Our analysis of a broad sample of microsporidian genomes demonstrates that the tempo and mode of genome evolution in this group has been far more dynamic than previously appreciated: Following a massive loss of vertically inherited gene families in the LCMA, a process of gene family formation and expansion has substantially enlarged the core microsporidian proteome.
Because only a few wild spinach accessions were tested in previous studies (Hu et al. 2007; Fuentes-Bazan et al. 2012), we undertook a molecular phylogenetic analysis of a broad sample of Spinacia stocks, including S. turkestanica Ilj. and S. tetrandra Stev.

A broad sample of outgroup taxa, representing the ancestral arrangement of the sex chromosomes, was also included in the analysis.
Our analysis was based on a broad sampling of H. e. chestertonii which enabled the confirmation of two principal groups of mitochondrial haplotypes.

This special issue provides a broad sampling of the current state of the art for heparin analysis and characterization.
Such a project would require analysis of a broad, representative sample of tweets on the subject, along with information on who produced or shared such tweets — a process that typically takes weeks or months of work.
