| cotton leaf curl gezira alphasatellite associated with tomato leaf curl sudan virus approaches the expected upper size limit in the evolution of alphasatellites. | begomoviruses (family geminiviridae) cause severe damage to tomato crops worldwide. among them, tomato leaf curl disease (tolcd)-associated begomoviruses are a major concern for tomato production in sudan. here, we report the detection of unexpectedly large cotton leaf curl gezira alphasatellite molecules (up to 1467 nt) associated with an isolate of a novel strain of tomato leaf curl sudan virus (tolcsdv) in tomato plants affected by tolcd. a recombinant nature is suggested for this tolcsdv iso ... | 2013 | 24140627 |
