A wealth of microarray gene expression data and a growing volume of RNA sequencing data are now available in public databases. The authors look at how these data are being used and discuss considerations for how such data should be analysed and deposited and how data reuse could be improved.
Transposable elements are important sources of genetic and epigenetic variation in plant genomes. The author discusses the evidence that this variation has been important for plant evolution and how new genomic resources should allow a systematic assessment of this issue.
A potential role for chromatin in the maintenance of genome integrity has recently emerged. The potential roles for chromatin regulators in coordinating signalling from chromatin during the replication and repair processes, in addition to evidence for a role for chromatin remodellers in accurate segregation, are presented.
