24-Epibrassinolide ameliorates the effects of boron toxicity on Arabidopsis thaliana (L.) Heynh by activating an antioxidant system and decreasing boron accumulation
Surgun, Yonca; Çöl, Bekir; Bürün, Betül (Springer Heidelberg, 2016)Brassinosteroids (BRs) play a significant role in alleviating the negative effects of various environmental stresses and in promoting the growth and development of plants. In this study, we investigated the effects of ... -
The ameliorative effects of 24-epibrassinolide on shoot organogenesis inhibition occurring under NaCl-stressed conditions in cultures of cotyledon and hypocotyl explants of tomato (Lycopersicon esculentum Mill.)
Yılmaz-Gökdoğan, Emel; Bürün, Betül (Univ Zagreb, Fac Science, Div Biology, 2017)In this study, possible effects of 24-epibrassinolide (24-epiBL) pretreatment against NaCl stress were investigated using in vitro shoot organogenesis from cotyledon and hypocotyl explants in M-28 tomato hybrid cultivar. ... -
