THE ACTION OF BRASSINOLIDE ON SKOTOMORPHOGENESIS OF TRANSGENIC TOBACCO PLANTS (NICOTIANA TABACUM L.)
A comparative analysis of the effect brassinolide (BL) on the morphogenesis of the etiolated seedlings of nontransgenic (SR1) and three transgenic monoinsertion lines (IL18 № 7-1, IL18 № 7-11, and IL18 № 28-3) of Nicotiana tabacum L. on the early stages of ontogenesis was carry out. BL (10–6 M) significantly inhibited the growth of root and hypocotyl as at the non-transgenic, so and the genetically modified plants. The inhibitory effect of BL for all studied plant object decreased by lower concentration. The difference in the growth responses of etiolated seedlings for three transgenic and non-transgenic lines caused by exogenous BL was detected.
