As one of the major agricultural crops, the cultivated potato is consumed each day by millions of people from diverse cultural backgrounds. A product of global importance, the potato tuber contains toxic glycoalkaloids (GAs) that cause sporadic outbreaks of poisoning in humans, as well as many
In May 2005, an estimated 10 to 15% mortality of various cultivars of false cypress (also named Lawson cypress or Port-Orford-cedar [Chamaecyparis lawsoniana]) with severe wilt was observed in field stands of an ornamental nursery in western Hungary. Wilted plants had rot-associated reduction of
Landraces of the Solanum tuberosum Andigenum group are abundant and diverse. They are a valuable genetic resource possessing resistance to pests, diseases, and environmental stresses. In the Andean region, populations of the false root-knot nematode Nacobbus aberrans became specialized to infect
False smut, caused by Ustilaginoidea virens, occurs on rice, corn, and other Gramineae, but is of little economic importance. False or green smut of corn resembles most closely false smut of rice (1). During surveys in 2000 at Mississippi State University, Delta Experiment Station, Stoneville, 32
The Ns gene confers resistance of potato to Potato virus S (PVS). Sixteen German and Dutch potato cultivars, all registered in Poland, were found to be susceptible to PVS infection. However, scoring of the cultivars for the presence of the Ns-linked SCAR marker SC811(454) revealed additional
A variety of samples consisting of purified compounds (of various origins) and ethanol extracts from plants were assayed for their activity on the growth and initiation of crown-gall tumors on potato disks. The results demonstrated a high correlation between the ability of these compounds to inhibit
A Genome-Wide Association Study using 330 commercial potato varieties identified haplotype specific SNP markers associated with pathotype 1(D1) wart disease resistance. Synchytrium endobioticum is a soilborne obligate biotrophic fungus responsible for wart disease. Growing resistant varieties is the
Galsky et al. (10, 11) have reported that the inhibition and growth of crown gall tumors, initiated on potato discs by Agrobacterium tumefaciens, apparently has good agreement with 3PS in vivo antileukemic activity in mice. We have now modified and evaluated this assay for its potential use as a
To investigate the key factors affecting the reliability of the analytical results, a laboratory-performance study was attempted for the notified methods to detect genetically modified (GM) maize (CBH351) and GM potato (NewLeaf Plus and NewLeaf Y). The test samples were designed as three pairs of
Potato mop-top virus (PMTV) is classified as a plant quarantine virus in Korea. It is tested at import inspection sites. In this study, two sets of reverse transcription-hemi-nested polymerase chain reaction primers were developed to diagnose PMTV. In addition, modified- positive control plasmid was
Destructive maceration, a wide host range, and longevity in non-plant substrates has established Dickeya dianthicola (blackleg of potato) as a significant threat to potato industries worldwide. To protect these businesses, a specific and sensitive point-of-care D. dianthicola detection tool is
This article demonstrates a new kind of a highly sensitive lateral flow immunoassay (LFIA). It is based on the enlargement of the size of gold nanoparticles (GNPs) directly on the test strip after a conventional LFIA. Particle size enlargement is accomplished through the catalytic reduction of
A detection method using the polymerase chain reaction (PCR) was developed to detect genetically modified (GM) potato (NewLeaf Y potato; NL-Y), of which the mandatory assessment has not yet been completed in Japan. The potato sucrose synthase gene was used as an internal control. We designed a
A detection method using polymerase chain reaction (PCR) was developed to detect the genetically modified (GM) potato (NewLeaf Plus potato; NL-P), which has not been authorized as safe in foods in Japan. The potato sucrose synthase gene was used as an internal control. The DNA from NL-P specifically
