(n.) A genus of plants embracing several species and varieties differing much in appearance and qualities: such as the common cabbage (B. oleracea), broccoli, cauliflowers, etc.; the wild turnip (B. campestris); the common turnip (B. rapa); the rape or coleseed (B. napus), etc.
Example Sentences:
(1) Thus, although the genes involved in self-incompatibility in Brassica and Nicotiana are not homologous in their coding regions, signals for expression of these genes are apparently conserved between the two genera.
(2) A cDNA clone encoding a Brassica napus drought-induced 22 kDa (BnD22) protein has been isolated and characterized.
(3) The coding sequence of both B. napus genes are highly homologous (96% and 93% respectively) to a Brassica campestris ACP cDNA sequence, suggesting that they may have evolved from this ancestral gene.
(4) This is the first study in which an attempt has been made to define the inducing compounds in Brassica vegetables by feeding the individual purified glucosinolates.
(5) The sequence is reported of a cDNA molecule homologous to an mRNA from stigma tissue of Brassica oleracea plants homozygous for the S5 self-incompatibility allele.
(6) In both studies the mean plasma half-life of caffeine was reduced by approximately 20% following a Brassica diet, suggesting that Brassica vegetables stimulate caffeine metabolism.
(7) No binding with either toxin form could be observed with hemocytes of P. brassicae.
(8) The two Brassica species and R. sativa contain roughly equal amounts (12-14 kb) of cpDNA sequences integrated within their 208-242 kb mtDNAs.
(9) This would suggest that the duplications which gave rise to the different members occurred independently in the two groups of species after separation of Arabidopsis from the Brassica lineage.
(10) Antibodies were raised against the major seed apolipoproteins of Brassica napus, Sinapis alba and Raphanus sativum.
(11) Both protoxin and activated toxin bound to primary midgut cell cultures of Pieris brassicae larvae as well as to cells of an established culture of Drosophila melanogaster.
(12) The presence of a fragment of polyA resistant to both T1 and p ribonucleases in mRNAs extracted from wing imaginal disks of an insect, Pieris brassicae, is reported.
(13) The successful transfer of a marker gene (hpt gene) from Brassica nigra into B. napus via direct gene transfer was demonstrated.
(14) In ligand blotting experiments the toxin bound proteins of 120 kDa in M. sexta, 125 kDa in P. brassicae and numerous proteins in H. zea.
(15) Levels of indolylglucosinolates in Brassica vegetables correlated significantly with the amounts of N-nitroso compounds formed in these vegetables after nitrite treatment.
(16) An ATP-independent DNA topoisomerase has been isolated from chloroplasts of cauliflower leaves (Brassica oleracea var.
(17) These results show the development in the rhizosphere of Brassica campestris of a very active microbiological process of insoluble phosphorus mineral compounds dissolution; thus, the growing of Brassica may be expected to raise the phosphorous fertility level of the soil.
(18) Adenine phosphoribosyltransferase was purified from Brassica juncea leaves approximately 4000-fold, to homogeneity.
(19) When fused to napin regulatory sequences, the exotoxin gene specifically arrested embryo development in the seeds of transgenic Brassica napus plants concomitant with the onset of napin expression.
(20) Sequence analysis of the Ogura-specific mitochondrial DNA (mtDNA) fragment isolated previously from Brassica cybrids carrying Ogura cytoplasmic male sterility (cms) revealed a tRNA(fMet) sequence, a putative 138 amino acid open reading frame (orf138), and a 158 amino acid ORF (orf158) previously observed in mitochondrial genomes from several other plant species.

Definition:
(n.) A variety of cabbage in which the leaves never form a compact head.
(n.) Any white cabbage before the head has become firm.
