Негрецкий В. А. Инициация флорального морфогенеза у растений различной фотопериодической чувствительности и особенности экспрессии Са2+-зависимой протеинкиназы С [Електронний ресурс] / В. А. Негрецкий, Е. И. Ковзун // Доповiдi Національної академії наук України. - 2007. - № 6. - С. 162-164 . - Режим доступу: http://nbuv.gov.ua/UJRN/dnanu_2007_6_30 We study the <$E alpha>-isoform of Ca-dependent protein kinase C (CaPKC) expression during the induction of flowering in the leaves of different photoperiodic sensitive plants. As a result, the expression of Ca-dependent proteine kinase C in the leaves of 2 biotypes of tobacco and perilla plants is shown. The 5 long-day induction promoted the CaPKC expression in the leaves of long-day tobacco Nicotiana silvestris L. plants by 143 %. A similar activation of the PKC expression was observed after 5 short-day (SD) inductions in SD plants of tobacco M. Mamoth and perilla. This allows us to discuss the Ca-dependent PKC participation in mechanisms of signal transduction during the photoperiodic induction and its involving in the initial stages of floral morphogenesis.
