Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]
, 2016 Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...
