I want to pollinate my vulcanicola with pollen from a sang that looks sick.......maybe virused. I toss my brugs as soon as they look funny so I am hesitating bringing the pollen in from a friend's sang that looks sick but I want the differnt genes. I think I remember that Dennis said viruses are not transmitted thru pollen. I could be wrong.......LOL
Does anyone know?

Brug Viruses.....anyone know about them???
Is your vulcanicola open now Kell? We need photos if it is!
I've had some that looked bad, curled/mottled leaves. They came out of it with warm, dry weather. Did not throw any away.
LOL Deb! YES!! I have 11 blooms. I will take a pic later tonight. I just got in from planting 5 minutes ago. My DH came out and forced me in...........
I get those too Gloria. I toss them if they look too weird unless they are special. I have one know that is very weird. I only am keeping it because it is supposed to be a euro brug and I would just like to see it bloom once but I may not keep it. I will take a pic after dinner.
Pollen will not transmit any virus.
All plants( except variegated which is impossible to explain for me)grown from seeds are virusfree.
Gee, thanks Ludger for telling me that. So variegated plants do transmit viruses thru pollen and transmit virus on to their seed! But no other plants do! Very interesting.
See Ludger, just for you I am posting all my disease questions and problems! You can't call me chatty Kell all the time........LOL! The problem is that it seems not many of us if any, know the answers! But you did on this one and I do appreciate your sharing!
I just emailed Glory and asked her the same question. For some reason, I was afraid the pollen would carry some sort of social disease

LOL Roz............SAY AGAIN??????????????????
And did Glory tell you to take 2 aspirin and go to bed???
Like a virus that can be passed on by propagation. In people this is called a social disease.
Like a virus that can be passed on by propagation. In people this is called a social disease. I suppose it was an attempt at humor.
Thank goodness I wear gloves when I propagate! I could never explain a social disease to Tom!
It worked..........I laughed and laughed..........
You are so funny, Roz!
NOPE!!! Pollen from variegated donīt transmitt any virus.Because of this all brugseedlings pollinated with a variegated are GREEN......:)
If you use a variegated as a motherplant ( the seeds from there...) the virus which will cause the variegation is anywhere in the seed ( forgot the name) but not in the genes.Therefore most seedlings from variegated motherplants are just white, the virus became to strong........
Kell, sorry for not replying to the humor...can not translate it...
Yes, viruses can cause variegation, but variegation is not always caused by a virus. Regular structured green/white leaves are genetic, they follow Mendelian laws of inheritance. They contain something called "leucoplasts" which develop from protoplasts and part of them will differentiate into chloroplasts which produce green when exposed to light. The leucoplasts are like chloroplasts which have lost their ability to produce chlorophyll when exposed to light. White seedlings will show up due to double gene inheritance, they don't inherit the ability to produce chlorophyl.
There is also something called "Extrachromosomal inheritance" which can cause inherited variegation. It happens when you cross a variegated plant to a green plant, it follows Mendelian laws of inheritance. Seedlings will sometimes appear that are all green, green/white and all white because of their genetic structure(and the amount of green, green/white and all white seedlings follow Mendelian law)
Virus caused variegation is usually not a set pattern, but a more random pattern.
Well, thanks Ludger, I couldn't begin to explain Roz's humor........... in this she reminded me of Gracie Allen. LOL. I guess I am dating myself. Roz usually has me doubled over in laughter from her emails.
Susie on the hand has me amazed by hers. So tell me Miss Know It All........... did you really have this info stored in your brain just bursting to get out or were you typing it directly from a book? LOL
I cheated, I called my Botany professor friend. I knew that some variegation was genetic, but didn't know why.
Well thanks for doing that, now we all are smarter! At least for a little while......LOL!
I've read it twice, and it is still over my head. I am glad that we have people here who can answer these questions from others even if I can't figure it all out.
It's too early in the morning........haven't got brain in gear yet! Need more coffee, it will make sense to me as day progresses.
I got curious about pollen transmission of a virus, here is what I found. It is rare but possible. It is known that a type of avacado virus is transmitted by pollen, the fruit contains a virus when the plant itself doesn't. Tobacco streak virus is transmitted by pollen. Citrus leaf rugose virus is possibly transmitted by pollen. Virus was found in the pollen of elms for elm mottle virus.Ilarviruses in blueberries are spread by bees and infected pollen.(I found all these instances online)
The professor had told me about a plant where pollen transmitted the virus, he said the way they knew it was pollen was because the seed parent was virus free, the pollen donor was infected, the seedlings grown in sterile conditions were infected with the virus.
Susie, thanks for taking the time to do the research on the internet and for sharing the information from your Botany professor friend. I know so little about this subject and you have enlightened. Now the problem is . . how do I remember all this. I know . . I will print it out!
That is my problem Frannie......LOL.......... I have no mind left. I could print it but it would be lost within an hour. But Susie is used to my emails saying ........... tell me again PLEASE!
OK Ludger.......I pollinated my pink Vul with my friends pollen from her sick brug........... lets hope it takes!
Cala, that will explain why sometimes seedlings in an isolated GH gets the flu anyway :)
I could not find the original discussion, but got a thread refering to it. It was thought that Datura and Brugmansia was unable to carry virus within the cells of the seed, but if pollen can carry a virus ... ?

After reading this post I'm thinking that my strange seedlings are in fact variegated. Its been over a week since I posted about the patterning in the leaves of some of my seedlings. The first two sets of leaves were solid green, then a mottling pattern started to appear, next came yellow margins. Each new set of leaves have more yellow around the perimeter than the previous set.
Now if I could only get the software reloaded I could take a picture with my web cam. In the meantime I'm keeping my eye on them to see how they progress.
