Auxin response and PIN‐mediated transport in chlorophyte algae

open access: yesJournal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Schmeissneria: A missing link to angiosperms?

open access: yes, 2007
Background The origin of angiosperms has been under debate since the time of Darwin. While there has been much speculation in past decades about pre-Cretaceous angiosperms, including Archaefructus, these reports are controversial.

Visualising Physcomitrium patens protoplasts with full‐rotation soft X‐ray tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract Soft X‐ray tomography (SXT) is a label‐free, high‐resolution imaging modality that is optimal for 3D visualisation of whole hydrated cells. Although SXT has been extensively used to study remodelling in more than 130 mammalian cell lines, its application to plants remains largely unexplored. In this study, we present the first approach at full‐

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Patent landscape analysis of inventions based on plant genetic resources for food and agriculture and related digital sequence information

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract This article provides an overview of the patent landscape in relation to PGRFA‐based inventions involving naturally occurring (“native”) traits and related Digital Sequence Information/Genetic Sequence Data (DSI/GSD). In particular, it focuses on the potential of patent claims to limit others' uses of PGRFA and related DSI/GSD on which the ...

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

open access: yesNew Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.
