Coreplication experiments have revealed that replication of turnip yellow mosaic virus (TYMV) RNA in turnip protoplasts is cis-preferential. Genomes encoding mutant p141 or p66, proteins essential for virus replicatio ...

We have developed crown-gall resistant transgenic plants capable of suppressing Agrobacterium tumefaciens T-DNA oncogenes. Crown gall tumors result from overproduction of auxin and cytokinin in plant cells transformed by ...

Little is known about the virulence factors of Renibacterium salmoninarum, the causative agent of salmonid bacterial kidney disease. The predominant protein produced by R. salmoninarum in broth culture or during infec ...

Myxobolus cerebralis, a myxozoan parasite that infects almost all species of wild and cultured salmonids, was first identified in northeastern Oregon in the Lostine River in 1986. Fish that are heavily infected with M. ...

Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation ...

Disseminated neoplasia (DN) is a proliferative cell disorder that occurs in the circulatory system of bivalves. The condition is progressive and lethal. At least 15 species of bivalves over a wide range of geographic l ...
