Editorial: Molecular Mechanisms of Flowering Plant Reproduction
Pabón-Mora, Natalia; Goldman, Maria Helena S.; Smyth, David R.; Muschietti, Jorge; Costa, Maria Manuela Ribeiro[Excerpt] Introduction: Plant reproduction is an intricate process important for the survival of all dominant autotrophs and critical in agriculture and stable food production as the basis of our diet. Angiosperms undergo extreme transformations during their ontogeny, leading to the reproductive transition. During this process, several steps are needed, including transforming a shoot apical or a lateral vegetat...
SCI1 Is a Direct Target of AGAMOUS and WUSCHEL and Is Specifically Expressed in...
Cruz, Joelma O.; San Martin, Juca A.B.; Lubini, Greice; Strini, Edward J.; Sobral, Rómulo Sacramento; Pinoti, Vitor F.; Ferreira, Pedro B.The specified floral meristem will develop a pre-established number of floral organs and, thus, terminate the floral meristematic cells. The floral meristematic pool of cells is controlled, among some others, by WUSCHEL (WUS) and AGAMOUS (AG) transcription factors (TFs). Here, we demonstrate that the SCI1 (Stigma/style cell-cycle inhibitor 1) gene, a cell proliferation regulator, starts to be expressed since th...
The Genome of Anopheles darlingi, the main neotropical malaria vector
Marinotti, Osvaldo; Cerqueira, Gustavo C.; Almeida, Luiz G.P.; Ferro, Maria Inês Tiraboschi; Loreto, Elgion Lúcio da Silva; Zaha, ArnaldoAnopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and f...

No. of bitstreams: 0 Previous issue date: 2019-02-13; National Institute of Agrobiological Sciences; A sugarcane gene encoding a dirigent-jacalin, ShDJ, was induced under drought stress. To elucidate its biological function, we integrated a ShDJ-overexpression construction into the rice Nipponbare genome via Agrobacterium-mediated transformation. Two trans...

Functional characterization of a xylose transporter in Aspergillus nidulans
Rodrigues, Fernando José dos Santos; Menino, João F.; Colabardini, Ana Cristina; Ries, Laure Nicolas Annick; Brown, Neil AndrewBACKGROUND: The production of bioethanol from lignocellulosic feedstocks will only become economically feasible when the majority of cellulosic and hemicellulosic biopolymers can be efficiently converted into bioethanol. The main component of cellulose is glucose, whereas hemicelluloses mainly consist of pentose sugars such as D-xylose and L-arabinose. The genomes of filamentous fungi such as A. nidulans encode...
Identification of metabolic pathways influenced by the G-protein coupled recept...
Souza, Wagner R. de; Morais, Enyara Rezende; Krohn, Nadia Graciele; Savoldi, Marcela; Goldman, Maria Helena S.; Rodrigues, Fernando; Caldana, CamilaHeterotrimeric G-protein-mediated signaling pathways play a pivotal role in transmembrane signaling in eukaryotes. Our main aim was to identify signaling pathways regulated by A. nidulans GprB and GprD G-protein coupled receptors (GPCRs). When these two null mutant strains were compared to the wild-type strain, the DeltagprB mutant showed an increased protein kinase A (PKA) activity while growing in glucose 1% ...
Identification of glucose transporters in Aspergillus nidulans
Reis, Thaila Fernanda dos; Menino, João F.; Pedro Bom, Vinícius Leite; Brown, Neil Andrew; Colabardini, Ana Cristina; Savoldi, Marcelao characterize the mechanisms involved in glucose transport, in the filamentous fungus Aspergillus nidulans, we have identified four glucose transporter encoding genes hxtB-E. We evaluated the ability of hxtB-E to functionally complement the Saccharomyces cerevisiae EBY.VW4000 strain that is unable to grow on glucose, fructose, mannose or galactose as single carbon source. In S. cerevisiae HxtB-E were targeted ...
The conserved and divergent roles of carbonic anhydrases in the filamentous fun...
Han, Kap-Hoon; Chun, Yoon-Hee; Figueiredo, Bárbara de Castro Pimentel; Soriani, Frederico Marianetti; Savoldi, Marcela; Almeida, Agostinho João RamalhoCarbon dioxide (CO(2)) and its hydration product bicarbonate (HCO(3)(-)) are essential molecules in various physiological processes of all living organisms. The reversible interconversion between CO(2) and HCO(3)(-) is in equilibrium. This reaction is slow without catalyst, but can be rapidly facilitated by Zn(2+)-metalloenzymes named carbonic anhydrases (CAs). To gain an insight into the function of multiple c...
