1. Gene da família Arabidopsis CK2 CKB3 envolvido na sinalização de ácido abscísico
Resumo CKB3 é uma subunidade reguladora (beta) de CK2. Neste estudo, o mutante homozigoto ckb3 de Arabidopsis thaliana foi estudado para entender o papel da CKB3 na sinalização de ácido abscísico (ABA). Os resultados apresentados: CKB3 foi expresso em todos os órgãos e a maior expressão nas sementes, seguida pela raiz. Durante a germinação das seme

2. Ammopiptanthus mongolicus stress-responsive NAC gene enhances the tolerance of transgenic Arabidopsis thaliana to drought and cold stresses
Abstract Drought and cold are the primary factors limiting plant growth worldwide. The Ammopiptanthus mongolicus NAC11 (AmNAC11) gene encodes a stress-responsive transcription factor. Expression of the AmNAC11 gene was induced by drought, cold and high salinity. The AmNAC11 protein was localized in the nucleus and plays an important role in tolerance to drou

3. Network analysis of ABA-dependent and ABA-independent drought responsive genes in Arabidopsis thaliana
Abstract Drought is one of the most severe abiotic factors restricting plant growth and yield. Numerous genes functioning in drought response are regulated by abscisic acid (ABA) dependent and independent pathways, but knowledge of interplay between the two pathways is still limited. Here, we integrated transcriptome sequencing and network analyses to explor

4. Expression analysis of cell wall assembly and remodelling-related genes in Arabidopsis roots subjected to boron stress and brassinosteroid at different developmental stages
ABSTRACT Plant cell walls are affected by many biotic and abiotic stress conditions. The aim of this study is to determine the effects of 24-Epibrassinolide (EBL) on some cell wall-related genes in root tissue of five- and ten-week-old Arabidopsis thaliana plants exposed to boron (B) deficiency (0 µM) or toxicity (3000 µM) at the transcriptional level.

5. Expression analysis of the Arabidopsis thaliana AtSpen2 gene, and its relationship with other plant genes encoding Spen proteins
Abstract Proteins of the Split ends (Spen) family are characterized by an N-terminal domain, with one or more RNA recognition motifs and a SPOC domain. In Arabidopsis thaliana, the Spen protein FPA is involved in the control of flowering time as a component of an autonomous pathway independent of photoperiod. The A. thaliana genome encodes another gene for a

6. PROMOTORES DE FLOEMA SÃO DIFERENTEMENTE ATIVADOS POR Candidatus Liberibacter asiaticus EM LARANJEIRAS DOCES TRANSGÊNICAS
RESUMO A utilização de promotores preferencialmente expressos em tecidos vegetais específicos é uma estratégia desejável na busca por resistência a patógenos que colonizam tais tecidos. A bacteria Candidatus Liberibacter asiaticus (Las), associada à doença huanglongbing (HLB) em citros, coloniza o tecido floemático. Alguns promotores, além de co

7. Arabidopsis thaliana as a model host for Brevipalpus mite-transmitted viruses
ABSTRACT: Brevipalpus-transmitted viruses (BTV) are a taxonomically diverse group of plant viruses which severely affect a number of major crops. Members of the group can be sub-classified into cytoplasmic (BTV-C) or nuclear type (BTV-N) according to the accumulation sites of virions in the infected plant cells. Both types of BTV produce only local infection

hrpZ gene fromPseudomonas syringae pv.maculicola M2Pseudomonas syringae pv.maculicola is a natural pathogen of members of the Brassicaceae plant family. Using a transposon-based mutagenesis strategy inPseudomonas syringae pv.maculicola M2 (PsmM2), we conducted a genetic screen to identify mutants that were capable of growing in M9 mediuBraz. J.

10. Introduction of the rd29A: AtDREB2A CA gene into soybean (Glycine max L. Merril) and its molecular characterization in leaves and roots during dehydration
The loss of soybean yield to Brazilian producers because of a water deficit in the 2011-2012 season was 12.9%. To reduce such losses, molecular biology techniques, including plant transformation, can be used to insert genes of interest into conventional soybean cultivars to produce lines that are more tolerant to drought. The abscisic acid (ABA)-independent

11. Estudos iniciais de caracterização funcional de peroxidases e laccases potencialmente envolvidas no processo de lignificação em cana-de-açúcar / Initial studies on the functional characterization of peroxidases and laccases potentially involved in the lignification process in sugarcane
Lignin is a complex heteropolymer deposited in the secondarily thickened walls of specialized plant cells to provide strength and rigidity for plants to stand upright and hydrophobicity to conducting cells for long-distance water transport. Although lignin is essential for plant growth and development, this phenolic polymer is the major plant cell wall compo

12. O fator de transcrição AtbZIP63 como integrador de sinais energéticos e estresses biótico/abiótico / The transcription factor AtbZIP63 as a integrator of energetic signals and biotic/abiotic stresses
A manutenção do balanço energético em plantas é de crucial importância para a otimização de seu crescimento e desenvolvimento em resposta às condições sempre flutuantes do meio. A energia obtida através da fotossíntese deve ser utilizada parcimoniosamente e dividida entre crescimento, desenvolvimento, armazenamento e respostas a estresses bióti
