A naturally occurring functional allele of the rice waxy locus has a GT to TT mutation at the 5′ splice site of the first intron

Abstract
In cultivated rice two wild‐type alleles, Wxa and Wxb, predominate at the waxy locus, which encodes granule‐bound starch synthase. The activity of Wxa is 10‐fold higher than that of Wxb at the level ...
