Dickeya solani is one of the most important pectinolytic phytopathogens responsible for high losses in potato, especially in seed potato production in Europe. Lytic bacteriophages can affect the structure of the host population and may influence spread, survival and virulence of the pathogen and in consequence, infection of the plant. In this study, we aimed to acquire information on the viabil...

Tuber and root crops virtually exclusively accumulate storage products in the form of carbohydrates. An exception is yellow nutsedge (Cyperus esculentus) in which tubers have the capacity to store starch and triacylglycerols (TAG) in roughly equal amounts. This suggests that a tuber crop can efficiently handle accumulation of energy dense oil. From a nutritional as well as economic aspect, it w...

Improving understanding and prediction of the potato (Solanum tuberosum) tuber size over the growing season is important due to its effects on crop price and marketing. Several models have been proposed to describe potato growth and development, but are based on short-term data and have little use for predicting yields or in-season management decisions. This analysis uses long-term data collect...

this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...

the aim of this study was to examine factors affecting adoption of mini-tuber seed potato. survey research design was used in this study. a sample of 100 potato growers who were informed about mini-tuber was selected and divided into adopter and non-adopter groups. questionnaire was used as the instrument for data collection and was validated by a panel of experts. a pilot study was conducted f...

the sugar beet weevil, lixus incanescens boh., is an important insect pest of sugar beet, beta vulgaris l., in razavi khorasan province. in this research, population densities of the sugar beet weevil eggs and larvae were evaluated on plants of six sugar beet cultivars including ardabili, aras, persia, flores, laetitia and rosire in an experimental field in 2011 and 2012. also, the percentage o...

Reactivation of dormant meristems is of central importance for plant fitness and survival. Due to their large meristem size, potato (Solanum tuberosum) tubers serve as a model system to study the underlying molecular processes. The phytohormones cytokinins (CK) and gibberellins (GA) play important roles in releasing potato tuber dormancy and promoting sprouting, but their mode of action in thes...

Both paclitaxel and docetaxel are mitotic inhibitors with similar mechanisms of action. In our patient, CME was thought to be secondary to paclitaxel use. Paclitaxel treatment was discontinued and capecitabine (Xeloda; Hoffman-LaRoche Inc, Nutley, NJ) was prescribed by the patient’s oncologist. Six weeks after cessation of paclitaxel treatment, the patient’s bestcorrected visual acuity improved...
