- Connection
- FLO2, OsISA1~OsPHS8, Three novel alleles of FLOURY ENDOSPERM2 FLO2 confer dull grains with low amylose content in rice., The allelic diversity of flo2 perturbed the expression of starch synthesis-related genes including OsAGPL2, OsAGPS2b, OsGBSSI, OsBEI, OsBEIIb, OsISA1, and OsPUL
- OsBEIIa~OsSBE4~RBE4, OsISA1~OsPHS8, Sugary Endosperm is Modulated by Starch Branching Enzyme IIa in Rice Oryza sativa L.., Genetic analyses indicated that the sug-h mutant phenotype was controlled by a complementary interaction of two recessive genes, Isoamylase1 (OsISA1), which was reported previously, and Starch branching enzyme IIa (OsBEIIa), which was newly identified in this study
- OsBEIIa~OsSBE4~RBE4, OsISA1~OsPHS8, Sugary Endosperm is Modulated by Starch Branching Enzyme IIa in Rice Oryza sativa L.., CONCLUSIONS: Complementary interactions between the starch biosynthesis genes OsISA1 and OsBEIIa determine the mild sugary endosperm mutant, sugary-h, in rice
