text: Somitogenesis is the basis of segmentation of the mesoderm in the trunk and
tail of vertebrate embryos, Two groups of mutants with defects in this patterning
process have been isolated in our screen for zygotic mutations affecting the embryonic
development of the zebrafish (Danio rerio), In mutants of the first group, boundaries
between individual somites are invisible early on, although the paraxial mesoderm
is present, Later, irregular boundaries between somites are present, Mutations
infused somites (fss) and beamter (bea) affect all somites, whereas mutations
in deadly seven (des), after eight (aei) and white tail (wit) only affect the
more posterior somites, Mutants of all genes but wit are homozygous viable and
fertile, Skeletal stainings and the expression pattern of myoD and snail1 suggest
that anteroposterior patterning within individual somites is abnormal, In the
second group of mutants, formation of the horizontal myoseptum, which separates
the dorsal and ventral part of the myotome, is reduced, Six genes have been defined
in this group (you-type genes), yea-too mutants show the most severe phenotype;
in these the adaxial cells, muscle pioneers and the primary motoneurons are affected,
in addition to the horizontal myoseptum. The horizontal myoseptum is also missing
in mutants that lack a notochord. The similarity of the somite phenotype in mutants
lacking the notochord and in the you-type mutants suggests that the genes mutated
in these two groups are involved in a signaling pathway from the notochord, important
for patterning of the somites.
