MOSAIC CROSS-INOCULATION AND INSECT TRANSMISSION STUDIES

Structural insights into the molecular mechanisms of cauliflower mosaic virus transmission by its insect vector.

Cauliflower mosaic virus (CaMV) is transmitted from plant to plant through a seemingly simple interaction with insect vectors. This process involves an aphid receptor and two viral proteins, P2 and P3. P2 binds to both the aphid receptor and P3, itself tightly associated with the virus particle, with the ensemble forming a transmissible viral complex. Here, we describe the conformations of both...

Transmission Biology of Rice Stripe Mosaic Virus by an Efficient Insect Vector Recilia dorsalis (Hemiptera: Cicadellidae)

Rice stripe mosaic virus (RSMV) is a newly discovered species of cytorhabdovirus infecting rice plants that is transmitted by the leafhopper Recilia dorsalis. In this study, the transmission characteristics of RSMV by R. dorsalis were investigated. Under suitable growth conditions for R. dorsalis, the RSMV acquisition rate reached 71.9% in the second-generation population raised on RSMV-infecte...

Biolistic inoculation of gladiolus with cucumber mosaic cucumovirus.

A new method of inoculation of gladiolus with cucumber mosaic virus (CMV) was developed using the Bio-Rad Helios Gene Gun System. This method circumvents the traditional use of aphids to transmit CMV, a virus that is mechanically transmissible to many plant species but only with difficulty to gladiolus. Cartridges containing virus-coated gold microcarriers were prepared and the virus shot into ...

Studies on "mosaic fungus".

The so-called "mosaic fungus" is a frequent finding in the routine examinations of skin scrapings for superficial pathogenic fungi. It may be found alone or with regular mycelium, with arthrospores or with both. There is, as yet, no agreement as to the nature of the "mosaic fungus," and the investigators may be separated into two groups—those who claim that the structure is an artefact (1—4) an...
