The Paleozoic Origin of Enzymatic Lignin Decomposition Reconstructed from 31 Fungal Genomes
Comparative analyses of 31 fungal genomes suggest that lignin-degrading peroxidases expanded in the lineage leading to the ancestor of the Agaricomycetes, which is reconstructed as a white rot species, and then contracted in parallel lineages leading to brown rot and mycorrhizal species.
Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists
Convergent evolution of the mycorrhizal habit in fungi occurred via the repeated evolution of a 'symbiosis toolkit', with reduced numbers of PCWDEs and lineage-specific suites of myCorrhiza-induced genes.
Obligate biotrophy features unraveled by the genomic analysis of rust fungi
The dramatic up-regulation of transcripts coding for small secreted proteins, secreted hydrolytic enzymes, and transporters in planta suggests that they play a role in host infection and nutrient acquisition.

The results indicate that the prevailing paradigm of white rot vs. brown rot does not capture the diversity of fungal wood decay mechanisms, and suggest a continuum rather than a dichotomy between the white-rot and brown-rot modes of wood decay.
The genome of Laccaria bicolor provides insights into mycorrhizal symbiosis
The predicted gene inventory of the L. bicolor genome points to previously unknown mechanisms of symbiosis operating in biotrophic mycorrhizal fungi, providing an unparalleled opportunity to develop a deeper understanding of the processes by which symbionts interact with plants within their ecosystem to perform vital functions in the carbon and nitrogen cycles that are fundamental to sustainable plant productivity.
454 Pyrosequencing analyses of forest soils reveal an unexpectedly high fungal diversity.
This study validates the effectiveness of high-throughput 454 sequencing technology for the survey of soil fungal diversity and identified the Agaricomycetes as the dominant fungal class.
Périgord black truffle genome uncovers evolutionary origins and mechanisms of symbiosis
The sequence of the haploid genome of T. melanosporum is reported, which at ∼125 megabases is the largest and most complex fungal genome sequenced so far and results from a proliferation of transposable elements accounting for ∼58% of the genome.

Detailed characterization of the ammonium transporter (AMT) family in the perennial species Populus trichocarpa indicates that they have key functions in reproductive organ development in poplar, and basic genomic and transcriptomic information for the poplar AMT family is provided.
Genome-wide identification of NBS resistance genes in Populus trichocarpa
The transcripts of only 34 NBS-LRR genes were detected in rust- Infected and non-infected leaves using a whole-genome oligoarray, and none showed an altered expression two days post inoculation.

It is shown that PtdMTP1, when expressed in yeast and Arabidopsis, forms homooligomers, a novel feature of CDF members, which is disrupted by reducing agents, indicating possible disulfide bridge formation.
