Description The Waxy (Wx) gene encodes a granule-bound starch synthase (GBSS) that plays a
key role in the amylose synthesis of rice. It is expressed in the seed endosperm
and pollen grains, that carry starch grains. At sub-cellular level the protein
is localized in the amyloplasts. This gene undergoes alternative splicing of its
transcripts suggesting that the amylose content of rice endosperm is regulated
at the level of Wx transcript processing, and more specifically, at the stage of
intron I excision from the Wx pre-mRNA. The alternative splicing is affected by
the change in temperature. It is a single copy gene in rice. The phenotype shows
white and non-translucent endosperm which turns brown to the iodine staining.
