Application

Application Comment Organism
agriculture analysis of 352 Vietnamese rice cultivars reveals a wide range of variation in apparent amylose content and the expression level of granule-bound starch synthase I. Alleles can be classified into seven groups that reflect differences in apparent amylose content. The very low and low apparent amylose content levels are tightly associated with a G to T in the first intron whereas intermediate and high amylose is associated with a T genotype at a single-nucleotide polymorphism in exon 10. The correlation between the combination of T genotype at single-nucleotide polymorphism in the first intron, C in exon 6, or C in exon 10 is predominant among low amylose rice varieties. The low amylose properties of Vietnamese local rice germplasm are attributable to spontaneous mutations at exons, and not at the splicing donor site Oryza sativa
