Auxin is involved in a diverse array of developmental processes as well as biotic and abiotic stress responses. The chemical–genetic approach is a powerful tool to decipher the auxin signaling pathway. In this review, Fukui and Hayashi have provided a comprehensive overview about the structure, molecular…

This article is the second of three and is based on a workshop called “Reproducibility for all” presented at PlantBio18 by Benjamin Schwessinger, Sonali Roy, and Lenny Teytelman. In Part 1 (here), the authors describe the importance of having a data management plan, and the value of electronic notebooks. 3.…

Looking at a typical plant, you may not notice that it is moving. Although generally perceived as static, all plants are dynamic, as shown by time-lapse photography.  Plant Tracer is the first App-based tool that enables students and scientists to quantify plant movement (circumnutation and gravitropism)…

There are pros and cons to growing plants in controlled conditions. On the one hand, controlling light, temperature, humidity and other environmental factors should aid reproducibility between experiments and labs. But what if the conditions used profoundly and unexpectedly affect the process you are…

Stomatal opening is stimulated by light, including blue and red light. Blue light-induced stomatal opening is fairly well understood: it is mediated by blue-light photoreceptor phototropins (phot1 and phot2). Blue light activates the plasma membrane (PM) H+-ATPase via phosphorylation of its penultimate…

The study of phloem transport and its vital roles in long distance communication and carbon allocation have been hampered by a lack of suitable tools that allow high-throughput, real-time studies. Since the 1970s, several studies have used 11C or 14C isotopes to measure rates of phloem transport in large…

Protein-protein interactions mediate fundamental biological processes. Yeast two-hybrid assays can be used to detect protein-protein interactions in a fast and large-scale manner. However, in traditional yeast-two hybrid assays, the prey and bait proteins must be located in the nucleus to activate reporter…

Auxin has been studied since Charles Darwin observed the phototropic response. More recently, chemical genetic approaches using auxin agonists and antagonists have been applied to studies of auxin. Torii et al. review how synthetic chemistry and chemical genetics have provided insights into and new tools…
