Abstract
Quail poisoning is known to produce an acute myoglobinuric syndrome called coturnism. The cause of this syndrome is still unknown, although it has been postulated that Galeopsis ladanum L. seeds, in particular lipidic compounds or stachydrine, are responsible for this toxicity. Thus, we aimed to study the implication of this plant in coturnism in order to explore the physiopathology of the disease, especially with regard to stachydrine and lipidic compounds extracted from seeds. For this purpose, Wistar rats were fed with G. ladanum seed extracts or with quail meat. However, the rhabdomyolysis outbreak could not be reproduced in any case. Therefore, in view of our results and experimental conditions, seeds of G. ladanum and stachydrine do not appear to be the responsible agents of the myopathic outbreak. This conclusion is supported by the following facts: direct administration of extracts of seeds of G. ladanum or stachydrine produces no myotoxicity in rats; G. ladanum seeds are not toxic to quails and meat from quails fed G. ladanum seeds is not toxic to rats.

Abstract
ABA exogenously applied to the leaves of the whole plants of pear (Pyrus bretschneideri Redh. cv. Suly grafted on Pyrus betulaefolia Rehd.) significantly increased the betaine concentrations in the leaves when the plants were well watered. The plants subjected to 'drought plus ABA' treatment had significantly higher betaine concentrations in their leaves than those given drought treatment alone. The 'drought plus ABA' treatment increased the amount of betaine aldehyde dehydrogenase (BADH, EC 1.2.1.8) and its activity in the leaves more than did the drought treatment alone. The experiments with detached leaves showed that ABA treatment significantly increased the concentration of betaine, activity of BADH and apparent amount of BADH in non-dehydrated leaves, and enhanced the accumulation of betaine, activity of BADH and apparent amount of BADH in dehydrated leaves. These effects of ABA were both time- and dose-dependent. Two ABA isomers, (-)-cis, trans-ABA and 2-trans, 4-trans-ABA, had no effect on the betaine accumulation in the leaves, showing that the ABA-induced effects are specific. These data demonstrate that ABA is involved in the drought-induced betaine accumulation in the pear leaves.

Abstract
Betaine aldehyde dehydrogenase (BADH; EC 1.2.1.8) is the enzyme that catalyzes the second step in the synthesis of the osmoprotectant, glycine betaine. NAD-dependent BADH was purified from Avena sativa shoots by DEAE Sephacel, hydroxyapatite, 5'-AMP Sepharose 4B, Mono Q and TSK-GEL column chromatographies to homogeneity by the criterion of native PAGE, and the properties of BADH were compared with those of aminoaldehyde dehydrogenase purified to homogeneity from A. sativa. The molecular mass estimated by both gel filtration using TSK-GEL column and Sephacryl S-200 was 120 and 115, kDa, respectively. The enzyme is a homodimer with a subunit molecular mass of 61 kDa as shown by SDS-PAGE. The pI value of the enzyme was found to be 6.3. The purified enzyme catalyzed not only the oxidation of betaine aldehyde (BAL), but also that of aminoaldehydes, 3-aminopropionaldehyde (APAL), 4-aminobutyraldehyde (ABAL), and 4-guanidinobutyraldehyde (GBAL). The K(m) values for BAL, APAL, ABAL and GBAL were 5x10(-6), 5.4x10(-7), 2.4x10(-5) and 5x10(-5) M, respectively. APAL showed substrate inhibition at a concentration of 0.1 mM. A fragment of BADH cleaved by V8 protease shared homology with other plant BADHs.

Abstract
Betaine aldehyde dehydrogenase (BADH) is an important enzyme for Gly betaine synthesis. We isolated two types of BADH cDNAs (BBD1 and BBD2) from barley. As BBD1 contained the signal sequence (SKL) targeting to microbodies, BBD2 was more similar to previously reported genes coding for BADH in dicotyledons (chloroplast type) than those in monocotyledons (microbody type). The two barley BADH genes showed different expression patterns. The BBD1 transcript was more abundant in roots than leaves and was induced to higher levels by salt, drought and abscisic acid (ABA) treatment. BBD2 transcript was more abundant in leaves and induced by salt, drought, PEG and ABA treatment. To understand the processing of these BADH proteins, we partially purified both enzymes and determined their N-terminal sequences. Based on comparisons of the N-terminal sequences to their deduced amino acid sequence, neither BBD1 nor BBD2 is processed at the N-terminus. These results suggest that BBD2 codes for a new type of BADH, which is not localized in either chloroplasts or mitochondria.

Abstract
Betaine aldehyde dehydrogenase was purified to homogeneity from wild-type amaranth plants subjected to water deficit. The enzyme has a native molecular mass of 125 kDa; it is formed by two subunits, one of the subunits with a molecular mass of 63 kDa and the second one of 70 kDa as determined by SDS-PAGE and double dimension electrophoresis. IEF studies showed two bands with pI values of 4.93 and 4.85, respectively. Possible glycosilation of the 63- and 70-kDa subunits were tested with negative results. Both subunits cross-reacted strongly with polyclonal antibody raised against porcine kidney BADH. Also antiserum rose against HSP70 cross-reacted strongly with the wild amaranth BADH 70-kDa subunit. The enzyme was stable to extreme pH's and temperatures, and high KCl concentrations. Product inhibition of BADH was not observed.

Abstract
An NAD-linked aldehyde dehydrogenase which in addition to aliphatic and aromatic aldehydes, metabolizes aminoaldehydes and betaine aldehyde, has been purified to homogeneity from male Sprague-Dawley rat liver mitochondria. The properties of the rat mitochondrial enzyme are similar to those of a rat liver cytoplasmic betaine aldehyde dehydrognase and the human cytoplasmic E3 isozyme. The primary structure. of four tryptic peptides were also similar; only one difference in primary structure was observed. The close similarity of properties of the cytoplasmic with the mitochondrial form suggest that the cytoplasmic and mitochondrial betaine aldehyde dehydrogenase may be coded for by the same nuclear gene. Investigation of the mitochondrial form by isoelectric focusing resulted in visualization of multiple forms, different from those seen in the cytoplasm suggesting that the enzyme may be processed in the mitochondria.

Abstract
According to our knowledge, this is the first purification method developed, enabling isolation of a homogeneous aminoaldehyde dehydrogenase (AMADH) from etiolated pea seedlings. The procedure involved initial purification with precipitants followed by three low pressure chromatographic steps. Partially purified enzyme was further subjected to fast protein liquid chromatography on a Mono Q column and to affinity-interaction chromatography on 5'-AMP Sepharose. Purity of the final enzyme preparation was checked by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and chromatofocusing. Pea AMADH exists as a tetramer of 230 kDa in the native state, a molecular mass of one subunit was determined as 57 kDa. The enzyme was found to be an acidic protein with pI 5.4. AMADH showed a broad substrate specificity utilising various aminoaldehydes (C3-C6) as substrates. The best substrate of pea AMADH was 3-aminopropionaldehyde, the enzyme also efficiently oxidised 4-aminobutyraldehyde and omega-guanidinoanalogues of the aminoaldehydes. Pea AMADH was inhibited by SH reagents, several elementary aldehydes and metal-binding agents. Although AMADH did not oxidise betaine aldehyde at all, the N-terminal amino acid sequence of the enzyme shows a high degree of homology with those of plant betaine aldehyde dehydrogenases (BADHs) of spinach, sugar beet and amaranth. Several conserved amino acids were found in comparison with BADH from cod liver of known crystal structure.

Abstract
Many plants, as well as other organisms, accumulate betaine (N,N,N-trimethylglycine) as a nontoxic or protective osmolyte under saline or dry conditions. In plants, the last step in betaine synthesis is catalyzed by betaine-aldehyde dehydrogenase (BADH, EC 1.2.1.8), a nuclear-encoded chloroplastic enzyme. A cDNA clone for BADH (1812 base pairs) was selected from a lambda gt10 cDNA library derived from leaves of salt-stressed spinach (Spinacia oleracea L.). The library was screened with oligonucleotide probes corresponding to amino acid sequences of two peptides prepared from purified BADH. The authenticity of the clone was confirmed by nucleotide sequence analysis; this analysis demonstrated the presence of a 1491-base-pair open reading frame that contained sequences encoding 12 peptide fragments of BADH. The clone hybridized to a 1.9-kilobase mRNA from spinach leaves; this mRNA was more abundant in salt-stressed plants, consistent with the known salt induction of BADH activity. The amino acid sequence deduced from the BADH cDNA sequence showed substantial similarities to those for nonspecific aldehyde dehydrogenases (EC 1.2.1.3 and EC 1.2.1.5) from several sources, including absolute conservation of a decapeptide in the probable active site. Comparison of deduced and determined amino acid sequences indicated that the transit peptide may comprise only 7 or 8 residues, which is atypically short for precursors to stromal proteins.

Abstract
Members of the Chenopodiaceae can accumulate high levels (>100 μmol·(g DW)(-1)) of glycine betaine (betaine) in leaves when salinized. Chenopodiaceae synthesize betaine by a two-step oxidation of choline (choline→betaine aldehyde→ betaine), with the second step catalyzed by betaine aldehyde dehydrogenase (BADH, EC 1.2.1.8). High betaine levels have also been reported in leaves of species from several distantly-related families of dicotyledons, raising the question of whether the same betaine-synthesis pathway is used in all cases.Fast atom bombardment mass spectrometry showed that betaine levels of >100 μmol·(g DW)(-1) are present in Lycium ferocissimum Miers (Solanaceae), Helianthus annuus L. (Asteraceae), Convolvulus arvensis L. (Convolvulaceae), and Amaranthus caudatus L. (Amaranthaceae), that salinization promotes betaine accumulation in these plants, and that they can convert supplied choline to betaine aldehyde and betaine. Nicotiana tabacum L. and Lycopersicon lycopersicum (L.) Karst. ex Farw. (Solanaceae), Lactuca sativa L. (Asteraceae) and Ipomoea purpurea L. (Convolvulaceae) also contained betaine, but at a low level (0.1-0.5 μmol·(g DW)(-1). Betaine aldehyde dehydrogenase activity assays, immunotitration and immunoblotting demonstrated that the betaine-accumulating species have a BADH enzyme recognized by antibodies raised against BADH from Spinacia oleracea L. (Chenopodiaceae), and that the Mr of the BADH monomer is in all cases close to 63 000. These data indicate that the choline→betaine aldehyde→betaine pathway may have evolved by vertical descent from an early angiosperm ancestor, and might be widespread (albeit not always strongly expressed) among flowering plants. Consistent with these suggestions, Magnolia x soulangiana was found to have a low level of betaine, and to express a protein of Mr 63 000 which cross-reacted with antibodies to BADH from Spinacia oleracea.

Abstract
Spinach (Spinacia oleracea L.) leaves contain a nuclear-encoded chloroplastic betaine aldehyde dehydrogenase (EC 1.2.1.8) which is induced several-fold by salinization. Betaine aldehyde dehydrogenase was purified 2400-fold to homogeneity with an overall yield of 14%. The procedure included fractional precipitation with ammonium sulfate, followed by ion-exchange, hydrophobic interaction, and hydroxyapatite chromatography in open columns, and ion-exchange and hydrophobic interaction chromatography in a fast-protein liquid chromatography system. The betaine aldehyde dehydrogenase had a pI of 5.65, and a broad pH optimum between 7.5 and 9.5. The Km values for NAD+ and NADP+ were 20 and 320 microM, respectively; the Vmax of the reaction with NADP+ was 75% of that with NAD+. The native enzyme is a dimer with subunits of Mr 63,000. Highly specific antiserum was raised against the native enzyme, and was used in conjunction with cell-free translation of leaf poly(A)+ RNA to show (a) that betaine aldehyde dehydrogenase is synthesized as a precursor of Mr 1200 higher than the mature polypeptide, and (b) that both chronic salt stress and salt shock provoke a several-fold increase in the level of translatable message for the enzyme.
