Ingia / Ingia

The physiology of light-induced phototropic curvature has been studied extensively in coleoptiles of grasses, particularly in Avena and Zea mays L. In Z. mays L., we have found that, in addition to curvature, blue light also induces rapid phosphorylation of a 114-kD protein in the tips of

Purification and Identification of a Plasma Membrane Associated Electron Transport Protein from Maize (Zea mays L.) Roots.

Ingia / Ingia

Plasma membranes isolated from three-day-old maize (Zea mays L.) roots by aqueous two-phase partitioning were used as starting material for the purification of a novel electron transport enzyme. The detergent-solubilized enzyme was purified by dyeligand affinity chromatography on Cibacron blue

Kinetic and chemical analyses of the cytokinin dehydrogenase-catalysed reaction: correlations with the crystal structure.

Ingia / Ingia

CKX (cytokinin dehydrogenase) is a flavoprotein that cleaves cytokinins to adenine and the corresponding side-chain aldehyde using a quinone-type electron acceptor. In the present study, reactions of maize (Zea mays) CKX with five different substrates (N6-isopentenyladenine, trans-zeatin, kinetin,

The oligomeric structures of plant cryptochromes.

Ingia / Ingia

Cryptochromes (CRYs) are a group of evolutionarily conserved flavoproteins found in many organisms. In plants, the well-studied CRY photoreceptor, activated by blue light, plays essential roles in plant growth and development. However, the mechanism of activation remains largely unknown. Here, we

Expression of succinate dehydrogenase and fumarase genes in maize leaves is mediated by cryptochrome.

Ingia / Ingia

Blue light inhibits succinate dehydrogenase and fumarase enzyme activity and gene expression in green leaves of maize (Zea mays L.). Irradiation of maize plants by blue light resulted in the transient decrease of transcripts of genes Sdh1-2 and Sdh2-3 encoding correspondingly the flavoprotein and

Molecular and biochemical characterization of a cytokinin oxidase from maize.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

It is generally accepted that cytokinin oxidases, which oxidatively remove cytokinin side chains to produce adenine and the corresponding isopentenyl aldehyde, play a major role in regulating cytokinin levels in planta. Partially purified fractions of cytokinin oxidase from various species have been

Heterologous expression and biochemical characterization of a polyamine oxidase from Arabidopsis involved in polyamine back conversion.

Ingia / Ingia

Polyamine oxidase (PAO) is a flavin adenine dinucleotide-dependent enzyme involved in polyamine catabolism. Animal PAOs oxidize spermine (Spm), spermidine (Spd), and/or their acetyl derivatives to produce H2O2, an aminoaldehyde, and Spd or putrescine, respectively, thus being involved in a polyamine

Kinetic and structural investigation of the cytokinin oxidase/dehydrogenase active site.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Cytokinins are hormones that regulate plant development and their environmental responses. Their levels are mainly controlled by the cytokinin oxidase/dehydrogenase (CKO), which oxidatively cleaves cytokinins using redox-active electron acceptors. CKO belongs to the group of flavoproteins with an

Involvement of polyamine oxidase in wound healing.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Hydrogen peroxide (H(2)O(2)) is involved in plant defense responses that follow mechanical damage, such as those that occur during herbivore or insect attacks, as well as pathogen attack. H(2)O(2) accumulation is induced during wound healing processes as well as by treatment with the wound signal
