Thus, they have to face hazards with instantaneous reorganization of their internal environment. For this purpose, besides the use of transcription factors, the participation of chromatin as an active factor in the regulation of transcription is crucial. Chemical changes in chromatin structure affect the accessibility of the transcriptional machinery and acting in signaling, engaging/inhibiting factors that participate in the transcription processes. Mechanisms in which gene expression undergoes changes without the occurrence of DNA gene mutations in the monomers that make up DNA, are understood as epigenetic phenomena. These include (1) post-translational modifications of histones, which results in stimulation or repression of gene activity and (2) cytosine methylation in the promoter region of individual genes, both preventing access of transcriptional activators as well as signaling the recruitment of repressors. There is evidence that such modifications can pass on to subsequent generations of daughter cells and even generations of individuals. However, reports indicate that they persist only in the presence of a stressor factor (or an inductor of the above-mentioned modifications). In its absence, these modifications weaken or lose heritability, being eliminated in the next few generations. In this review, it is argued how epigenetic signals influence gene regulation, the mechanisms involved and their participation in processes of resistance to biotic stresses, controlling processes of the plant immune system.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27455972?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Wanderley-Nogueira, Ana Carolina</style></author><author><style face="normal" font="default" size="100%">Bezerra-Neto, João Pacífico</style></author><author><style face="normal" font="default" size="100%">Kido, Éderson Akio</style></author><author><style face="normal" font="default" size="100%">de Araújo, Flávia Tadeu</style></author><author><style face="normal" font="default" size="100%">Amorim, Lidiane Lindinalva Barbosa</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Benko-Iseppon, Ana Maria</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Plant Elite Squad: First Defense Line and Resistance Genes - Identification, Diversity and Functional Roles.</style></title><secondary-title><style face="normal" font="default" size="100%">Curr Protein Pept Sci</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Curr.

A crucial step to define the fate of the plant facing an invading pathogen is the activation of a compatible Resistance (R) gene, the focus of the present review. Different aspects regarding R-genes and their products are discussed, including pathogen recognition mechanisms, signaling and effects on induced and constitutive defense processes, splicing and post transcriptional mechanisms involved. There are still countless challenges to the complete understanding of the mechanisms involving R-genes in plants, in particular those related to the interactions with other genes of the pathogen and of the host itself, their regulation, acting mechanisms at transcriptional and post-transcriptional levels, as well as the influence of other types of stress over their regulation. A magnification of knowledge is expected when considering the novel information from the omics and systems biology.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27455974?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Maria, Ana Carolina Wanderley-Nogueira</style></author><author><style face="normal" font="default" size="100%">Bezerra-Neto, João Pacífico</style></author><author><style face="normal" font="default" size="100%">Kido, Éderson Akio</style></author><author><style face="normal" font="default" size="100%">de Araújo, Flávia Tadeu</style></author><author><style face="normal" font="default" size="100%">Amorim, Lidiane Lindinalva Barbosa</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Benko-Iseppon, Ana Maria</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Plants Defense-related Cyclic Peptides: Diversity, Structure and Applications.</style></title><secondary-title><style face="normal" font="default" size="100%">Curr Protein Pept Sci</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Curr.

Aiming at defending themselves, plants have developed several strategies to survive and adapt to such adversities. Cyclotides are a family of plant-derived proteins that exhibit a diverse range of biological activities including antimicrobial and insecticidal activities that actively participate in plant defense processes. Three main categories of peptides have been described: (i) Cyclotides (ii) Sunflower Trypsin Inhibitor (SFTI) and (iii) peptides MCoTI-I and II, from Momordica cochinchinensis. They comprise proteins of approximately 30 amino acids, containing a head-to-tail cyclized backbone, with three disulfide bonds configured in a cystine knot topology, therefore bearing greater peptide stability. Given their features and multifunctionality, cyclotides stand out as promising sources for the discovery of new antimicrobial agents. The present review describes cyclotide occurrence, abundance and action in plants, also their diversity and evolution. Considerations regarding their use in the context of biomedical and agronomical sciences uses are also presented.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27455973?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pandolfi, Valesca</style></author><author><style face="normal" font="default" size="100%">Neto, José Ribamar Costa Ferreira</style></author><author><style face="normal" font="default" size="100%">Silva, Manassés Daniel</style></author><author><style face="normal" font="default" size="100%">Amorim, Lidiane Lindinalva Barbosa</style></author><author><style face="normal" font="default" size="100%">Wanderley-Nogueira, Ana Carolina</style></author><author><style face="normal" font="default" size="100%">de Oliveira Silva, Roberta Lane</style></author><author><style face="normal" font="default" size="100%">Kido, Éderson Akio</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Iseppon, Ana Maria Benko</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Resistance (R) Genes: Applications and Prospects for Plant Biotechnology and Breeding.</style></title><secondary-title><style face="normal" font="default" size="100%">Curr Protein Pept Sci</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Curr.

However, due to environmental pressure and high selection operated by pathogens, several crop plants have lost specificity, broad-spectrum or durability of resistance. On the other hand, the advances in plant genome sequencing and biotechnological approaches, combined with the increasing knowledge on R-genes have provided new insights on their applications for plant genetic breeding, allowing the identification and implementation of novel and efficient strategies that enhance or optimize their use for efficiently controlling plant diseases. The present review focuses on main perspectives of application of R-genes and its co-players for the acquisition of resistance to pathogens in cultivated plants, with emphasis on biotechnological inferences, including transgenesis, cisgenesis, directed mutagenesis and gene editing, with examples of success and challenges to be faced.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27455971?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Oliveira-Lima, Marx</style></author><author><style face="normal" font="default" size="100%">Benko-Iseppon, Ana Maria</style></author><author><style face="normal" font="default" size="100%">Neto, José Ribamar Costa Ferreira</style></author><author><style face="normal" font="default" size="100%">Rodríguez-Decuadro, Susana</style></author><author><style face="normal" font="default" size="100%">Kido, Éderson Akio</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Pandolfi, Valesca</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Snakin: Structure, Roles and Applications of a Plant Antimicrobial Peptide.</style></title><secondary-title><style face="normal" font="default" size="100%">Curr Protein Pept Sci</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Curr.

These peptides are known to play different roles in response to a variety of biotic (i.e. induced by bacteria, fungi and nematode pathogens) and abiotic (salinity, drought and ROS) stressors, as well as in crosstalk promoted by plant hormones, with emphasis on abscisic and salicylic acid (ABA and SA, respectively). Such properties make snakin/GASA members promising biotechnological sources for potential therapeutic and agricultural applications. However, information regarding their tertiary structure, mode of action and function are not yet completely elucidated. The present review presents aspects of snakin structure, expression, functional studies and perspectives about the potential applications for agricultural and medical purposes.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/27323806?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kido, Éderson Akio</style></author><author><style face="normal" font="default" size="100%">Ferreira Neto, José Ribamar Costa</style></author><author><style face="normal" font="default" size="100%">Silva, Roberta Lane de Oliveira</style></author><author><style face="normal" font="default" size="100%">Pandolfi, Valesca</style></author><author><style face="normal" font="default" size="100%">Guimarães, Ana Carolina Ribeiro</style></author><author><style face="normal" font="default" size="100%">Veiga, Daniela Truffi</style></author><author><style face="normal" font="default" size="100%">Chabregas, Sabrina Moutinho</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Benko-Iseppon, Ana Maria</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">New insights in the sugarcane transcriptome responding to drought stress as revealed by superSAGE.</style></title><secondary-title><style face="normal" font="default" size="100%">ScientificWorldJournal</style></secondary-title><alt-title><style face="normal" font="default" size="100%">ScientificWorldJournal</style></alt-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Droughts</style></keyword><keyword><style  face="normal" font="default" size="100%">Gene Expression Profiling</style></keyword><keyword><style  face="normal" font="default" size="100%">Heat-Shock Response</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Proteins</style></keyword><keyword><style  face="normal" font="default" size="100%">Saccharum</style></keyword><keyword><style  face="normal" font="default" size="100%">Transcriptome</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">2012</style></volume><pages><style face="normal" font="default" size="100%">821062</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;In the scope of the present work, four SuperSAGE libraries have been generated, using bulked root tissues from four drought-tolerant accessions as compared with four bulked sensitive genotypes, aiming to generate a panel of differentially expressed stress-responsive genes. Both groups were submitted to 24 hours of water deficit stress. The SuperSAGE libraries produced 8,787,315 tags (26 bp) that, after exclusion of singlets, allowed the identification of 205,975 unitags. Most relevant BlastN matches comprised 567,420 tags, regarding 75,404 unitags with 164,860 different ESTs. To optimize the annotation efficiency, the Gene Ontology (GO) categorization was carried out for 186,191 ESTs (BlastN against Uniprot-SwissProt), permitting the categorization of 118,208 ESTs (63.5%). In an attempt to elect a group of the best tags to be validated by RTqPCR, the GO categorization of the tag-related ESTs allowed the in silico identification of 213 upregulated unitags responding basically to abiotic stresses, from which 145 presented no hits after BlastN analysis, probably concerning new genes still uncovered in previous studies. The present report analyzes the sugarcane transcriptome under drought stress, using a combination of high-throughput transcriptome profiling by SuperSAGE with the Solexa sequencing technology, allowing the identification of potential target genes during the stress response.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/22629208?dopt=Abstract</style></custom1></record></records></xml>
