Plants colonized by AM fungi regulate further root colonization by AM fungi through altered root exudation
The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in...
متن کاملDiscriminating invasive fungal infection from colonization
We read with interest the article by Xie and colleagues reporting the impact of invasive fungal infection (IFI) on outcomes [1]. In a cohort of 318 intensive care unit patients with severe sepsis they found 90 patients with IFI (28.3%). Ninety-three per cent of the IFIs were caused by Candida species, 3% by Aspergillus species and 4% were unclassified. Predominant sites of infection were the lu...
متن کاملMicrobe management: application of mycorrhyzal fungi in sustainable agriculture
ing in the rhizosphere for decades, in the form of plant growth-promoting microorganisms. Efforts to incorporate microbial management into mainstream practices have not been successful. In fact, the same practices that increased yields in the last 50 years (namely fertilizers, herbicides, and pesticides) have largely eradicated natural rhizosphere microbes in agrosystems (Matson et al. 1997) an...
متن کاملComparison of Fungal Community in Black Pepper-Vanilla and Vanilla Monoculture Systems Associated with Vanilla Fusarium Wilt Disease
Long-term vanilla monocropping often results in the occurrence of vanilla Fusarium wilt disease, seriously affecting its production all over the world. In the present study, vanilla exhibited significantly less Fusarium wilt disease in the soil of a long-term continuously cropped black pepper orchard. The entire fungal communities of bulk and rhizosphere soils between the black pepper-vanilla s...
متن کاملEctomycorrhizal colonization slows root decomposition: the post-mortem fungal legacy.
The amount of carbon plants allocate to mycorrhizal symbionts exceeds that emitted by human activity annually. Senescent ectomycorrhizal roots represent a large input of carbon into soils, but their fate remains unknown. Here, we present the surprising result that, despite much higher nitrogen concentrations, roots colonized by ectomycorrhizal (EM) fungi lost only one-third as much carbon as no...
