Transfering Shrunken 2 (Sh2) gene coding for adp-glucose pyrophosphorylase enzyme into some inbred maize lines by Agrobacterium tumefaciens mediated gene transfer

Abstract: Viện Công nghệ sinh học, Viện Hàn lâm KH&CN Việt Nam, *nguyenducthanh_pcg@ibt.ac.vn TÓM TẮT: Gen Shrunken 2 (Sh2) ñã ñược xác ñịnh tham gia vào quá trình sinh tổng hợp tinh bột vì gen này mã hóa cho hai tiểu phần lớn của enzyme ADP-glucose pyrophosphorylase, một enzyme ñóng vai trò quan trọng trong ñiều hòa sinh tổng hợp tinh bột ở nhóm cây ngũ cốc. Mục ñích của nghiên cứu này là chuyển gen Sh2 vào một số dòng ngô trồng và tái sinh cây chuyển gen mang gen ñích phục vụ cho nghiên cứu vai trò của gen Sh2 trong v… Show more

“…In addition to the basic research orientation as described above, some laboratories have made efforts to create transgenic plant with drought tolerance (Cao Le Quyen et al, 2009), disease-resistance (Vu Thi Lan et al, 2017), increased productivity (Nguyen Duc Thanh et al, 2015) and quality transgenic crops (Tran Thi Luong et al, 2014;Tran Thi Luong, Nguyen Duc Thanh, 2015). However, the results are still modest.…”

“…Shrunken 2 (Sh2) (Tran Thi Luong et al, 2014) and Brittle 2 (Bt2) genes (Nguyen Thi Thu et al, 2014;Nguyen et al, 2016) encoding ADP-glucose pyrophosphorylase-an enzyme that regulates starch synthesis, were successfully transferred into maize and transgenic maize that increase starch content from 10.12 to 16.04% and yield over 5 tons/ha were obtained. As maize is a low-quality food crop (lack of lysine, tryptophan, low provitamin A including α-carotene, β-carotene and β-cryptoxanthin), with the aim of improving the quality of maize, Tran et al (2017) had transferred the IbOr gene from the Hoang Long sweet potato variety into several maize lines and created transgenic maize plants with increased -carotene content more than 10 fold, contributing to improving the nutritional quality of maize (Tran et al, 2017;Tran Thi Luong & Nguyen Duc Thanh, 2018…”
