Stretching Plants with Cellular Resolution

Robinson et al. develop a method to measure mechanical properties of plant tissue with cellular resolution https://doi.org/10.1105/tpc.17.00753 Background: Plant growth is controlled by the extensibility of the cell wall and the turgor pressure inside. The spatial regulation of these properties…

Transcriptional Switching Makes New Messages

Fukudome et al. explore the significance of Pol II C-terminal phosphorylation https://doi.org/10.1105/tpc.17.00331 By Akihito Fukudome and Hisashi Koiwa Background: In animals and plants, gene expression begins with an enzyme called RNA polymerase II (Pol II), which produces ribonucleic acid (RNA)…

Multiple Mediator Subunits Impact Metabolism

Dolan et al. examine how a complex that regulates gene expression alters the production of phenylpropanoids  https://doi.org/10.1105/tpc.17.00282 By Whitney Dolan and Clint Chapple Background: Plants produce a vast array of compounds known as phenylpropanoids from the amino acid phenylalanine.…

Schmitz et al. investigate the physiological significance of the glyoxylase system  in Arabidopsis https://doi.org/10.1105/tpc.17.00258 By Jessica Schmitz and Veronica G. Maurino BACKGROUND: In every living cell, side reactions of enzymes and spontaneous reactions of metabolites inevitably…

Axis of Algae: Disruption of Basal Cell Fates in the Brown Alga Ectocarpus

Polarization may be bad for civil discourse, but sometimes polarization can be good—for example, if you’re a multicellular organism setting its body axes. In many organisms, polarity within the zygote sets the stage for an asymmetric cell division that defines the apical-basal polarity of the developing…

OnGuard2 Computational Platform Tracks Guard Cell Processes

Wang et al. discover unexpected connections between humidity and ion transport using a model that bridges guard cell-to-leaf scales https://doi.org/10.1105/tpc.17.00694 By Maria Papanatsiou Background: Plants rely on stomata on the leaf epidermis for their survival. Stomata are small pores formed…

How Signals in Plant Leaves Influence Flowering

Brambilla et al. describe antagonistic signals in rice leaves that control flowering https://doi.org/10.1105/tpc.17.00645 By Vittoria Brambilla Background: A plant’s lifecycle is marked by a major switch occurring when the plant stops producing leaves and starts to make flowers. This switch is…
