Molecular signals for regeneration ($)

Every gardener knows that pulling off a shoot is not sufficient to kill a plant. Plants are able to reprogram cells in order to regenerate missing tissues. Pulling off a shoot removes photosynthetic tissues, but the root responds by activating chloroplasts to take over this role. Kobayashi et al. (Plant Physiol. 10.​1104/​pp.​16.​01368) examine the signals […]

A novel chemical inhibitor of ABA signaling targets all ABA receptors

Chemical genetics is an approach that enables small molecules with specific effects on phenotypes to be identified. Through a screen for small molecules that would reverse the inhibitory effect of ABA on seed germination, Ye et al. identified AA1 (ABA Antagonist 1). AA1 interferes with the interaction between all of the ABA PYR-PYL receptors and […]

Review: Stomatal development in time: the past and the future ($)

Stomata, epidermal pores for gas exchange, first appeared about 400 million years ago. Since then, there has been functional and structural diversification. Qu et al. synthesize the developmental genetics underpinning diverse stomata, spanning from bryophytes through monocots and the astomatous (without stomata) marine angiosperms, as revealed by seagrass. Curr. Opin. Genet. Devel. 10.1016/j.gde.2017.02.001

Meeting Review: Auxin 2016 ($)

Vernoux and Robert discuss research presented at the Auxin 2016 meeting, held in October 2016 on the island of Hainan, China. The result is a nice review of very current research, spanning auxin metabolism and signaling, the role of auxin in development, interactions between auxin and other signals, and modeling and synthetic biology approaches to […]

Careers in Plant Pathology

The British Society for Plant Pathology (BSPP) has created a set of profiles of people with careers in plant pathology. Some are available as webpages and others as PDFs. A few examples: Molecular Plant Virologist Katherine A. Steele Plant Disease Advisor Fiona Burnett Professor of Plant Pathology Matt Dickinson (PDF) Agrochemical Research Scientist Siân Deller […]

Perspective: Periodic lateral root priming: What makes it tick

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 […]

What We’re Reading: February 24

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 […]
