What's the difference between gamopetalous and plumbagineous?
Gamopetalous
Definition:
(a.) Having the petals united or joined so as to form a tube or cup; monopetalous.
Example Sentences:
Plumbagineous
Definition:
(a.) Pertaining to natural order (Plumbagineae) of gamopetalous herbs, of which Plumbago is the type. The order includes also the marsh rosemary, the thrift, and a few other genera.
Example Sentences:
(1) An excess of oxidative substrate, such as plumbagin, inactivates this enzyme, which appears to be redox-regulated.
(2) polA and recA mutants were not significantly more sensitive than wild type to killing by plumbagin.
(3) Plumbagin and shikonin induced a similar DNA cleavage pattern with topoisomerase II which was different from the cleavage patterns induced with other known topoisomerase II-active drugs.
(4) Plumbagin treatment did not induce lambda phage in a lysogen, nor did it cause an increase in beta-galactosidase production in a dinD::Mu d(lac Ap) promoter fusion strain.
(5) Aqueous leaf extracts from Dionaea muscipula contain quinones such as the naphthoquinone plumbagin that couple to different NADH-dependent diaphorases, producing superoxide and hydrogen peroxide upon autoxidation.
(6) Oxidation of lac permease with the lipophilic quinone plumbagin or alkylation with the sulfhydryl reagent N-ethylmaleimide caused a 12-fold increase in the first dissociation constant.
(7) Plumbagin and shikonin, plant metabolites which have naphthoquinone structures, induced mammalian topoisomerase II-mediated DNA cleavage in vitro.
(8) Hypochlorous acid and plumbagin, both potential sulfhydryl oxidants, induce rapid Ca2+ efflux from SR vesicles; in addition, Cu2+, which catalyzes H2O2 oxidation of cysteine, enhances H2O2-induced release.
(9) Addition of redox cycling agents such as paraquat and plumbagin at various concentrations induced up to 13 proteins in wild-type cells.
(10) Mutations in heat shock genes singly sensitized sodA sodB double mutant cells to plumbagin.
(11) P. aeruginosa showed less cyanide-insensitive respiration than E. coli upon exposure to other redox-active compounds (paraquat, streptonigrin, and plumbagin).
(12) Activity staining demonstrated that (a) anaerobically grown cells contain more extractable dehydratase activity than do aerobically grown cells; (b) exposure of E. coli to 4.2 atm O2 caused virtually complete loss of activity; (c) exposure of cells to paraquat or plumbagin in the presence of dioxygen, but not in its absence, caused a massive loss of activity.
(13) Respiration failed immediately upon the addition of growth-inhibitory levels of plumbagin.
(14) Increases of 3-fold or more were also seen with plumbagin, menadione, and phenazine methosulfate.
(15) The triphasic pattern of inotropism of plumbagin was unaffected by reserpine or propranolol treatments.
(16) Their structures were elucidated, by spectral and chemical studies, as known naphthoquinones, plumbagin, 3,3'-biplumbagin, 8-8'-biplumbagin, and triterpene, lupeol.
(17) Actively growing Escherichia coli cells exposed to plumbagin, a redox cycling quinone that increases the flux of O2- radicals in the cell, were mutagenized or killed by this treatment.
(18) Plumbagin, a compound derived from the roots of Plumbago zeylanica (Chitramool) was studied for its effect on the development of antibiotic resistance using antibiotic sensitive strains of Escherichia coli and Staphylococcus aureus.
(19) Among the selected eight compounds, menadione and plumbagin (aromatic methyl-p-quinone) induced a potent triphasic inotropic response, as reported previously for murrayaquinone-A.
(20) On the other hand, treatment with thiol group oxidants such as 5,5'-dithiobis(2-nitrobenzoic acid), plumbagin and phenazine methosulfate inhibited Gly-Sar transport.
