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 and oscillations of gene expression. The authors describe several models for […]
Insight: Why we need more non-seed plant models 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, but particularly […]

He argues that a richer understanding of plant evolution depends upon gaining insights into the non-seed plants, including ferns, mosses and liverworts, but particularly the different lineages of charophyte algae, some of […]
Chris Martine is a Professor of Biology at Bucknell University. He is also an excellent communicator of plant science, through his YouTube series “Plants are Cool Too“. In 2016 he was awarded the New England Biolabs Passion in Science Award. You can see him talk about his science communication efforts in this short talk presented […]
Mike Blatt, Editor-in-Chief of Plant Physiology, was recently interviewed for the “People Behind the Science” podcast series. Read excerpts and hear the full interview here http://www.peoplebehindthescience.com/dr-mike-blatt/#more-5509.
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 provide infection opportunities for […]
Fultz and Slotkin explore the question of how transposable element (TE) silencing is initiated. As they describe, there are two recognized mechanisms, one based on TE identity (meaning that it can be silenced through siRNAs initiated from a related TE, and in which de novo silencing can occur in the absence of mRNA production), and […]
Familiar citrus fruits such as sweet orange, lemon, lime and grapefruit are hybrids of three species: Citrus reticulate (mandarin), C. medica (citron), and C. maxima (pummelo). Cultivated varieties are generally vegetatively propagated, with diversity arising from spontaneous or induced somatic mutations. Butelli et al. previously showed that anthocyanin accumulation in sweet orange is correlated with […]
Plant growth chambers are indispensable for most plant science researchers, but of course they do not replicate the outdoor environment. Vialet-Chabrand and Matthews et al. explore the effect of realistic, dynamic fluctuating light (for example as influenced by clouds and leaves) versus light provided in more static conditions (square wave). Plants grown under fluctuating light […]
