TL;DR: The polyploid genome of Brassica napus, which originated from a recent combination of two distinct genomes approximately 7500 years ago and gave rise to the crops of rape oilseed, is sequenced.
Journal ArticleDOI
Endophytic Life Strategies Decoded by Genome and Transcriptome Analyses of the Mutualistic Root Symbiont Piriformospora indica
Alga Zuccaro,Urs Lahrmann,Ulrich Güldener,Gregor Langen,Stefanie Pfiffi,Dagmar Biedenkopf,Philip C. Wong,Birgit Samans,Carolin Grimm,Magdalena Basiewicz,Claude Murat,Francis Martin,Karl-Heinz Kogel +12 more
TL;DR: The findings provide a significant advance in understanding development of biotrophic plant symbionts and suggest a series of incremental shifts along the continuum from saprotrophy towards biotrophy in the evolution of mycorrhizal association from decomposer fungi.
Journal ArticleDOI
MYCN regulates oncogenic MicroRNAs in neuroblastoma.
Johannes H. Schulte,Sebastian Horn,Tobias Otto,Birgit Samans,Lukas C. Heukamp,Ursula-Christa Eilers,Michael Krause,Kathy Astrahantseff,Ludger Klein-Hitpass,Reinhard Buettner,Alexander Schramm,Holger Christiansen,Martin Eilers,Angelika Eggert,Bernd Berwanger +14 more
TL;DR: It is shown here that miR‐221 is also induced by MYCN in neuroblastoma, and miRNA induction is reported to be a new mechanism of gene expression downregulation by Myc.
Journal ArticleDOI
Homoeologous exchange is a major cause of gene presence/absence variation in the amphidiploid Brassica napus
Bhavna Hurgobin,Bhavna Hurgobin,Agnieszka A. Golicz,Philipp E. Bayer,Chon-Kit Kenneth Chan,Soodeh Tirnaz,Aria Dolatabadian,Sarah Schiessl,Birgit Samans,Juan D. Montenegro,Isobel A. P. Parkin,J. Chris Pires,Boulos Chalhoub,Graham J.W. King,Rod J. Snowdon,Jacqueline Batley,David Edwards +16 more
TL;DR: There is an association between HEs and PAV events, particularly in recent Brassica napus synthetic accessions, and these represent a novel source of genetic diversity, which can be captured for the improvement of this important crop species.
Journal ArticleDOI
BMI1 is a target gene of E2F-1 and is strongly expressed in primary neuroblastomas
Katrin Nowak,Kornelius Kerl,Daniel Fehr,Christoph Kramps,Christine Gessner,Katrin Killmer,Birgit Samans,Bernd Berwanger,Holger Christiansen,Werner K. Lutz +9 more
TL;DR: In neuroblastomas deregulated E2F-1 can activate two oncogenes, MYCN and BMI1 that are known to co-operate in tumor formation, and is consistent with a role of Bmi1 in neuroblastoma tumorigenesis.
