Review: 3D electron microscopy for imaging organelles in plants and algae (Plant Physiol)

Have you noticed that the quality and resolution of cell images has been getting better and better? Weiner et al. review the recent advances in 3D electron microscopy (EM) technologies that have provided these strikingly beautiful and informative images. Like “classic” transmission EM, EM tomography requires the production of thin sections, either through cryo-preservation (Cryo-EM) […]

Review: Illuminating the hidden world of calcium ions in plants with a universe of indicators (Plant Physiol)

Calcium ions (Ca2+) are ubiquitous and essential signals, with a very steep concentration gradient from outside to inside the cell. Numerous studies from across the kingdoms have demonstrated that transient Ca2+ fluxes convey information of many types. Here, Grenzi et al. provide an Update on the tools that have been developed to quantify and localize […]

Review: The long road to engineering durable disease resistance in wheat (Curr. Opin. Biotechnol.)

This review by Wulff and Krattinger is a beautifully written “must read”. As the title suggests, it takes the reader on a journey of scientific progress, starting from the “first controlled cross between two wheat species” to the present, with a look into the future. Triticum aestivum (bread wheat) is a critically important food crop […]

Lessons on textile history and fibre durability from a 4,000-year-old Egyptian flax yarn (Nature Plants)

“Food, fuel, and fiber” sometimes is used to describe our utter dependence on plants, but often, other than cotton, the “fiber” part is under appreciated. However, there is a growing interest in bio-based materials, both for their greater recyclability and as an alternative to petroleum-derived materials (see ‘Biobased Composites for Mobility and Transportation: Moving towards […]

Review: Bryophytes as model systems for studying evolutionary cell and developmental biology (Plant Cell)

The development of Arabidopsis as a model system greatly advanced the field of plant cell biology by bringing in molecular approaches, so much of our conceptual foundation rests on studies from angiosperms. More recently, model bryophytes, particularly Marchantia polymorpha (liverworts) and Physcomitrium patens (mosses) have provided additional insights, as discussed in this review by Naramoto […]

Review: Fifteen compelling open questions in plant cell biology As part of The Plant Cell’s upcoming celebration of plant cell biology, Roeder et al. write about fifteen of the “open questions” in the field. This, and the other reviews that make up the focus issue, provide valuable insights into the leading edge of the discipline. […]
