Synthetic biology aims to engineer and redesign components of natural organisms for useful purposes.  One of the most prolific areas of synthetic biology is based on the engineering of photoreactive proteins with signaling potential, such as photoreceptors. Natural photoreceptors consist of a prosthetic…

The vascular plant body composed of root and shoot is specified during embryogenesis, but most flowering plants can also develop additional root systems post-embryonically: lateral roots, as a response to wounding, or shoot-borne roots (“adventitious” roots, literally meaning “in the wrong place”).…

Generally, evolution is driven by natural selection, but not always. Human activities lead to the creation of unique niches, and other organisms must adapt accordingly. Cities are unique niches that are significantly different from rural areas and natural conditions. The urban habitat provides plants…

The seed germination niche is the set of environmental conditions in which a seed can germinate. This collection of requirements is expected to be tuned to the climate each species encounters in its natural habitat, but this hypothesis remains to be formally tested. Here, Carta and colleagues make use…

Seed dormancy is widely recognized as a key mechanism to ensure that germination takes place under the most suitable conditions. Such is its importance that multiple studies have described the morphological, physiological, and genetic mechanisms behind it, yet its global distribution and the past and…

NLPs (Necrosis and ethylene-inducing peptide 1–like proteins) are small peptides produced by a variety of plant pathogens. Some NLPs are cytolysins meaning that they trigger lysis of their target cells. Here, Pirc et al. use an assortment of tools including molecular dynamics (MD) simulations, neutron…

Live Plant Cell Tracking: A Fiji plugin to analyze cell proliferation dynamics and understand morphogenesis Morphogenesis in plants occurs in 3D space over time, referred to as 4D. Recent advances in high-resolution microscopy imaging and computational pipelines have helped to better understand…

Chloroplast protein import determines plant proteostasis and retrograde signaling The neurological condition Huntington’s disease is caused by mutated versions of the Huntingtin gene that encode expanded stretches of polyglutamine repeats, resulting in protein aggregation. However, despite the widespread…
