      Homage to a nanotubule…

      Frequently, journals will devote a whole issue to a particular theme, maybe even to a single species (even whole journals are seemingly devoted to Arabidopsis thaliana…). But rarely will they be devoted to a single journal article. Well, such is the power of ‘Ledbetter and Porter (1963)’ that the July 2013 issue of the Plant […] More

      Waste not, want not…

      A little while ago we looked at auxotrophic algae getting a helping hand from bacteria; now we’ll take a look at ‘proper plants’ that get a little help from animals (in a sort of mixotrophy). But it’s not exactly willing on the animal’s part! We talk of those amazing angiosperms known as carnivorous plants (‘the […] More

      The Vacuole: not just an empty hole!

      The vacuole is the largest organelle of a plant cell. It accumulates proteins, ions and secondary metabolites while providing turgor for cell growth via water content. It is also a major site for the degradation of macromolecules. A full understanding of the vacuole’s roles in salt and metal ion accumulation and water uptake are hot […] More

      Free paper — Dividing without centrioles

      Innovative MTOCs organize mitotic spindles in bryophytes, the earliest extant lineages of land. Triple staining of γ-tubulin, microtubules, and nuclei here reveal that three types of MTOCs initiate spindles in bryophytes. Polar organizers in liverworts and plastid MTOCs in hornworts are unique and nuclear envelope MTOCs in mosses appear like those in seed plants. Roy C. […] More

      Plant cell biology in the frame!

      Notwithstanding the centuries we’ve spent peering at, poking, prodding and penetrating the inner workings of plant cells with various types of microscopes and decades undertaking investigations at the sub-cellular level, there are still new discoveries to be made. Here are two, united by the theme of cell–cell transport. First, the recent revelation by Deborah Barton […] More
