The jigsaw-puzzle shape of the epidermis layer has been puzzling the scientists for some time now. Majda et al. examine the shape of the epidermis cells from the cell wall perspective. Mutations leading to even minor changes in cell wall composition significantly affected pavement cell geometry.…

Genetic screens have revealed many key components of light signaling. In this new work, Sinclair et al. provide new insights into the repression of photomorphogenesis by cell-wall derived signals. They started with a mutant, de-etiolated by zinc (dez) that shows open cotyledons and a short hypocotyl…

The trade-off between grain size and number has been traditionally hard to break.  Bai et al established that differences in panicle architecture between two rice cultivars resulted from duplication of a long-distance silencer of the FRIZZY PANICLE (FZP) gene in one cultivar (Chuan 7).  Increased silencing…

Plant roots constantly engage in nutrient and water uptake for crop productivity. Increasing the nutrient uptake efficiency of roots will promote sustainable agriculture by decreasing the need for fertilizer applications. To achieve this task, we need to understand the physiology of intact roots in their…

While much is known about the processes involved in stomatal movement and the processes involved in the transpiration of leaves, there has been no framework to bridge this micro-macro divide. Wang and colleagues bridge this divide through OnGuard2, a quantitative systems platform that uses the molecular…

How do plants ‘decide’ how to respond to so many conflicting stimuli? What has the final say in stomatal aperture control? Hassidium et al. investigate the role of the oscillator gene CIRCADIAN CLOCK ASSOICATED 1 (CCA1) during stomatal opening and determined if CCA1 is responsive to other stimuli.…

If you ever tried to compare the results from two different experiments, you probably realized that small variations in the environment have big impact on how the plants grow. There is a lot to be learned from how the variation in the environment affects plant phenotypes, but currently the description…

Review: Growth-mediated plant movements: hidden in plain sight ($) Time-lapse imaging reveals the slow movements of plants, such as phototropism and gravitropism. Harmer and Brooks review the molecular bases for these growth-mediated movements. While auxin has long been known to be involved in photo-…
