| molecular diversity of ecologically distinct mal de río cuarto virus isolates based on restriction fragment length polymorphism (rflps) and genome sequence analysis of segments 1, 7, 9 and 10. | viruses of the species mal de río cuarto virus (genus fijivirus, family reoviridae) cause significant economic losses in maize in argentina. genetic changes in the virus genome leading to better adaptation to diverse ecological conditions were postulated that would account for the increasing mrcv variability. the genomic differences between mrcv isolates from four ecologically different areas (río cuarto, rc; pergamino, p; jesús maría, jm; and tafí del valle, tv) were studied. rt-pcr-amplified f ... | 2007 | 17370108 |
