Review: On the selectivity, specificity and signaling potential of long-distance movement of messenger RNA
Regulation of transcription occurs at the cell-type specific level, but transcribed messenger RNA is mobile and can move between tissues through plant vasculature, serving as a long distance…
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…
How Plants Clear Toxic Proteins
Gil et al. explore ZTL-mediated protein quality control https://doi.org/10.1105/tpc.17.00612
By Kyung-Eun Gil
Background: As sessile organisms, plants have evolved various mechanisms to adapt to environmental changes. Under stressful conditions such as high temperatures, proteins are misfolded…
Broad-Spectrum Disease Resistance in Tomato
Broad-Spectrum Disease Resistance in Tomato
Zhu et al. examine how a plant receptor protein confers broad-spectrum resistance to various tospovirus pathogens https://doi.org/10.1105/tpc.17.00180
By Min Zhu, Savithramma P. Dinesh-Kumar, and Xiaorong Tao
Background: Highly evolved microbes cause…
Funding Opportunity: 2018 Botany in Action Fellowship
The Phipps Conservatory and Botanical Gardens (Pittsburgh, PA) 2018 Botany in Action Fellowship program is currently accepting proposals for this unique fellowship, which fosters the development of the next generation of plant-based scientists who are committed to both excellent research and educational…
Point of View: A transatlantic perspective on 20 emerging issues in biological engineering studies
“Horizon scanning” describes the process of trying to rationally predict the future. Wintle et al. describe the results from a horizon-scanning exercise to identify emerging issues in biological engineering. The authors used an iterative approach to identify key issues in the near and longer-term…
Plant RuBisCo assembly in E. coli with five chloroplast chaperones ($)
In plants, Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCo), the enzyme responsible for fixing carbon, is a made up of 8 each of the large and small subunits, making the L8S8 form. Efforts to study this enzyme have been thwarted by the inability to assemble an active L8S8 form in a heterologous…
Review: The role of water in plant-microbe interactions ($)
Water, a principal component on earth has also a fundamental role in maintenance of plants, microbes and the disease that is shaped by such interaction. Pathogenic disease outbreaks occur only in favorable environmental conditions, and atmospheric humidity is essential for pathogenesis. This review by…
