Control of the migratory pathway of facial branchiomotor neurones.
Facial branchiomotor (fbm) neurones undergo a complex migration in the segmented mouse hindbrain. They are born in the basal plate of rhombomere (r) 4, migrate caudally through r5, and then dorsallyExpand

Histone H2A.Z and homologues of components of the SWR1 complex are required to control immunity in Arabidopsis.
One of the mechanisms involved in chromatin remodelling is so-called 'histone replacement'. An example of such a mechanism is the substitution of canonical H2A histone by the histone variant H2A.Z.Expand

SEF, a New Protein Required for Flowering Repression in Arabidopsis, Interacts with PIE1 and ARP61[W]
The SWR1/SRCAP complex is a chromatin-remodeling complex that has been shown to be involved in substitution of histone H2A by the histone variant H2A.Z in yeast (Saccharomyces cerevisiae) andExpand

Nitrogen availability and electron transport control the expression of glnB gene (encoding PII protein) in the cyanobacterium Synechocystis sp. PCC 6803
The glnB gene from Synechocystis sp. PCC 6803 that encodes the PII protein has been cloned by heterologous hybridization using the corresponding glnB gene from Synechococcus sp. PCC 7942. An ORF ofExpand

Nitrogen control of the glnN gene that codes for GS type III, the only glutamine synthetase in the cyanobacterium Pseudanabaena sp. PCC 6903
Pseudanabaena sp. strain PCC 6903 is the first cyanobacteria lacking the typical prokaryotic glutamine synthetase type I encoded by the glnA gene. The glnN gene product, glutamine synthetase typeExpand

Cloning and characterization of the isopenicillin N synthase gene of Streptomyces griseus NRRL 3851 and studies of expression and complementation of the cephamycin pathway in Streptomyces
A gene, pcbC, encoding the isopenicillin N synthase of Streptomyces griseus NRRL 3851, has been cloned in a 6.4-kb Bg/II DNA fragment and located in an internal 1.55-kb PvuII segment by hybridizationExpand

Determination of Cr(III) in urine, blood serum and hair using flow injection chemiluminescence analysis
Abstract A flow injection (FI) chemiluminescence method for the determination of Cr(III) in blood serum, urine and hair samples is reported. It is based on the chromium-catalyzed light emission fromExpand

Efficient plasmid transformation of the beta-lactam producer Streptomyces clavuligerus.
The conditions for optimal formation and regeneration of protoplasts of Streptomyces clavuligerus were established. The optimal temperature for regeneration of protoplasts and for transformation wasExpand

Characterization of sugar uptake in wild-type Streptomyces clavuligerus, which is impaired in glucose uptake, and in a glucose-utilizing mutant.
Wild-type Streptomyces clavuligerus NRRL 3585 is unable to utilize glucose. A glucose-utilizing (gut-1) mutant of S. clavuligerus NRRL 3585 has been obtained by N-methyl-N'-nitro-N-nitrosoguanidineExpand

Electron Transport Controls Glutamine Synthetase Activity in the Facultative Heterotrophic Cyanobacterium Synechocystis sp. PCC 6803
Glutamine synthetase (GS) from Synechocystis sp. PCC 6803 was inactivated in vivo by transferring cells from light to darkness or by incubation with the photosynthetic inhibitorExpand
