Selected collocations in English: contributions to Business English fluency
The collocations in this text have been selected to make it as useful and easy to use as possible for learners of English. A special effort has been made to identify and incorporate collocations that are used in the business area, thus, contributing to a better business English fluency. The collocations presented here were selected from those identified as significant from multiple sources: The CANCODE Corpus of Spoken English, The Cambridge International Corpus of Written and Spoken English, The Cambridge Learner Corpus, the British National Corpus, the BBI Dictionary of English Word Combinations, the Collins COBUILD English Dictionary, the Oxford Advanced Learnerâs Dictionary, the Oxford Dictionary of English Idioms, the Longman Dictionary of English Collocations, and Tom Cobbâs LexTutor Concordance System

Lifestyle transitions in plant pathogenic Colletotrichum fungi deciphered by genome and transcriptome analyses
Colletotrichum species are fungal pathogens that devastate crop plants worldwide. Host infection involves the differentiation of specialized cell types that are associated with penetration, growth inside living host cells (biotrophy) and tissue destruction (necrotrophy). We report here genome and transcriptome analyses of Colletotrichum higginsianum infecting Arabidopsis thaliana and Colletotrichum graminicola infecting maize. Comparative genomics showed that both fungi have large sets of pathogenicity-related genes, but families of genes encoding secreted effectors, pectin-degrading enzymes, secondary metabolism enzymes, transporters and peptidases are expanded in C. higginsianum. Genome-wide expression profiling revealed that these genes are transcribed in successive waves that are linked to pathogenic transitions: effectors and secondary metabolism enzymes are induced before penetration and during biotrophy, whereas most hydrolases and transporters are upregulated later, at the switch to necrotrophy. Our findings show that preinvasion perception of plant-derived signals substantially reprograms fungal gene expression and indicate previously unknown functions for particular fungal cell types
