A fungus detected from the importing seeds of Papaver rhoeas under plant quarantine inspection in Korea was identified as Brachycladium penicillatum Corda. It differed in morphological characteristics from a similar species, B. papaveris, which was known to form no macroconidiophores and no microsclerotia. Since the first interception in 2006, this fungus has frequently been found from importin...
BACKGROUND Papaver rhoeas possesses a gametophytic self-incompatibility (SI) system not homologous to any other SI mechanism characterized at the molecular level. Four previously published full length stigmatic S-alleles from the genus Papaver exhibited remarkable sequence divergence, but these studies failed to amplify additional S-alleles despite crossing evidence for more than 60 S-alleles i...
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...
papaver rhoeas l. hydroalcoholic extract exacerbates forced swimming test-induced depression in mice
introduction: depression is one of the most frequent psychiatric disorders in the world with occurs with higher incidence in women. in the present study, the effect of water-alcoholic extract of papaver rhoeas l. on forced swimming test (fst) in swiss-webster mice were examined. methods: we used swiss-webster mice (20-25 g) to execute fst on them. the plant extract (1, 10, 30, and 100 mg/kg) wa...
The electronic form of this issue, available as of September 11, 2007, at www.plantphysiol.org, is considered the journal of record. On the Cover: Many plants use self-incompatibility (SI) to reject genetically identical (‘‘self’’) pollen to prevent inbreeding. In Papaver rhoeas (the field poppy), SI triggers a Ca-dependent signaling network in incompatible pollen, involving several targets, in...
Self-incompatibility (SI) prevents inbreeding through specific recognition and rejection of incompatible pollen. In incompatible Papaver rhoeas pollen, SI triggers a Ca2+ signaling cascade, resulting in the inhibition of tip growth, actin depolymerization, and programmed cell death (PCD). We investigated whether actin dynamics were implicated in regulating PCD. Using the actin-stabilizing and d...
Alnus glutinosa, Fraxinus excelsior and Papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. As part of our continuing screening of plant extracts for activities, the extracts of A. glutinosa, F. excelsior and P. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. Among ...
