Rose A1-Overexpression Plant Accumulate Anthocyanins and Resist Insect Attack

Abstract:

Anthocyanins have important biological functions, it can help plants resist diseases invasion and pest attack. In this study, we got Rosea1-transformed snapdragon by Agrobacterium-mediated method. Anthocyanins content in the transgenic snapdragon was significantly elevated. Compared with wild-type plant, the snapdragon with anthocyanins accumulation in plant effectively reduced aphid attack in farmland. Similarly, Over-expression of Rosea1 in heterologous plant tobacco also lead to anthocyanins synthesis and the transgenic tobacco showed resistance to aphids. Therefore, improving the content of anthocyanins in plants using genetic engineering technology is a useful measure for plant protection.
