Aegilops TEs in Mobile DNA

There's a new open access journal called Mobile DNA, which I'll definitely keep my eye on, as I'm a big fan of mobile DNA. From the website:
Mobile DNA is an online, peer-reviewed open access journal that publishes articles providing novel insights into DNA rearrangements, ranging from transposition and other types of recombination mechanisms to patterns and processes of mobile element and host genome evolution.
The latest ... issue(?) has a really cool article by Belyayev et al. on transposable elements in wheat relative Aegilops speltoides. They looked at a wild population that
is characterized by high heteromorphy and possesses a wide spectrum of chromosomal abnormalities including supernumerary chromosomes, heterozygosity for translocations, and variability in the chromosomal position or number of 45S and 5S ribosomal DNA (rDNA) sites.
Their ultimate goal is to try to match these genomic variations to phenotypic changes. This paper doesn't do that quite yet, but it's a good beginning. I'll definitely be watching future findings from this group.
