Genome-wide identification, phylogeny, and gene duplication of the epigenetic r...
Alves, Sofia; Braga, Ângelo; Parreira, Denise; Alhinho, Ana Teresa; Silva, Helena Sofia Gomes; Ramos, Miguel Jesus Nunes; Costa, Maria Manuela RibeiroEpigenetic regulators are proteins involved in controlling gene expression. Information about the epigenetic regulators within the Fagaceae, a relevant family of trees and shrubs of the northern hemisphere ecosystems, is scarce. With the intent to characterize these proteins in Fagaceae, we searched for orthologs of DNA methyltransferases (DNMTs) and demethylases (DDMEs) and Histone modifiers involved in acetyl...

The dynamics of flower development in Castanea sativa Mill
Alhinho, Ana Teresa Talhinhas Barata; Ramos, Miguel Jesus Nunes; Alves, Sofia; Rocheta, Margarida; Morais-Cecílio, Leonor; Gomes-Laranjo, JoséThe sweet chestnut tree (<i>Castanea sativa</i> Mill.) is one of the most significant Mediterranean tree species, being an important natural resource for the wood and fruit industries. It is a monoecious species, presenting unisexual male catkins and bisexual catkins, with the latter having distinct male and female flowers. Despite the importance of the sweet chestnut tree, little is known regarding the molecul...

Deep analysis of wild Vitis flower transcriptome reveals unexplored genome regi...
Ramos, Miguel Jesus Nunes; Coito, João Lucas; Fino, Joana; Cunha, Jorge; Silva, Helena; Almeida, Patrícia Gomes; Costa, Maria Manuela RibeiroKey message RNA-seq of Vitis during early stages of bud development, in male, female and hermaphrodite flowers, identified new loci outside of annotated gene models, suggesting their involvement in sex establishment. Abstract The molecular mechanisms responsible for flower sex specification remain unclear for most plant species. In the case of V. vinifera ssp. vinifera, it is not fully understood what determine...
Flower development and sex specification in wild grapevine
Ramos, Miguel Jesus Nunes; Coito, João Lucas; Silva, Helena Gomes; Cunha, Jorge; Costa, Maria Manuela Ribeiro; Rocheta, MargaridaBackground: Wild plants of Vitis closely related to the cultivated grapevine (V. v. vinifera) are believed to have been first domesticated 10,000 years BC around the Caspian Sea. V. v. vinifera is hermaphrodite whereas V. v. sylvestris is a dioecious species. Male flowers show a reduced pistil without style or stigma and female flowers present reflexed stamens with infertile pollen. V. vinifera produce perfect ...
