PLOS Pathogens: Plant Virus Ecology

PLOS Pathogens: Plant Virus Ecology | Plant Virology | Scoop.it

Viruses have generally been studied either as disease-causing infectious agents that have a negative impact on the host (most eukaryote-infecting viruses), or as tools for molecular biology (especially bacteria-infecting viruses, or phage). Virus ecology looks at the more complex issues of virus-host-environment interactions. For plant viruses this includes studies of plant virus biodiversity, including viruses sampled directly from plants and from a variety of other environments; how plant viruses impact species invasion; interactions between plants, viruses and insects; the large number of persistent viruses in plants that may have epigenetic effects; and viruses that provide a clear benefit to their plant hosts (mutualists). Plants in a non-agricultural setting interact with many other living entities such as animals, insects, and other plants, as well as their physical environment. Wild plants are almost always colonized by a number of microbes, including fungi, bacteria and viruses. Viruses may impact any of these interactions [1].

Nice, reasoned review on something most human and animal virologists take no notice of whatsoever...B-)  OK, she does have "Plant Virus Biodiveristy" as her first heading, but hey, I misspelled my own name on my second paper when referring to my first!

 

The bottom line is that we notice plant viruses when they do things to our crop plants or companion plants - and not when they are in their natural (read: non-agricultural / horticultural) setting.  As Marilyn points out, plant viruses may interact with plant host, insect vector and humans - and with other pathogens and commensals and symbionts, making for a potentially VERY complex ecosystem.

 

Interestingly, "wild" plant viruses often cause persistent infections, and are efficiently transmitted vertically - and may even, as in the begomovirus-infected Abutilon, give rise to a pleasing phenotype that has resulted in spread, via cultivation, around the world.

 

The world needs more plant virologists.  It certainly has enough plant viruses!

Biological and molecular events associated with simultaneous transmission of plant viruses by invertebrate and fungal vectors

Biological and molecular events associated with simultaneous transmission of plant viruses by invertebrate and fungal vectors | Plant Virology | Scoop.it

Viruses are likely to be the most dangerous parasites of living organisms because of their widespread occurrence, possible deleterious effects on hosts and high rates of evolution. Virus host-to-host transmission is a critical step in its life cycle because it enables not only virus survival in a given environment but also efficient dissemination. Since hosts of plant viruses are not mobile, these pathogens have adopted diverse transmission strategies, which involve various vector organisms, mainly arthropods, nematodes, fungi and protists. In nature, plants are often infected with more than one virus at a time, thereby creating potential sources for vectors to acquire and transmit simultaneously two or more viruses. Simultaneous transmission can further result in multiple infections of new host plants, which become subsequent potential sources of the viruses, thus enhancing the spread of the diseases caused by these pathogens. Moreover, it can contribute to the maintenance of viral genetic diversity in the host communities. However, despite its possible significance, the problem of simultaneous transmissions of plant viruses by their vectors seems to be insufficiently investigated. In this review, the current knowledge about multiple viral transmissions by aphids, whiteflies, leaf- and planthoppers, nematodes, and fungi, is outlined.
