Before revision: Dd1 (Desulfovibriondesulfuricans) D. desulfuricans is a soil bacterium in the deltaproteobacteria; Dd1 packages 13.6 kb DNA fragments VTA (Methanococcus voltae) M. voltae is an archaean; its GTA is known to transfer 4.4 kb DNA fragments but has not been otherwise characterized
After revision: , although a defective provirus related to Methanococcus head-tailed viruses (Caudoviricetes) in M. voltae A3 genome has been suggested to represent the GTA locusDd1 (Desulfovibriondesulfuricans) D. desulfuricans is a soil bacterium in the deltaproteobacteria; Dd1 packages 13.6 kb DNA fragments VTA (Methanococcus voltae) M. voltae is an archaean; its GTA is known to transfer 4.4 kb DNA fragments but has not been otherwise characterized
