Arbuscular Mycorrhizal Fungi Associated with Maize ( L.) in the Formation and Stability of Aggregates in Two Types of Soil.

Knowledge of native Arbuscular Mycorrhizal Fungi (AMF) and their relationship with the edaphic characteristics where they live is important to establish the influence of allochthonous AMF, which were inoculated, on the development and stability of soil aggregates. The objectives of this research were to know the composition of native AMF species from two contrasting soils, and to establish the development and stability of aggregates in those soils with corn plants after inoculating them with allochthonous AMF. The experiment had three factors: Soil (two levels [S1 and S2]), HMA (three levels: without application [A0], with the application of [A1] and with the application of a consortium [A2]) and Fertilization (two levels (without fertilization [f0] and with fertilization [f1])).

Silencing of the Laccase () Gene from Causes Important Effects on the Formation of Toxocyst-like Structures and Fruiting Body.

A wide variety of biological functions, including those involved in the morphogenesis process of basidiomycete fungi, have been attributed to laccase enzymes. In this work, RNA interference (RNAi) was used to evaluate the role of the laccase () gene of PoB. Previously, transformant strains of were obtained and according to their level of silencing they were classified as light (T7), medium (T21) or severe (T26 and T27).

Physiological Responses of to Inoculation with Autochthonous and Allochthonous Arbuscular Mycorrhizal Fungi.

The benefits of mycorrhizal interactions are only known in 8 of 210 recognized taxa. We evaluated the effects of autochthonous and allochthonous arbuscular mycorrhizal fungi (AMF) on growth and nutrient assimilation in . The autochthonous consortium (Cn) of eight species was propagated from the rhizospheric soil of , while (Cc) and (Ce) were employed as allochthonous AMF.
