Francis Martin and colleagues report genome sequences for 18 species of mycorrhizal fungi a phylogenomic analysis including 32 other fungal genomes. The study identifies cell wall-degradation genes lost in all true ectomycorrhizal and, using gene expression data, finds candidate the establishment symbiosis. To elucidate genetic bases lifestyle evolution, we sequenced new genomes, 13 (ECM), orchid (ORM) ericoid (ERM) species, five saprotrophs, which analyzed along with Ectomycorrhizal have...
ABSTRACT During fungal rock phosphate (RP) solubilization, a significant quantity of fluoride (F − ) is released together with phosphorus (P), strongly inhibiting the process. In present study, effect two F adsorbents [activated alumina (Al 2 O 3 and biochar] on RP solubilization by Aspergillus niger was examined. Al adsorbed part but also soluble P, which makes it inappropriate for microbial systems. contrast, biochar only while enhancing 3-fold, leading to accumulation up 160 mg P per...
A biotechnological strategy for the production of an alternative P fertilizer is described in this work. The was produced through rock phosphate (RP) solubilization by Aspergillus niger a solid-state fermentation (SSF) with sugarcane bagasse as substrate. SSF conditions were optimized surface response methodology after initial screening factors significant effect on RP solubilization. levels 865 mg biochar, 250 RP, 270 sucrose and 6.2 ml water per gram bagasse. At optimal setting, 8.6...
The microbiota associated with coffee plants may play a critical role in the final expression of quality. However, microbial diversity cherries is still poorly characterized. Here, we investigated endophytic Coffea arabica by using culture-independent approaches to identify microbes, ultimately better understand their ecology and potential determining Group-specific 16S rRNA 26S genes polymerase chain reaction – denaturing gradient gel electrophoresis clone library sequencing showed that...
ABSTRACT The simultaneous release of various chemical elements with inhibitory potential for phosphate solubilization from rock (RP) was studied in this work. Al, B, Ba, Ca, F, Fe, Mn, Mo, Na, Ni, Pb, Rb, Si, Sr, V, Zn, and Zr were released concomitantly P during the Araxá RP (Brazil), but only F showed effects on process at concentrations detected growth medium. Besides solubilization, fluoride decreased fungal growth, citric acid production, medium acidification by Aspergillus niger . At...
Summary Pathogenic microbes are known to manipulate the defences of their hosts through production secreted effector proteins. More recently, mutualistic mycorrhizal fungi have also been described as using these effectors promote host colonization. Here we characterize a mycorrhiza‐induced small protein 10 kDa produced by ectomycorrhizal fungus Pisolithus albus , PaMiSSP10b. We demonstrate that PaMiSSP10b is from fungal hyphae, enters cells its host, Eucalyptus grandis, and interacts with an...
Abstract The mutualistic ectomycorrhizal (ECM) fungal genus Pisolithus comprises 19 species defined to date which colonize the roots of >50 hosts worldwide suggesting that substantial genomic and functional evolution occurred during speciation. To better understand this intra-genus variation, we undertook a comparative multi-omic study nine sampled from North America, South Asia, Australasia. We found there was small core set genes common all (13%), these were more likely be...
Summary The effects of application the herbicides fluazifop‐ p ‐butyl and fomesafen commercial mixture these on microbial activity a soil, cultivated with common bean under no‐till (NTS) conventional‐till (CTS) systems, were evaluated. Microbial respiration was monitored for 63 days after (DAA) herbicides, following evaluated at 12 51 DAA: biomass carbon (MBC), quotient ( q MIC), metabolic CO 2 ), percentage root colonisation by mycorrhizal fungi grain yield end cycle. A greater respiratory...
During recent years, many studies appeared on microbial solubilization of insoluble phosphates as an alternative chemically based P-fertilizer production and bearing in mind the progressive increase prices high global P consumption scarcity rock phosphate reserves. This biotechnological approach is mainly related to organic acids such citric, oxalic, gluconic, itaconic, lactic acid, which react with P-sources. The most applied studied P-solubilizers are fungal microorganisms cultivated...
The competition between weeds and crops is a topic of great interest, since this interaction can cause heavy losses in agriculture. Despite the existence some studies on subject, little known about importance soil microorganisms modulation weed-crop interactions. Plants compete for water nutrients ability given species to use available resources may be directly affected by presence microbial groups commonly found soil. Arbuscular mycorrhizal fungi (AMF) are able associate with plant roots...
Endophytic bacteria colonize the internal tissues of plants without causing infection or negative effects on their hosts. This study investigates occurrence and diversity culturable endophytic in fruits of Coffea canephora at three developmental stages. Isolation quantification were performed R2A culture medium, was established using molecular methods analysis fatty acid methyl esters (FAME). α- γ-Proteobacteria, Actinobacteria, Firmicutes, and Bacteroidetes identified investigated...
Studies on the ecology of organisms involved in production process are necessary for development sustainable agriculture, and sustainability is currently closely linked to profitability production. The objective this study was verify occurrence arbuscular mycorrhizal fungi weeds infesting Brazilian crops evaluate inorganic phosphate solubilization potential associated microbiota. A total 36 weed species were evaluated mycorrhizae; these, 11 selected their relative solubilization. All...
The retreat of glaciers in Antarctica has increased the last decades due to global climate change, influencing vegetation expansion, and soil physico-chemical biological attributes. However, little is known about microbiology diversity these periglacial landscapes. This study characterized compared bacterial fungal using metabarcoding samples from Byers Peninsula, Maritime Antarctica. We identified communities by amplification 16 S rRNA region V3-V4 internal transcribed spacer 1 (ITS1). also applied

Abstract The elemental ratios of plant tissues are associated with the adaptive and competitive success a species in an ecosystem. So far, no study has evaluated if how crop–weed competition influences competing populations, although such information is important to understand weed infestation dynamics improve management agroecosystems. objective this was analyze weed–crop during interspecific between weeds crops greenhouse experiments. For this, maize ( Zea mays L.) Amaranthus viridis L,...
