sinapis arvensis/니코틴

Flower formation in the long-day plant Sinapis alba is strictly dependent on an inductive light treatment. Differential screening of an apex cDNA library prepared 10 days after flower induction against cDNAs from vegetative apices has identified two cDNA clones, pSFD10.35 and pSFD10.44, which

A putative family 3 glycosyl hydrolase (GH) gene showed significant differential expression in resistant Sinapis alba, compared with the susceptible Brassica juncea, as part of the initial responses during interaction with the necrotroph Alternaria brassicicola. To understand the mechanism of

Branched broomrape (Orobanche ramosa L.) is a chlorophyll-lacking, root parasitic plant that infects many crops and wild species (2). Plants are densely hairy with minute, glandular hairs, particularly on flowers and upper stems. Stems are erect, often branched just above the ground, and brown to

The genes coding for rRNAs from mustard chloroplasts were mapped within the inverted repeat regions of intact ctDNA and on ctDNA fragments cloned in pBR322. R-loop analysis and restriction endonuclease mapping show that the genes for 16S rRNA map at distances of 17 kb from the junctions of the

The nucleotide sequence of the mustard chloroplast gene for the precursor of the Mr 32,000 photosystem II protein is presented. A comparison with the corresponding genes from spinach and Nicotiana debneyi (14) reveals less than 5% nucleotide divergence in the coding region. The derived protein of

Four Methylobacterium extorquens strains were isolated from strawberry (Fragaria x ananassa cv. Elsanta) leaves, and one strain, called ME4, was tested for its ability to promote the growth of various plant seedlings. Seedling weight and shoot length of Nicotiana tabacum, Lycopersicon esculentum,

Germanium acid, a specific inhibitor of the silicic acid metabolism in diatoms, inhibits the growth of Sinapis alba, Lemna minor, Wolffia arrhiza, Nicotiana tabacum, Tradescantia spec, Zinnia elegans, and Secale cereale when applied in the same concentrations as those used in the case of diatoms

The expression of chalcone synthase (CHS) genes, which encode the first enzyme of the flavonoid pathway, is under developmental control as well as affected by external stimuli such as light. Varying fragments of the 1 kb upstream region of the CHS1 gene from white mustard (Sinapis alba L.) were

Mitochondrial (mt) DNAs from several higher-plant species (Arabidopsis thaliana, Beta vulgaris, Brassica hirta, Chenopodium album, Oenothera berteriana, Zea mays) were separated by pulsed-field gel electrophoresis (PFGE). Hybridization of the separated DNA with mtDNA-specific probes revealed an

The size and structure of mitochondrial DNA (mtDNA) molecules was investigated by conventional and pulsed-field gel electrophoresis (PFGE) and by analyzing moving pictures during electrophoresis of individual fluorescently labelled mtDNA molecules. Little or no mtDNA that migrated into the gel was
