This study analysed genomic variation of the translation elongation factor 1α ( TEF‐1 α) and intergenic spacer region (IGS) nuclear ribosomal operon Fusarium oxysporum f. sp. cubense (Foc) isolates, from different banana production areas, representing strains within known races, comprising 20 vegetative compatibility groups (VCG). Based on two single nucleotide polymorphisms present in IGS region, a PCR‐based diagnostic tool was developed to specifically detect isolates VCG 01213, also...
Black Sigatoka or black leaf streak disease, caused by the Dothideomycete fungus Pseudocercospora fijiensis (previously: Mycosphaerella fijiensis), is most significant foliar disease of banana worldwide. Due to lack effective host resistance, management this requires frequent fungicide applications, which greatly increase economic and environmental costs produce banana. Weekly applications in plantations lead rapid evolution fungicide-resistant strains within populations causing...
Musa species (Zingiberaceae, Zingiberales) including bananas and plantains are collectively the fourth most important crop in developing countries. Knowledge concerning genome structure origin of distinct cultivars has greatly increased over last few years. Until now, however, no large-scale analyses genomic sequence have been conducted. This study compares two with orthologous regions rice genome. We produced 1.4 Mb from 13 BAC clones, annotated analyzed them along 4 previously sequenced...
Many commercial banana varieties lack sources of resistance to pests and diseases, as a consequence sterility narrow genetic background. Fertile wild relatives, by contrast, possess greater variability represent potential disease genes (R-genes). The largest known family plant R-genes encode proteins with nucleotide-binding site (NBS) C-terminal leucine-rich repeat (LRR) domains. Conserved motifs in such diverse species offer means for isolation candidate which may be involved defence. A...
We investigated the effects of plant growth-promoting bacteria (PGPB) on growth and nutrition coffee seedlings biological control leaf rust (Hemileia vastatrix), brown eye spot (Cercospora coffeicola), blight (Boeremia coffeae). In first part study, nineteen PGPB strains obtained in phyllosphere, endosphere rhizosphere other hosts, produced varied metabolites related to control. Two cultivars were treated with bacterial strains, but cultivar Catuaí Amarelo IAC 62 was less responsive...
As estratégias eficazes de prevenção e tratamento das doenças polimicrobianas dependem da compreensão interações entre os microrganismos hospedeiros. Os modelos animais têm sido amplamente utilizados na investigação para melhorar a medicina moderna, criar vacinas medicamentos obter uma básica origem humanas. O objetivo deste trabalho foi realizar revisão sobre o uso Galleria mellonella como modelo coinfecção microbiana destacando suas vantagens limitações. Verificou-se que mortalidade do...
The expansion of the oil palm in marginal areas can face challenges, such as water deficit, leading to an impact on production. A better understanding biological consequences abiotic stresses this crop result from joint metabolic profiling and multivariate analysis. Metabolic leaves was performed control stressed plants (7 14 days stress). Samples were extracted analyzed a UHPLC-ESI-Q-TOF-HRMS system. Acquired data processed using XCMS Online MetaboAnalyst for pathway activity Metabolism...
Photosynthesis can be roughly separated into biochemical and photochemical processes. Both are affected by drought assessed non-invasive standard methods. Gas exchange, which mainly assesses the first process, has well-defined protocols. It is considered a method for evaluation of plant responses to drought. Under such stress, assessment apparatus chlorophyll fluorescence needs improvement become faster reproducible, especially in growing plants under field conditions. For this, we developed...
The feasibility of thermography as a technique for plant screening aiming at drought-tolerance has been proven by its relationship with gas exchange, biomass, and yield. In this study, unlike most the previous, was applied phenotyping contrasting maize genotypes whose classification drought tolerance had already established in field. Our objective to determine whether thermography-based would discriminate similar way field selection which just grain yield taken into account criterion. We...
Oil palm (Elaeis guineensis Jacq.) is the number one source of consumed vegetable oil nowadays. It cultivated in areas tropical rainforest, where it meets its natural condition high rainfall throughout year. The industry faces criticism due to a series practices that was considered not environmentally sustainable, and finds itself under pressure adopt new innovative procedures reverse this negative public perception. Cultivating oilseed crop outside rainforest zone only possible using...
Oil palm (Elaeis guineensis Jacq.) is a oilseed crop of great economic importance drastically affected by abiotic stresses. MicroRNAs (miRNAs) play crucial roles in transcription and post-transcription regulation gene expression, being essential molecules the response plants to stress. To better understand molecular mechanisms behind young oil drought stress, this study reports on prediction characterization miRNAs their putative target genes apical leaf subjected 14 days water deprivation....
Banana is a nutritionally important crop across tropical and sub-tropical countries in sub-Saharan Africa, Central South America Asia. Although cultivars have evolved from diploid, triploid tetraploid wild Asian species of Musa acuminata (A genome) balbisiana (B genome), many today's commercial are sterile triploids or diploids, with fruit developing via parthenocarpy. As result restricted genetic variation, improvement has been limited, resulting frequently lacking resistance to pests...
We have designed an in vitro experimental setup to study the role of sucrose sugar-mediated acclimation banana meristems using established highly proliferating meristem cultures. It is a first step toward systems biology and understanding how it can survive severe abiotic stress. Using 2D-DIGE proteomic approach meristem-specific EST library, we describe long-term response (after 2, 4, 8, 14 days) analyze this by setting up control, sorbitol, treatment over time. Sucrose synthase dominant...
Abstract Background Several mechanisms regulating gene expression contribute to restore and reestablish cellular homeostasis so that plants can adapt survive in adverse situations. MicroRNAs (miRNAs) play roles important the transcriptional post-transcriptional regulation of expression, emerging as a regulatory molecule key responses plant stress, such cold, heat, drought, salt. This work is comprehensive large-scale miRNA analysis performed characterize population present oil palm ( Elaeis...
Drought and salinity are two of the most severe abiotic stresses affecting agriculture worldwide bear some similarities regarding responses plants to them. The first is also known as osmotic stress shows mainly with effect, phase stress. Multi-Omics Integration (MOI) offers a new opportunity for non-trivial challenge unraveling mechanisms behind multigenic traits, such drought resistance. current study carried out comprehensive, large-scale, single-omics analysis (SOA) MOI studies on leaves...
The genetic complexity in the genus Musa has been subject of study many breeding programs worldwide. Parthenocarpy, female sterility, polyploidy different cultivars and limited amount genomic information make production new banana difficult time consuming. In addition, it is known that part related wild species contain numerous chromosomal rearrangements. order to produce more effectively breeders must better understand differences potential crossing parents for introgression hybridization,...
Banana (Musa acuminata) is a crop contributing to global food security. Many varieties lack resistance biotic stresses, due sterility and narrow genetic background. The objective of this study was develop an expressed sequence tag (EST) database transcripts during compatible incompatible banana-Mycosphaerella fijiensis (Mf) interactions. Black leaf streak disease (BLSD), caused by Mf, destructive banana. Microsatellite markers were developed as resource for improvement.cDNA libraries...
