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…

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,…

Cultivation of Tulipa gesneriana (tulip), an economically important species due to its ornamental value, can be affected by warming winters, leading to low quality flowers produced out of season. Leeggangers et al. have sequenced RNA and used top-down and bottom-up approaches in tulips grown in two contrasting…

Where do flowers come from? Their sudden appearance and rapid radiation was described as an “abominable mystery” by Charles Darwin. Ruelens et al. examine the genetic toolkit that underpins reproductive organ formation in gymnosperms to uncover the origins of flowers (which they pragmatically describe…
