First Report of Rose Rosette Virus Associated with Rose Rosette Disease Affecting Roses in California

A discovery 70 years in the making: characterization of the Rose rosette virus.

Rose rosette was first described in the early 1940s and it has emerged as one of the most devastating diseases of roses. Although it has been 70 years since the disease description, the rosette agent is yet to be characterized. In this communication, we identify and characterize the putative causal agent of the disease, a negative-sense RNA virus and new member of the genus Emaravirus. The viru...

Short communication. First report of Eggplant mottled dwarf virus in China rose in southern Spain

Eggplant mottled dwarf virus (EMDV, genus Nucleorhabdovirus, family Rhabdoviridae) is transmitted in nature by leafhoppers and its natural host range includes vegetable crops (eggplant, tomato, potato, pepper), ornamentals (pittosporum, honeysuckle, pelargonium) and wild plants (caper, Solanum nigrum). The prevalence of infections is generally very low. EMDV has been demonstrated to be the caus...

Pruning Contracts with Rosette

Contracts are a pragmatic tool for managing software systems, but programs using contracts suffer runtime overhead. If this overhead becomes a performance bottleneck, programmers must manually edit or remove their contracts. This is no good. Rather, the contracts should identify their own inefficiencies and remove unnecessary dynamic checks. Implementing contracts with Rosette is a promising wa...
