Nitrate uptake modelling in plants: root activity
Using a thermodynamic flow–force interpretation of nitrate uptake isotherms, Malagoli and Le Deunff develop a functional– structural model to predict N uptake in winter oilseed

Nitrate uptake modelling in plants: functional components
Difficulties in linking the various regulations of nitrate transport acting at different levels of time and on different spatial scales have hindered the development of models

Selection on a CONSTANS-like gene between two red oaks
Oaks can provide a model to study hybridization as they often maintain species integrity and distinct environmental adaptations despite recurrent gene flow. Lind-Riehl et al.

Temperature and reproductive success in arabidopsis
Seed yield and dormancy status are key components of species fitness that are influenced by the maternal environment. Huang et al. grow the Arabidopsis thaliana ecotype

Predicting mixed-species litter decomposition
Tardif et al. measure decomposition rates of litter from four herb species at three sites along a correlated climatic gradient of temperature and precipitation in order to test the predictive value of the hypothesis.

Fibre cables and tensegrity in Typha leaves
Witztum and Wayne dissect leaves of various species of Typha, and examine the fibre cables – composed of long, non-lignified cells – that traverse the air chambers (lacunae).

BcMF8 contributes to pollen wall development and tube growth
Lin et al. examine expression of Brassica campestris male fertility 8 (BcMF8) in pistils of Chinese cabbage (B. campestris ssp. chinensis), and find that it encodes a putative AGP that is located in the cell wall and is expressed in pollen grains and pollen tubes.
