Most of the 400 RNA editing sites in flowering plant mitochondria are found in mRNAs. Consequently, the sequence vicinities ofhomologous sites are highly conserved between different species and are presumably recognized by likewise conserved trans-factors. To investigate the evolutionary adaptation to sequence variation, we have now analyzed the recognition elements of anediting sit...

Cauliflower (Brassica oleracea var. botrytis) and broccoli (B. oleracea var. italica) differ in the developmental stage of the reproductive meristem at harvest. A cauliflower head is formed by arrest at the inflorescence meristem stage and broccoli at the flower bud stage, and the horticultural value of the crop depends on synchronous development across the head. In other plant species, gibbere...

cauliflower-like nanostructure of cadmium oxide was synthesized by utilizing mechanochemical reaction followed calcination procedure for the first time. the design of experiment (doe) by taguchi method was used to study influence of the chosen factors and to consider optimum conditions of the experiments. the temperature of calcining, the duration of milling, the duration of calcining and react...

Studies on the diversity within and among cabbage (Brassica oleracea L. var. capitata L.), cauliflower botrytis), Chinese rapa ssp. pekinensis) variants are essential for development of healthy diets. However, most studies them have been limited to a single species, with little integrated analysis between them. In this study, these species varieties is assessed by determining contents 15 major ...

The evolution of plant morphologies during domestication events provides clues to the origin of crop species and the evolutionary genetics of structural diversification. The CAULIFLOWER gene, a floral regulatory locus, has been implicated in the cauliflower phenotype in both Arabidopsis thaliana and Brassica oleracea. Molecular population genetic analysis indicates that alleles carrying a nonse...

Development of the cauliflower phenotype in Arabidopsis thaliana requires mutations at both the CAULIFLOWER and APETALA1 loci. BoAP1 is the Brassica oleracea orthologue to the Arabidopsis AP1 gene, and is present in two copies in Brassica genomes. The BoAP1-A gene appears to encode a full-length protein, but BoAP1-B alleles in B. oleracea contain insertions that lead to premature translation te...

Previous studies have indicated that the vacuole represents the major inositol 1,4,5-trisphosphate (InsP3)-mobilizable Ca2+ pool in higher plants. This findings is in contrast to animal cells, in which the endoplasmic reticulum and plasma membrane constitute the dominant InsP3-sensitive membranes. We used membrane vesicles prepared from cauliflower (Brassica oleracae L.) inflorescences that wer...

A water-soluble chlorophyll protein (WSCP) in cauliflower (Brassica oleracea L.) was purified and its N-terminal sequence was determined. Forty-six of 48 residues of the sequence completely matched those of the drought-induced 22-kD protein (BnD22) in rapeseed (Brassica napus L.). All 40 sequenced residues of WSCP from rapeseed were perfectly matched to those of BnD22. Thus, WSCP may be identic...

The microbiological quality of blanched frozen cauliflower, cut corn, and peas at the retail level was determined. At 35 degrees C, mean aerobic plate count (APC) values for cauliflower, corn, and peas, respectively, were 30,000, 6,100, and 4,700 per g; at 30 degrees C, the mean APC values were 45,000, 8,500, and 6,800 per g, respectively. Geometric means for coliform, Escherichia coli, and Sta...
