Virus in Araceae

From: "Agoston Janos" <agoston.janos at citromail.hu> on 2007.01.11 at 10:32:37(15078) Dear All, My professor in the Uni is researching in Viruses. +More I have got virus in my Typhonium giganteum, Zantedeschia albomaculata and Z. rehmannii. Sypthoms: reduced tuber growth, spathe distortion, leaf mosaic, wavy leaf, rounder leafshape (Z. rehmannii) and increased offset production. The sympthomes are not allways visible sometimes only one or two of them on a plant. Unfortunately they are now in dormancy, so we cannot check and identify the viruses with a scanning electro microscope, or with PCR. I would like to ask you kindly if anybody know any virus which can infect Araceae. To help us finding a marker or primer for the survey, please? Maybe a student will do a thesis about this to see what percent of the tubers are infected on the market. Thank you for your kind! I attach a picture of the spathe distortion. Any information is very wellcome!

Mosaic virus seems to be a a well known virus.I'm not sure if the odd inflorescence in your photo is from a virus, it is so commonly seen. Sometimes one inflor. is odd, but all the others on the plant are OK. Doesn't a virus mean a plant is unhealthy? If a plant has a virus, can it (the plant) survive through several dormancies?SusanAgoston Janos wrote: Sypthoms: reduced tuber growth, spathe distortion, leaf mosaic, wavy leaf, rounder leafshape (Z. rehmannii) and increased offset production.

Zommerschoon is the oldest TBV infected variety. In Hortus Bulborum (in Limmen) they keep this plant for many years now. First it was described about 1620. And today the tulips are well. +More ----- Original Message ----- From: Susan B To: Discussion of aroids Sent: Friday, January 12, 2007 3:41 AM Subject: Re: [Aroid-l] Virus in Araceae virusesIf you google Zantedeschia virus you will find lots of information.
