Review: Recent discoveries show novel sensors and regulation of reactive oxygen species (Nature Plants)

Reactive Oxygen Species (ROS) are produced as metabolic byproducts and are vital participants in development and stress responses. However, ROS can be damaging, and are subcellularly localized to mitigate toxicity. Perception of pathogen attack leads to apoplastic ROS production through Respiratory Burst…

Review: One cell, many signatures: Organellar Ca2+ signaling (Plant Physiol.)

Calcium ions (Ca2+) occupy a primary position in plant cell signaling processes by virtue of their role…

Review: Chronoculture: improving crop yield and sustainability by exploiting the plant circadian cycle ($) (Science)

The circadian cycle affects almost all eukaryotic cells. In the case of plants, circadian rhythms affect…

Review: Postzygotic reproductive isolation established in the endosperm: mechanisms, drivers and relevance ($) (Phil. Trans. R. Soc. B)

In this fascinating review, Köhler and colleagues show us that the seed endosperm is not only a nutritive…

Review: Ageing beautifully: can the benefits of seed priming be separated from a reduced lifespan trade-off? (J. Exp. Bot.)

Seed priming is a family of presowing techniques that control water uptake in seeds, so they are dehydrated…

Viewpoint: Bryophytes are not early diverging land plants (New Phytol.)

Phylogenetic trees demonstrate the evolutionary relationship between organisms, but sometimes these relationships…

An evidence-based 3D reconstruction of Asteroxylon mackiei, the most complex plant preserved from the Rhynie chert (bioRxiv)

The Rhynie chert holds some of the oldest and best-preserved fossils of vascular plants (Rhynie is a…

Trapped in traffic – redefining cellular responses to auxin pharmacology (Plant Physiol.)

Understanding cellular responses to the phytohormone auxin has always been a challenge and decades of…

Structural insights into photosystem II assembly (Nature Plants)

Photosystem II is a multisubunit enzyme complex in the thylakoid membranes of plant, algae, and cyanobacteria.…

DELLA degradation by gibberellin promotes flowering via GAF1-TPR-dependent repression of floral repressors in Arabidopsis (Plant Cell)

In Arabidopsis, flowering is promoted by the activation of the florigen FT in response to long days and…

Pollen PCP-B peptides unlock a stigma peptide–receptor kinase gating mechanism for pollination (Science)

It’s spring where I live and the air and my eyes are filled with pollen. The lucky few pollen grains…
