One-Pot Synthesis of N-H-Free Pyrroles from Aldehydes and Alkynes.

The first base-mediated intermolecular cyclization of arylaldehydes and terminal arylacetylenes for the synthesis of a wide range of pyrroles in a single step has been described. The developed methodology used commercially available starting materials and tolerated a broad range of functional groups affording 2,3,5-triaryl-substituted-1-pyrroles with good yields (up to 92% yield) under mild conditions. The possible mechanism was also discussed.

Identification of Development and Pathogenicity Related Gene in Botrytis cinerea via Digital Gene Expression Profile.

Background: Botrytis cinerea, a haploid Euascomycete fungus that infects numerous crops, has been used as a model system for studying molecular phytopathology. Botrytis cinerea adopts various modes of infection, which are mediated by a number of pathogenicity and virulence-related genes. Many of these genes have not been reported previously.

[Molecular cloning and characterization of calcineurin A in Setosphaeria turcica].

A Setosphaeria turcica gene encoding the catalytic subunit of calcineurin was cloned using degenerated primers corresponding to conserved domains of Ser/Thr protein phosphatases and its complete cDNA (GenBank accession No. EF 407562) was obtained with RACE method. It's validated single copied model by southern hybridization.
