Comment 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 starcg 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.
