Plant Sterol Diversity in Pollen from Angiosperms.

Numai utilizatorii înregistrați pot traduce articole

Here we have examined the composition of free sterols and steryl esters of pollen from selected angiosperm species, as a first step towards a comprehensive analysis of sterol biogenesis in the male gametophyte. We detected four major sterol structural groups: cycloartenol derivatives bearing a

Increased sterol biosynthesis in tobacco calli resistant to a triazole herbicide which inhibits demethylation of 14α-methyl sterols.

The γ-keto triazole derivative 4,4-dimethyl-1-(2-methoxyphenyl)-1-(1,2,4-triazol-1-yl)-1-penten-3-one is toxic to Nicotiana tabacum L. cv. Xanthi plants or cell cultures. Analysis of the sterol composition of treated wild-type plant material demonstrates that this herbicide is an inhibitor of the

Heligmosomoides polygyrus Venom Allergen-like Protein-4 (HpVAL-4) is a sterol binding protein.

Heligmosomoides polygyrus bakeri is a model parasitic hookworm used to study animal and human helminth diseases. During infection, the parasite releases excretory/secretory products that modulate the immune system of the host. The most abundant protein family in excretory/secretory products

Identification of cDNAs encoding sterol methyl-transferases involved in the second methylation step of plant sterol biosynthesis.

Two methyl transfers are involved in the course of plant sterol biosynthesis and responsible for the formation of 24-alkyl sterols (mainly 24-ethyl sterols) which play major roles in plant growth and development. The first methyl transfer applies to cycloartenol, the second one to 24-methylene

Virus-induced silencing of sterol biosynthetic genes: identification of a Nicotiana tabacum L. obtusifoliol-14alpha-demethylase (CYP51) by genetic manipulation of the sterol biosynthetic pathway in Nicotiana benthamiana L.

Numai utilizatorii înregistrați pot traduce articole

Obtusifoliol-14alpha-demethylase (CYP51) is implicated in plant sterol biosynthesis. An Arabidopsis expressed sequence tag encoding a CYP51 was used as a probe to isolate Nicotiana tabacum L. cDNAs. Two types of cDNA clones were identified. Nt CYP51-1 and Nt CYP51-2 shared 97% identity together and

Cloning and expression of two sterol C-24 methyltransferase genes from upland cotton (Gossypium hirsuturm L.).

Numai utilizatorii înregistrați pot traduce articole

Brassinosteroids (BRs) are an important class of plant steroidal hormones that are essential in a wide variety of physiological processes. Two kinds of intermediates, sitosterol and campesterol, play a crucial role in cell elongation, cellulose biosynthesis, and accumulation. To illuminate the

Plant oxidosqualene metabolism: cycloartenol synthase-dependent sterol biosynthesis in Nicotiana benthamiana.

Numai utilizatorii înregistrați pot traduce articole

The plant sterol pathway exhibits a major biosynthetic difference as compared with that of metazoans. The committed sterol precursor is the pentacyclic cycloartenol (9β,19-cyclolanost-24-en-3β-ol) and not lanosterol (lanosta-8,24-dien-3β-ol), as it was shown in the late sixties. However, plant

Plant sterol biosynthesis: identification of two distinct families of sterol 4alpha-methyl oxidases.

Numai utilizatorii înregistrați pot traduce articole

In plants, the conversion of cycloartenol into functional phytosterols requires the removal of the two methyl groups at C-4 by an enzymic complex including a sterol 4alpha-methyl oxidase (SMO). We report the cloning of candidate genes for SMOs in Arabidopsis thaliana, belonging to two distinct

Plant sterol-C24-methyl transferases: different profiles of tobacco transformed with SMT1 or SMT2.

Numai utilizatorii înregistrați pot traduce articole

Higher plant cells contain a mixture of 24-desmethyl, 24-methyl(ene), and 24-ethyl(idene) sterols in given proportions according to species but also to cell type. As a first step to investigate the function of such sterol compositions in the physiology of a plant, we have illustrated in the present

Sterol Changes during Germination of Nicotiana tabacum Seeds.

Numai utilizatorii înregistrați pot traduce articole

The identity, composition, and concentration of the total, free, esterified, and glycosidic sterol fractions were determined during germination of tobacco seeds. The total, free, and esterified sterols increased, with stigmasterol and campesterol accounting for most of the increase. Steryl

Sterol and sesquiterpenoid biosynthesis during a growth cycle of tobacco cell suspension cultures.

Numai utilizatorii înregistrați pot traduce articole

The accumulation and biosynthesis of sterols and fungal elicitor-inducible sesquiterpenoids by tobacco (Nicotiana tabacum) cell suspension cultures were examined as a function of a 10 day culture cycle. Sterols accumulated concomitantly with fresh weight gain. The rate of sterol biosynthesis,

Sterol composition and growth of transgenic tobacco plants expressing type-1 and type-2 sterol methyltransferases.

Numai utilizatorii înregistrați pot traduce articole

Transgenic tobacco (Nicotiana tabacum L.) plants with altered sterol composition were generated by transformation with plant cDNAs encoding type-1 and type-2 sterol methyltransferases (SMTs; EC 2.1.1.41). For both SMT1 and SMT2 transformants, the transformation was associated with a reduction in the

Plant growth retardants as inhibitors of sterol biosynthesis in tobacco seedlings.

Three plant-growth retardants 2'-isopropy1-4'-(trimethylammonium chloride)-5-methylphenylpiperidine carboxylate (Amo 1618), beta-chloroethyltrimethylammonium chloride, and tributyl-2, 4-dichlorobenzylphosphonium chloride were tested for their effects on sterol production in, and growth of tobacco

Sterol-dependent induction of plant defense responses by a microbe-associated molecular pattern from Trichoderma viride.

Numai utilizatorii înregistrați pot traduce articole

Plant-microbe interactions involve numerous regulatory systems essential for plant defense against pathogens. An ethylene-inducing xylanase (Eix) of Trichoderma viride is a potent elicitor of plant defense responses in specific cultivars of tobacco (Nicotiana tabacum) and tomato (Solanum

Expression of the Hevea brasiliensis (H.B.K.) Mull. Arg. 3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase 1 in Tobacco Results in Sterol Overproduction.
