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,…

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…

It’s easy to visualize how a sheet of cells grows, but how does a sheet of cells form a complex, three-dimensional structure? Rebocho et al. describe how differential growth rates between cell layers and across the growing surface can produce a variety of complex shapes. As a model for shape complexity,…

As automated phenotyping platforms are becoming prevalent, scientists increasingly need to be familiar with tools used to describe and model form and growth. Balduzzi et al. provide an overview of the key concepts used in quantifying and describing plant morphology. They point to the need for a common…

There are more than 25,000 species in the Orchidaceae, the orchid family. Chao et al. have updated and restructured the Orchidstra database, which now houses more than half-a million protein-coding genes from 18 species (12 genera and five subfamilies). Access and explore it at http://orchidstra2.abrc.sinica.edu.tw.…

Marchantia polymorpha (a liverwort) is a living relative of the earliest terrestrial plants. As it has a simple genome and morphology and is readily transformable, it provides a good platform for synthetic biology (see https://www.openplant.org/marchantia/). Delmans et al. have designed an “engineering-oriented”…

For decades, scientists have debated the origin of the strange patterns of grass growth known as fairy circles in the Namibian desert. Photographs show a strikingly regular pattern circles of bare ground surrounded by a ring of grass. One hypothesis is that these patterns form due to the action of insects;…

Climate change could affect agricultural productivity by increasing the number of days with temperatures above 30°C that staple crops like soybean, maize and wheat will experience during a given growing season. Schauberger et al. used nine statistical models to assess future threats to US crops. They…
