We identify a large coiled-coil protein, Sme4/PaMe4, that is highly conserved among the large group of Sordariales and plays central roles in two temporally and functionally distinct aspects of the fungal sexual cycle: first as a component of the meiotic synaptonemal complex (SC) and then, after disappearing and reappearing, as a component of the spindle pole body (SPB). In both cases, the protein mediates spatial juxtaposition of two major structures: linkage of homolog axes through the SC and a change in the SPB from a planar to a bent conformation. Corresponding mutants exhibit defects, respectively, in SC and SPB morphogenesis, with downstream consequences for recombination and astral-microtubule nucleation plus postmeiotic nuclear migration. Sme4 is also required for reorganization of recombination complexes in which Rad51, Mer3, and Msh4 foci relocalize from an on-axis position to a between-axis (on-SC) position concomitant with SC installation. Because involved recombinosome foci represent total recombinational interactions, these dynamics are irrespective of their designation for maturation into cross-overs or noncross-overs. The defined dual roles for Sme4 in two different structures that function at distinct phases of the sexual cycle also provide more functional links and evolutionary dynamics among the nuclear envelope, SPB, and SC. meiosis | pairing | coalignment | postmeiotic division | ascomycetes

“…However, the different protein components of the respective domains (LEs, TFs and CE) exhibit great primary amino acid sequence diversities (e.g. Page and Hawley 2004;Anderson et al 2005;Bogdanov et al 2007;Bolcun-Filas and Schimenti 2012). This lack of sequence identity 7 is surprising considering a single origin of meiosis in general and, in particular, the structural conservation of the SC.…”

“…But despite these similarities, nearly all investigators stumbled across the fact that the proteins lack any detectable sequence homology and therefore any evolutionary relationship amongst the different taxa (e.g. Page and Hawley 2004;Anderson et al 2005;Bogdanov et al 2007;Bolcun-Filas and Schimenti 2012). Maybe coming along with this, the principles regulating the formation of synapsis are also quite different in mouse, flies and nematodes.…”

“…At first glance, this visible similarity leads one to appeal to the law of homologous series in autogenous variation (Vavilov, 1922). Based on its predictive abilities with respect to parallel vari ability in different taxa, this law was perceived as the "periodic table in biology" (Hammer and Schubert, 1994;Popov, 2002;Zakharov, 2005;Bogdanov et al, 2007;Yurchenko and Zakharov, 2007;Shumnyi, 2007;Trapezov, 2007;Sommer, 2008;Suslov and Kolcha nov, 2009). Despite the strong heuristic side of the law, it does not explain the cause and the evolutionary and genetic significance of the phenotypic similarity of the color aberrations in these three species.…”

The frequency of color aberrations in the seal population of Commander Islands was studied. Albino, acromelanism, nonspecific piebaldness, golden, and ferret type color phases were recorded at fre quencies about 10 -4 . They are phenotypically similar to the same phases in sable and color mutations in farm bred American mink. The evolutionary significance of color aberrations in natural populations is discussed. And then a miracle happened. From over the nearest rocky ledge a white otter swam out. Not believing my eyes, I anxiously waited for him to move just a little closer. When there were up to 20 meters to the ani mal, doubt disappeared. It really was the white sea ape, "toion," the Sea ape Prince, floating in front of me.
