Quantification of Phytophthora infestans population densities and their changes in potato field soil using real-time PCR.

Tuber infection of Phytophthora infestans often occurs at harvest. However, it is difficult to accurately estimate the population densities of P. infestans in soil, especially Japanese soil.

Ability of plant pathogenic fungi and to react with airborne methyl jasmonate.

The pathogenic fungi and produce jasmonic acid. The application of volatile deuterium-labeled methyl jasmonate increased the amount of nonlabeled JA present in . These results indicate that the fungi have the ability to react with airborne methyl jasmonate in a manner similar to a plant.
