Insecticidal Activities of L., Spenn. and L. against (Cockerell) under Laboratory and Greenhouse Conditions.

The wild cochineal (Hemiptera: Dactylopiidae) is one of the major insect pests of the prickly pear (L.) in Morocco, a well-known fruit and vegetable crop of arid and semi-arid regions around the world. The present study investigated the insecticidal potential of six extracts (three aqueous and three hydroalcoholic (MeOH/HO, 20/80 (/)) from (leaves), (leaves) and (seeds) to control nymphs and adult females of under laboratory and greenhouse conditions.

Eryngium caeruleum: an update on ethnobotany, phytochemistry and biomedical applications.

Background: A biennial or perennial plant of the Apiaceae family, Eryngium caeruleum M. Bieb. is traditionally used in medicine as an antitoxic, diuretic, digestive, anti-inflammatory and analgesic drug.

Natural Sources and Pharmacological Properties of Pinosylvin.

Pinosylvin (3,5-dihydroxy--stilbene), a natural pre-infectious stilbenoid toxin, is a terpenoid polyphenol compound principally found in the Vitaceae family in the heartwood of spp. (e.g.

[Hemogram profile and interest of pre-donation hemoglobin measurement in blood donors in the northwest region of Morocco].

Background: Blood donation in Morocco and more particularly in the northwest region is carried out without prior determination of the pre-donation hemoglobin. In addition, we note the lack of scientific research that reports data on the red blood cells, leukocytes and platelet lines in donated blood at the regional or even national level.

Aims: To study hemogram profile in blood donors taken from the Northwest region of Morocco in order to provide decision makers of the National Center of Blood Transfusion and Hematology with valid scientific arguments to complete the criteria to donate whole blood, by the hemogram.

Cryptochrome photoreceptors cry1 and cry2 antagonistically regulate primary root elongation in Arabidopsis thaliana.

Cryptochromes are blue-light receptors controlling multiple aspects of plant growth and development. They are flavoproteins with significant homology to photolyases, but instead of repairing DNA they function by transducing blue light energy into a signal that can be recognized by the cellular signaling machinery. Here we report the effect of cry1 and cry2 blue light receptors on primary root growth in Arabidopsis thaliana seedlings, through analysis of both cryptochrome-mutant and cryptochrome-overexpressing lines.

Phosphoenolpyruvate carboxylase kinase is controlled by a similar signaling cascade in CAM and C(4) plants.

In Crassulacean acid metabolism (CAM) plants, phosphoenolpyruvate carboxylase (PEPC) is subject to day-night regulatory phosphorylation of a conserved serine residue in the plant enzyme's N-terminal domain. The dark increase in PEPC-kinase (PEPC-k) activity is under control of a circadian oscillator, via the enhanced expression of the corresponding gene (1). The signaling cascade leading to PEPC-k up-regulation was investigated in leaves and mesophyll cell protoplasts of the facultative, salt-inducible CAM species, Mesembryanthemum crystallinum.

Regulatory Phosphorylation of C4 Phosphoenolpyruvate Carboxylase (A Cardinal Event Influencing the Photosynthesis Rate in Sorghum and Maize).

C4 leaf phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.

Regulatory phosphorylation of Sorghum leaf phosphoenolpyruvate carboxylase. Identification of the protein-serine kinase and some elements of the signal-transduction cascade.

The phosphoenolpyruvate (PPrv) carboxylase isozyme involved in C4 photosynthesis undergoes a day/night reversible phosphorylation process in leaves of the C4 plant, Sorghum. Ser8 of the target enzyme oscillates between a high (light) and a low (dark) phosphorylation status. Both in vivo and in vitro, phosphorylation of dark-form carboxylase was accompanied by an increase in the apparent Ki of the feedback inhibitor L-malate and an increase in Vmax.
