Accurate projections of the future land carbon (C) sink by terrestrial biosphere models depend on how nutrient constraints on net primary production are represented. While nutrient limitation is nearly universal, current models do not have a C cost for plant nutrient acquisition. Also missing are symbiotic mycorrhizal fungi, which can consume up to 20% of net primary production and supply up to...

VAM fungi play a vital role in improving the nutrient quality plants, increasing plants’ growth, helping protect plants against pathogen, and helps protecting them from salinity drought. Their functions range stress reduction to bioremediation heavy metal-polluted soils. The current review paper focuses on metal absorption, accumulation, of arbuscular mycorrhizal alleviating plants. Arbuscular ...

to investigate the effect of on-farm seed priming and arbuscular mycorrhizal fungi in different amounts of phosphate fertilizer on emergence, yield and yield components of a semi-mid maturity corn hybrid (es-sensor), an experiment was conducted at the research station of agriculture college, bu-ali sina university in 2012 in a factorial randomized complete block design with three replications, ...

and inoculation with the arbuscular mycorrhizal fungi Glomus mosseae (Nicol. and Gerd.) Gerdmann and Trappe, Glomus intraradices Schenck and Smith or Glomus viscosum Nicolson on shoot apical growth of plantlets that had been micropropagated from MM 106 apple (Malus pumila L.) and Mr.S. 2/5 plum (Prunus cerasifera Ehrh.) rootstocks. Unfertilized and non-mycorrhizal plantlets showed no apical gro...

—Roots of 15 Mojave Desert plant species were assessed for arbuscular mycorrhizal (AM) colonization in spring and autumn 1999. Another 19 species were assessed in autumn only. Perennial species were AM colonized, whereas annual species contained very low levels of AM hyphae or were nonmycorrhizal. The nonnative tree Tamarix ramosissima was also nonmycorrhizal. Levels of hyphae changed over the ...

Fires are critical pathways of carbon loss from boreal forest soils, whereas microbial communities form equally critical controls over carbon accumulation between fires. We used a chronosequence in Alaska to test Read’s hypothesis that arbuscular mycorrhizal fungi should dominate ecosystems with low accumulation of surface litter, and ectomycorrhizal fungi should proliferate where organic horiz...
