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…

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…

Functional principal component analysis: a robust method for time-series phenotypic data

Molecular breeding relies on careful assessment of phenotypic traits linked to DNA markers so that causal genes can be identified and desirable crop alleles selected. Over the past decade, DNA markers have become abundant with the rapid advancement of next-generation sequencing technology, including…

Sensing Attack: The Role of Wall-associated Kinases in Plant Pathogen Responses

Sam Amsbury Department of Animal and Plant Sciences, Sheffield, UK ORCiD: 0000-0002-2767-9768 s.amsbury@sheffield.ac.uk The physical and chemical barrier provided by the cell wall is one of the first lines of defence for plants against pathogen attack. Plant cell walls provide physical protection…

State Transition Regulation in Chlamydomonas

Ananya Mukherjee University of Nebraska, Lincoln, Nebraska 68588 ORCID ID: 0000-0003-1802-1806 amukherjee3@unl.edu Photosynthetic organisms often face fluctuations in light quality and quantity. Green plants and algae have built-in mechanisms that allow them to adapt to such changes. One…

Stem diameter fluctuations provide a new window into plant water status and function

Author: Robert Skelton rskelton@saeon.ac.za Affiliation: South African Environmental Observation Network, Private Bag X7, Claremont, 7735, South Africa Knowledge of the spatio-temporal dynamics of water storage in plant stems is fundamental to understanding plant physiological function under…

Gaining sugars while sweating, how do leaves regulate their osmolarity?

Guillaume Charrier Université Clermont Auvergne, INRAE, PIAF, F-63000 Clermont-Ferrand, France. guillaume.charrier@inrae.fr Leaves are specialized for the photosynthetic assimilation of atmospheric carbon, but they also are responsible for the transpiration of water into the atmosphere, as…

The Meaning of an End: N-terminal Acetyltransferase NAA50 Controls Plant Growth and Stress Responses

Author: Sjon Hartman ORCID: 0000-0002-6709-6436 Plant Ecophysiology, Institute of Environmental Biology, Utrecht University, Padualaan 8, 3584 CH, Utrecht, The Netherlands  At least 80% of eukaryotic proteins are estimated to undergo N-terminal acetylation (NTA), making it likely that your…
