potato virus y (pvy) and potato leafroll virus (plrv) are two major viruses which reduce 10-90 percent of yield and quality of potato tubers. in the present study, the efficiency of different methods, including meristem culture, thermotherapy followed by meristem culture and electerotherapy followed by meristem culture in two cultivars (agria and marfona) infected by plrv or pvy were evaluated....
Potato is a valuable plant as a source of nutrition and as an industrial product. The modification and breeding of potato plants are very difficult, or even impossible, via the conventional plant breeding programs. However, plant biotechnology and tissue culture are reliable methods which can produce plant material for gene transformation using Agrobacterium as a vector. In this study, one-, tw...
Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10...
There is evidence that chloride (Cl―) can lead to both an improved hydration and water use efficiency in plants due its osmotic properties. The potato crop widely assumed be sensitive Cl―. This based on studies which found tuber yield or starch reductions following a Cl― fertilization. However, there are also contradictory reports could not find any detrimental effect of fertilization plant dev...
