Here Comes the Sun: Xanthophylls as Components of Plant Memory. [PDF]

Physiol Plant
ABSTRACT It has been proposed that the de‐epoxidation state of the xanthophyll cycle (AZ/VAZ) represents a mechanism of light memory storage in plants as it depends on the amount of light previously received by the leaf, later affecting the photosynthetic responses by modulating the rate of non‐photochemical quenching (NPQ).

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous-Paleogene boundary in western North America. [PDF]

Am J Bot
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Informing indicator species selection by combining species associations and environmental responses. [PDF]

Ecol Appl
Abstract Biodiversity is changing at an unprecedented pace, underscoring the need for effective and scalable ecological monitoring. Yet selecting which species to monitor remains a major challenge. Indicator species can offer cost‐effective proxies for broader biodiversity trends, but there is a critical gap in robust, data‐driven approaches to ...

Sexual and Apogamous Species of Woodferns Show Different Protein and Phytohormone Profiles

Frontiers in Plant Science, 2021
The gametophyte of ferns reproduces either by sexual or asexual means. In the latter, apogamy represents a peculiar case of apomixis, in which an embryo is formed from somatic cells.
