Genetic and morphological signature of ancient Agave cultivation
Parker et al. test whether formerly cultivated Agave parryi populations still bear a predictable genetic and morphological signature.
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.
Nutrient stoichiometry and resorption in karst vegetation
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.
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.
Unidirectional hybridization in heterostylous primroses
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.
Regulation of a Solanum Double-B box gene
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.
