Perception and integration of signals into responses is of crucial importance to cells. Both the actin and microtubule cytoskeleton are known to play a role in mediating diverse stimulus responses. Self-incompatibility (SI) is an important mechanism to prevent self-fertilization. SI in Papaver rhoeas triggers a Ca(2+)-dependent signaling network to trigger programmed cell death (PCD), providing...
Protein phosphorylation regulates numerous cellular processes. Identifying the substrates and protein kinases involved is vital to understand how these important posttranslational modifications modulate biological function in eukaryotic cells. Pyrophosphatases catalyze the hydrolysis of inorganic phosphate (PPi) to inorganic phosphate Pi, driving biosynthetic reactions; they are essential for l...
The active constituents of Korean Papaver rhoeas bee pollen conferring neuraminidase inhibitory activities (H1N1, H3N2, and H5N1) were investigated. Six flavonoids and one alkaloid were isolated and characterized by nuclear magnetic resonance and mass spectrometry data. These included kaempferol-3-sophoroside (1), kaempferol-3-neohesperidoside (2), kaempferol-3-sambubioside (3), kaempferol-3-gl...
Many angiosperms use specific interactions between pollen and pistil proteins as "self" recognition and/or rejection mechanisms to prevent self-fertilization. Self-incompatibility (SI) is encoded by a multiallelic S locus, comprising pollen and pistil S-determinants. In Papaver rhoeas, cognate pistil and pollen S-determinants, PrpS, a pollen-expressed transmembrane protein, and PrsS, a pistil-e...
Catalase enzyme from red poppy (Papaver rhoeas) plant was immobilized covalently with glutaraldehyde onto chitosan particles. The changes in the kinetic properties of the immobilized and free red poppy catalase were determined. The Km values were found to be 26 and 33 mM for free and immobilized red poppy catalase on chitosan. Furthermore, various characteristics of free and immobilized red pop...
Ferulago campestris is an aromatic plant, distributed in Mediterranean Europe, and a source of essential oils (EOs) regarded as promising alternatives to synthetic herbicides pesticides. F. EO, hydrodistilled analyzed, was tested for its antigerminative activity effect on radicle elongation, hydrogen peroxide concentration, lipid peroxidation four infesting weed species (Papaver rhoeas, Taraxac...
