Review. Under siege: virus control in plant meristems and progeny Perhaps, when our lives have been turned upside down by a human pathogenic virus, it’s easy to overlook the fact that plants too suffer from viral infections; but of course, they do. (And of course, famously, viruses were first discovered in plants). Although it is […]
Review: Recent discoveries show novel sensors and regulation of reactive oxygen species 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 Oxidase […]
The Rhynie chert holds some of the oldest and best-preserved fossils of vascular plants (Rhynie is a village in north-east Scotland, and chert is a type of sedimentary rock). Analysis of thin section of fossils from here have provided the earliest cellular details of “rhizoid-based rooting systems, germinating spores and fossilised meristems.” But as Hetherington […]
It’s spring where I live and the air and my eyes are filled with pollen. The lucky few pollen grains that land on the stigmatic surface of a flower might germinate and deliver the sperm to the ovule, but there are many checkpoints even after their safe landing. Here, Liu et al. uncover one of […]
Parasitic plants can completely wipe out a farmer’s harvest. The seeds can lie dormant in soil until they perceive signals from potential host plants, which stimulate germination. Therefore, germination stimulants applied to fields before the crops are planted can cause the parasitic seeds to germinate and die in the absence of their host. Many compounds […]
Review: Ageing beautifully: can the benefits of seed priming be separated from a reduced lifespan trade-off? Seed priming is a family of presowing techniques that control water uptake in seeds, so they are dehydrated once metabolic activities have restarted but before the end of germination. Primed seeds have shown increased and more synchronized germination, especially […]

Plantae Presents: Jim Birchler, Evan Forsythe, and Tom Jacobs Special Event: The Plant Cell Focus Issue on the Biology of Plant Genomes Recorded Wednesday, April 21st Advances in genome sequencing have yielded insights into aspects of plant biology; elucidating the course of evolutionary history; uncovering novel metabolic pathways defining transcriptional complexity; and serving as the […]
We don’t need to remind you of the tremendous positive impact that CRISPR-based technologies have had on the life sciences through enabling any gene to be edited precisely. Here, Gaillochet et al. provide an up-to-date review of a lesser-known application of CRISPR, its use in large-scale screening strategies. The authors start with a refresher in […]
