[Progress in regulation of rice Wx gene expression].

The granule-bound starch synthase(GBSS) is encoded by the rice Wx gene, which is the major gene for control of amylase synthesis of. This paper briefly introduced the progress in regulation of rice Wx gene expression at transcriptional level and post-transcriptional level. At the same time the influence of transgene, genetic background and temperature condition on Wx gene expression in rice was discussed. Finally some urgent questions were suggested for the further study on regulation of rice Wx gene expression.
