1. Low-temperature scanning electron microscope observations of the Meloidogyne incognita egg mass: the gelatinous matrix and embryo development

Author:
Orion, D.; Wergin, W.P.; Chitwood, D.J.; Erbe, E.F.

Journal of nematology 1994 v.26 no.4 pp. 402
ISSN:
0022-300X
Subject:
Meloidogyne incognita; plant parasitic nematodes; ova; embryogenesis; ultrastructure
Abstract:
... The root-knot nematode Meloidogyne incognita was cultured monoxenically on excised tomato roots. Galls and egg masses were observed daily using a light microscope. Two phases were distinguished in the gelatinous matrix of the egg mass: a translucent, amorphous material on the surface of the egg mass and a denser, layered phase in which nematode eggs were deposited. Egg masses were also cryofixed, ...

Abstract:
... A cDNA encoding a putative cytoplasmic ribosomal protein LS from alfalfa (MsRL5), the first sequence from higher plants, has been characterized. The derived amino acid sequence of 181 residues contains the L5 signature, is 72.2% identical to yeast ribosomal L5 and shares high identity with other RL5 peptides from eukaryotic origin. The sequence does not contain any signal or transit peptide and th ...

Abstract:
... The potato tuber moth is susceptible to at least three insecticidal crystal proteins (ICPs) from Bacillus thuringiensis: CryIA(b), CryIB, and CryIC. To design useful combinations of toxin genes either in transgenic plants or in new genetically modified B. thuringiensis strains, it is necessary to determine the binding characteristics of the different ICPs so as not to combine a pair sharing the sa ...

Abstract:
... Octopamine and 5-hydroxytryptamine (5-HT) were previously/shown to affect phagocytosis in cockroach hemocytes through unidentified receptor-mediated events. In the present study, we examined the ability of 5-HT and octopamine to enhance inositol trisphosphate (IP3) production using hemocyte membranes of the American cockroach, Periplaneta americana. Octopamine enhanced IP3 production with a maxima ...

Abstract:
... Four double-stranded RNA (dsRNA) molecules were isolated from Phaffia rhodozyma UCD 67-385. Their molecular sizes were approximately 4.3, 3.1, 0.9 and 0.75 kilobase pairs (kbp) as determined by agarose-gel electrophoresis and they were designated as L, M, S1 and S2, respectively. By differential centrifugation in sucrose gradients, these dsRNAs copurified with isometric virus-like particles 36 nm ...

Abstract:
... A multidrug resistance gene, YDR1, of Saccharomyces cerevisiae, which encodes a 170-kDa protein of a member of the ABC superfamily, was identified. Disruption of YDR1 resulted in hypersensitivity to cycloheximide, cerulenin, compactin, staurosporine and fluphenazine, indicating that YDR1 is an important determinant of cross resistance to apparently-unrelated drugs. The Ydr1 protein bears the highe ...

Abstract:
... Byp1-3 is an amber nonsense allele of the Saccharomyces cerevisiae GGS1/TPS1 gene which encodes the small subunit of the trehalose synthase complex. Mutations in this gene confer an inability to grow on glucose or fructose but the phenotype of byp1-3 mutants is leaky in a strain-dependent manner. Overexpression of the isolated byp1-3 allele suppressed the growth defect of a ggS1/tps1 delta mutant. ...

Abstract:
... MRS6 is a newly-identified gene in the yeast Saccharomyces cerevisiae. Its product Mrs6p shows significant homology to the mammalian GDP dissociation inhibitor (GDI) of Rab/Ypt-type small G proteins and to the human choroideraemia protein (CHM), the component A of Rab-specific GGTase II. The interaction of Mrs6p with G proteins is indicated by our observation that the MRS6 gene suppresses the effe ...

Abstract:
... The Kluyveromyces linear plasmids pGKL1 and pGKL2, encoding killer activity, were efficiently cured by UV irradiation. This event was investigated in more detail by the use of the terminal protein (TP)-associated cytoplasmic linear plasmids, pJKL1 and pRKL2, with a selectable marker LEU2. This observation was compared with the UV effect on the nuclear plasmids pLS1 (telomere-associated linear form ...
