Última Determination of endogenous IAA and carbohydrates during the induction and development of protocorm-like bodies of Cattleya tigrina A. Richard Biological Sciences De Conti, Daniela; Corredor-Prado, Jenny Paola; Roecker Junior, Djalma; Suzuki, Rogério Mamoru; Guerra, Miguel Pedro; Pescador, Rosete.  Tissue culture techniques have been employed for orchid mass propagation by means of the morphogenetic route of protocorm like-bodies (PLBs). This study aimed to analyze and compare Indole-acetic acid (IAA) and sugar endogenous levels in protocorm-like bodies (PLBs) induction and development in Cattleya tigrina, in order to better understand this process and to optimize micropropagation procedure protocols. Leaves grown on MS (Murashige and Skoog) culture medium, suplemented with 9 μM TDZ for PLBs induction and development were collected after 0, 2, 7, 14, 30, 60 and 100 days of cultivation, for further analysis. Increase of IAA and reduction of sugar levels are strongly related to morphogenetic response, that is, PLBs formation over the preexisting ones...

Richard Biological Sciences Almeida, Vivian; Fraga, Hugo Pacheco de Freitas; Navarro, Bruno Bachiega; Guerra, Miguel Pedro; Pescador, Rosete. Cattleya tigrina is endemic to the Atlantic forest biome and classified as vulnerable in the Red Book of Brazilian Flora. In vitro techniques comprise valuable tools for the conservation of endangered plant species. The aim of the present study was to evaluate the morphological features, global DNA methylation levels and free polyamines during protocorm-like bodies (PLBs) induction of C. tigrina. Along with that, an efficient protocol for in vitro propagation of this species is proposed. The first evidences of PLBs induction in C. tigrina occurred at seven days in culture, starting from the basal portion of the leaf abaxial surface. A hypomethylation marked the beginning of cell differentiation, followed by an increased global DNA methylation at 35 days in...

Ano: 2017 URL: http://periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/36656 Dynamics of proteins, carbohydrates and global DNA methylation patterns during induction of nodular cluster cultures from seeds of Vriesea reitzii Agronomy Corredor, Jenny; De Conti, Daniela; Guerra, Miguel Pedro; Dal Vesco, Lirio Luiz; Pescador, Rosete. Tissue culture techniques have been employed for bromeliad mass propagation by means of the morphogenetic route of nodular cluster cultures (NCs). This study aimed to assess protein, carbohydrate and global DNA methylation (GDM) level dynamics during NCs induction from Vriesea reitzii seeds. Seeds were inoculated into Murashige and Skoog (MS) liquid medium supplemented with 4 µM α-naphthaleneacetic acid (NAA) to induce NCs and in culture medium without plant growth regulators to form normal seedlings. Samples collected at 0, 3, 7, 10, 14, and 21 days of culture were analyzed. All parameters assessed showed the same variation pattern. However, seeds inducing NCs showed significantly lower starch (6.0 mg g-1 FM), carbohydrate (10.7 mg g-1 FM) and GDM (11.0%)...
