A locust type 1 ADP-ribosylation factor (lARF1)* is 100% identical in amino acid sequence to Drosophila ARF1 despite obvious DNA sequence divergence.
The cDNA of a type 1 ADP-ribosylation factor (ARF) from the desert locust, Locusta migratoria was cloned, sequenced and compared to ARF1 genes of other species. The locust ARF1 protein is 100% identical with the ARF1 protein of the fruit fly Drosophila melanogaster even though the DNA sequences are only 79% identical. The significance of this finding in relation to the considerable evolutionary distance between hemimetabolous and holometabolous insects is discussed.
