    • Expression of an osmotin-like protein from Solanum nigrum confers drought tolerance in transgenic soybean 

      Weber, Ricardo Luís Mayer; Strohm, Beatriz Wiebke; Bredemeier, Christian; Margis-Pinheiro, Márcia; Brito, Giovani Greigh de; Rechenmacher, Ciliana; Bertagnolli, Paulo Fernando; Sá, Maria Eugênia Lisei de; Campos, Magnólia de Araújo; Amorim, Regina Maria Santos de; Beneventi, Magda Aparecida; Margis, Rogerio; Grossi-de-Sá, Maria Fátima; Bodanese-Zanettini, Maria Helena (2014) [Artigo de periódico]
      Background: Drought is by far the most important environmental factor contributing to yield losses in crops, including soybeans [Glycine max (L.) Merr.]. To address this problem, a gene that encodes an osmotin-like protein ...

    • MicroRNAs play critical roles during plant development and in response to abiotic stresses 

      Lima, Júlio César de; Morais, Guilherme Loss de; Margis, Rogerio (2012) [Artigo de periódico]
      MicroRNAs (miRNAs) have been identified as key molecules in regulatory networks. The fine-tuning role of miRNAs in addition to the regulatory role of transcription factors has shown that molecular events during development ...

    • Plant responses to stresses : role ascorbate peroxidase in the antioxidant protection 

      Caverzan, Andréia; Passaia, Gisele; Rosa, Sílvia Barcellos; Ribeiro, Carolina Werner; Lazzarotto, Fernanda; Margis-Pinheiro, Márcia (2012) [Artigo de periódico]
      When plants are exposed to stressful environmental conditions, the production of Reactive Oxygen Species (ROS) increases and can cause significant damage to the cells. Antioxidant defenses, which can detoxify ROS, are ...
