The liverwort Marchantia polymorpha is a fascinating plant for many reasons, including the fact that it is one of the earliest terrestrial species that split off from the rest of the land plants. Therefore, comparisons between Marchantia and green algae or Marchantia and the rest of the land plants tell…

This issue is rooted in the 37th New Phytologist Symposium on ‘Plant developmental evolution’, 2016, that gathered researchers working on the developing field of plant evo-devo. The issue is a wonderful compendium of work presented during the symposium and the contribution of other researchers working…

A hot topic in plant evolutionary biology is whole genome duplications (WGDs), in which an organism copies its entire genetic dataset. Having double the required DNA is often viewed as detrimental but can be useful in times of rapid environmental change. Recently, the role of WGDs during plant evolution…

The evolution of flowers solved one of the largest obstacles of plant reproduction, finding a compatible mate. Since plants are sedentary, they are unable to search for a compatible mate like other organisms. Instead they use pollinators to do the searching for them. Flowers use scent and color to attract…

The huge set of chemical pathways beyond the conserved primary metabolic network is described as specialized metabolism (formerly known as secondary metabolism). The diversity of specialized metabolites is due to recent evolutionary innovations in enzyme function, as reviewed by Leong and Last. Key processes…

The relationship between plants and arbuscular mycorrhizal fungi has persisted for 400 million years, but we are still learning about the biochemistry of this interaction. MacLean, Bravo and Harrison review how plants attract, recognize, and accommodate their fungal partners, from pre-contact through…

In land plant genomes, transposable elements (TEs) are ubiquitously methylated in CG and non-CG sequence contexts. Apart from methylation of TEs, DNA methylation also occurs on bodies of actively transcribed genes, typically in the CG context, with very low or no non-CG methylation, and is referred to…

DNA sequencing was slow before the development of high throughput sequencing. Portable DNA sequencing, which would make sequencing on-site a reality, was impossible until recently. Parker et al. report on the on-site use of MinION from Oxford Nanopore Technologies for DNA barcoding, which yields data…
