| anaerobically digested poultry slaughterhouse wastes as fertiliser in agriculture. | chemical and physical analysis, 27-d plant growth assays with carrot (daucus carota) and chinese cabbage (brassica campestris var. chinensis), and 5-d phytotoxicity assays with chinese cabbage and perennial ryegrass (lolium perenne) were used to investigate the suitability of anaerobically digested poultry slaughterhouse waste for fertiliser in agriculture and the effect of aerobic post-treatment on the properties of the digested material. the digested material appeared to be rich in nitrogen. i ... | 2001 | 11265792 |
| controlling self-incompatibility by co2 gas treatment in brassica campestris: structural alteration of papillae cell and differential gene expression by increased co2 gas. | self-imcompatibility is a controlling genetic mechanism to prevent self-pollination for chinese cabbage (brassica campestris), one of the major vegetable crops in korea. to maintain inbred lines of the crop plant, a method in that high co2 gas is treated to the pistils to overcome the self-incompatibility and thereby self-pollens can successfully make germination and fertilization has been widely used in seed companies. despite the common utilization of this method, any molecular and cellular st ... | 2001 | 11355699 |

| purification and characterization of dihydroxyacetone phosphate reductase from immature seeds of brassica campestris l. | dihydroxyacetone phosphate reductase (dhap reductase) was purified to apparent electrophoretic homogeneity with about 24% recovery from immature seeds of brassica campestris using (nh(4))(2)so(4) fractionation, affinity chromatography, gel filtration and adsorption chromatography. the purified enzyme with molecular mass of about 62 kda was a dimer with subunit molecular mass of 32 kda. the enzyme exhibited maximum activity at ph 7.5 and was highly specific for nadh and dhap. typical michaelis-me ... | 2001 | 11448735 |
| trace gases generated in closed plant cultivation systems and their effects on plant growth. | interactions between plants and trace gases, especially ethylene, were investigated from two different viewpoints; ethylene is toxic for plant growth, whereas the ethylene release rate of plants can be utilized as a plant growth indicator. when lettuce plants and shiitake mushroom mycelium were cultivated in closed chambers, ethylene concentration increased with time. ethylene was released both from lettuce plant and from shiitake mushroom mycelium. dioctyl phthalate (dop) and dibutyl phthalate ... | 1995 | 11541892 |
| flowering plant sperm contains a cytosolic soluble protein factor which can trigger calcium oscillations in mouse eggs. | there is evidence showing that the sperm-induced ca(2+) oscillations in mammalian eggs at fertilization are triggered by a sperm-derived protein factor. it was established recently that the activity of the putative sperm protein in causing ca(2+) oscillations in mammalian eggs is not species-specific in vertebrates (1, 16). here we report that cytosolic soluble extracts derived from flowering plant sperms in brassica campestris can also induce fertilization-like ca(2+) oscillations when microinj ... | 2001 | 11549252 |
| the tomato mosaic tobamovirus movement protein interacts with a putative transcriptional coactivator kelp. | viral movement through plasmodesmata in host plants likely depends on the interaction between virus-encoded movement protein (mp) and host proteins. in order to search for mp-interacting protein (mip), we carried out far-western screening of a brassica campestris cdna library using a recombinant mp of tomato mosaic tobamovirus (tomv) as a probe. one of the positive clones, designated mip102, was found to be a putative orthologue for a transcriptional coactivator kelp of arabidopsis thaliana. in ... | 2001 | 11561731 |

| a protein kinase activated by darkness phosphorylates nitrate reductase in komatsuna (brassica campestris) leaves. | although it has been shown that leaf nitrate reductase (nr: ec 1.6.6.1) is phosphorylated by subjecting plants to darkness, there is no evidence for the existence of dark-activated or dark-induced nr kinase. this study was undertaken to investigate the occurrence of a protein kinase phosphorylating nr in response to dark treatments. immediately after transferring komatsuna (brassica campestris l.) plants to darkness, we observed rapid increases in the phosphorylating activity of the synthetic pe ... | 2002 | 12121455 |

| effects of inhibitors of protein serine/threonine phosphatases on pollination in brassica. | we have examined the effect of the protein phosphatase inhibitors okadaic acid and microcystin on pollen-pistil interactions in brassica. inhibitor-treated flowers or floral buds were pollinated with untreated pollen and examined for pollen tube growth by fluorescence microscopy. our results show that type 1 or type 2a serine/threonine phosphatases play a crucial role in the pollination responses of brassica. we observed two distinct effects of protein phosphatase inhibitors on pollination: (a) ... | 1993 | 12232009 |
| immunopurification and immunocharacterization of the glucosinolate biosynthetic enzyme thiohydroximate s-glucosyltransferase. | preparing homogeneous udp-glucose:thiohydroximate s-glucosyltransferase (s-gt), the penultimate biosynthetic enzyme of glucosinolates, by standard chromatographic methods has yielded too little protein for adequate purity evaluation, identity verification, and structural analysis. the low yields were apparently due to low abundance in source tissues, aggravated by enzyme instability. here we describe an immunological method for purification of workable quantities from florets of brassica olerace ... | 1994 | 12232212 |
