英文摘要
Rice leaf sheaths accumulate transiently starch, which is degraded after the heading and utilized for the grain filling. Therefore, elucidation of the mechanism of starch remobilization at the post-heading stage in leaf sheaths is important for improving the rice grain yield. In this study, we identified two beta-amylases, OsBAM2 and OsBAM3, as plastid-targeted starch-metabolizing enzymes. In addition, our results raise the possibility that OsBAM2 and OsBAM3 genes may have an important role in the starch remobilization in leaf sheaths at the post-heading stage.
