title: Deletions in the KTER-encoding domain, which is needed for Polymyxa transmission, in manually transmitted isolates of Beet necrotic yellow vein benyvirus.
abstract: One A and one B type isolate of Beet necrotic yellow vein benyvirus which had been passaged for more than 15 years on manually inoculated Chenopodium quinoa in our laboratory were found to have small deletions in the KTER-encoding domain on RNA 2 which is necessary for Polymyxa transmission. There were no indications that these isolates and a third one, in which intact RNA 2 was detected, contained mixtures of deleted and intact RNAs or that populations of RNAs 2 with different deletions including very large ones were present.
