Plasmodesmata are pores between cells through which viruses, proteins, small RNAs and other molecules can pass. The pores are usually described as being lined with a layer of plasma membrane with a tube of endoplasmic-reticulum membrane through the center. These membranes and associated proteins are…

In the symbiotic relationship between arbuscular mycorrhizal fungi and plants, the fungal partner greatly enhances the uptake of mineral nutrients (particularly phosphate), while in return it is supplied with organic carbon from the photosynthetic partner. Luginbuehl et al. investigated whether this…

Li et al. describe an important new genetic resource, a huge database of Kitaake rice mutants. Kitaake is a short-generation variety of Oryza sativa L. ssp. japonica well suited for genetic studies. The authors sequenced more than 1500 fast-neutron-induced mutants and identified more than 91,000 mutations…

Plants, like human societies, must live with the inherent conflict between investing in defense and investing in growth and infrastructure. Burrow and Halkier provide an interesting and highly readable overview of the strategies by which Arabidopsis optimizes the production and distribution of glucosinolates,…

Review: How does a plant orchestrate defense in time and space? Using glucosinolates in Arabidopsis as case study Plants, like human societies, must live with the inherent conflict between investing in defense and investing in growth and infrastructure. Burrow and Halkier provide an interesting and…

By Fulton E. Rockwell, and N. Michele Holbrook The structure of leaf vasculature viewed over a broad phylogenetic scale from lycophytes to eudicots correlates with stomatal conductance (gs), providing the basis for the hypothesis that increasing vein density drove the evolution of high fluxes in angiosperms.…
