Juvenile hormones inhibit murine cell cycle progression and expression of type c viruses

Juvenile hormones (JH), congeners of retinoic acid, were examined for their capacity to inhibit cell cycle progression and chemically induced expression of endogenous xenotropic retrovirus in Kirsten sarcoma v...

Expression of the ribosomal DNA insertions in bobbed mutants of Drosophila melanogaster

We have shown earlier that interrupted rRNA genes in Drosophila melanogaster do not contribute significantly to rRNA production by a splicing mechanism (Long and Dawid 1979). In the work reported here the express...

The elimination of potato viruses X, Y, S and M in meristem and explant cultures of potato in the presence of Virazole

Incorporation of Virazole into potato explant and meristem culture media results in a higher percentage of virus-free progeny plants from virus-infected explant and meristem donor plants than are produced in t...

Amino acid analogs inhibit murine xenotropic retrovirus expression and cell cycle progression

Certain functional analogs of amino acids were examined for their capacity to inhibit chemically induced expression of endogenous xenotropic retrovirus from Kirsten sarcoma virus transformed BALB/c (K-BALB) mo...

Induction of endogenous xenotropic retrovirus expression by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate

The tumor promotor 12-O-tetradecanoylphorbol-13-acetate (TPA) was examined for its ability to induce endogenous retrovirus from a high-passage clone of Kirsten sarcoma virus-transformed Balb/c (K-Balb) mouse cell...

Regulation of the fdhF gene encoding the selenopolypeptide for benzyl viologen-linked formate dehydrogenase in Escherichia coli

Two classes of mutants defective in benzyl viologen-linked formate dehydrogenase (FDH-BV) activity were isolated from Escherichia coli K12. Class I consisted of four mutants which were specifically devoid of FDH-...

Catecholamines induce metamorphosis in the hydrozoan Halocordyle disticha but not in Hydractinia echinata

Planula larvae of the marine hydroids Halocordyle disticha and Hydractinia echinata were treated with the catecholamines epinephrine, norepinephrine and dopamine, as well as with certain of their precursors and a...

High plating efficiency and plant regeneration frequency in low density protoplast cultures derived from an embryogenic Brassica napus cell suspension

Protoplasts were isolated from an embryogenic cell suspension culture derived from microspores of Brassica napus cv. Jet Neuf. Protoplast yield varied with the cell suspension growth medium. Optimization of proto...

The phylogenetic position of taxaceae based on 18S rRNA sequences

The evolutionary position of the yew family, Taxaceae, has been very controversial. Some plant taxonomists strongly advocate excluding Taxaceae from the conifer order and raising its taxonomic status to a new ...

Analysis of the frequency of inheritance of transposed Ds elements in Arabidopsis after activation by a CaMV 35S promoter fusion to the Ac transposase gene

The Ac/Ds transposon system of maize shows low activity in Arabidopsis. However, fusion of the CaMV 35S promoter to the transposase gene (35S::TPase) increases the abundance of the single Ac mRNA encoded by Ac an...

Acclimation of photosynthetic proteins to rising atmospheric CO₂

In this review we discuss how the photosynthetic apparatus, particularly Rubisco, acclimates to rising atmospheric CO₂ concentrations (c_a). Elevated c_a alters the control exerted by different enzymes of the Calvi...
