Abstract The survival of plants, as sessile organisms, depends on a series postembryonic developmental events that determine the final architecture plants and allow them to contend with continuously changing environment. Modulation cell differentiation organ formation by environmental signals has not been studied in detail. Here, we report alterations pattern lateral root (LR) emergence response phosphate (Pi) availability is mediated changes auxin sensitivity Arabidopsis thaliana roots....
Polar bears (PBs) are superbly adapted to the extreme Arctic environment and have become emblematic of threat biodiversity from global climate change. Their divergence lower-latitude brown bear provides a textbook example rapid evolution distinct phenotypes. However, limited mitochondrial nuclear DNA evidence conflicts in timing PB origin as well placement species within versus sister lineage. We gathered extensive genomic sequence data contemporary polar, brown, American black samples,...
It has been argued that the evolution of plant genome size is principally unidirectional and increasing owing to varied action whole-genome duplications (WGDs) mobile element proliferation. However, extreme reductions have reported in angiosperm family tree. Here we report sequence 82-megabase carnivorous bladderwort Utricularia gibba. Despite its tiny size, U. gibba accommodates a typical number genes for plant, with main difference from other genomes arising drastic reduction non-genic...
The avocado, Persea americana, is a fruit crop of immense importance to Mexican agriculture with an increasing demand worldwide. Avocado lies in the anciently diverged magnoliid clade angiosperms, which has controversial phylogenetic position relative eudicots and monocots. We sequenced nuclear genomes avocado race, P. americana var. drymifolia, most commercially popular hybrid cultivar, Hass, anchored latter chromosomes using genetic map. Resequencing Guatemalan West Indian varieties...
Background Drought is one of the major constraints for plant productivity worldwide. Different mechanisms drought-tolerance have been reported several species including maize. However, differences in global gene expression between drought-tolerant and susceptible genotypes their relationship to physiological adaptations drought are largely unknown. The study tolerant could provide important information design more efficient breeding programs produce maize varieties better adapted water...
Nuclear Factor Y (NF-Y) is a heterotrimeric complex formed by NF-YA/NF-YB/NF-YC subunits that binds to the CCAAT-box in eukaryotic promoters. In contrast other organisms, which single gene encodes each subunit, plants families of over 10 members encode subunits. Here we report five Arabidopsis thaliana NF-YA family are strongly induced several stress conditions via transcriptional and miR169-related post-transcriptional mechanisms. Overexpression NF-YA2, 7 resulted dwarf late-senescent with...
Background Animal-derived elicitors can be used by plants to detect herbivory but they function only in specific insect–plant interactions. How generally perceive damage caused herbivores? Damaged-self recognition occurs when molecular signals of damage: degraded plant molecules or localized outside their original compartment. Methodology/Principal Findings Flame wounding applying leaf extract solutions sucrose ATP slightly wounded lima bean (Phaseolus lunatus) leaves induced the secretion...
A high-throughput sequencing approach was utilized to carry out a comparative transcriptome analysis of Trichoderma atroviride IMI206040 during mycoparasitic interactions with the plant-pathogenic fungus Rhizoctonia solani. In this study, transcript fragments 7,797 genes were sequenced, 175 which host responsive. According functional annotation these by KOG (eukaryotic orthologous groups), most abundant group direct contact "metabolism." Quantitative reverse transcription (RT)-PCR confirmed...
Utricularia gibba, the humped bladderwort, is a carnivorous plant that retains tiny nuclear genome despite at least two rounds of whole duplication (WGD) since common ancestry with grapevine and other species. We used third-generation assembly several complete chromosomes to reconstruct most recent lineage-specific ancestral genomes led modern U. gibba structure. Patterns subgenome dominance in WGD, both architectural transcriptional, are suggestive allopolyploidization, which may have...
Maize (Zea mays) is the most widely cultivated crop around world; however, it commonly affected by phosphate (Pi) deficiency in many regions, particularly acid and alkaline soils of developing countries. To cope with Pi deficiency, plants have evolved a large number developmental biochemical adaptations; for maize, underlying molecular basis these responses still unknown. In this work, transcriptional response maize roots to starvation at 1, 3, 6, 10 d after onset deprivation was assessed....
The mechanism by which plants synthesize and store high amounts of triacylglycerols (TAG) in tissues other than seeds is not well understood. comprehension controls for carbon partitioning oil accumulation nonseed essential to generate oil-rich biomass perennial bioenergy crops. Persea americana (avocado), a basal angiosperm with unique features that are ancestral most flowering plants, stores ~ 70 % TAG per dry weight its mesocarp, tissue. Transcriptome analyses select pathways, from...
Abstract Background Geminiviruses are a large and important family of plant viruses that infect wide range crops throughout the world. The Begomovirus genus contains species transmitted by whiteflies distributed worldwide causing disease on an array horticultural crops. Symptom remission, in which newly developed leaves systemically infected plants exhibit reduction symptom severity (recovery), has been observed pepper ( Capsicum annuum ) with Pepper golden mosaic virus (PepGMV). Previous...
Dung beetles are holometabolous insects that feed on herbivorous mammal dung and provide services to the ecosystem including nutrient cycling soil fertilization. It has been suggested organisms developing incomplete diets such as dungs require association with microorganisms for synthesis utilization of nutrients. We describe diversity composition gut-microbiota during life cycle beetle Copris incertus using 16S rRNA gene sequencing. found C. gut contained a broad bacterial groups (1,699...
Copper nanoparticles (Cu-NPs) have shown great antifungal activity against phytopathogenic fungi, making them a promising and affordable alternative to conventional fungicides. In this study, we evaluated the of Cu-NPs Fusarium kuroshium, causal agent dieback, might be first study do so. The (at different concentrations) inhibited more than 80% F. kuroshium growth were even efficient commercial fungicide used as positive control (cupric hydroxide). Electron microscopy studies revealed...

Alkamides are fatty acid amides of wide distribution in plants, structurally related to N-acyl-L-homoserine lactones (AHLs) from Gram-negative bacteria and N- acylethanolamines (NAEs) plants mammals. Global analysis gene expression changes Arabidopsis thaliana response N-isobutyl decanamide, the most highly active alkamide identified date, revealed an overrepresentation defense-responsive transcriptional networks. In particular, genes encoding enzymes for jasmonic (JA) biosynthesis increased...
Abstract Background In-depth sequencing analysis has not been able to determine the overall complexity of transcriptional activity a plant organ or tissue sample. In some cases, deep parallel Expressed Sequence Tags (ESTs), although yet optimized for cDNAs, represented an efficient procedure validating gene prediction and estimating coverage. This approach could be very valuable complex genomes. addition, little emphasis given efforts aiming at estimation universe found in multicellular...
Plants are exposed to several biotic and abiotic stresses. A common environmental stress that plants have face both in natural agricultural ecosystems impacts its growth development is low phosphate (Pi) availability. There has been an important progress the knowledge of molecular mechanisms by which cope with Pi deficiency. However, mediate alterations architecture Arabidopsis root system responses starvation still largely unknown. One most conspicuous developmental effects on inhibition...
