Stamen movements and pollination in Ruta
In Ruta graveolens each stamen elevates to above the flower’s centre for anther dehiscence and then falls back before the next stamen elevates, producing a

COR, nice one, Mr Microbe!
Although open stomata are necessary for plants to take up CO2 for photosynthesis, this also permits loss of precious water – by transpiration, the so-called necessary

Stomatal distribution and stem tracheid dimensions
Leaf and wood plasticity are key elements in the survival of widely distributed plant species. Locosselli and Ceccantini study the variation of stomatal distribution in leaf

Vital amines
Notwithstanding plants’ rightly applauded self-sufficiency, and remarkable life-sustaining synthetic abilities using basic inorganic ingredients, some plant-like organisms need a little extra help in

Dehydration rate and ROS production in an aquatic moss
Desiccation induces an increase of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes as cellular water content decreases. Cruz de Carvalho et al. examine how

Trunk epicormics and growth in Fagus sylvatica
Epicormic shoots in European beech, Fagus sylvatica, may be associated with decreased radial growth. Colin et al. study the number of axillary buds, shoot length, ring

Cytotype distribution in a diploid/hexaploid contact zone in Aster
A knowledge of cytotype diversity and distribution patterns is important in understanding evolutionary dynamics of diploid–polyploid contact zones. Castro et al. study large- and small-

The origin of the sporophyte shoot (Viewpoint)
The long-held notion that the sporophyte shoot is homologous with the seta of mosses has been questioned, but no alternative evolutionary model has hitherto been

Functional classification of olive pollen esterases
Pollen grains contain numerous hydrolytic enzymes, many of which are released upon contact with the stigma. Rejón et al. carry out for the first time a
