Efeito do Estresse Térmico Agudo sobre os Níveis da Proteína e RNA Mensageiro d...
Dionello, Nelson José Laurino; Ferro, Jesus Aparecido; Macari, Marcos [UNESP]; Rutz, Fernando; Furlan, Luiz Roberto [UNESP]Made available in DSpace on 2022-04-28T19:56:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2001-09-01; Eighty broiler chicks, Naked neck (Na/na) and Hubbard-Pettersen strains, were exposed to acute heat stress (36-37°C), from 2 to 5 days of age, and body weight and cloacal temperature were measured in the beginning and at the end of the heat stress period (5 h). Birds were sacrificed at the end and liver...
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...
The complete genome sequence of Chromobacterium violaceum reveals remarkable an...
Vasconcelos, Ana Tereza; De-Almeida, Darcy Fontoura; Hungría, Mariangela; Guimarães, Cláudia Teixeira; Antônio, Regina VasconcellosChromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spre...
Origin and diversification of Xanthomonas citri subsp. citri pathotypes reveale...
Patané, José Salvatore Leister; Martins Junior, Joaquim; Rangel, Luiz Thiberio; Belasque Junior, José; Digiampietri, Luciano AntonioXanthomonas citri subsp. citri pathotypes cause bacterial citrus canker, being responsible for severe agricultural losses worldwide. The A pathotype has a broad host spectrum, while A* and Aw are more restricted both in hosts and in geography. Two previous phylogenomic studies led to contrasting well-supported clades for sequenced genomes of these pathotypes. No extensive biogeographical or divergence dating an...
Serratia liquefaciens FG3 isolated from a metallophyte plant sheds light on the...
Caneschi, Washington Luiz; Sanchez, Angelica Bianchini; Felestrino, Érica Barbosa; Lemes, Camila Gracyelle de Carvalho; Cordeiro, Isabella FerreiraSerratia liquefaciens strain FG3 (SlFG3), isolated from the flower of Stachytarpheta glabra in the Brazilian ferruginous fields, has distinctive genomic, adaptive, and biotechnological potential. Herein, using a combination of genomics and molecular approaches, we unlocked the evolution of the adaptive traits acquired by S1FG3, which exhibits the second largest chromosome containing the largest conjugative plas...
Detection and identification of Xanthomonas pathotypes associated with citrus d...
Fonseca, Natasha Peixoto; Felestrino, Érica Barbosa; Caneschi, Washington Luiz; Sanchez, Angelica Bianchini; Cordeiro, Isabella FerreiraBackground. In Citrus cultures, three species of Xanthomonas are known to cause distinct diseases. X. citri subsp. citri patothype A, X. fuscans subsp. aurantifolii pathotypes B and C, and X. alfalfae subsp. citrumelonis, are the causative agents of cancrosis A, B, C, and citrus bacterial spots, respectively. Although these species exhibit different levels of virulence and aggressiveness, only limited alternati...
Gene expression analysis identifies hypothetical genes that may be critical dur...
Laia, Marcelo Luiz de; Moreira, Leandro Marcio; Gonçalves, Janaína Fernandes; Ferro, Maria Inês Tiraboschi; Rodrigues, Any Caroliny PintoBackground: Gene expression analysis via microarray is widely used in phytobacteria to validate differential gene expression associated with virulence or to compare biological profiles of wild type and mutant strains. Here, we employed DNA microarrays to study the early stages of the infection process (24, 72 and 120 h post-inoculation) of Xanthomonas citri subsp. citri (Xac) infecting Citrus sinensis to interr...
Structure and genetic relationships between Brazilian naturalized and exotic pu...
Oliveira, Joelliton Domingos de; Igarashi, Maria Luiza Silveira de Paiva; Machado, Théa Mírian Medeiros; Miretti, Marcos Mateo; Ferro, Jesus AparecidoThe genetic relationships and structure of fourteen goat (Capra hircus) populations were estimated based on genotyping data from 14 goat populations (n = 410 goats) at 13 microsatellite loci. We used analysis of molecular variance (AMOVA), principal component analysis (PCA) and F statistics (FIS, FIT and FST) to evaluate the genetic diversity (Ho, He and ad) of the goats. Genetic distances between the 14 goat p...
Proteomics-based identification of differentially abundant proteins reveals ada...
Moreira, Leandro Marcio; Silva, Marcia Regina Soares da; Facincani, Agda Paula; Ferreira, Cristiano Barbalho; Ferreira, Rafael MariniBackground: Xanthomonas citri subsp. citri (Xac) is the causal agent of citrus canker. A proteomic analysis under in planta infectious and non-infectious conditions was conducted in order to increase our knowledge about the adaptive process of Xac during infection. Results: For that, a 2D–based proteomic analysis of Xac at 1, 3 and 5 days after inoculation, in comparison to Xac growth in NB media was carried ou...
Resistência à síndrome ascítica, competência homeotérmica e níveis de Hsp70 no ...
Hernandes, Renata; Ferro, Jesus Aparecido; Gonzales, Elisabeth; Macari, Marcos; Bernal, Francisco Ernesto Moreno; Ferro, Maria Inês TiraboschiComo em outros seres vivos, também nas células das aves ocorre a síntese das proteínas de baixo peso molecular (Hsp), cujo aumento é induzido sob condições de estresse. As Hsps têm um papel importante na manutenção da integridade celular, questiona-se o seu envolvimento no mecanismo de proteção celular de órgãos alvos na ocorrência da síndrome ascítica (SA). Este trabalho objetivou avaliar a temperatura corpora...
