    Arbuscular mycorrhizal growth responses and phosphorous efficiency in soybean genotypes

    Arbuscular mycorrhizal (AM) fungi play a key role in phosphate (P) uptake of many crop species, but the mechanisms by which P uptake in the AM symbiosis is controlled are only poorly understood. Wang et al. examined the effects of the phosphate acquisition efficiency (PAE) of soybean plants on P uptake and transport via the […] More

    Legume genomics and next-generation sequencing (Invited Review)

    The legume family (Leguminosae) consists of approximately 17 000 species and those used as crops provide protein and carbohydrates for over 300 million people world-wide. O’Rourke et al. review how next-generation sequencing technologies and associated bioinformatic analyses have allowed individual researchers to assemble genomes, identify gene-coding regions and study gene expression patterns. To illustrate the power of […] More

    Leaf hydraulic conductance at elevated [CO2] and temperature

    Leaf hydraulic properties are strongly linked with transpiration and photosynthesis in many species, but it is not known if gas exchange and hydraulics will have co-ordinated responses to climate change. Locke et al. study soybean (Glycine max) and find that leaf hydraulic conductance (Kleaf) does not change for plants grown at elevated [CO2] or elevated […] More

    The role of ROS in soybean seed germination

    Reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), can promote seed germination in a number of species but their role in soybean has not been fully determined. Ishibashi et al. use the anti-oxidant N-acetylcysteine to counteract the effects of ROS in germinating seeds of soybean, Glcine max, and study endogenous ethylene content, the number and […] More

    Purple acid phosphatase genes in soybean

    Purple acid phosphatases (PAPs) are members of the metallo-phosphoesterase family and have been known to play important roles in P acquisition and recycling in plants. Li et al. identify 35 PAP genes from genomes of soybean, Glycine max, and use quantitative real-time PCR to analyse the expression patterns in response to P deficiency and symbiosis. They […] More

    Novel border-like cells in woody plant roots

    Novel border-like cells in woody plant roots Root border cells play a critical role in root growth and microbial association, although their detachment patterns are divergent among plant species. Endo et al. describe a detailed pattern of synthesis, separation and survival of distinct border-like cells that form a sheath surrounding the root apex of a tree, […] More

    Hourglass cell development in soybean seed coat

    Hourglass cells (HGC) are prominent cells in the legume seed coat. Miller et al. (pp. 235–242) document HGC development in soybean, Glycine max, and relate structural changes to expression of an HGC-specific soybean peroxidase (SBP). SBP protein and activity are detectable in HGCs before differentiation is complete; furthermore, activity appears vacuolar, as predicted. These results […] More
