A comparative analysis of plastome evolution in autotrophic Piperales

open access: yesAmerican Journal of Botany, Volume 111, Issue 3, March 2024.
Abstract Premise Many plastomes of autotrophic Piperales have been reported to date, describing a variety of differences. Most studies focused only on a few species or a single genus, and extensive, comparative analyses have not been done. Here, we reviewed publicly available plastome reconstructions for autotrophic Piperales, reanalyzed publicly ...
