Re: Is this true and typical BSV?
Yes, one of the Mysores in the photos by Dombo has BSV.

Re: Is this true and typical BSV?
Thank you very much for the pictures and clarification Gabe! :)
Comparing your pictures to my ''Mysore'',the bleaching pattern on the leafs is identical unfortunately...What would you suggest me do? Mark, Its true that the integrated form of BSV cannot be spread without breeding but once a plant expresses the virus,as its clear it does when it shows symptoms,BSV can be transmitted by its mealybug vectors and these arent rare unfortunately. I will be waiting on Gabe to call it but what i am afraid we should do to protect the rest of our bananas is trash the infected plants as the chance of them curing themselves and confining the virus to just its integrated form,is very small and we cant count on it,although it does can happen. Then we need to find a healthy ''Mysore''......... Mitchel's Pisang Klotek doesnt seem to be expressing the virus. |

The species in Mysore is Banana steak Mysore virus. Other identified species include Banana streak Goldfinger virus, and Banana steak Obino l'Ewai virus. They just refer to on which cultivars they were first identified. BSV is associated with M. balbisiana genomes, but there are also other similar viruses in all M. acuminata. It is just a matter of whether or not those sequences are expressed to create the virus. Once the virus is created, it is active. There are many cases of these virus sequences integrated into plants, but only very few cases, as in banana, where it is infectious and causes disease. There are still many unknowns about the virus because it is a rather rare situation. |

Thank you very much for your reply Gabe! :)
I guess we need to trash them,as hard as this is... |
