A tomato xylem sap protein represents a new family of small cysteine-rich proteins with structural similarity to lipid transfer proteins

AbstractThe coding sequence of a major xylem sap protein of tomato was identified with the aid of mass spectrometry. The protein, XSP10, represents a novel family of extracellular plant proteins with structural similarity to plant lipid transfer proteins. The XSP10 gene is constitutively expressed in roots and lower stems. The decline of XSP10 protein levels in tomato infected with a fungal vascular pathogen may reflect breakdown or modification by the pathogen

ABO blood group genotyping of multiple single nucleotide polymorphisms using SnaPshot.

A novel reproducible strategy to type the ABO blood group system by the minisequencing of five nucleotide positions using SNaPshot (Applied Biosystem, USA) is described. This new technique has been successfully applied on 30 blood donors and the results agree with the known serologically based predicted genotypes. (C) 2003 Elsevier B.V. All rights reserved

New Magnetically Recoverable Palladium Metal Catalyst Supported on Poly(1-oxo-trimethylene)-Magnetite

Very recently, magnetic particles have emerged as viable alternatives to conventional materials as heterogeneous catalyst supports which could be recovered in a facile manner from the reaction mixture. In the reaction medium, however, magnetite can influence the catalytic activity and/or it can lose its magnetic properties. Recently, in some papers it has been proposed to encapsulate the magnetite on protective polymers with the aim to preserve the magnetic properties and avoid negative influences on the catalytic activity. In this study, we generated a heterogeneous Pd-catalyst magnetically recoverable by using the perfectly alternated poly(1-oxo-trimethylene) (called polyketone, PK) as supporting material insolvable in the main traditional solvents
