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…

Olivier Godfroy is featured first author of DISTAG/TBCCd1 Is Required for Basal Cell Fate Determination in Ectocarpus Current Position: Research assistant in the Translational Gene Therapy group, Nantes Hospital Education: PhD in Plant Biotechnologies at the National Institue of Agriculture Research…

Yan et al. searched for proteins that regulate the delivery of the micronutrient copper to flowers to ensure successful reproduction https://doi.org/10.1105/tpc.17.00363 By Jiapei Yan, Ju-Chen Chia, and Olena Vatamaniuk Background: Global food security and the demand for high-yielding grain crops…

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)…

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…

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…

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…
