| cotton leaf curl gezira virus-satellite dnas represent a divergent, geographically isolated nile basin lineage: predictive identification of a satdna rep-binding motif. | cotton leaf curl gezira virus (clcugv), a species of the genus begomovirus (family geminiviridae), was recently cloned from cotton, okra, and sida alba plants exhibiting leaf-curling and vein-thickening symptoms in sudan. here, we describe a previously unknown lineage of single-stranded dna satellite (satdna) molecules, which are associated with clcugv, and are required for development of characteristic disease symptoms. co-inoculation of cotton and nicotiana benthamiana plants with satdnas clon ... | 2004 | 15826909 |
