Deep Super-SAGE transcriptomic analysis of cold acclimation in lentil (Lens culinaris Medik.).

Background: Frost is one of the main abiotic stresses limiting plant distribution and crop production. To cope with the stress, plants evolved adaptations known as cold acclimation or chilling tolerance to maximize frost tolerance. Cold acclimation is a progressive acquisition of freezing tolerance by plants subjected to low non-freezing temperatures which subsequently allows them to survive exposure to frost.

Simultaneous determination of nine anticoagulant rodenticides in soil and water by LC-ESI-MS.

A new and sensitive analytical method is presented to determine nine anticoagulant rodenticide (chlorophacinone, bromadiolone, pindone, diphacinone, warfarin, coumatetralyl, brodifacoum, floucomafen, and difenacoum) residues in water and soil samples by LC-ESI-MS. Rodenticides were extracted from soil using a methanol and ammonium formate 30 mM mixture, while ethyl acetate was employed in the water samples. A Gemini 5 μm C18 column was employed, and a mobile phase comprising a mixture of ammonium formate 30 mM and di-n-butylamine 30 mM in water (pH 3.

Analysis of anticoagulant rodenticide residues in Microtus arvalis tissues by liquid chromatography with diode array, fluorescence and mass spectrometry detection.

We describe here a fast and selective analytical method to determine the levels of four anticoagulant rodenticides (chlorophacinone, bromadiolone, brodifacoum and difenacoum) in animal tissues by liquid chromatography (LC) using different detection methods: fluorescence (FLD), diode array (DAD) and electrospray ionization-mass spectrometry (ESI-MS). Rodenticides were extracted from freeze-dried and homogenized tissue samples (liver, intestine and muscle) that had been obtained from the common vole (Microtus arvalis). These samples were diluted in 5 mL of methanol, the solution was shaken and centrifuged, and the supernatant was removed and evaporated to dryness.

Strains of Pseudomonas syringae pv. syringae from pea are phylogenetically and pathogenically diverse.

Pseudomonas syringae pv. syringae causes extensive yield losses in the pea crop worldwide, although there is little information on its host specialization and its interactions with pea. A collection of 88 putative P.

Pea detection in food and feed samples by a real-time PCR method based on a specific legumin gene that allows diversity analysis.

Real-time polymerase chain reaction is currently being used for the identification and quantification of plant and animal species as well as microorganisms in food or feed samples based on the amplification of specific sequences of low copy genes. We report here the development of a new real-time PCR method for the detection and quantification of the pea (Pisum sativum) based on the amplification of a specific region of the legS gene. The specificity was evaluated in a wide range of plant species (51 varieties of Pisum sp.
