Activation of Pathogenesis-related Genes by the Rhizobacterium, Bacillus sp. JS, Which Induces Systemic Resistance in Tobacco Plants.

Plant growth promoting rhizobacteria (PGPR) are known to confer disease resistance to plants. Bacillus sp. JS demonstrated antifungal activities against five fungal pathogens in in vitro assays.

A realization of sound focused personal audio system using acoustic contrast control.

A personal audio system that does not use earphone or any wire would have great interest and potential impact on the audio industries. In this study, a line array speaker system is used to localize sound in the listening zone. The contrast control [Choi, J.

Identification of rice genes induced in a rice blast-resistant mutant.

To clarify mechanisms of rice blast resistance in rice plants we used suppression subtractive hybridization (SSH) to isolate genes induced upon rice blast inoculation in a rice blast-resistant mutant. A total of 26 rice cDNAs were isolated and found to have elevated expression upon rice blast infection in a rice blast-resistant derivative, SHM-11, of the rice cultivar, Sanghaehyanghyella. Sequencing of the cDNAs revealed that many of the proteins they encoded had been previously described as involved in plant responses against pathogen attack.
