The Saururus chinensis genome provides insights into the evolution of pollination strategies and herbaceousness in magnoliids. [PDF]
Saururus chinensis, an herbaceous magnoliid without perianth, represents a clade of early-diverging angiosperms that have gone through woodiness-herbaceousness transition and pollination obstacles: the characteristic white leaves underneath inflorescence

Phylogenomic discordance is driven mainly by pervasive ancient hybridization and incomplete lineage sorting during the early divergence of major angiosperm lineages. [PDF]
Most extant angiosperms belong to Mesangiospermae (eudicots, monocots, magnoliids, Chloranthales, and Ceratophyllales). Resolving the evolutionary relationships among these five lineages is essential for understanding the early diversification of ...

Is there silicon in flowers and what does it tell us? [PDF]
Whether flowers accumulate Si and what the implications may be was largely unknown. We analysed the flowers separated into their different anatomical parts, and leaves of different taxa. We conclude that flowers contain Si, in large amounts for some species, and hence the function of this element warrants more attention.

Dissecting mitogenomic conflict to illuminate angiosperm deep phylogeny: Sequence and architectural evidence [PDF]
Deep relationships in the angiosperm tree of life remain highly controversial. To address this, we first assembled the complete mitochondrial genomes for Ceratophyllum demersum and Chloranthus sessilifolius, confirming a well-supported sister ...

Ecology and Evolution of Gall-Inducing Arthropods: The Pattern From the Terrestrial Fossil Record
Insect and mite galls on land plants have a spotty but periodically rich and abundant fossil record of damage types (DTs), ichnotaxa, and informally described gall morphotypes.

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti‐herbivore defenses, selection for qualitative toxins, and acceleration of plant–herbivore coevolution [PDF]
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

First genome and transcription factor profile for Asimina triloba, a native North American fruit tree [PDF]
Abstract Pawpaw (Asimina triloba) is the only fruit‐producing tree of the soursop (custard apple) family Annonaceae that is native to temperate North America. Pawpaws are extensively cultivated in the northeast United States, but to date, there are few genetic resources and no publicly available genome assemblies.

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‐

The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究
Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...
