Closely related species have often evolved dramatic differences in body
size. Takifugu rubripes (fugu) is a large marine pufferfish whose genome
has been sequenced, whereas T. niphobles is the smallest species among
Takifugu. We show that, unsurprisingly, the juvenile growth rate of T.
rubripes is higher than that of T. niphobles in a laboratory setting. We
produced F2 progenies of their F1 hybrids and found one quantitative trait
locus (QTL) significantly associated with variation in juvenile body size.
This QTL region (3.5 Mb) contains no known genes directly related to
growth phenotype (such as IGFs) except Fgf21, which inhibits growth
hormone signaling in mouse. The QTL in Takifugu spp. is distinct from the
region previously known to control body size variations in stickleback or
tilapia. Our results suggest that in the fish tested herein, genomic
regions underlying body size evolution might have different genetic
origins. They also suggest that many diverse traits in Takifugu spp. are
amenable to genetic mapping.
