Última Desarrollo de plántulas de tres especies tropicales en combinación con la inoculación micorrizica bajo inundación artificial. Colegio de Postgraduados Martínez Sánchez, Araceli. La presente investigación se realizó para contribuir en el conocimiento del uso de la inoculación con hongos micorrízicos vesículo arbúscular (HMVA) en especies tropicales bajo condiciones de inundación y no inundación en vivero, con el fin de obtener plantas de calidad. Por esta razón se estableció un experimento dentro de las instalaciones del Colegio de Postgraduados, Campus Montecillo, que consistió de dos fases; en la fase uno se evaluó el efecto de dos cepas micorrízicas (Glomus intraradices y Zac-19), en tres especies forestales tropicales, Tabebuia donnell-smithii, Tabebuia rosea y Haematoxylum campechiaium, se utilizó un diseño experimental con bloques completamente al azar. Las evaluaciones fueron mensualmente durante tres meses midiéndose...

Infoteca-e PARRON, L. M.; VIEIRA, F. A.; MIRANDA, J. C. C. de; TSUBOI, L. A.. O objetivo deste estudo foi avaliar o desenvolvimento inicial de Myrsine guianensis Aubl. (azeitona-do-mato) e Diospyros sericea A. DC. (olho-de-boi), função de duas doses de fósforo e da inoculação com fungos micorrízicos arbusculares (FMA) nativos do Cerrado. Ambas as espécies são lenhosas nativas de Matas de Galeria do Distrito Federal e apresentam potencial de utilização em plantios mistos destinados ao repovoamento de áreas degradadas. As mudas foram produzidas, em viveiro, irrigado, com 30% de sombreamento, em tubetes de 290 ml. O inoculante de fungos micorrízicos arbusculares constitui em uma mistura das espécies Glomus brasilianum, Glomus etunicatum, Gigaspora margarita e Scutellospora cerradensis. Como tratamentos, foram utilizados duas...

Ano: 1999 URL: http://www.infoteca.cnptia.embrapa.br/infoteca/handle/doc/568877 Soil microorganisms and their role in the interactions between weeds and crops Planta Daninha Massenssini,A.M.; Bonduki,V.H.A.; Melo,C.A.D.; Tótola,M.R.; Ferreira,F.A.; Costa,M.D.. The competition between weeds and crops is a topic of great interest, since this interaction can cause heavy losses in agriculture. Despite the existence of some studies on this subject, little is known about the importance of soil microorganisms in the modulation of weed-crop interactions. Plants compete for water and nutrients in the soil and the ability of a given species to use the available resources may be directly affected by the presence of some microbial groups commonly found in the soil. Arbuscular mycorrhizal fungi (AMF) are able to associate with plant roots and affect the ability of different species to absorb water and nutrients from the soil, promoting changes in plant growth. Other groups may promote positive or negative changes in plant... Tipo: Info:eu-repo/semantics/article Palavras-chave: Competition; Agriculture; Mycorrhizal fungi; PGPR; Ecology.

Mycorrhiza are a mutualistic symbiosis between fungi and plant roots, the main benefit to the plant being increased nutrient uptake. The arbuscular is the most important kind of mycorrhiza for agriculture and it is widespread in occurrence and distribution in most ecosystems. The aim of this work was to study the mycorrhizal status of the species of Commelinidae that occur in the State of Pernambuco. Plant roots, collected in ten municipalities, were washed, cleared in KOH, stained with Trypan blue in lactoglycerol and observed under a light microscope in order to assess presence and identification of the mycorrhizal type. Percentage of root colonization was evaluated by the gridline intersect method. Forty specimens representing 30 species were observed....

ABSTRACT Arbuscular mycorrhizal fungi make up an important ecological niche in ecosystems, and knowledge of their diversity in extreme environments is still incipient. The objective of this work was to evaluate the density and diversity of arbuscular mycorrhizal fungi in the soil of King George Island in the South Shetland Islands archipelago, Antarctica. For that, soil and roots of Deschampsia antarctica were collected at the brazilian research station in Antarctica. The spore density, species diversity and mycorrhizal colonization in the roots were evaluated. There was a low density of spores (27.4 ± 17.7) and root mycorrhizal colonization (6 ± 5.1%), which did not present statistical difference. Four species of arbuscular mycorrhizal fungi were...

Ano: 2017 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652017000401737 Expression of phenazine biosynthetic genes during the arbuscular mycorrhizal symbiosis of Glomus intraradices BJM León-Martínez,Dionicia Gloria; Vielle-Calzada,Jean-Philippe; Olalde-Portugal,Víctor. To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previously characterized eukaryotic genes, 30% were homologous to fungal coding sequences, and 9% showed homology to previously characterized bacterial genes. Among them, GintPbr1a encodes a homolog to Phenazine Biosynthesis Regulator (Pbr) of Burkholderia cenocepacia, an pleiotropic regulatory protein that activates phenazine production through transcriptional activation of the protein D isochorismatase...
