Molecular and biochemical analysis of a Madagascar periwinkle root-specific minovincinine-19-hydroxy-O-acetyltransferase. (1/100)
The terminal steps in the biosynthesis of the monoterpenoid indole alkaloids vindoline and minovincinine are catalyzed by separate acetyl coenzyme A-dependent O-acetyltransferases in Madagascar periwinkle (Catharanthus roseus G. Don). Two genes were isolated that had 63% nucleic acid identity and whose deduced amino acid sequences were 78% identical. Active enzymes that were expressed as recombinant His-tagged proteins in Escherichia coli were named minovincinine-19-O-acetyltransferase (MAT) and deacetylvindoline-4-O-acetyltransferase (DAT) because they catalyzed the 19-O-acetylation of indole alkaloids such as minovincinine and horhammericine and the 4-O-acetylation of deacetylvindoline, respectively. Kinetic studies showed that the catalytic efficiency of recombinant MAT (rMAT) was very poor compared with that of recombinant DAT (rDAT), whose turnover rates for Acetyl-coenzyme A and deacetylvindoline were approximately 240- and 10,000-fold greater than those of rMAT. Northern-blot analyses showed that MAT is expressed in cortical cells of the root tip, whereas DAT is only expressed in specialized idioblast and laticifer cells within light exposed tissues like leaves and stems. The coincident expression of trytophan decarboxylase, strictosidine synthase, and MAT within root cortical cells suggests that the entire pathway for the biosynthesis of tabersonine and its substituted analogs occurs within these cells. The ability of MAT to catalyze the 4-O-acetylation of deacetylvindoline with low efficiency suggests that this enzyme, rather than DAT, is involved in vindoline biosynthesis within transformed cell and root cultures, which accumulate low levels of this alkaloid under certain circumstances. (+info)Cloning of a cDNA encoding an E2 ubiquitin-conjugating enzyme from Catharanthus roseus: expression analysis in plant organs and in response to hormones in cell suspensions. (2/100)
A novel cDNA (Crubie2) encoding ubiquitin-conjugating enzyme E2 was isolated from a Catharanthus roseus cDNA library. Sequence comparison with Arabidopsis thaliana E2 sequences revealed that CrUBIE2 is a member of a new plant E2 sub-family. Expression of Crubie2 is repressed in developing organs and down-regulated by cytokinin suggesting that a decrease in the ubiquitin-dependent proteolytic pathway may take part in the regulation of alkaloid biosynthesis in C. roseus cell suspensions. (+info)Inheritance of flower color in periwinkle: orange-red corolla and white eye. (3/100)
The commonly found flower colors in periwinkle (Catharanthus roseus)--pink, white, red-eyed, and pale pink center--are reported to be governed by the epistatic interaction between four genes--A, R, W, and I. The mode of inheritance of an uncommon flower color, orange-red corolla and white eye, was studied by crossing an accession possessing this corolla color with a white flowered variety (Nirmal). The phenotype of the F(1) plants and segregation data of F(2) and backcross generations suggested the involvement of two more interacting and independently inherited genes, one (proposed symbol E) determining the presence or absence of red eye and another (proposed symbol O) determining orange-red corolla. (+info)Expression analysis in plant and cell suspensions of CrCKR1, a cDNA encoding a histidine kinase receptor homologue in Catharanthus roseus (L.) G. Don. (4/100)
A full length cDNA (CrCKR1) encoding a hybrid histidine kinase was isolated from a Catharanthus roseus cDNA library. The kinase belongs to the subfamily of cytokinin receptors represented by CRE1/AHK4/WOL in Arabidopsis thaliana. In cell suspensions, the expression of CrCKR1 is not affected by various stress and hormonal treatments but is stimulated in cells continuously exposed to cytokinin. In plants, CrCKR1 is strongly expressed only in the petals of mature flowers. These data suggest that CrCKR1 could take part in the mechanisms leading to the production of secondary metabolites in C. roseus. (+info)Supercritical fluid extraction and liquid chromatography-electrospray mass analysis of vinblastine from Catharanthus roseus. (5/100)
Supercritical fluid extraction using carbon dioxide modified with methanol, methanol-diethylamine, or methanol-triethylamine was used to extract vinblastine from the aerial portions of Catharanthus roseus. An HPLC-electrospray ionization (ESI)/MS analysis method was also developed to quantify the alkaloids in these extracts. Of the supercritical solvents evaluated, carbon dioxide-methanol-triethylamine (80 : 18 : 2) at 80 degrees C and 34.0 MPa greatly improved the supercritical fluid extraction (SFE) yield of vinblastine by as much as 76.4% over methanol extraction, while the other solvent conditions extracted the compound at yields less than 25% that of a methanol extraction. These results were confirmed by the robust HPLC-ESI/MS analytical method developed in this study. (+info)An early C-22 oxidation branch in the brassinosteroid biosynthetic pathway. (6/100)
The natural occurrence of 22-hydroxylated steroids in cultured Catharanthus roseus cells and in Arabidopsis seedlings was investigated. Using full-scan gas chromatography-mass spectrometry analysis, (22S)-22-hydroxycampesterol (22-OHCR), (22S,24R)-22-hydroxyergost-4-en-3-one (22-OH-4-en-3-one), (22S,24R)-22-hydroxy-5alpha-ergostan-3-one (22-OH-3-one), 6-deoxocathasterone (6-deoxoCT), 3-epi-6-deoxoCT, 28-nor-22-OHCR, 28-nor-22-OH-4-en-3-one, 28-nor-22-OH-3-one, 28-nor-6-deoxoCT, and 3-epi-28-nor-6-deoxoCT were identified. Metabolic experiments with deuterium-labeled 22-OHCR were performed in cultured C. roseus cells and Arabidopsis seedlings (wild type and det2), and the metabolites were analyzed by gas chromatography-mass spectrometry. In both C. roseus cells and wild-type Arabidopsis seedlings, [(2)H(6)]22-OH-4-en-3-one, [(2)H(6)]22-OH-3-one, [(2)H(6)]6-deoxoCT, and [(2)H(6)]3-epi-6-deoxoCT were identified as metabolites of [(2)H(6)]22-OHCR, whereas the major metabolite in det2 seedlings was [(2)H(6)]22-OH-4-en-3-one. Analysis of endogenous levels of these brassinosteroids revealed that det2 accumulates 22-OH-4-en-3-one. The levels of downstream compounds were remarkably reduced compared with the wild type. Exogenously applied 22-OH-3-one and 6-deoxoCT were found to rescue det2 mutant phenotypes, whereas 22-OHCR and 22-OH-4-en-3-one did not. These results substantiate the existence of a new subpathway (22-OHCR --> 22-OH-4-en-3-one --> 22-OH-3-one --> 6-deoxoCT) and reveal that the det2 mutant is defective in the conversion of 22-OH-4-en-3-one to 22-OH-3-one, which leads to brassinolide biosynthesis. (+info)Inhibition of the plant cytokinin transduction pathway by bacterial histidine kinase inhibitors in Catharanthus roseus cell cultures. (7/100)
We describe the isolation of two Catharanthus roseus cDNAs encoding proteins putatively involved in the final steps of a 'histidine-to-aspartate' phosphorelay in cytokinin (CK) signaling. The expression of one of these genes, CrRR1, was specifically up-regulated by CKs in C. roseus cell suspensions. We used this system as a biological model to test the activity of bacterial histidine kinase inhibitors. Our data demonstrate that these inhibitors are active on the CK transduction pathway and represent powerful chemical tools to study hormone signal transduction in plants. Moreover, these data suggest a strong conservation of functional features between prokaryotic and plant signaling pathways utilizing histidine kinases. (+info)Molecular characterization of recombinant T1, a non-allergenic periwinkle (Catharanthus roseus) protein, with sequence similarity to the Bet v 1 plant allergen family. (8/100)
More than 25% of the population suffer from Type I allergy, an IgE-mediated hypersensitivity disease. Allergens with homology to the major birch ( Betula verrucosa ) pollen allergen, Bet v 1, belong to the most potent elicitors of IgE-mediated allergies. T1, a cytokinin-inducible cytoplasmic periwinkle ( Catharanthus roseus ) protein, with significant sequence similarity to members of the Bet v 1 plant allergen family, was expressed in Escherichia coli. Recombinant T1 (rT1) did not react with IgE antibodies from allergic patients, and failed to induce basophil histamine release and immediate-type skin reactions in Bet v 1-allergic patients. Antibodies raised against purified rT1 could be used for in situ localization of natural T1 by immunogold electron microscopy, but did not cross-react with most of the Bet v 1-related allergens. CD analysis showed significant differences regarding secondary structure and thermal denaturation behaviour between rT1 and recombinant Bet v 1, suggesting that these structural differences are responsible for the different allergenicity of the proteins. T1 represents a non-allergenic member of the Bet v 1 family that may be used to study structural requirements of allergenicity and to engineer hypo-allergenic plants by replacing Bet v 1-related allergens for primary prevention of allergy. (+info)'Catharanthus' is a genus of plants in the Apocynaceae family, commonly known as the dogbane family. The most well-known species is Catharanthus roseus, also known as Madagascar periwinkle or rosy periwinkle. This plant contains alkaloids that have been used in the production of drugs for cancer treatment. Vincristine and vinblastine are two such alkaloids derived from C. roseus, which have shown significant anti-cancer properties and are used to treat various types of cancers, including leukemia and lymphoma.
It is important to note that the use of Catharanthus or its derivatives should be under medical supervision due to their potent biological activities and potential side effects.
Secologanin tryptamine alkaloids are a type of alkaloid compound that is derived from the combination of secologanin (a metabolite found in certain plants) and tryptamine (an organic compound that is a building block for several neurotransmitters). These alkaloids have been identified in various plant species, including those in the genera *Psychotria* and *Uncaria*, and are known to exhibit a range of pharmacological activities. Some examples of secologanin tryptamine alkaloids include ajmalicine, reserpine, and yohimbine, which have been used in traditional medicine for their sedative, antihypertensive, and aphrodisiac properties, respectively. However, it is important to note that these compounds can also have toxic effects and should only be used under the guidance of a medical professional.
Vinca alkaloids are a group of naturally occurring chemicals derived from the Madagascar periwinkle plant, Catharanthus roseus. They are known for their antineoplastic (cancer-fighting) properties and are used in chemotherapy to treat various types of cancer. Some examples of vinca alkaloids include vinblastine, vincristine, and vinorelbine. These agents work by disrupting the normal function of microtubules, which are important components of the cell's structure and play a critical role in cell division. By binding to tubulin, a protein that makes up microtubules, vinca alkaloids prevent the formation of mitotic spindles, which are necessary for cell division. This leads to cell cycle arrest and apoptosis (programmed cell death) in cancer cells. However, vinca alkaloids can also affect normal cells, leading to side effects such as neurotoxicity, myelosuppression, and gastrointestinal disturbances.
Carbon-nitrogen (C-N) lyases are a class of enzymes that catalyze the breakdown of a carbon-nitrogen bond, releasing an ammonia molecule and leaving a double bond. These enzymes play important roles in various biological processes, such as the biosynthesis and degradation of amino acids, nucleotides, and other biomolecules.
C-N lyases are classified based on the type of bond they cleave and the cofactors or prosthetic groups they use to catalyze the reaction. Some examples of C-N lyases include:
1. Alanine racemase: This enzyme catalyzes the conversion of L-alanine to D-alanine, which is an important component of bacterial cell walls.
2. Aspartate transcarbamylase: This enzyme catalyzes the transfer of a carbamoyl group from carbamoyl phosphate to aspartate, forming N-carbamoyl aspartate and inorganic phosphate. It is an important enzyme in the biosynthesis of pyrimidines.
3. Diaminopimelate decarboxylase: This enzyme catalyzes the decarboxylation of meso-diaminopimelate to form L-lysine, which is an essential amino acid for humans.
4. Glutamate decarboxylase: This enzyme catalyzes the decarboxylation of glutamate to form γ-aminobutyric acid (GABA), a neurotransmitter in the brain.
5. Histidine decarboxylase: This enzyme catalyzes the decarboxylation of histidine to form histamine, which is involved in various physiological processes such as immune response and allergic reactions.
C-N lyases are important targets for drug development, particularly in the treatment of bacterial infections and neurological disorders.
Indole alkaloids are a type of naturally occurring organic compound that contain an indole structural unit, which is a heterocyclic aromatic ring system consisting of a benzene ring fused to a pyrrole ring. These compounds are produced by various plants and animals as secondary metabolites, and they have diverse biological activities. Some indole alkaloids have important pharmacological properties and are used in medicine as drugs or lead compounds for drug discovery. Examples of medically relevant indole alkaloids include reserpine, which is used to treat hypertension, and vinblastine and vincristine, which are used to treat various types of cancer.
Iridoid glucosides are a type of plant-based compounds that are characterized by their iridoid structure, which is a cyclic organic compound containing a cyclopentane ring fused to a six-membered unsaturated carbocycle. These compounds are often found in plants as glycosides, meaning they are combined with a sugar molecule such as glucose.
Iridoid glucosides have been identified in a variety of plant families, including the Lamiaceae (mint family), Scrophulariaceae (figwort family), and Rubiaceae (coffee family). Some examples of iridoid glucosides include geniposide, which is found in the fruit of the gardenia plant, and aucubin, which is found in the leaves of the eucommia tree.
Iridoid glucosides have been studied for their potential medicinal properties, including anti-inflammatory, antioxidant, and antimicrobial effects. However, more research is needed to fully understand their mechanisms of action and potential therapeutic uses.
"Vinca" is not a medical term itself, but it refers to a group of plants that belong to the genus Vinca or the family Apocynaceae. Some species of Vinca are used in medicine and are known as "vinca alkaloids." These alkaloids include vincristine and vinblastine, which have been isolated from the Madagascar periwinkle (Vinca rosea) plant.
Vincristine and vinblastine are antimicrotubule agents that disrupt microtubule function during mitosis, leading to cell cycle arrest and apoptosis (programmed cell death). They have been used in the treatment of various types of cancer, including leukemias, lymphomas, and testicular cancer.
Therefore, when referring to "Vinca" in a medical context, it typically means the use of vinca alkaloids as anticancer agents.
Iridoids are a type of naturally occurring compounds that are widely distributed in the plant kingdom. They are characterized by the presence of a cyclopentanoid structure fused to a monoterpene unit. Iridoids have a wide range of biological activities, including anti-inflammatory, analgesic, and antioxidant effects. Some iridoids also have potential therapeutic benefits in the treatment of various diseases, such as cancer and neurodegenerative disorders.
In a medical context, iridoids may be mentioned in relation to their presence in certain medicinal plants or herbs used in traditional medicine, or in research investigating their potential pharmacological properties. However, it is important to note that the use of iridoid-containing plants or supplements should only be done under the guidance of a qualified healthcare professional, as with any medical treatment.
I believe there may be a slight misunderstanding in your question. "Plant leaves" are not a medical term, but rather a general biological term referring to a specific organ found in plants.
Leaves are organs that are typically flat and broad, and they are the primary site of photosynthesis in most plants. They are usually green due to the presence of chlorophyll, which is essential for capturing sunlight and converting it into chemical energy through photosynthesis.
While leaves do not have a direct medical definition, understanding their structure and function can be important in various medical fields, such as pharmacognosy (the study of medicinal plants) or environmental health. For example, certain plant leaves may contain bioactive compounds that have therapeutic potential, while others may produce allergens or toxins that can impact human health.
Alkaloids are a type of naturally occurring organic compounds that contain mostly basic nitrogen atoms. They are often found in plants, and are known for their complex ring structures and diverse pharmacological activities. Many alkaloids have been used in medicine for their analgesic, anti-inflammatory, and therapeutic properties. Examples of alkaloids include morphine, quinine, nicotine, and caffeine.
Mesophyll cells are photosynthetic cells located in the interior tissue of a leaf, specifically within the chloroplast-containing portion called the mesophyll. These cells are responsible for capturing sunlight and converting it into chemical energy through the process of photosynthesis. They can be further divided into two types: palisade mesophyll cells and spongy mesophyll cells.
Palisade mesophyll cells are columnar-shaped cells that contain many chloroplasts and are located closer to the upper epidermis of the leaf. They are arranged in one or more layers and are primarily responsible for capturing light during photosynthesis.
Spongy mesophyll cells, on the other hand, are loosely arranged and have a sponge-like structure. They contain fewer chloroplasts than palisade mesophyll cells and are located closer to the lower epidermis of the leaf. These cells facilitate gas exchange between the plant and the environment by allowing for the diffusion of carbon dioxide into the leaf and oxygen out of the leaf.
Overall, mesophyll cells play a critical role in photosynthesis and help to maintain the health and growth of the plant.
Aerial parts of plants refer to the above-ground portions of a plant, including leaves, stems, flowers, and fruits. These parts are often used in medicine, either in their entirety or as isolated extracts, to take advantage of their medicinal properties. The specific components of aerial parts that are used in medicine can vary depending on the plant species and the desired therapeutic effects. For example, the leaves of some plants may contain active compounds that have anti-inflammatory or analgesic properties, while the flowers of others may be rich in antioxidants or compounds with sedative effects. In general, aerial parts of plants are used in herbal medicine to treat a wide range of conditions, including respiratory, digestive, and nervous system disorders, as well as skin conditions and infections.
Vinblastine is an alkaloid derived from the Madagascar periwinkle plant (Catharanthus roseus) and is primarily used in cancer chemotherapy. It is classified as a vinca alkaloid, along with vincristine, vinorelbine, and others.
Medically, vinblastine is an antimicrotubule agent that binds to tubulin, a protein involved in the formation of microtubules during cell division. By binding to tubulin, vinblastine prevents the assembly of microtubules, which are essential for mitosis (cell division). This leads to the inhibition of cell division and ultimately results in the death of rapidly dividing cells, such as cancer cells.
Vinblastine is used to treat various types of cancers, including Hodgkin's lymphoma, non-Hodgkin's lymphoma, testicular cancer, breast cancer, and others. It is often administered intravenously in a healthcare setting and may be given as part of a combination chemotherapy regimen with other anticancer drugs.
As with any medication, vinblastine can have side effects, including bone marrow suppression (leading to an increased risk of infection, anemia, and bleeding), neurotoxicity (resulting in peripheral neuropathy, constipation, and jaw pain), nausea, vomiting, hair loss, and mouth sores. Regular monitoring by a healthcare professional is necessary during vinblastine treatment to manage side effects and ensure the safe and effective use of this medication.
Aromatic-L-amino-acid decarboxylases (ALADs) are a group of enzymes that play a crucial role in the synthesis of neurotransmitters and biogenic amines in the body. These enzymes catalyze the decarboxylation of aromatic L-amino acids, such as L-dopa, L-tryptophan, and L-phenylalanine, to produce corresponding neurotransmitters or biogenic amines, including dopamine, serotonin, and histamine, respectively.
There are two main types of ALADs in humans: dopa decarboxylase (DDC) and tryptophan hydroxylase (TPH). DDC is responsible for the conversion of L-dopa to dopamine, which is a crucial neurotransmitter involved in movement regulation. TPH, on the other hand, catalyzes the rate-limiting step in serotonin synthesis by converting L-tryptophan to 5-hydroxytryptophan (5-HTP), which is then converted to serotonin by another enzyme called aromatic amino acid decarboxylase.
Deficiencies or mutations in ALADs can lead to various neurological and psychiatric disorders, such as Parkinson's disease, dopa-responsive dystonia, and depression. Therefore, understanding the function and regulation of ALADs is essential for developing effective therapies for these conditions.
Phytoplasmas are tiny, wall-less, bacteria-like organisms that lack a cell wall and have a unique, small circular DNA genome. They are classified in the class Mollicutes and are obligate parasites, meaning they can only survive inside living cells. They infect a wide range of plant species, as well as some insects, and can cause various diseases that affect the growth, development, and yield of crops and ornamental plants.
Phytoplasmas are typically transmitted from plant to plant by sap-sucking insects such as leafhoppers, planthoppers, and psyllids. Once inside a plant host, they manipulate the host's metabolism and cause various symptoms, including yellowing of leaves, stunting, witches' broom (excessive branching), virescence (greening of flowers), and phyllody (transformation of floral parts into leaf-like structures).
Phytoplasmas are difficult to culture in the laboratory, which has made their study challenging. However, advances in molecular biology techniques such as PCR and DNA sequencing have facilitated their identification and characterization. Controlling phytoplasma diseases is also a challenge due to their complex transmission cycles and the lack of effective chemical treatments. Management strategies typically involve integrated pest management (IPM) approaches that combine cultural, biological, and chemical methods to reduce disease incidence and spread.
Medicinal plants are defined as those plants that contain naturally occurring chemical compounds which can be used for therapeutic purposes, either directly or indirectly. These plants have been used for centuries in various traditional systems of medicine, such as Ayurveda, Chinese medicine, and Native American medicine, to prevent or treat various health conditions.
Medicinal plants contain a wide variety of bioactive compounds, including alkaloids, flavonoids, tannins, terpenes, and saponins, among others. These compounds have been found to possess various pharmacological properties, such as anti-inflammatory, analgesic, antimicrobial, antioxidant, and anticancer activities.
Medicinal plants can be used in various forms, including whole plant material, extracts, essential oils, and isolated compounds. They can be administered through different routes, such as oral, topical, or respiratory, depending on the desired therapeutic effect.
It is important to note that while medicinal plants have been used safely and effectively for centuries, they should be used with caution and under the guidance of a healthcare professional. Some medicinal plants can interact with prescription medications or have adverse effects if used inappropriately.
Oxylipins are a class of bioactive lipid molecules derived from the oxygenation of polyunsaturated fatty acids (PUFAs). They play crucial roles in various physiological and pathophysiological processes, including inflammation, immunity, and cellular signaling. Oxylipins can be further categorized based on their precursor PUFAs, such as arachidonic acid (AA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and linoleic acid (LA). These oxylipins are involved in the regulation of vascular tone, platelet aggregation, neurotransmission, and pain perception. They exert their effects through various receptors and downstream signaling pathways, making them important targets for therapeutic interventions in several diseases, such as cardiovascular disorders, cancer, and neurological conditions.
"Plant proteins" refer to the proteins that are derived from plant sources. These can include proteins from legumes such as beans, lentils, and peas, as well as proteins from grains like wheat, rice, and corn. Other sources of plant proteins include nuts, seeds, and vegetables.
Plant proteins are made up of individual amino acids, which are the building blocks of protein. While animal-based proteins typically contain all of the essential amino acids that the body needs to function properly, many plant-based proteins may be lacking in one or more of these essential amino acids. However, by consuming a variety of plant-based foods throughout the day, it is possible to get all of the essential amino acids that the body needs from plant sources alone.
Plant proteins are often lower in calories and saturated fat than animal proteins, making them a popular choice for those following a vegetarian or vegan diet, as well as those looking to maintain a healthy weight or reduce their risk of chronic diseases such as heart disease and cancer. Additionally, plant proteins have been shown to have a number of health benefits, including improving gut health, reducing inflammation, and supporting muscle growth and repair.
Cyclopentanes are a class of hydrocarbons that contain a cycloalkane ring of five carbon atoms. The chemical formula for cyclopentane is C5H10. It is a volatile, flammable liquid that is used as a solvent and in the production of polymers. Cyclopentanes are also found naturally in petroleum and coal tar.
Cyclopentanes have a unique structure in which the carbon atoms are arranged in a pentagonal shape, with each carbon atom bonded to two other carbon atoms and one or two hydrogen atoms. This structure gives cyclopentane its characteristic "bowl-shaped" geometry, which allows it to undergo various chemical reactions, such as ring-opening reactions, that can lead to the formation of other chemicals.
Cyclopentanes have a variety of industrial and commercial applications. For example, they are used in the production of plastics, resins, and synthetic rubbers. They also have potential uses in the development of new drugs and medical technologies, as their unique structure and reactivity make them useful building blocks for the synthesis of complex molecules.
I apologize for any confusion, but "plants" is not a term that has a medical definition. The term "plants" refers to a large and diverse group of organisms that obtain their energy through photosynthesis, which is the process of converting sunlight into chemical energy. Plants are typically characterized by having cells with cell walls containing cellulose, chloroplasts containing the pigment chlorophyll, and the ability to synthesize their own food through photosynthesis.
In a medical or biological context, you might be thinking of "plant-based" or "phytomedicine," which refer to the use of plants or plant extracts as a form of medicine or treatment. Phytomedicines have been used for thousands of years in many traditional systems of medicine, and some plant-derived compounds have been found to have therapeutic benefits in modern medicine as well. However, "plants" itself does not have a medical definition.
