    Notes: Identification of apple clonal rootstocks based on visual morphological characteristics is often difficult because of the genetic similarity of many rootstocks and the restriction of observable characteristics at the nursery stage. In this study, a total of 66 rootstock clones representing a sub-sample of a collection of apple rootstocks from different countries maintained at NIFTS, Morioka, Japan, was screened with seven simple sequence repeat (SSR) markers to establish genetic identities, estimate genetic diversity, verify parentage and examine genetic relationships. All seven SSR loci produced one or two amplified fragments and made it possible to differentiate among the rootstocks, except between virus-free subclones and their original parents as well as between ‘Aotea 40’ and ‘Aotea 106’. The parentage of all but one rootstock clone was confirmed. The placement of individual rootstock clones into subgroups in a phenogram generated from un-weighted pair group average cluster analysis was generally based on parentage or genetic origin. Based upon the ability of the SSR data to differentiate these apple rootstocks and the high level of gene diversity, it is proposed that all commercial apple rootstocks be fingerprinted to provide a mechanism to verify the identity of individual clones.

    Formation of the enveloping layer of the chum salmon egg in isotonic salt solutions (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 49 (1996), S. 0

    Topics: Biology
    Notes: After stimulation in a hypotonic solution (9.4 mOsm kg−1), inseminated eggs of the chum salmon Oncorhynchus keta initiate cleavages in isotonic salmon Ringer's solution (267.3 mOsm kg−1) containing 3.2 mM Ca2+ ions. Blastomeres of these eggs, however, separate from each other and the enveloping layer is not observed at the blastula stage. An increase in external divalent cations rescues the separation; the concentration of CaCl2 in the external medium should be 25 mM or more to induce close contact of blastomeres and the formation of an enveloping layer in isotonic salt solutions. The effectiveness of Ca2+ ions can be substituted by Mg2+, Sr2+ and Zn2+ ions; the same results are obtained in isotonic MgCl2 and SrCl2 solutions (100 mM) or in isotonic salmon Ringer's solution containing Zn ions (6.2 mM). The close contact of blastomeres and the formation of an enveloping layer are also observed in a low Ca2+ concentration (〈 0.1 mM) in a hypotonic salt solution (9.4 mOsm kg−1). The Ca2+ level in the external medium to induce the enveloping layer formation seems to be correlated with the salinity of the incubation medium. It is suggested that adhesion molecules on the surface of blastomeres in the chum salmon eggs are different in properties from those found in sea urchin and other fish species.

    Factors inducing closure of the micropylar canal in the chum salmon egg (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 42 (1993), S. 0

    Notes: The micropylar canal of the chum salmon egg was almost completely closed following egg activation caused by incubation in a hypotonic salt solution (HSS) for I h. The closure occurred in both inseminated and parthenogenetically activated eggs. Incubation of isolated envelopes from non-activated eggs in HSS or perivitelline fluid (PVF) did not induce any modification in micropylar structure, indicating that normal organization of the egg is essential for inducing closure. To reduce the volume of the perivitelline fluid, the eggs were activated in PVF or HSS containing 8 mM Dextran, Although the envelope showed hardening, closure of the micropyle was not observed in these eggs. The wall of the micropylar canal, however, possessed a slightly rough surface. Following activation in a Ca-free hypotonic salt solution with 10 mM EDTA, hardening of the egg envelope was completely inhibited. Although such eggs possessed an apparent perivitelline space, neither closure of the micropylar canal nor roughening of the canal surface were detected. We conclude that the synergistic action of perivitelline turgor pressure and perivitelline material is responsible for the closure of the micropyle.

    Closure of the micropyle during embryonic development of some pelagic fish eggs (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 40 (1992), S. 0 
    Details

    Topics: Biology
    Notes: The fine structure of the egg envelope and micropyle was studied in unfertilized and developing eggs of the flounder Paralichthys olivaceus (Temminck & Schlegel), the Alaska pollack Theragra chalcogramma (Pallas), the Japanese tilefish Branchiostegus japonicus (Houttuyn) and the porgy Pagrus major (Temminck & Schlegel). The outer envelope surface of the unfertilized egg was wrinkled, while the inner surface was folded. The micropyle of the unfertilized egg consisted of a shallow vestibule and a distinct canal. The micropylar region of the inner surface of the envelope had a conical- or bowl-shaped protrusion. In developing eggs, the thickness of the envelope decreased and showed smooth outer and inner surfaces which indicated that it had been stretched tangentially at the time of the perivitelline space formation. The lumen of the micropylar canal was invariably occupied with envelope material. We postulate that the blockage of the micropylar canal is a result of the stretching of the envelope. The closure of the micropyle inhibits sperm and external pathogens from penetrating into the perivitelline space and seems to be involved in both the permanent prevention of polyspermy and the protection of the developing embryo from bacterial infection.

    Correlation among dominance status, metabolic rate and otolith size in masu salmon (1998)

    Notes: In spatial competition between individuals, neither fish sex nor body mass affected dominance status in masu salmon Oncorhynchus masou . In contrast, resting metabolic rate (MR) was significantly correlated with dominance status, indicating that a high metabolic rate can increase the dominance rank of juvenile salmon. Whole animal growth rate was significantly correlated with MR, but not with initial body weight. This suggests that the body size of masu salmon is not a cause, but rather a consequence, of dominance status which is closely related to MR. The increment width between otolith daily rings was also significantly correlated with MR. Thus, the size of the Otolith may indicate the degree of MR.

    Notes: Abstract. A study was undertaken in 1987 to determine the prevalence of infectious panercatic necrosis virus (1PNV) infection in the lake trout population of Cornwall Lake. Alberta, Canada, and its pathogenicity to cultivable salmonid fish. Virological examination indicated that 44.4% of the adult lake trout in the lake, which is situated in a remote northern region of Alberta, were infected with the virus, mainly in the pyloric caeca and intestine. Virus was not detected in kidney, leucocytes, liver or gonads. In experimental immersion infection of brook trout fry, the virus caused a cumulative mortality of up to 74% in 30 days, beginning at 10 days post-infection. Pyloric caeca, intestine and to some extent gills were found to be early sites of viral replication. The virus was less pathogenic to rainbow trout causing a cumulative mortality of 10% and the survivors were IPNV carriers for at least 3 months. The virus did not cause mortality in young lake trout, the natural host, but the infected fish carried the virus during the experimental period of 30 days.
