Virus-induced gene silencing (VIGS) has been used routinely in Nicotiana benthamiana to assess functions of candidate genes and as a way to discover new genes required for diverse pathways, especially disease resistance signalling. VIGS has recently been shown to work in Arabidopsis thaliana and in tomato. Here, we report that VIGS using the tobacco rattle virus (TRV) viral vector can be used i...

Potato (Solanum tuberosum) is a valuable cultivated vegetable with high nutritional qualities containing variety of essential ingredients such as starch, vitamins and minerals. However cultivating potatoes significantly complicated by diseases caused number phytopathogens both bacterial fungal nature. Phytophthora infestan s, Alternaria sp., Phoma exigua , Rhizoctonia solani, Fusarium Verticill...

In potato ( Solanum tuberosum ) mitochondria, about two-thirds of the tRNAs are encoded by the mitochondrial genome and one-third is imported from the cytosol. In the case of tRNAGly isoacceptors, a mitochondrial-encoded tRNAGly(GCC) was found in potato mitochondria, but this is likely to be insufficient to decode the four GGN glycine codons. In this work, we identified a cytosolic tRNAGly(UCC)...

The intestinal epithelium has a critical roll in host defence. One specialised cell type involved in this function is the Paneth cell, which secretes many substances with antimicrobial properties in response to different stimuli. Under pathological conditions, changes in the Paneth cell number, morphology and location as well as in granule number, morphology and composition have been reported. ...

Steroidal glycoalkaloids occur in potatoes and are reported to impart resistance to phytopathogens including bacteria, fungi, and insects. Because glycoalkaloids can be passed to progenies during breeding programs designed to develop improved potatoes, it is of importance to determine the quality of desired characteristics and the composition of glycoalkaloids of new somatic hybrids. The object...

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...

OBJECTIVES Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. MATERIALS AND METHODS Phenol...
