Nitrogen-fixing cyanobacteria such as Anabaena sp. PCC 7120 have the challenge of supporting nitrogenase, an enzyme that is highly sensitive to oxygen, and simultaneously photosynthesis, an oxygen-producing set of reactions. They accomplish this by segregating these reactions into two cells, heterocysts and vegetative cells. Malatinszky et al. curate and compile a stoichiometric model of the […]
The yield of a maize plant is correlated with the size, shape and number of kernels it produces. Miller et al. have developed an automated system to quantify these crucial attributes from photographs of kernels both on and off the cob. Their methods will enable researchers and breeders to record maize traits with greater precision […]
In an interesting and accessible review, Peyraud et al. provide a big-picture view of how systems biology can be used to address plant-pathogen interactions. They describe the core interactions scaling from molecular to ecosystem / environment, and describe the different types of models that can be used to assess and predict the outcomes, as well […]
Programmed cell death (PCD) is an active process that occurs as part of normal development and also contributes to defense against pathogens. While there are many similarities in developmental PCD (dPCD) and pathogen-triggered PCD (pPCD), there are also differences. Huysmans et al. review and contrast these two types of PCD. A key conclusion is that […]
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
IN BRIEF by Kathleen L. Farquharson [email protected] 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 […]
IN BRIEF by Nancy R. Hofmann [email protected] 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, […]
Frédéric Bouché, a postdoctoral research with Richard Amasino at the University of Wisconsin, recently caught our attention when he published a set of impressive visual abstracts to support his latest research papers. We invited him to share how and why he makes these images. -Editors When you work hard, and your scientific work is finally […]
