The very earliest step in lateral root formation is “priming”, a still-elusive process that establishes a subset of cells as competent to form lateral roots. In this Perspective, ten Tusscher and Laskowski review  evidence for priming, which involves oscillations of auxin level or responsiveness…

There is much to be learned from comparing plant genomes, but as Rensing writes, currently available genomic data are skewed heavily towards angiosperms. He argues that a richer understanding of plant evolution depends upon gaining insights into the non-seed plants, including ferns, mosses and liverworts,…

IN BRIEF by Jennifer Mach [email protected] To navigate its essential function of producing mRNAs, RNA polymerase II (Pol II) must navigate the thread of DNA, which winds around thousands of nucleosomes. If you’ve ever tried to use a sewing machine but got your bobbin thread tangled, then the task faced…

Hydathodes are the sites of guttation, which is a process by which water and solutes are pushed out of leaves by the force of root pressure when the rate of transpiration is low (for example at night).  Hydathodes have numerous stomata-like pores and are located near vascular ends. Like stomata, hydathodes…
