1. Yeast extract elicitation increases vinblastine and vincristine yield in protoplast derived tissues and plantlets in Catharanthus roseus
Abstract Catharanthus roseus (L.) G. Don, Apocynaceae, is an immensely important medicinal plant, produces a variety of anticancerous compounds. The yield of two most investigated alkaloids vinblastine and vincristine is unfortunately very low. A vast array of technologies including elicitation have recently been used to enrich Catharanthus alkaloid in cultu

2. Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism
ABSTRACT In recent years, the use of biostimulants in sustainable agriculture has been growing. Biostimulants can be obtained from different organic materials and include humic substances (HS), complex organic materials, beneficial chemical elements, peptides and amino acids, inorganic salts, seaweed extracts, chitin and chitosan derivatives, antitranspirant

3. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.

4. Resistência à ferrugem do cafeeiro: mapeamento genético, físico e análise da expressão gênica em resposta a infecção de H. vastatrix / Coffea leaf rust: genetic, physical mapping and analysis of the gene expression in response to infection the H. vastatrix
The coffee leaf rust it is caused by the biothrofic fungus Hemileia vastatrix is one diseases that more it causes economical damages. The coffee breeding for obtaining for resistance plants it is slow and the moleculars studies of identification for resistance genes to H. vastatrix are still few informative. This study had as objective to obtain information

5. Envolvimento dos quatro genes bZIPs do Grupo C de Arabidopsis thaliana na sinalização por glicose, manose e ABA / Functional analysis of the Arabidopsis Group C bZIPs homologous to the maize Opaque-2 regulator
In the model eudicot organism A. thaliana (Arabidopsis), four genes encoding bZIP transcription regulatory factors that are homologous to the maize Opaque-2 (O2) locus were identified. O2 is a key regulator of the carbon to nitrogen balance and of the prolamine type storage proteins synthesis during seed development. The Arabidopsis genes, AtbZIP9, the two p

6. Sinalização por carboidratos em cana-de-açucar e divergencia evolutiva / Sugar signaling in sugarcane and evolution diversification
Besides act as carbon primary source in the major types of cells, sugars produced by photosynthesis acquired important functions in the course of plant s evolution like controlling growth, development, and metabolism and acting in resistance to abiotic and biotic stresses like osmotic, energetic and response to pathogens. Sugars can be signals that active si

7. Hormonal and nitric oxide signalling in the induction of the Crassulacean acid metabolismo in Ananas comosus / Sinalização hormonal e do óxido nítrico na indução do metabolismo ácido crassuláceo em Ananas comosus
A expressão do metabolismo ácido crassuláceo (CAM) nas plantas C3-CAM facultativas pode ser fortemente modulada por uma variedade de sinais ambientais e endógenos. Visto que plantas de abacaxizeiro (Ananas comosus, variedade Smooth Cayenne) podem apresentar comportamento fotossintético do tipo C3 ou CAM quando cultivadas in vitro, o presente trabalho bu

8. Sinalização no ganho de competência para a conversão de meristemas apicais radiculares de Catasetum fimbriatum em gemas caulinares / Signalling events in the competence acquisition to root apical meristem conversion of Catasetum fimbriatum into buds.
Durante esse trabalho de pesquisa verificou-se que a aquisição de competência para conversão de ápices radiculares de Catasetum fimbriatum em gemas caulinares aumentava à medida que as plantas envelheciam. Esse processo esteve relacionado ao estabelecimento do crescimento determinado das raízes e com a parada da atividade e re-organização estrutural

9. Expression of the Arabidopsis jasmonate signalling repressor JAZ1/TIFY10A is stimulated by auxin
Plant hormones have pivotal roles in almost every aspect of plant development. Over the past decades, physiological and genetic studies have revealed that hormone action in plants is determined by complex interactions between hormonal signalling pathways. Evidence is accumulating for the existence of crosstalk between the auxin and jasmonate (JA) signalling

11. The response regulator 2 mediates ethylene signalling and hormone signal integration in Arabidopsis
Hormones are important regulators of plant growth and development. In Arabidopsis, perception of the phytohormones ethylene and cytokinin is accomplished by a family of sensor histidine kinases including ethylene-resistant (ETR) 1 and cytokinin-response (CRE) 1. We identified the Arabidopsis response regulator 2 (ARR2) as a signalling component functioning d

12. Receptor quality control in the endoplasmic reticulum for plant innate immunity
Pattern recognition receptors in eukaryotes initiate defence responses on detection of microbe-associated molecular patterns shared by many microbe species. The Leu-rich repeat receptor-like kinases FLS2 and EFR recognize the bacterial epitopes flg22 and elf18, derived from flagellin and elongation factor-Tu, respectively. We describe Arabidopsis ‘priority
