Variabilitatea somaclonală la plantele de tutun transgenic. In: Studia Universitatis Moldaviae. Seria Ştiinţe Reale şi ale Naturii: Biologie. Chimie. Revista științifică. 2007, nr. 1. pp. 75-79.

It was shown that five lines had greater plant dimensions in comparison to the control ones. Also, in all transgenic tobacco lines there were detected higher accumulation of hydrogen peroxide invascular tissues. All these suggest that observed changes appeared as the result of plant transformation and regeneration at morphological and biochemical levels.rovariabilitatea somaclonalăArticle
