Time point of virus yellows infection is crucial for yield losses in sugar beet, and co‐infection with beet mosaic virus is negligible under field conditions

open access: yesPlant Pathology, Volume 73, Issue 8, Page 2056-2070, October 2024.
Early virus yellows infections cause significant yield loss in sugar beet while late infections do not. Beet mosaic virus alone does not cause significant yield losses; only in co‐infection with beet mild yellowing virus (BMYV), losses exceed those from single BMYV infection.

Μοριακός χαρακτηρισμός, μελέτη των εξελικτικών σχέσεων και ανίχνευση ιών της οικογένειας Closteroviridae που σχετίζονται με την ασθένεια μικροκαρπίας της κερασιάς [PDF]

open access: yes, 2021
Στόχος της παρούσας εργασίας ήταν η διερεύνηση της παρουσίας της ασθένειας της μικροκαρπίας της κερασιάς (LChD) στην Ελλάδα και ο χαρακτηρισμός των ιών που σχετίζονται με αυτήν. Για το σκοπό αυτό πραγματοποιήθηκε επισκόπηση οπωρώνων κερασιάς και άλλων ειδών πυρηνοκάρπων για την παρουσία των Little cherry virus 1 και -2 (LChV-1 και -2).
