Breuil-Broyer et al. show that SUPERMAN is a flower developmental canalization and robustness factor. First, partial dissociation of sexual boundary and flower meristem termination control in the sup allelic series...

The interconnectedness of plant studies
Have you ever wondered how the monthly Plant Cuttings’ collection comes to be? Do you think Mr P Cuttings knows in advance what he’s going to write about each month? He has a notional idea of the items he wants to...

A fresh look at guard cell walls
Arguably, one of the best known ‘structure-function’ relationships in plant biology is the role played by cellulose microfibrils within the walls of the guard cells in stomatal opening. Stomata* are the controllable...
Plants, given a helping hand
I’ve been known to remind my students that just because testing demonstrates presence of e.g. ‘phosphate’ in a soil sample that doesn’t necessarily mean it’s in a form that can be accessed/utilised by plants. And...
It’s all about technique
Techniques are at the heart of understanding in botany (and any science, whether it be an –ology or not *). For, as techniques advance so should our understanding – often to the point of over-turning the ‘truth’ that...
Natural populations of Arabidopsis thaliana differ in seedling responses to high temperature stress
Little is known about adaptive within-species thermotolerance variation in wild plants despite its likely role in functional adaptation at range limits and in predicting response to climate change. In a new study...

Peroxisomes and regulation of ROS/RNS signalling (Review)
Sandalio and Romero-Puertas review the metabolism of reactive oxygen and nitrogen species (ROS and RNS) in peroxisomes and their contribution to the regulation of plant development and acclimation to stress conditions.
Plants are !ӣ$%%!^$ӣ [fill in the missing word]*
Plant Behaviour & Intelligence. Anthony Trewavas. Oxford University Press, 2014 Man is arguably happiest when the ‘natural’ order of all things is maintained and where his own dominion over the natural world...
Plants flex their muscles… [or, Onion feeling the pinch…?]
Could onions peel back the layers of future developments in artificial muscle construction and soft robotics?
Testing models for the leaf economics spectrum with leaf and whole-plant traits in Arabidopsis thaliana
The leaf economics spectrum (LES) is a global set of patterns that describes correlations between functional traits (e.g. carbon assimilation rate, lifespan) that determine terrestrial resource fluxes. Several classes...
Hanging On To Your Date, Avoiding Incest And Not Getting Infected – All In A Day’s Work For Flowers Of The Mustard Family
In the mustard family, which includes the important crop Brassica (rapeseed/canola) and the model plant Arabidopsis, the surfaces of the female stigmatic cells are dry. These cells – on which the pollen grains land...

Iron homeostasis in tomato plants
SlbHLH068, a putative transcription factor, is involved in iron homeostasis in tomato via an interaction with FER.

The European Space Agency goes back to its roots
The roots are Arabidopsis roots. They’ll be flying, along with the rest of the plant, on a parabolic flight to see how they react to zero gravity and hypergravity. Franck Ditengou of the University of Freiburg in...
