TL;DR: More non-seed plant genomes are needed to unravel how plant genomes evolve, and to understand whether the P. patens genome structure is typical for mosses or bryophytes, it is found that 57% of the genome comprises transposable elements (TEs), some of which may be actively transposing during the life cycle.

TL;DR: A de novo assembly for the 375 Mb genome of the perennial model plant, Arabis alpina, revealed long-lasting and recent transposable element activity predominately driven by Gypsy long terminal repeat retrotransposons, which extended the low-recombining pericentromeres and transformed large formerly euchromatic regions into repeat-rich pericentromeric regions.

TL;DR: FindGSE, which fits skew normal distributions to k-mer frequencies to estimate genome size (GS), outperformed existing tools in an extensive simulation study and showed that human GS variations link to geographical patterns and significant differences between populations.

TL;DR: This work generated long-read data of the genomes of three relatives of the model plant Arabidopsis thaliana and assembled all three genomes into only a few hundred contigs, showing that PacBio assemblies have high sequence accuracy but can contain several misassemblies, which join unlinked regions of the genome.

TL;DR: This method provides generally well-supported relationships at interspecific and intergeneric levels that agree with results from more standard phylogenetic analyses of commonly used markers, and it is proposed that this methodology may prove especially useful in groups where there is little genetic differentiation in standard phylogenetics markers.
