An abundant and heavily truncated non-LTR retrotransposon (LINE) family in Beta vulgaris.

We describe a non-LTR retrotransposon family,BvL, of the long interspersed nuclear elements L1 clade isolated from sugar beet (Beta vulgaris). Characteristic molecular domains of three full-length BvL elements were determined in detail, showing that coding sequences are interrupted and most likely non-functionally. In addition,eight highly conserved endonuclease regions were ...

Diversity in a hidden world: potential and limitation of next-generation sequencing for surveys of molecular diversity of eukaryotic microorganisms

With the delivery of millions of sequence reads in a single experiment, next-generation sequencing (NGS) is currently revolutionizing surveys of microorganism diversity. In particular, when applied to Eukaryotes, we are still lacking a rigorous comparison of morphological and NGS-based diversity estimates. In this report, we studied the diversity and the seasonal community turnover of alveolates ...
