Identification of mariner-like elements belonging to the cecropia subfamily in two closely related Helicoverpa species
Insect Science 18 (6), 619-628
Abstract: Mariner transposons are widespread in eukaryote genomes and have been used as transposon vectors in insect transgenesis. We examined two closely related Helicoverpa species, the cotton bollworm Helicoverpa armigera and corn earworm Helicoverpa zea, for the presence of mariner-like elements (MLEs). Multiple copies of two distinct MLEs, Hamar1 and Hamar2, were isolated in H. armigera, and a MLE showing a high degree of conservation to Hamar1 was detected in H. zea and was named Hzmar1. These MLEs belong to the cecropia subfamily, containing indels in the transposase coding region. Sequence analysis indicated the earlier invasion of Hamar1 and relatively recent activity of Hamar2.
