Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

Fine Tuning Floral Morphology: MADS-Box Protein Complex Formation in Maize

Plant floral organ development is orchestrated by master regulatory genes that control the differentiation of meristem tissue. According to the ABC(DE) model of flower development (Bowman et al., 1989; nicely summarized by Irish, 2017), different floral organs form in concentric whorls (verticils) in…

MYB30 links the ROS wave to systemic acclimation

The photobiology paradox resolved: photoreceptors drive photosynthesis and vice-versa

Charlotte Gommers, Assistant Features Editor charlotte.gommers@wur.nl For a long time, the study of light fueled two independent fields of plant sciences. On the one hand, light energy is absorbed in the chloroplasts, to drive sugar production via photosynthesis. On the other hand, light is an…

True Blue: How Cry1 Inhibits Phototropism in Green Seedlings

Kasper van Gelderen Plant Ecophysiology, Dept. of Biology, Utrecht University, Padualaan 8 3584CH, Utrecht, The Netherlands. The study of plant movement towards light, also called phototropism, has a venerable history with giants such as Charles Darwin and Frits Went involved in its study, which…

Sugars Inform the Circadian Clock How to Shape Rice Shoots via the Strigolactone Pathway

Circadian clocks act as universal timekeepers to harmonize internal processes with external day-night rhythms. Genetic feedback loops gear these inner clocks by approximating time in response to dawn-dusk cycles. In plants, development, growth, hormone action, metabolism and other downstream events are…
