    Notes: Abstract  We have constructed a sex-averaged genetic linkage map in coastal Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var ‘menziesii’) using a three-generation outcrossed pedigree and molecular markers. Our research objectives are to learn about genome organization and to identify markers associated with adaptive traits. The map reported here is comprised of 141 markers organized into 17 linkage groups and covers 1,062 centiMorgans (cM). Of the markers positioned on the map, 94 were derived from a Douglas-fir complimentary-DNA (cDNA) library that was constructed from new-growth needle tissue. Other markers include 11 Douglas-fir genomic-DNAs, 20 loblolly pine (Pinus taeda L.) cDNAs, 15 random amplified polymorphic DNAs (RAPDs) and a PCR-amplified phytochrome probe. A high degree of variation was detected in each of the two parents of our mapping population, and many of the restriction fragment length polymorphism (RFLP) and RAPD phenotypes were complex. Marker data were analyzed for linkage using mapping software JOINMAP version 2.0.

    Notes: Abstract  The lack of red-purple pigmentation in seedlings obtained from crosses between M. cv Baskatong, carrying a dominant homozygous gene for red-purple pigmentation, and other species has been used for the detection of apomictic plants in Malus species. RAPD marker techniques were employed to evaluate the genetic similarity between putative apomictic seedlings and their female parents. From the selected set of 20 (OPA) primers about half were able to detect hybrids from the apomictic seedlings, if present. RAPD analyses confirmed the usefulness of the colour-marker gene in detecting the hybrids in vitro for seedlings of M. toringoides×M. cv Baskatong, but not for crosses involving M. hupehensis×M. cv Baskatong where in vitro colour-based selection was not possible (due to red stems in all cases). The set of primers (OPA-01, 02, 08, 09, 10, 12, 13, 14, 16, 18 and 20) clearly determined the hybrid nature of seedlings and allowed the selection of apomictic ones. Therefore, although cv Baskatong is useful as an indicator, these data show that this technique is not applicable in all cases.

    Notes: Abstract A genetic linkage map for radiata pine (Pinus radiata D. Don) has been constructed using segregation data from a three-generation outbred pedigree. A total of 208 loci were analyzed including 165 restriction fragment length polymorphism (RFLP), 41 random amplified polymorphic DNA (RAPD) and 2 microsatellite markers. The markers were assembled into 22 linkage groups of 2 or more loci and covered a total distance of 1382 cM. Thirteen loci were unlinked to any other marker. Of the RFLP loci that were mapped, 93 were detected by loblolly pine (P. taeda L.) cDNA probes that had been previously mapped or evaluated in that species. The remaining 72 RFLP loci were detected by radiata pine probes from a PstI genomic DNA library. Two hundred and eighty RAPD primers were evaluated, and 41 loci which were segregating in a 1∶1 ratio were mapped. Two microsatellite markers were also placed on the map. This map and the markers derived from it will have wide applicability to genetic studies in P. radiata and other pine species.

    Notes: Abstract   We evaluated chloroplast DNA (cpDNA), isozymes, single to low-copy nuclear DNA (RFLPs), and random amplified polymorphic DNAs (RAPDs) in terms of concordance for genetic distance of 15 accessions each of Solanum etuberosum and S. palustre, and 4 accessions of S. fernandezianum. These self-compatible, diploid (2n=24), and morphologically very similar taxa constitute all species in Solanum sect. Etuberosum, a group of non-tuber-bearing species closely related to Solanum sect. Petota (the potato and its wild relatives). Genetic distance and multidimentional scaling results show general concordance of isozymes, RFLPs and RAPDs between all three taxa; cpDNA shows S. etuberosum and S. palustre to be more similar to each other than to S. fernandezianum. Interspecific sampling variance shows a gradation of resolution from allozyme (low) to RAPD to RFLP (high); while intraspecific comparisons graded from RFLPs (low) to RAPDs (high; lack of sufficient allozyme variability within species precluded comparisons for allozymes). Experimental error was low in RFLPs and RAPDs.

    Notes: Abstract The Sw-5 locus confers dominant resistance to tomato spotted wilt virus (TSWV). To map the location and facilitate the identification of markers linked to Sw-5 we developed a pair of near-isogenic lines (NILs) and an F2 Lycopersicon esculentum x L. pennellii population segregating for resistance to TSWV. DNA from the NILs was analyzed using 748 random 10-mer oligonucleotides to discern linked molecular markers using a random amplified polymorphic DNA (RAPD) approach. One random primer (GAGCACGGGA) was found to produce a RAPD band of about 2200 bp that demonstrates linkage to Sw-5. Data from co-segregation of resistance and restriction fragment length polymorphisms (RFLPs) in a F2 interspecific population position Sw-5 between the markers CT71 and CT220 near the telomere of the long arm of chromosome 9.

    Notes: Abstract. An antibody raised against a peptide based on the C-terminal derived amino acid sequence from a cloned Drosophila melanogaster (fruit fly) gene, Rdl (resistant to dieldrin), was used to investigate localization of a GABA receptor subunit in adult male D. melanogaster. Many regions in the brain and thoracic ganglia were stained with this antibody. For example, staining was detected in the medulla, lobula and lobular plate optic neurpiles. Also stained were the antennal lobe glomeruli, the ellipsoid body of the central complex and the mushroom bodies. These results suggest possible roles for an RDL-like GABA receptor subunit in the processing of olfactory, visual and mechanosensory information in the nervous system of D. melanogaster.

    Notes: Abstract  Neuropeptides with similarities to vertebrate tachykinins, designated tachykinin-related peptides (TRPs), have been identified in several insect species. In this investigation we have utilized an antiserum raised to one of the locust TRPs, locustatachykinin-I (LomTK-I), to determine the distribution pattern of LomTK-like immunoreactive (LTKLI) neurons in the developing nervous system of the moth Spodoptera litura. A number of LTKLI neurons could be followed from the larval to the adult nervous system: a set of median neurosecretory cells (MNCs) in the brain, a pair of brain descending neurons and a few sets on neurons in the ventral nerve cord. The distribution of LTKLI neurons in the adult brain is very similar to that seen in other insect species with prominent arborizations in the central body, antennal lobes, mushroom body calyces, optic lobe neuropils and other distinct neuropil areas in the protocerebrum and tritocerebrum. A new finding is the presence of LTKLI neurosecretory cells with axon terminals in the anterior aorta and corpora cardiaca, suggesting for the first time a neurohormonal role of tachykinin-related peptide(s) in insects. During postembryonic development the number of LTKLI neurons in the ventral nerve cord decreases somewhat, whereas the number increases in the brain. Thus the functional roles of TRPs may change to some extent during development.

    Localization of the 110 kDa receptor for laminin in brains of embryonic and postnatal mice (1995)

    Notes: Abstract Laminin, a large glycoprotein of the basement membrane that promotes the growth of nerve cell processes in vitro has also been detected in the brains of developing embryos in situ where it is postulated to promote or guide neural outgrowth. We have investigated the histological and developmental patterns of a receptor to a specific pentapeptide sequence in the A chain of the laminin molecule (PA22-2 or IKVAV) that has been identified as a neuron growth-promoting sequence. Standard immunocytochemical procedures were used to localize the receptor by means of a polyclonal antibody to affinity-purified receptor (MR=110 kDa) from mouse brains. Results for postnatal stages (P) stages (P 1,7,8,25,30,and adult) show that the 110 kDa receptor is localized in fibers in the cortex and hippocampus, in astroglial cells at the surface of the cortex, and in neuronal cell bodies in the hippocampus. In contrast, the A-chain ligand is localized in cell bodies in the same regions at P stages. For embryonic stages (E) (E 14 and E 16) the receptor is localized in bundles of fibers in the superficial and deep cortical layers, and in cell bodies in these regions at E 14 only. Staining for the A chain ligand of the receptor was first seen postnatally. We speculate that the inverse histological pattern of receptor and ligand with respect to cell bodies and fibers may reflect a role in controlling axon guidance during development or repair during regeneration.
