Article Synopsis
  • Ectomycorrhizal fungi, like Lactarius species, form beneficial partnerships with woody plants in forests, but their host specificity mechanisms are not well understood.
  • Genome sequencing of seven Lactarius species revealed that they have significantly larger genomes than other Russulales fungi, primarily due to transposable elements, and specific gene expansions related to their ecology.
  • The presence of specialized genes, such as proteases and lectins, may contribute to the unique host specificity of Lactarius fungi, indicating diverse genomic adaptations within this group.

Background: This work aimed at characterizing 12 isolates of the genus Tuber including Tuber melanosporum (11 isolates) and Tuber brumale (one isolate). This was done using internal transcribed spacer (ITS) sequences, confirming their origin.

Results: Analysis of their mating type revealed that both MAT1-1 and MAT1-2 exist within these isolates (with 3 and 8 of each, respectively).

To study the effects of local nitrate or ammonium supply on the architecture of the Cedrus atlantica root system, cedar seedlings were grown in split-root boxes in a growth chamber. In each box-compartment, roots were fertilized with a solution containing nitrogen, either as nitrate [Ca(NO(3))(2)] or ammonium (NH(4)Cl), supplied at 0.1 or 5.

Survival of the ectomycorrhizal fungal strain Suillus collinitus Sc-32 on Pinus halepensis after inoculation and outplanting was monitored in a Mediterranean plantation. Three molecular fingerprints were developed: RFLP of the internal transcribed spacer ribosomal DNA, intersimple sequence repeat, and a specific sequence-characterized amplified region marker. The inoculant was demonstrated to survive on inoculated seedlings 4 years after outplanting (56 months after inoculation), although S.

The study examined the diversity of ectomycorrhizal fungi, naturally established on roots of containerised Pinus seedlings in a nursery, using PCR-RFLP and sequencing of the nuclear ribosomal internal transcribed spacer. Seventy-two samples, including ectomycorrhizae and fruit bodies, were examined. Molecular typing assigned the fungal symbionts to four ectomycorrhizal Boletales: Rhizopogon rubescens, Suillus bovinus, S.
