Relative fructose content and tomato susceptibility to Botrytis cinerea
Plant defence against Botrytis cinerea, a ubiquitous pathogenic fungus, is known to depend upon the mobilisation of sugars which provide energy and carbon skeletons for the production of antifungal compounds. Lecompte...

Rice resistance responses to the root-knot nematode Meloidogyne graminicola
Meloidogyne graminicola is responsible for production losses in rice (Oryza sativa) in Asia and Latin America. Petitot et al. assess the cytological and molecular mechanisms underlying nematode resistance identified in...
Comparison of winter and summer dormancy in herbaceous perennial species
Are winter and summer dormancy symmetrical seasonal adaptive strategies?
Molecular mechanisms of noise and robustness
Robustness, the inverse of noise, is a molecularly programmed feature of biological systems. The molecular networks of some organismal phenotypes like development are designed to maximize robustness, while other...
Co-ordinated carbohydrate metabolism and hormone synthesis enables plants to survive unfavourable field conditions
Chrysolaena obovata, an aster of the Brazilian Cerrado, presents seasonal growth, marked by senescence of aerial organs in winter and subsequent regrowth at the end of this season. The underground reserve organs, the...

An underground tale: contribution of microbial activity to plant iron acquisition
This review focuses on the possible mechanisms underlying the promotion of plant Fe acquisition by soil micro-organisms.
Another bacterial trick to manipulate plant hormone-mediated responses
A novel example of a bacterial effector directly manipulating core regulators of hormone signaling to facilitate infection.
Mechanisms of signal transduction by ethylene
The gaseous hormone ethylene plays multiple roles in regulating plant growth and development.
Transient VENUS
This year’s transit of Venus reminds me – albeit belatedly – to applaud the hard-working botanists of the Universities of Nottingham (UK), Ghent (Belgium), Leeds (UK) and Lyon (France) who have been exploring a more...

Botany for Halloween – Witches, Brooms and Pumpkins
At the moment, I am teaching plant hormones in our course on plant cell and developmental biology (BS1003). Fortunately, hormones and development link well with Halloween this year: we have witches, sitting on a broom...
