  • Title: Cotton leaf curl Gezira alphasatellite associated with tomato leaf curl Sudan virus approaches the expected upper size limit in the evolution of alphasatellites.

    Abstract:
    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 isolate.
