The effects of differing cytokinin and auxin concentrations on resistance of tobacco (Nicotiana tabacum L.) tissue cultures to race 0 of Phytophthora parasitica var. nicotianae were examined. With 1 micromolar kinetin and either 11.5 micromolar indoleacetic acid or 1 micromolar 2,4-dichlorophen-oxyacetic acid, tissues from resistant cultivars exhibited a "hypersensitive" reaction to zoospores o...

We have investigated nuclear changes induced in tomato (Lycopersicon esculentum) plant roots by two different pathogens, a phytoplasma of the stolbur group and the soil-borne fungus Phytophthora nicotianae var. parasitica, using light and electron microscopy as well as flow cytometry. Our results show that both pathogens strongly influenced nuclear structure, causing pyknosis and chromatolysis,...

Most of the methods adopted for processing of decayed fruits and degradation of wastes are not economical. In order to achieve 100% resource recovery from wastes, a novel type of waste treatment is to be followed, so that, the recovered byproducts could be used as biofertilizers. The objective of this study is identification of bacteria for studying their phenotypic and genotypic characters usi...

Management of plant diseases is a subject concern for researchers as well growers. Different management practices are being developed and used to combat the rising number pathogens, which threaten nursery crop production. Use cover crops sustainable soilborne explored an alternative strategy chemicals. However, potential threat these acting secondary host devastating pathogens has not been desc...
