These sequences were compared with that published for a Tanzanian isolate (-T, 2801 nt) and the partial sequence of athird Malawian isolate. Intergenic region sequences of all isolates, and deduced amino acid sequences of their AC1 (Rep) proteins, each formed a tightly related cluster that was distinct from the comparable components of other begomoviruses. Other complementary-sense genes (AC2, AC3, AC4) differed between EACMV isolates in a way consistent with the accumulation of point mutations. In contrast, virus-sense genes (CP, AV2) of isolates -MH and -MK differed (substantially for AV2) from those of other EACMV isolates but somewhat resembled those of tomato yellow leaf curl virus - Israel, suggesting they had been acquired by recombination with an unidentified begomovirus., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-79-11-2835
