Fungi and bacteria were isolated from surface disinfected leaf tissues of several citrus rootstocks. The principal bacterial species Alcaligenes sp., Bacillus spp. (including B. cereus, lentus, megaterium, pumilus, subtilis), Burkholderia cepacia, Curtobacterium flaccumfaciens, Enterobacter cloacae, Methylobacterium extorquens, Pantoea agglomerans, with P. agglomerans pumilus being the most frequently species. abundant fungal Colletotrichum gloeosporioides, Guignardia citricarpa,...
Fusarium proliferatum is an important pathogen that associated with plant diseases and primarily affects aerial parts by producing different mycotoxins, which are toxic to humans animals. Within the last decade, this fungus has also been described as one of causes red root rot or sudden death syndrome in soybean, extensive damage crop. This study describes Agrobacterium tumefaciens-mediated transformation F. a tool for disruption pathogenicity genes. The genetic was performed using two...
The mangrove ecosystem is a coastal tropical biome located in the transition zone between land and sea that characterized by periodic flooding, which confers unique specific environmental conditions on this biome. In these ecosystems, vegetation dominated particular group of plant species provide environment harboring diverse groups microorganisms, including endophytic microorganisms are focus study. Because their intimate association with plants, could be explored for biotechnologically...
Endophytes are being considered for use in biological control, and the enzymes they secrete might facilitate their initial colonization of internal plant tissues direct interactions with microbial pathogens. Microbial proteases also biotechnologically important products employed bioremediation processes, cosmetics, pharmaceutical, photographic food industries. In present study, we evaluated antagonism competitive between 98 fungal endophytes Alternaria alternata, Colletotrichum sp.,...
Endophytic fungi have been described as producers of important bioactive compounds; however, they remain under-exploited exopolysaccharides (EPS) sources. Therefore, this work reports on EPS production by submerged cultures eight endophytes isolated from
Guarana (Paullinia cupana var. sorbilis) is a plant from the Amazonas region with socio-economic importance. However, guarana production has been increasingly affected by unfavorable conditions resulting anthracnose, caused Colletotrichum fungal genus, which primarily affects mainly region. The aim of present study was to isolate bacterial endophytes seeds plants obtained and Northeast state Bahia, where this disease not problem for plantations. number Colony Forming Units (CFU/g seeds) 2.4...
The protective and growth-promoting activities of Colletrotrichum Diaporthe endophytes on tomato plants (Lycopersicon esculentum Mill.) are underexplored. We screened 40 endophytic fungi associated with Mexican shrimp plant (Justicia brandegeana) using an in vitro dual culture assay for Fusarium oxysporum, one the most important phytopathogens plants. three best antagonists, Colletotrichum siamense (JB224.g1), C. (JB252.g1), masirevicii (JB270), were identified based multilocus sequence...
from the endophyte and plant pathogen, pathogen growth area was measured.The endophytic strains G-01, G-02, G-03 were effective against Fusarium solani Didymella bryoniae.The rDNA regions corresponding to internal transcribed spacer 1-5.8S-internal 2 sequenced, results compared with sequences deposited in NCBI database.The identified as Diaporthe citri.This identification confirmed by phylogenetic analysis.The crude extract of secondary metabolites G-01 strain tested Escherichia coli...
Because of human population growth, increased food production and alternatives to conventional methods biocontrol development plants such as the use endophytic bacteria fungi are required. One used study microorganism diversity is sequencing 16S rRNA gene, which has several advantages, including universality, size, availability databases for comparison. The objective this was analyze bacterial in agricultural crops using published papers, sequence databases, phylogenetic analysis. Fourteen...
Endophytic fungal communities associated with two ethno-medicinal plants of Similipal Biosphere Reserve, India and their antimicrobial prospective S. K. Jena, Tayung
Fungi belonging to the Colletotrichum genus can be categorized as endophytic or phytopathogenic.These fungi infected by viruses, termed mycoviruses, which are known promote hypovirulence in fungi.However, there few studies that have described mycoviral infections of endophytes.The production secondary metabolites endophytes with antimicrobial potential inhibiting numerous pathogens has gained increasing attention.The aim current study was investigate presence mycoviruses and phytopathogenic...
In the present study, biological activity and chemical composition of two crude extracts endophytic fungal strains Bipolaris genera isolated from species aquatic macrophytes: Eichhornia azurea (Kunth) crassipes (Mart.) were investigated. The nuclear magnetic resonance mass spectrometry data provided identification three main compounds: curvulin (1), spirostaphylotrichin R (2) U (3). fragmentation mechanism precursor ions towards collision induced dissociation (CID) tandem experiment (MS/MS)...
Endophyte microorganisms have great biotechnological interest, with features applicable to different areas and are potentially useful in agriculture. The current study determines the potential of endophytic fungi, isolated from leaves Sapindus saponaria, control phytopathogenic fungi evaluate their enzyme production. Molecular taxonomy was performed by sequencing ITS1-5.8S-ITS2 ribosomal DNA region, identifying genera Phomopsis, Sordariomycetes, Diaporthe, Colletotrichum. In vitro antagonism...
Various organisms such as fungi and bacteria can live inside plants, inhabiting the aerial parts (primarily leaves) without causing damage. These microorganisms, called endophytes, produce an extensive variety of compounds that be useful for medical agronomic purposes. Trichilia elegans A. Juss., belonging to Meliaceae family, shows wide dispersion in South America, phytochemical analyses from these plants endophyte isolates have shown biological activity. Accordingly, aim this study was...
