Taxonomic Review of the Genus Rosa

"Species of the genus Rosa have always been known for their beauty, healing properties and nutritional value. Since only a small number of properties had been studied, attempts to classify and systematize roses until the 16th century did not give any results. Botanists of the 17th and 18th century p...

Re: Full paper - what is rose rosette disease?

The full paper article is mainly historical.  I was disappointed to see that no mention was made of the extensive work of Ann Peck in publicizing the historical rose rosette virus science.

Re: Univ. Calif. Davis virus report (no date of preparation given)

Another interesting point (to me) is on slide 3 of the original link. This slide lists the viruses that they consider belong under the heading "Rose Mosaic Viruses". In addition to the common three (PNRSV, ApMV, and ArMV), they specifically list Prune Dwarf Virus, PDV and also include an "Others". I...

Re: Univ. Calif. Davis virus report (no date of preparation given)

The following Davis link has a 2018 copyright so it should be a reasonably up to date summary of the field. http://fps.ucdavis.edu/roses.cfm It has this to say about the historical use of heat treatment to create virus free roses: "Heat treatment works well for many cultivars but others die in the h...

Professor Tzanetakis seeking a post doctorate for plant virus studies

One of the advanced American plant virus Professors is seeking a post doctorate to assist him in plant virus studies. I feel that he has been one of the leaders in utilizing next generation sequencing techniques for plant virus detection. I would expect that this would be an ideal sabbatical positio...

Re: / Honeybee population isn't ‘crashing’ and seed pesticides are not driving health problems

The following was stated: "The EU ban on neonicoinoids is way more politically based than scientifically based and the price will be harsh. There will be higher food prices in the rich EU and food shortages that will be worse the lower down the economic ladder you go." This is what was stated as the...
