Expression of the Ta6-SFT gene in Brassica napus under drought stress

doi:10.11686/cyxb20140518

Abstract

Abstract:

Fructan is thought to be one of the important regulators involved in plant tolerance to various abiotic stresses. In this study the Triticum aestivum gene for sucrose: fructan 6-fructosyltransferase synthesis (Ta6-SFT) was transferred into Brassica napus, driven by the rd29A promoter and mediated by Agrobacterium tumefaciens. Subsequently, transgenic plants were identified using PCR, southern blot and northern dot blot tests. In order to test the effect of the Ta6-SFT gene on transgenic plants under drought stress, non-transgenic plants (control) and 7 transgenic plants (T₁ generation) were exposed to 36 days of moisture stress. Expression of Ta6-SFT was tested using a semi-quantitative RT-PCR 36 days after treatment and 2 days after re-watering. Fructan concentration and physiological traits including relative conductivity and MDA content were analyzed at the same times. The results showed Ta6-SFT expression level is positively associated with fructan content and resistance to drought stress, indicating that the Ta6-SFT gene could enhance resistance to drought in transgenic plants.
