the varieties with normal-pose panicle (NP).
• Experimental results showed that EP gene markedly enhanced grain yield, chiefly by increasing number of secondary branches and number of grains on the secondary branch.
• Identification and characterization of the erect-pose panicle gene EP conferring high grain yield in rice (Oryza sativa L.).
• EP gene also produced a remarkable increase in grain density.
• Based on previous studies, map-based cloning of EP locus was conducted using Liaojing5, Toyonishiki, their F(2) population, and a pair of near-isogenic lines for EP locus (ZF14 and WF14) derived from the cross between the two varieties; consequently, the STS marker H90 was found to completely cosegregate with panicle pose.
