Recent surveys of belowground fungal biodiversity in México and USA have revealed many undescribed truffle species, including many in the genus Tuber. Here we describe seven new species: Tuber beyerlei, T. castilloi, T. guevarai, T. lauryi, T. mexiusanum, T. miquihuanense and T. walkeri. Phylogenetic analyses place these species within the Maculatum group, an understudied clade of small truffle...

The application of zeolite to soils increases cation exchange capacity, and as increases nutrient retention capacity. Imbalanced nutrient management is one of the reasons responsible for low yield of potato in Iran. This study was carried out in research field of Islamic Azad University; Arak Branch at central of Iran to evaluate effect of zeolite particles and phosphorus fertilizer on agro-phy...

in order to evaluate plant density and different nitrogen levels on protein percent, yield and nitrate accumulation in potato tuber cv. agria, a factorial experiment based on randomized complete block design with three replications was conducted in ardabil in 2006. factors included nitrogen levels: 0, 80, 160 and 200 kg ha-1 net nitrogen and plant densities: 5.5, 7.5 and 11 plant m-2. results s...

Soil-incorporated rotation/green manure crops were evaluated for management of potato early dying caused by Verticillium dahliae and Pratylenchus penetrans. After two years of rotation/green manure and a subsequent potato crop, P. penetrans numbers were less after 'Saia' oat/'Polynema' marigold, 'Triple S' sorghum-sudangrass, or 'Garry' oat than 'Superior' potato or 'Humus' rapeseed. The area u...

Tuberous sclerosis complex (TSC) is a rare disorder of tissue growth and differentiation, characterized by benign hamartomas in the brain and other organs. Up to 90% of TSC patients develop epilepsy and 50% become medically intractable requiring resective surgery. The surgical outcome of TSC patients depends on the accurate identification of the epileptogenic zone consisting of tubers and the s...

Rapid expansion of the processing potato industry has contributed to a significant increase in irrigated potato production in Manitoba. However, information is lacking regarding optimum rotations for local conditions. In 1998, a crop rotation study was initiated on a Wellwood silt loam near Carberry to identify crop rotations that optimized crop yield and quality while maintaining soil quality....

The identification of authentic plant species is important for the quality control of traditional herbal medicines. The Pinelliae Tuber described as the tuber of only Pinellia ternata in national pharmacopoeia of Korea, China, and Japan. However, the tubers and herbal medicines derived from Pinellia ternata are similar to those derived from P. tripartita, P. pedatisecta, and Typhonium flagellif...

Abstract Potato is the most important crop in Peru and late blight main disease affecting crop. However, new varieties that are resistant to often lack other traits farmers consumers prefer. Using participatory varietal selection, this study seeks identify clones with high potential become resistance but also feature a marketable tuber yield preferred agronomic traits. During 2016–2017, 36 prev...
