Genome editing in maize directed by CRISPR–Cas9 ribonucleoprotein complexes

Svitashev et al. demonstrate a new way to introduce CRISPR-Cas9 reagents into a plant cell, through the biolistic delivery of pre-assembled Cas9-gRNA ribonucleoproteins. This approach was successful in the production of engineered plants, and also demonstrated that this method can be done in a DNA- and selectable marker-free way. Nature Comm. 10.1038/ncomms13274

Metabolic Signaling Regulates Alternative Splicing during Photomorphogenesis

IN BRIEF by Kathleen L. Farquharson kfarquharson@aspb.org Alternative splicing (AS) regulates gene expression and greatly expands the coding capacity of complex genomes. By regulating which elements of an mRNA transcript are removed or retained, AS produces multiple transcripts from a single gene. Some of these transcripts contain a premature termination codon (PTC) and are targeted […]

Do Phytochromes and Phytochrome-Interacting Factors Need to Interact?

IN BRIEF by Nancy R. Hofmann nhofmann@aspb.org A new study calls into question whether phytochrome B (phyB) must directly interact with phytochrome-interacting factors (PIFs) to promote light responses. Phytochrome photoreceptors mediate responses to red light in part by inducing the degradation of PIF transcription factors, which generally are repressors of light responses (reviewed in Jeong […]

Recently, we’ve been profiling first authors of Plant Cell papers that are selected for In Brief summaries. Here are the first-author profiles from the October issue of The Plant Cell. Jaewook Kim, Kijong Song, and Eunae Park, featured authors of Epidermal Phytochrome B Inhibits Hypocotyl Negative Gravitropism Non-Cell Autonomously Jaewook Kim Current Position: Graduate student, […]

EDITORIAL: The Plant Cell Begins Opt-in Publishing of Peer Review Reports

As of January 2017, The Plant Cell will offer authors the option of associating a Peer Review Report with each research article. Reviewer anonymity will be strictly maintained. The reports will include the major comments from reviewers and the editors’ decision letters along with the authors’ response to reviewers for each submission of the manuscript […]

RNA Degradome Studies Give Insights into Ribosome Dynamics

IN BRIEF by Gregory Bertoni gbertoni@aspb.org RNA metabolism is key to a number of crucial processes in the cell, including transcription, RNA splicing, translation, and gene regulation. For efficient translation, mature mRNAs must have a 7-methylguanosine cap on the 5′ end to help recruit the translation machinery and protect the mRNA from exonucleases. If the […]

Recognizing featured Plant Cell first authors, October 2016

Recently, we’ve been profiling first authors of Plant Cell papers that are selected for In Brief summaries. Here are the first-author profiles from the October issue of The Plant Cell. Olivia Wilkins and Christoph Hafemeister, featured first authors of EGRINs (Environmental Gene Regulatory Influence Networks) in Rice That Function in the Response to Water Deficit, […]

Congratulations to Yoshinori Ohsumi

Warmest congratulations to Yoshinori Ohsumi, 2016 Nobel Laureate in Physiology or Medicine, “for his discoveries of mechanisms for autophagy”.  Autophagy (self-eating) is a process through which cells selectively degrade and recycle cellular components. Ohsumi’s research has primarily focused on yeast, but he has also studied autophagy in plants. In fact, for the past twenty years  […]
