A global phylogenomic analysis of the shiitake genus Lentinula.

Lentinula is a broadly distributed group of fungi that contains the cultivated shiitake mushroom, L. edodes. We sequenced 24 genomes representing eight described species and several unnamed lineages of Lentinula from 15 countries on four continents. Lentinula comprises four major clades that arose in the Oligocene, three in the Americas and one in Asia-Australasia. To expand sampling of shiitake mushrooms, we assembled 60 genomes of L. edodes from China that were previously published as raw Illumina reads and added them to our dataset. Lentinula edodes sensu lato (s. lat.) contains three lineages that may warrant recognition as species, one including a single isolate from Nepal that is the sister group to the rest of L. edodes s. lat., a second with 20 cultivars and 12 wild isolates from China, Japan, Korea, and the Russian Far East, and a third with 28 wild isolates from China, Thailand, and Vietnam. Two additional lineages in China have arisen by hybridization among the second and third groups. Genes encoding cysteine sulfoxide lyase (lecsl) and γ-glutamyl transpeptidase (leggt), which are implicated in biosynthesis of the organosulfur flavor compound lenthionine, have diversified in Lentinula. Paralogs of both genes that are unique to Lentinula (lecsl 3 and leggt 5b) are coordinately up-regulated in fruiting bodies of L. edodes. The pangenome of L. edodes s. lat. contains 20,308 groups of orthologous genes, but only 6,438 orthogroups (32%) are shared among all strains, whereas 3,444 orthogroups (17%) are found only in wild populations, which should be targeted for conservation.

Draft Genome Sequence of the White-Rot Fungus Obba rivulosa 3A-2.

We report here the first genome sequence of the white-rot fungus Obba rivulosa (Polyporales, Basidiomycota), a polypore known for its lignin-decomposing ability. The genome is based on the homokaryon 3A-2 originating in Finland. The genome is typical in size and carbohydrate active enzyme (CAZy) content for wood-decomposing basidiomycetes.

[Complex assessment of late side effects affecting quality of life - the "Debrecen model"]. / Életminõséget befolyásoló késõi mellékhatások komplex felmérése - a debreceni modell.

As the outcome of childhood cancer improved substantially during the last 3 decades, the attitude of pediatric oncology has changed from "cure at any cost" to "cure at least cost". We investigated factors affecting quality of life in long-term survivors of childhood cancer in the in- and outpatient clinics of the Department of Pediatric Hematology-oncology, Institute of Pediatrics, Medical and Health Science Center, Debrecen. As a part of a comprehensive follow-up care program, we focused our attention on nephrotoxicity, osteoporosis and on cardiovascular morbidity. For long-term survivors of childhood cancer sensitive and cost-effective diagnostic algorithms were developed that can help in guiding secondary and tertiary prevention programs, in addition to assessing accurately the condition of patients. We found that anti-cancer treatments, including some of the supportive interventions, have adverse effects on glomerular (10%) and tubular functions (37%), impair the balance of bone resorption and formation (69%) and increase the frequency of cardiovascular risk factors (62%) in a significant proportion of patients. Our data confirm and extend the findings of other investigators and cooperative groups. In conclusion, we consider it important that the treatment plans of high-risk patients with cancer should be aimed at preserving the anticancer potential of therapy, without enhancing the frequency and severity of complications. The presented "Debrecen model" may help in achieving this goal and in increasing quality of life of long-term survivors of childhood cancer.
