Beer has been one of the most consumed alcoholic beverages worldwide. However, the incorporation of adjuncts in the beer can add new organoleptic and functional characteristics to the beverage. For this, Beauregard sweet potato shows high potential due to being a rich source of starch and many
Phytophthora infestans, the causal agent of late blight, threatens potato production worldwide. An important tool in the management of the disease is the use of resistant varieties. Eleven major resistance genes have been identified and introgressed from Solanum demissum. However, new sources of
BACKGROUND
Alternaria solani is a known air-born deuteromycete fungus with a polycyclic life cycle and is the causal agent of early blight that causes significant yield losses of potato worldwide. However, the molecular mechanisms underlying the conidiation and pathogenicity remain largely
Three types of mutation were introduced into the sequence encoding the GDD motif of the putative replicase component of potato virus X (PVX). All three mutations rendered the viral genome completely noninfectious when inoculated into Nicotiana clevelandii or into protoplasts of Nicotiana tabacum
Nicotiana benthamiana was transformed with P1 or VPg cistron of Potato virus A (PVA, genus Potyvirus). For both transgenes, T1 progeny displayed (i) resistance to PVA infection, (ii) susceptibility, or (iii) systemic infection followed by recovery of new leaves from PVA infection (RC), regardless of
The major losses in nitrogen and free amino acids (FAA) of the potato during the add-back (A-B) process were in the pre-cooking and mash-mixing steps (Fig. 1). These losses were due to leaching of nitrogen compounds into the processing water and heating. The FAA pool of the potato is composed mainly
BACKGROUND
Potato starch is composed primarily of amylopectin and amylose in an approximately 3:1 ratio. Amylose is considered to be nutritionally desirable in North American and European markets, so there is interest in finding strategies to increase the amylose content of potato starch. There is
Phytophthora infestans is the cause of late blight, a devastating disease in potato and tomato. Many of the mechanisms underlying P. infestans pathogenesis and defense responses in potato are still unclear. We investigated the effects of P. infestans on the changes in the accumulation of secondary
OBJECTIVE
To investigate selected factors of two nonaerated compost teas (NCT) and mechanisms that influence the restriction of several fungal potato pathogens.
RESULTS
Two NCTs, made from either commercial compost, (CCT) or vineyard compost (VCT), were tested for their ability to suppress potato
The root-lesion nematode, Pratylenchus penetrans (de Man, 1880) Filipjev, 1936, is a common pathogen of potato in the United States east of the Rocky Mountains and frequently interacts with Verticillium dahliae to aggravate early dying disease (4). West of the Rocky Mountains, P. penetrans is
When attempting to quantify the volatile components of a food isolated by dynamic headspace trapping onto an adsorbent, the analyst has to select the most appropriate compounds to use as standards and at which stage of the analysis to add them. Factors to be borne in mind include the volatility of
BACKGROUND
Potato (Solanum tuberosum) is a global crop and by far the most important non-cereal crop in the world. Therefore, it is necessary to assure its safe consumption. This is especially relevant in the case of its cultivation in abandoned mining areas, where the population tends to return to
Potato cyst nematode Globodera rostochiensis is an obligate parasite of solanaceous plants, triggering metabolic and morphological changes in roots which may result in substantial crop yield losses. Previously, we used the cDNA-AFLP to study the transcriptional dynamics in nematode infected tomato
Measuring antioxidant activity using a biologically relevant assay adds important evidence to aid in understanding the role of phytochemicals based on data from in vivo and chemical assays of extrusion processed purple potato and pea flours. A cellular antioxidant activity assay could provide
Two field trials were carried out in two successive agricultural seasons to study the possibility of using silicon (Si) and Moringa seed extract (MSE) for reducing heavy metal contamination resulting from phosphate fertilizers addition to potato tubers. A randomized complete block design experiment
