Sheared-root inocula of vesicular-arbuscular mycorrizal fungi

Article Abstract:

The production and utilization of sheared-root inocula of Glomus spp. was discussed. The viability and density of the root inocula and the potential for pelletization and usage as a gel carrier was also determined in the study. The methodology involved shearing aeroponically grown root inocula for up to 80 s. Results showed that shearing for up to 20 s produced root inocula with reduced particle size. In addition, the shearing process cleanly cuts the roots thus there is a limited loss of inoculum viability. Further tests showed that inoculum was enveloped in carrageenan and can be used as a gel carrier.

Polyphosphates in intraradical and extraradical hyphae of an arbuscular mycorrhizal fungus, Gigaspora margarita

Article Abstract:

The amount of polyphosphate in the intraradical and extraradical Gigaspora margarita hyphae has been estimated from repeated extractions with phenol-chloroform, trichloroacetic acid, and EDTA. The poly-P chain was longer in extraradical hyphae than in intraradical hyphae. Most of the polyphosphate was in the TCA- (short-chain) and EDTA-soluble fractions in the intraradical hyphae. In the extraradical ones it was present in EDTA- (long-chain) and PC-soluble (granular) fractions. G. margarita is an arbuscular mycorrhizal fungus.

Seasonal dynamics of arbuscular mycorrhizal fungal communities in roots in seminatural grassland

Article Abstract:

The various effects of symbiotic arbuscular mycorrhizal fungal (AMF) communities on the diversity, as well as the productivity of grassland plant communities are studied. The results prove that the amount of AMF present in seminatural grassland highly decreases in autumn.
