The Role of Lichens in the Structure, Productivity, and Mineral Cycling of the Wet Coastal Alaskan Tundra
Lichens are a constant, though variable, component of arctic tundra ecosystems (Wielgolaski, 1972, 1975). In the Barrow tundra lichens have been reported as a minor part of the vegetation (Britton, 1967; Spetz...

Resistance of Brain Tumours to Chemotherapy: Preliminary Studies of Rat and Human Tumours
There are several possible reasons why malignant brain tumours do not respond to chemotherapy. First, because of impaired drug delivery, chemotherapeutic agents might not reach all tumour cells in cytoxic conc...

The production of callus capable of plant regeneration from immature embryos of numerous Zea mays genotypes
In the summer of 1983, immature embryos from 101 selfed inbred lines and germplasm stocks of Zea mays L. were examined for their ability to produce callus cultures capable of plant regeneration (regenerable cultu...

Continuous Production of a Novel Lysozyme via Secretion from the Yeast, Pichia pastoris
We have cloned a cDNA for bovine lysozyme c2, a novel lysozyme characteristic of the cow stomach and expressed its protein product by secretion using its native signal sequence in the methylotrophic yeast, Pichia...

Somaclonal variation in a maize inbred line is not associated with changes in the number or location of Ac-homologous sequences
Somaclonal variation (tissue culture-induced mutations) may result, in some instances, from the activation of transposable elements. This study was conducted to determine whether somaclonal variants in the Zea ma...

Assignment of human genes for β2 and β4 subunits of voltage-dependent Ca2+ channels to chromosomes 10p12 and 2q22-q23
We have used human β2 and β4 cDNA probes to map the genes encoding two isoforms of the regulatory β subunit of voltage-activated Ca2+ channels, viz. CACNB2 (β2) and CACNB4 (β4), to human chromosomes 10p12 and 2q...
