Toward a phylogenomic classification of magnoliids. [PDF]
Abstract Premise Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Phylogenetic Relationships of the Perianthless Piperales: Reconstructing the Evolution of Floral Development [PDF]
The perianthless members of the Piperales are unique among the basal lineages of angiosperms because they are mainly herbaceous plants with over 2000 species possessing highly reduced flowers. There have been several attemptstoaddresstheevolutionoftheflowermorphologyinthegroup,butnopreviousstudyhasincludedaDNAbased estimate of phylogeny.

The First Plastid Genome of the Holoparasitic Genus Prosopanche (Hydnoraceae)
Plastomes of parasitic and mycoheterotrophic plants show different degrees of reduction depending on the plants’ level of heterotrophy and host dependence in comparison to photoautotrophic sister species, and the amount of time since heterotrophic ...

Comprehensive Genomic Dataset of Chinese Lizardtail Herb and Comparative Genomic Analysis Provide Insights Into Its Paleo-Polyploidization Event. [PDF]
In this study, we provided a comprehensive genomic dataset for S. chinensis. Additionally, we observed that the S. chinensis genome underwent a paleo‐tetraploidization event, followed by several chromosome fusion events, resulting in an aneuploid paleo‐tetraploid state in its current genomic structure.

Tiny pollen grains: first evidence of Saururaceae from the Late Cretaceous of western North America [PDF]
Background The Saururaceae, a very small family of Piperales comprising only six species in four genera, have a relatively scanty fossil record outside of Europe. The phylogenetic relationships of the four genera to each other are resolved, with the type

Evolution of Class II TCP genes in perianth bearing Piperales and their contribution to the bilateral calyx in Aristolochia [PDF]
Summary Controlled spatiotemporal cell division and expansion are responsible for floral bilateral symmetry. Genetic studies have pointed to class II TCP genes as major regulators of cell division and floral patterning in model core eudicots. Here we study their evolution in perianth‐bearing Piperales and their expression in Aristolochia, a rare ...
