Journal ArticleDOI
The starch-debranching enzymes isoamylase and pullulanase are both involved in amylopectin biosynthesis in rice endosperm
TL;DR: The results suggest that both debranching enzymes are involved in amylopectin biosynthesis in rice endosperm, and show that the Sugary-1 gene encodes the isoamylase gene of the rice genome.
Journal ArticleDOI
Correlation between activities of starch debranching enzyme and α-polyglucan structure in endosperms of sugary-1 mutants of rice
TL;DR: The results strongly suggest that the reduction in RE activity is involved in the su1 phenotype and that the enzyme plays an essential role in determining the fine structure of the amylopectin molecule.
Journal ArticleDOI
Effect of High Temperature at Ripening Stage on the Reserve Accumulation in Seed in Some Rice Cultivars
TL;DR: The resistance to high-temperature stress and the structural appearance of the imperfect grains caused by a high temperature at the ripening stage were studied using 13 selected cultivars of rice.
Journal ArticleDOI
Expression patterns of genes encoding carbohydrate-metabolizing enzymes and their relationship to grain filling in rice (Oryza sativa L.): comparison of caryopses located at different positions in a panicle.

TL;DR: At the start of caryopsis elongation in both superior and inferior caryopses, the hexose/sucrose ratio increased accompanied by gene expression of vacuolar invertase (INV3), sucrose synthase (RSus1) and ADP-glucose pyrophosphorylase (AGP-L2: D50317).
Journal ArticleDOI
Morphological development of rice caryopses located at the different positions in a panicle from early to middle stage of grain filling.
TL;DR: Differences of inner-integument cell number and endosperm cell number were related to a difference of endos perments size between superior and inferior caryopses, implying the coordinated development of the endOSperm with maternal tissues.
