Abstract
The development of new molecular techniques (array CGH, M-FISH, SKY-FISH, etc.) has led to great advancements in the entire field of molecular cytogenetics. However, the application of these methods is still very limited in farm animals. In the present study, we report, for the first time, the production of 13 river buffalo (Bubalus bubalis, 2n = 50) chromosome-specific painting probes, generated via chromosome microdissection and the DOP-PCR procedure. A sequential multicolor-FISH approach is also proposed on the same slide for the rapid identification of river buffalo chromosome/arms, namely, 1p-1q, 2p-2q, 3p-3q, 4p-4q, 5p-5q, 18, X, and Y, using both conventional and late-replicating banded chromosome preparations counterstained by DAPI. The provided ‘bank’ of chromosome-specific painting probes is useful for any further cytogenetic investigation not only for the buffalo breeds, but also for other species of the family Bovidae, such as cattle, sheep, and goats, for chromosome abnormality diagnosis, and, more generally, for evolutionary studies.
