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...

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...

The cultivar selection and nitrogen (N) fertilization are key management factors to improve potato yield. aim of the present study was evaluate ecophysiological determinants biomass tuber yield in genotypes response N availability under field conditions. Experiments 1 2 were carried out a volcanic soil southern Chile during 2021–2022 season. Treatments applied factorial combination (i) fifteen ...

The potato tuber moth (Phthorimaea operculella Zeller) is the primary insect pest of cultivated potato (Solanum tuberosum L.) in tropical and subtropical regions, causing both foliar and tuber damage. In contrast, the Colorado potato beetle (Leptinotarsa decemlineata Say) is the most important insect pest in the northern potato production latitudes. The codon-modified Bacillus thuringiensis Bt-...

The yacon (Smallanthus sonchifolius) tuber was examined with regard to its prebiotic effects compared with commercialized fructo-oligosaccharides (FOS). A feed containing 10% yacon tuber, which is equivalent to 5% commercialized FOS in terms of the amount of fructo-oligosaccharides (GF2, GF3 and GF4), was administrated to rats for 28 days. The yacon diet changed the intestinal microbial communi...

Resistance to Meloidogyne chitwoodi was introgressed from Solanum bulbocastanum into the cultivated gene pool of potato. A single dominant gene is responsible for resistance to race 1 reproduction on the root system. An additional form of resistance was discovered in certain advanced backcross clones. A BC(5) clone, PA99N82-4, resisted invasion of tubers by available nematode juveniles whether ...
