Grain Quality and Starch Physicochemical Properties of Chalky Rice Mutant

Rice mutants with altered starch components and properties are important genetic resources for grain quality structure analysis. Accordingly, in the present study, two of transcription factor OsbZIP09 were generated (osbzip09a osbzip09b), rice physicochemical mutant wild-type lines compared. The exhibit a chalky owing to loosely packed, small, spherical granules ventral region endosperm. Furthermore, grain-quality profile analysis showed that deficiency leads increased apparent amylose content but decreased gel consistency. Structural starches revealed contain more amylopectin short chains fewer intermediate chains, leading lower crystallinity gelatinization than those rice. Moreover, presented significantly higher pasting curve corresponding parameters results from this work strongly indicate plays an role fine modification, extend our understanding biosynthesis
