Table 1 Molecular weight distribution of starch isolated from endosperm during seedling growtha

From: Long branch-chains of amylopectin with B-type crystallinity in rice seed with inhibition of starch branching enzyme I and IIb resist in situ degradation and inhibit plant growth during seedling development
