Convergence and parallelism in the evolution of plant metabolism. [PDF]
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

One Size Fits All? Molecular Evidence for a Commonly Inherited Petal Identity Program in Ranunculales [PDF]
Petaloid organs are a major component of the floral diversity observed across nearly all major clades of angiosperms. The variable morphology and development of these organs has led to the hypothesis that they are not homologous but, rather, have evolved

Phylogeography of a Tertiary relict plant, Meconopsis cambrica (Papaveraceae), implies the existence of northern refugia for a temperate herb [PDF]
The perennial herb Meconopsis cambrica, a western European endemic, is the only European species of the otherwise Himalayan genus Meconopsis and has been interpreted as a Tertiary relict species.

A Global Analysis of Alternative Splicing of Dichocarpum Medicinal Plants, Ranunculales
Background: The multiple isoforms are often generated from a single gene via alternative splicing (AS) in plants, and the functional diversity of plant genome is significantly increased. Despite well studied gene functions, the specific functions of isoforms are little known, therefore the accurate prediction of isoform functions is exceedingly wanted.

Fossils of plant–insect interactions are direct evidence of paleoecological relationships between these two dominant groups in terrestrial ecosystems. We present a variety of plant–insect interactions from the late Early Cretaceous (latest Albian) in the
