Plant viruses have their own way for movement and dispersal. The necessary encounters between patogens and their hosts are due to movement of patogen or host, or a combination of the two. Few plant viruses can survive for long away from their hosts. Therefore, limited opportunities exist for plant viruses to spread and become established within plant communities without the assistance of vectors. In this review, important means of dispersal of plant viruses have been examined with examples.

Bitki Viruslarının Yayılışları ve Taşınması

Öz

Bitkilerde hastalık oluşturan viruslar, kendilerine özgü olan yayılma ve taşınma yollarına sahiptirler. Patojen ile konukçusunun bir araya gelebilmesi için, her ikisinden birisinin hareket edebilme özelliğinin olması zorunludur. Bitki viruslarından çok azı konukçularından ayrı olarak canlılıklarını devam ettirebilmektedir. Bu nedenle, bazı yayılma ve taşınma yollarının yardımı olmaksızın, virusların bitki topluluklarına ulaşmaları ve yerleşebilmeleri için sınırlı imkanlar mevcuttur. Bu makalede, bitki viruslarının yayılma ve taşınma yönünden yaygın olarak kullandıkları yollar, örnekler verilerek incelenmiştir.
