Terfezia arenaria is a desert truffle native to the Mediterranean Basin region, highly appreciated for its nutritional and aromatic properties. Despite increasing interest in this truffle, T. not listed as an edible authorized trade European Union. Therefore, our objective was showcase arenaria’s chemical composition volatile profile. The analysis showed that good source of carbohydrates (67%),...

gridded maps of biomass to be produced over time6. Radar backscatter is sensitive to vegetation fresh biomass7. At long wavelengths (0.7 m or longer), radar penetrates deep into the canopy and the backscatter energy depends on a combination of variables including the size, number density, and the water content and wood specific gravity of branches and stems. However, radar backscatter suffers f...

Abstract The monoculture situation of truffle cultivation is favoring the appearance pests that would not be economically important in naturally balanced forest ecosystems. most prominent them European beetle Leiodes cinnamomeus (Panzer) (Coleoptera: Leiodidae), for which there are no effective control methods capable reducing its populations. potential mass trapping technique against this beet...

Tuber floridanum is the first truffle species reported in Brazil and little known about its nutritional properties ecology. Therefore, this study aimed to (1) determine T. aroma (2) analyze cultivation fruiting conditions, including potential crop pests market value. Fruiting bodies of showed a slightly ellipsoid shape smooth shallow groovy surface. The mass ascocarps ranged from 0.13 g 15.95 g...

The aim of this study was to investigate the influence of vine water status on bouquet typicality, revealed after aging, and the perception of three aromatic notes (mint, truffle, and undergrowth) in bottled fine red Bordeaux wines. To address the issue of the role of vine water deficit in the overall quality of fine aged wines, a large set of wines from four Bordeaux appellations were subjecte...

The fruiting bodies of the ectomycorrhizal (ECM) fungus Tuber melanosporum are usually collected in an area devoid of vegetation which is defined as a 'burnt area' (brulé in French). Here, the soil fungal populations of inside and outside brulé were compared in order to understand whether the scanty plant cover was related to a change in fungal biodiversity. Both denaturing gradient gel electro...

There are about 2500 recorded species of edible mushrooms. The most expensive and sought after of these mushrooms belong to the mycorrhizal group and include Tuber melanosporum Vitt. (Périgord black truffle), Tuber magnatum Pico & Vitt. (Italian white truffle), Tricholoma matsutake (Ito & Imai) Sing. (matsutake), Boletus edulis Bull: Fr. sensu lato (porcini) Cantharellus cibarius Fr.: Fr. (chan...

BACKGROUND Tuber melanosporum, also known in the gastronomic community as "truffle", features one of the largest fungal genomes (125 Mb) with an exceptionally high transposable element (TE) and repetitive DNA content (>58%). The main purpose of DNA methylation in fungi is TE silencing. As obligate outcrossing organisms, truffles are bound to a sexual mode of propagation, which together with TEs...

The ascomata and mycorrhizae of Tuber indicum s.l. were collected under the forest of broad-leaf species Populus yunnanensis and Quercus pannosa in the field respectively. The symbiotic relationships of both trees with T. indicum were examined and affirmed based on morphology and ITS-rDNA sequences. These two mycorrhizal combinations were successfully produced on artificially controlled substra...
