SSSIVb gene, which is the group of Soluble Starch Synthase enzyme, concerns to synthesis amylopectin in the seed of rice. In this research, we will examine the process of mRNA splicing intron 6, 7, 8 and 9 of SSSIVb gene and observe the expression of gene in development of seed at 5, 10 and 15 days after flowering (DAF) in 5 varieties of the rice which are RD10, Chai Nat 1, Niew Phrae 1, San-pah-tawng 1 and Suphan Buri 60. All of those varieties have different quality of cooking. From the experimental, we found that Chai Nat 1 had splicing in 5 DAF rice seeds but no expression in 10 and 15 DAF rice seeds. In Suphan Buri 60 had splicing in 10 DAF rice seeds but no expression in 5 and 15 DAF rice seeds. And RD 10, Niew Phrae 1, San Pah Tawng 1 had splicing... |
