A set of seven structurally related Sm proteins forms the core of the snRNP particles containing the spliceosomal U1, U2, U4 and U5 snRNAs. A search of the genomic sequence of Saccharomyces cerevisiae has identified a number of open reading frames that potentially encode structurally similar proteins termed Lsm (Like Sm) proteins. With the aim of analysing(More)
Calcineurin phosphatase and cyclophilin A are cellular components involved in fungal morphogenesis and virulence. Their roles were investigated in the phytopathogenic fungus Botrytis cinerea using gene inactivation, drug inhibition and cDNA macroarrays approaches. First, the BCP1 gene coding for cyclophilin A was identified and inactivated by homologous(More)
A large set of genes was identified in the phytopathogenic fungus Botrytis cinerea by using an expressed sequence tag approach. The fungus was grown in axenic culture and a cDNA library was produced. From this library, 6559 ESTs were obtained. The combined sequences represent 3026 unisequences that corresponds to approximately one-quarter of the estimated(More)
Tetraspanins are animal proteins involved in membrane complexes that are involved in cell adhesion, differentiation, and motility. The PLS1 gene from rice blast fungus Magnaporthe grisea encodes a protein (Pls1p) structurally related to tetraspanins that is required for pathogenicity. In Botrytis cinerea public sequences, we identified an EST homologous to(More)
Onset of zygotic transcription is progressive from the one-cell stage onward in the rabbit embryo. Maternal transcripts remain fairly stable until the 8-16 cell stage when major transcriptional activation of the zygotic genome takes place. To understand the mechanisms of the maternal-to-zygotic transition in the genetic information governing development, we(More)
Animal tetraspanins are membrane proteins controlling cell adhesion, morphology and motility. In fungi, the tetraspanin MgPls1 controls an appressorial function required for the penetration of Magnaporthe grisea into host plants. An orthologue of MgPLS1, BcPLS1, was identified in the necrotrophic fungal plant pathogen Botrytis cinerea. We constructed a(More)
