Maternal Gene

Axis formation in fish and amphibians is initiated by a prepattern of maternal gene products in the blastula. The embryogenesis of annual killifish challenges prepatterning models because blastomeres disperse and then re-aggregate to form the germ layers and body axes. This dispersion-aggregation process prompts the question how axis determinants such as Huluwa and germ layer inducers such as Nodal function in annual killifish. Here we show in Nothobranchius furzeri that huluwa, the factor thought to break symmetry by stabilizing β-catenin, is a non-functional pseudogene. Nuclear β-catenin is not selectively stabilized on one side of the blastula but accumulates in cells forming the incipient aggregate. Inhibition of Nodal signaling blocks aggregation and disrupts coordinated cell migration, establishing a novel role for this signaling pathway. These results reveal a surprising departure from classic mechanisms of axis formation: canonical Huluwa-mediated prepatterning is dispensable and Nodal coordinates morphogenesis.

A New Species

Nothobranchius kadleci, a new African annual killifish species, is described from the drainages of the Save, Gorongose, Pungwe and Zangue Rivers in the Sofala Province of central Mozambique. Nothobranchius kadleci is similar to Nothobranchius furzeri from which it is distinguished by colouration (red pelvic fins, red lips, more extensive red colouration on body) and morphology (larger distance between pectoral and pelvic fins, shorter anal and dorsal fins, and shorter base of the anal fin). The currently known distribution of these two species is allopatric, with the N. kadleci range north of the N. furzeri range. Nothobranchius kadleci occurs sympatrically with Nothobranchius orthonotus and Nothobranchius rachovii, from which it can clearly be distinguished by different colour patterns of the fins and body, head shape and morphometric characteristics. A total of 12 populations were recorded between the northern bank of the Save River and southern bank of the Zambezi during collection trips in February 2008 and February 2009.

Genetic Mechanisms

Diapause and aging are controlled by overlapping genetic mechanisms in C.elegans and these include microRNAs (miRNAs). Here, we investigated miRNA regulation in embryos of annual killifish that naturally undergo diapause to overcome desiccation of their habitats. We compared miRNA expression in diapausing and non-diapausing embryos in three independent lineages of killifish. We identified 13 miRNAs with similar regulation in all three lineages. One of these is miR-430, which is known as key regulator of early embryonic development in fish. We further tested whether this regulation overlaps with the aging-dependent regulation of miRNAs in one annual species: Nothobranchius furzeri. We found that miR-101a and miR-18a are regulated in the same direction during diapause and aging. These results provide the first evidence that overlapping genetic networks control diapause and aging in vertebrates and suggest that diapause mimics aging to some extent
