Acúmulo de ácido oxálico e cristais de cálcio em ectomicorrizas de eucalipto.: I- produção de ácido oxálico e concentração de nutrientes em raízes laterais finas colonizadas por fungos ectomicorrízicos Accumulation of oxalic acid and calcium crystals in eucalypt ectomycorrhizas.: I- oxalic acid production and nutrient concentration in fine lateral roots colonized with ectomicorrhizal fungi

Revista Brasileira de Ciência do Solo, 2009
O eucalipto apresenta ótimo crescimento em solo com baixa fertilidade, mas pouco se sabe sobre a participação das ectomicorrizas e de ácidos orgânicos na aquisição e no acúmulo de nutrientes pela planta em campo. A produção de ácido oxálico e sua relação

MORPHOLOGICAL AND MOLECULAR CHARACTERIZATION OF ECTOMYCORRHIZAL FUNGI ISOLATED FROM EGYPTIAN ENVIRONMENT [PDF]

Arab Universities Journal of Agricultural Sciences, 2007
In a trial to isolate and identify ectomycorrhi-zal fungi for the first time in Egypt 13 sporocarpes associated with rang of plants grown on Egyptian soils were collected, to be used for this purpose.

Root diameter predicts the extramatrical hyphal exploration distance of the ectomycorrhizal fungal community

Ecosphere, 2018
Locally coexisting tree species of temperate forests often vary widely in the diameter of their absorptive roots, resulting in contrasting strategies of root foraging within soil nutrient hot spots. We hypothesized that root diameter would also influence

Is Tuber brumale a threat to T. melanosporum and T. aestivum plantations?

iForest - Biogeosciences and Forestry, 2018
True truffles in the genus Tuber are the most valuable ectomycorrhizal fungi and their cultivation has become widespread around the world. Competition with other ectomycorrhizal fungi and especially with undesired Tuber species, like T.

Carbon Allocation in Ectomycorrhizas: Identification and Expression Analysis of an Amanita muscaria Monosaccharide Transporter

Molecular Plant-Microbe Interactions, 1998
Ectomycorrhizas are formed between certain soil fungi and fine roots of predominantly woody plants. An important feature of this symbiosis is the supply of plant-derived carbohydrates to the fungus.

Morphological Characteristics of Ectomycorrhizas on Merbau [Intsia bijuga (Colebr.) O. Kuntze]

Hayati Journal of Biosciences, 2010
Merbau [Intsia bijuga (Colebr.) O. Kuntze] is one of valuable timber tree in south-east Asia which has been known having ectomycorrhizae (EcM) though being ignored.

A Novel Class of Ectomycorrhiza-Regulated Cell Wall Polypeptides in Pisolithus tinctorius

Molecular Plant-Microbe Interactions, 1999
Development of the ectomycorrhizal symbiosis leads to the aggregation of fungal hyphae to form the mantle. To identify cell surface proteins involved in this developmental step, changes in the biosynthesis of fungal cell wall proteins were examined in ...

Acúmulo de ácido oxálico e cristais de cálcio em ectomicorrizas de eucalipto.: II- formação de cristais de oxalato de cálcio induzida por fungos ectomicorrízicos em raízes laterais finas Accumulation of oxalic acid and calcium crystals in ectomycorrhizas of eucalypt.: II- calcium oxalate crystal formation induced by ectomicorrhizal fungi in fine lateral roots

Revista Brasileira de Ciência do Solo, 2009
O eucalipto é eficiente na aquisição de Ca do solo, mas pouco se sabe sobre a participação das ectomicorrizas e dos ácidos orgânicos nesse processo em campo. O acúmulo de cristais de Ca (CaOx) foi avaliado em, aproximadamente, 2.100 raízes laterais finas

Comparative mitogenome analysis of two ectomycorrhizal fungi (Paxillus) reveals gene rearrangement, intron dynamics, and phylogeny of basidiomycetes

IMA Fungus, 2020
In this study, the mitogenomes of two Paxillus species were assembled, annotated and compared. The two mitogenomes of Paxillus involutus and P. rubicundulus comprised circular DNA molecules, with the size of 39,109 bp and 41,061 bp, respectively ...
