Ultramorphometric study of the plastids in apical tuber cells of original and transgenic potato plants treated with ambiol

“…The observed distinctions between the responses of cell plastids of the original and transgenic plants treated with ambiol agree well with the previous data [24] on changes in mitochondria of original and transgenic potato plants under the same experimental conditions. Presumably, this is due to changes in the physiological state of apical tuber cells caused by expression of the defensin gene.…”

“…This work continues our research into mechanisms underlying the action of the antioxidant ambiol in original and defensin gene-transfected plants of potato cultivar Desire [9,15,16,18,19,24]. It was found earlier that ambiol was capable of regulating growth through either stimulation or inhibition of tuber germination of original and transgenic plants depending on the concentration [9].…”

“…Hence our interest in the antioxidant ambiol (2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole dihydrochloride), first synthesized at the Institute of Biochemical Physics, Russian Academy of Sciences, which displays anti-stress properties and acts as a growth regulator [5,6,[8][9][10][11][12][13]. It is demonstrated that ambiol influences formation, growth, and development processes in plants [4,5,[14][15][16][17], the content of phytohormones in plant tissues, and activities of H + -ATPase in the plasmalemmata of potato tuber cells [9,[18][19][20][21]. Studies of the effects of individual antioxidants, particularly ionol [22,23] and ambiol [24], on the plant organism were initiated.…”
