Parker et al. test whether formerly cultivated Agave parryi populations still bear a predictable genetic and morphological signature.

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.

Liu et al. examine the relationships between resorption patterns of 13 nutrients and leaf nutrient status in eight plant functional types in the karst region of south-western China.

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).

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.

Ma et al. study a natural hybrid zone between two heterostylous primrose species, Primula beesiana and P. bulleyana, and find that all hybrid derivatives examined are backcrosses of first or later generations to P. bulleyana, and have the cpDNA of that species.

Kiełbowicz-Matuk et al. investigate variations in a Solanum DBB protein, SsBBX24, in S. tuberosum and S. sogarandinum and find evidence of trafficking from the nucleus to the cytosol during the light period.

Robert et al. monitor stem variations in A. marina trees in a natural mangrove forest over the course of one year, and find that patchiness occurs in both the radial growth and the shrinkage and swelling patterns of the stems.
