Two soil extraction methods were compared to determine their efficiency in recovering cysts and juveniles of a tobacco cyst nematode, Globodera tabacum solanacearum. The methods were equally efficient when extracting nematodes from soil samples seeded in the laboratory; however, there was a significant extraction method x month interaction when the methods were used to estimate field soil popul...

Nematodes that parasitize plant roots cause huge economic losses and have few mechanisms for control. Many parasitic nematodes infect plants by reprogramming root development to drive the formation of feeding structures. How nematodes take control of plant development is largely unknown. Here, we identify two host factors involved in the function of a receptor ligand mimic, GrCLE1, secreted by ...

certain potato cultivars such as native potato species (nps) from the andes are known to have resistances to different pests and diseases. some accessions are also interesting from a nutritional and culinary perspective. a collection of 35 nps and 11 old spanish accessions were analysed for streptomyces scabies, rhizoctonia solani and globodera rostochiensis, as well as dry matter, reducing sug...
