1. Effects of Citrus Sudden Death Disease on Fatty Acid Profile of Orange Tree Bark
Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showe

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. Advances in induced resistance by natural compounds: towards new options for woody crop protection
ABSTRACT: The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that re

5. Elicitation Enhanced the Production of Phenolic Compounds and Biological Activities in Hairy Root Cultures of Bitter melon ( Momordica charantia L.)
ABSTRACT Momordica charantia (Cucurbitaceae) is an important vegetable and also medicinal crop which produces the bioactive compounds for various biological activities with potential uses in human health. The present investigation relates to elicitors of jasmonic acid (JA) and salicylic acid (SA) to enhance biomass accumulation and phenolic compound producti

6. Antagonistic rhizobacteria and jasmonic acid induce resistance against tomato bacterial spot
AbstractTomato bacterial spot on tomato may be caused by four species of Xanthomonas and among them X. gardneri(Xg) is the most destructive one, especially in areas irrigated using a center pivot system in Minas Gerais state and the midwest region of Brazil. Due to the ineffectiveness of chemical control and the lack of cultivars with high levels of genetic

7. Molecular characterization of the Jatropha curcas JcR1MYB1 gene encoding a putative R1-MYB transcription factor
The cDNA encoding the R1-MYB transcription factor, designated as JcR1MYB1, was isolated from Jatropha curcas using rapid amplification of cDNA ends. JcR1MYB1 contains a 951 bp open reading frame that encodes 316 amino acids. The deduced JcR1MYB1 protein was predicted to possess the conserved, 56-amino acid-long DNA-binding domain, which consists of a single

8. Induction of resistance to Pyricularia oryzae in wheat by acibenzolar-S-methyl, ethylene and jasmonic acid
This study investigated the effects of acibenzolar-S-methyl (ASM), ethylene (ET) and jasmonic acid (JA) on the resistance of two wheat cultivars (BRS-229 and BR-18) to infection by Pyricularia oryzae. The treatments included spraying plants with ASM (300 mg L-1), ET (0.5 mM), JA (0.1 mM) and distilled water (control) 48 h before inoculation with P. oryzae. M

9. Indução do promotor GmNAC6 por elicitores de estresses e mapeamento de regiões reguladoras / Induction of the promoter GmNAC6 by elicitors of stress and mapping of regulatory regions
NAC domain-containing proteins are unique to plants and comprise a large gene family of transcriptional factors implicated in diverse aspects of plant development and stress responses. The GmNAC6 was recently identified as a downstream component of the ER (endoplasmic reticulum) stress- and osmotic stress-induced NRP (N-rich proteins)-mediated cell death sig

10. Plant growth-promoting rhizobacteria (PGPR): their potential as antagonists and biocontrol agents
Bacteria that colonize plant roots and promote plant growth are referred to as plant growth-promoting rhizobacteria (PGPR). PGPR are highly diverse and in this review we focus on rhizobacteria as biocontrol agents. Their effects can occur via local antagonism to soil-borne pathogens or by induction of systemic resistance against pathogens throughout the enti

11. Jasmonic acid elicits oxidative defense and detoxification systems in Cucumis melo L. cells
This study investigated whether a jasmonic acid (JA) elicitation strategy developed in a conventional cell suspension culture could evoke melon resistance mechanisms, including secondary metabolite production. Twenty one day cultured melon cell suspensions grown in MS1 medium were supplemented with JA at the concentrations of 0.5, 5.0 and 10 µmol. Melon cul

12. Desenvolvimento de micorriza arbuscular em tomateiro (Lycopersicon esculentum cv micro-tom) insensível ao ácido jasmônico (jai1-1) e superprodutor de etileno (epinastic) / Development of arbuscular mycorrhizal in tomato (Lycopersicon esculentum cv Micro-Tom) insensitive to jasmonic acid (jai1-1) and ethylene over producer (epinastic)
Micorrizas arbusculares (MAs) são simbioses mutualistas formadas entre fungos do solo e a maioria das plantas terrestres, principalmente angiospermas. Esta simbiose pode trazer uma série de benefícios para o hospedeiro vegetal, como uma maior absorção de fosfato, um aumento na tolerância ao estresse abiótico e biótico, e resistência a agentes patog�
