Plant roots are known to harbor large and diverse communities of bacteria. It has been suggested that plant identity can structure these root-associated communities, but few studies have specifically assessed how the composition of root microbiota varies within and between plant species growing under natural conditions. We assessed the community composition of endophytic and epiphytic bacteria ...

We present here the first scientific results obtained with the coronograph described by Beuzit et al. (1996, hereafter paper I), developed to be used together with the come-on-plus/adonis adaptive optics (AO) system. Two IRAS excess Main Sequence (MS) stars, namely HR 4796 and HR 2020 (β Pictoris), have been observed. No circumstellar disk is detected around HR 4796, down to 2′′ from the star. ...

A new clitocyboid genus of Agaricales, Cleistocybe, is described to accommodate the isolated evolutionary position of the new species Cleistocybe vernalis inferred by a previously published multigene phylogenetic study. Cleistocybe is distinguished from other clitocyboid lineages by a combination of morphological characters, including lamellae that become gray in age, an interwoven hymenophoral...
