Application

EC Number Application Comment Organism
2.4.1.18 biotechnology RNAi technology is applied to suppress the expression of starch branching enzyme IIa and IIb and to increase amylose content in maize endosperm, and stably inherit high-amylose maize lines Zea mays
2.4.1.18 biotechnology RNAi technology is applied to suppress the expression of starch branching enzyme IIa and IIb and to increase amylose content in maize endosperm, and stably inherit high-amylose maize lines. Transgenic maize lines with amylose content of up to 55.89% are produced, which avoid the significant decreases in starch content and grain yield that occur in high-amylose starch branching enzyme IIb gene mutant Zea mays

2.4.1.18 additional information application of RNAi technology for improving amylose content in maize endosperm through the suppression of the ZmSBEIIa and ZmSBEIIb genes by hairpin SBEIIRNAi constructs. These SBEIIRNAi transgenes lead to the downregulation of ZmSBEII expression and SBE activity to various degrees and altered the morphology of starch granule Zea mays

2.4.1.18 malfunction inhibitory effects of these hpSBEIIRNA constructs on the expression of SBEIIa and SBEIIb in maize endosperm, levels of ZmSBEII transcription and SBE activity in kernels of transgenic plants, overview. The transgenic maize lines show increased content of amylopectin chains with high-molecular weight compared to decreased low-molecular weight chains Zea mays
