Type QTL
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description The QTL that increases grain productivity in rice, Gn1a, is a gene for cytokinin
oxidase/dehydrogenase (OsCKX2), an enzyme that degrades the phytohormone
cytokinin. Reduced expression of OsCKX2 causes cytokinin accumulation in
inflorescence meristems and increases the number of reproductive organs,
resulting in enhanced grain yield. The grain yield increasing allele is from
Habataki. This QTL has been originally identified from 96 backcross inbred lines
(BILs) derived from the cross between Habataki and Koshihikari, but its position
has been displayed on the JRGP Nipponbare/Kasalath RFLP map.
