The effect of free proline accumulation on the content of photosynthetic pigments in transgenic wheat plants

Aim. To analyze the effect of L-proline accumulation on chlorophyll content in transgenic wheat plants with a double-stranded RNA suppressor proline dehydrogenase gene under physiological and stress conditions. Methods. Agrobacterium-mediated transformation planta; biochemical determination free content; spectrophotometric photosynthetic pigments mathematical statistics. Results. It was shown that leaves conditions 1.7-1.9 times higher compared to original genotype. Under drought, this aminoacid increased non-transformed genotypes by 2.9-3.1 times, – 4.5-4.9 times. The amount flag their lines did not differ significantly, while drought first them it 1.1-1.2 less than second. Drought reduced total genotype 85-90 %, conditions, no significant changes were found plants. Conclusions. established soil increase genetically modified non-transgenic ones is accompanied an (by 10-15 %), which indicates better efficiency pigment apparatus stressful
