Duckweeds: Model organisms for research on plant sterols and steroids. [PDF]
Plant Biol (Stuttg)Duckweeds (Lemnaceae), the fastest‐growing angiosperms and promising vegan protein source, offer a powerful model to address key questions in plant physiology. This article highlights their potential for dissecting the biosynthesis and function of phytosterols, sterol conjugates, brassinosteroids, and specialized steroidal metabolites, such as ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential 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‐

Macroevolutionary dynamics in the transition of angiosperms to aquatic environments. [PDF]
New Phytol, 2022 Summary Angiosperm lineages in aquatic environments are characterized by high structural and functional diversity, and wide distributions. A long‐standing evolutionary riddle is what processes have caused the relatively low diversity of aquatic angiosperms compared to their terrestrial relatives.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]
Am J BotAbstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Target sequence data shed new light on the infrafamilial classification of Araceae
American Journal of Botany, Volume 110, Issue 2, February 2023., 2023 Abstract Premise Recent phylogenetic studies of the Araceae have confirmed the position of the duckweeds nested within the aroids, and the monophyly of a clade containing all the unisexual flowered aroids plus the bisexual‐flowered Calla palustris. The main objective of the present study was to better resolve the deep phylogenetic relationships among ...

Journal of Systematics and Evolution, Volume 61, Issue 1, Page 64-79, January 2023., 2023 A phylogenomic study of Amorphophallus from plastid DNA revealed a new scenario and timeline for the evolution of the main clades, consistent with their morphological characteristics, past climate dynamics, and long‐distance dispersal events across the genus. Abstract Encompassing ca.

The developmental basis of floral nectary diversity and evolution. [PDF]
New PhytolSummary Nectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.

Lords of the biosphere: Plant winners and losers in the Anthropocene
PLANTS, PEOPLE, PLANET, Volume 4, Issue 4, Page 350-366, July 2022., 2022 The impact of humans on Earth's biodiversity varies across the Tree of Life. The extirpation and extinction of species is often determined by compatibility with human activities. Here we classify, where data are available, a significant portion (~30%) of vascular plant species as winners or losers with respect to this compatibility and show that ...

Limnology and Oceanography, Volume 67, Issue S1, Page S38-S53, February 2022., 2022 Abstract Community ecology has had a strong focus on single snapshots of species compositional variation in time. However, environmental change often occurs slowly at relatively broad spatio‐temporal scales, which requires historically explicit assessments of long‐term metacommunity dynamics, such as the order of species arrival during community ...

Plastid phylogenomic analysis of green plants: A billion years of evolutionary history
American Journal of Botany, Volume 105, Issue 3, Page 291-301, March 2018., 2018 Premise of the Study For the past one billion years, green plants (Viridiplantae) have dominated global ecosystems, yet many key branches in their evolutionary history remain poorly resolved. Using the largest analysis of Viridiplantae based on plastid genome sequences to date, we examined the phylogeny and implications for morphological evolution at ...
