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...

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...

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...

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...

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...

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...

Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...

What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...
