Journal ArticleDOI
Induced over-expression of AtDREB2A CA improves drought tolerance in sugarcane
Rafaela Ribeiro Reis,Bárbara Andrade Dias Brito da Cunha,Polyana Kelly Martins,Maria Thereza Bazzo Martins,Jean Carlos Alekcevetch,Antonio Chalfun-Junior,Alan Carvalho Andrade,Ana Paula Ribeiro,Feng Qin,Junya Mizoi,Kazuko Yamaguchi-Shinozaki,Kazuo Nakashima,J. F. C. Carvalho,Carlos Antônio Ferreira de Sousa,Alexandre Lima Nepomuceno,Adilson Kenji Kobayashi,Hugo Bruno Correa Molinari +16 more
TL;DR: Induced expression of AtDREB2A CA in sugarcane enhanced its drought tolerance without biomass penalty and led to the up-regulation of genes involved in plant response to drought stress.
Journal ArticleDOI
Candidatus Liberibacter americanus induces significant reprogramming of the transcriptome of the susceptible citrus genotype
Valéria Mafra,Polyana Kelly Martins,Carolina Sardinha Francisco,Marcelo Ribeiro-Alves,Juliana Freitas-Astúa,Marcos Antonio Machado +5 more
TL;DR: In this article, the authors evaluated the transcriptional reprogramming of a susceptible genotype of sweet orange challenged with CaLam, using a customized 385k microarray containing approximately 32,000 unigene transcripts.
Journal ArticleDOI
Suppression of a single BAHD gene in Setaria viridis causes large, stable decreases in cell wall feruloylation and increases biomass digestibility.
Wagner Rodrigo de Souza,Polyana Kelly Martins,Jackie Freeman,Till K. Pellny,Louise V. Michaelson,Bruno Leite Sampaio,Felipe Vinecky,Ana Paula Ribeiro,Bárbara Andrade Dias Brito da Cunha,Adilson Kenji Kobayashi,Patrícia Abrão de Oliveira,Raquel Bombarda Campanha,Thályta Fraga Pacheco,Danielly Caroline Inacio Martarello,Rogério Marchiosi,Osvaldo Ferrarese-Filho,Wanderley Dantas dos Santos,Robson Tramontina,Fabio M. Squina,Danilo da Cruz Centeno,Marília Gaspar,Marcia R. Braga,Marco Aurélio Silva Tiné,John Ralph,John Ralph,Rowan A. C. Mitchell,Hugo Bruno Correa Molinari +26 more
TL;DR: The first strong evidence for a key role of the BAHD01 gene in AX feruloylation is provided and it is demonstrated that it is a promising target for improvement of grass crops for biofuel, biorefining and animal nutrition applications.
Journal ArticleDOI
Selection of reliable reference genes for RT-qPCR analysis during developmental stages and abiotic stress in Setaria viridis
Polyana Kelly Martins,Valéria Mafra,Wagner Rodrigo de Souza,Ana Paula Ribeiro,Felipe Vinecky,Marcos Fernando Basso,Bárbara Andrade Dias Brito da Cunha,Adilson Kenji Kobayashi,Hugo Bruno Correa Molinari +8 more
TL;DR: This study provides a list of reliable reference genes for transcript normalization in S. viridis in different tissues and stages of development and under abiotic stresses, which will facilitate genetic studies in this monocot model plant.
Journal ArticleDOI
Setaria viridis floral-dip: A simple and rapid Agrobacterium-mediated transformation method.
Polyana Kelly Martins,Thiago Jonas Nakayama,Thiago Jonas Nakayama,Ana Paula Ribeiro,Bárbara Andrade Dias Brito da Cunha,Alexandre Lima Nepomuceno,Frank G. Harmon,Adilson Kenji Kobayashi,Hugo Bruno Correa Molinari +8 more
TL;DR: This work demonstrates through molecular analysis and RFP expression that seeds and resulting plants from dipped inflorescences were transformed and suggests the feasibility of S. viridis floral dip transformation as a time-saving and cost-effective compared with traditional methods.
