从喀麦隆秋葵和海葵属植物(锦葵科)中分离到两个与海棠病毒相关的α卫星。侵染秋葵和苹果星的α卫星的全核苷酸序列分别为1375和1416-1418个核苷酸，两者都具有其他α卫星的特征。根据序列比对，这些以前未被描述的Alphasatellite是Colecusatellite属和Gosmusatellite属中不同的成员，并已分别暂定为“辣椒黄脉马里Alphasatelle3”和“棉花卷叶Gezira Alphasatelle3”。结合以前的研究，喀麦隆特有的阿尔法卫星菌似乎更加多样化，感染的植物种类和科比目前认识的要多得多。
Two begomovirus-associated alphasatellites were isolated from okra and a malvastrum plant (Malvaceae) in Cameroon. The complete nucleotide sequences of the okra- and malvastrum-infecting alphasatellites were 1375 and 1416–1418 nucleotides, respectively, and both exhibited features characteristic of other alphasatellites. Based on pairwise sequence comparisons, these previously undescribed alphasatellites are members of distinct species in the generaColecusatelliteandGosmusatelliteand have been tentatively named “pepper yellow vein Mali alphasatellite” and “cotton leaf curl Gezira alphasatellite3”, respectively. Taken together with previous studies, alphasatellites endemic to Cameroon appear to be more diverse and infect plants of many more species and families than currently recognized.
