A novel male-associated marker for sex identification in Ussuri catfish Pseudobagrus ussuriensis
摘要
Abstract
The Ussuri catfish
Pseudobagrus ussuriensis
is a promising aquaculture fish with sexual dimorphism that males grow 2-3 times faster than females. Therefore
all-male breeding could increase production of this fish
and sex-linked markers would be useful during the breeding process. In this study
a male-associated marker named
PuGT54
was isolated in
P. ussuriensis
from a previously constructed microsatellite library. A total of 185
P. ussuriensis
individuals containing 95 females and 90 males were used to test the usage of this maker. And results showed that sexes of all individuals were successfully identified
indicating the high reliability and accuracy of this marker for sex identification. Furthermore
the male-specific fragment amplified by this maker was cloned and sequenced
which was 118 base pairs in length. As homologous genes of this fragment was not found through BLASTn
detailed information of the male-specific fragment is unknown presently. Nevertheless
this marker would be helpful in conservation
breeding and ecological study of
P. ussuriensis
.
