IN BRIEF by Jennifer Mach [email protected] Plants can dispose of organs such as leaves and recycle the nutrients in these organs into new leaves, seeds, or storage organs. However, when separated from its photosystem proteins, chlorophyll can be phototoxic, absorbing light and producing high-energy electrons. The complex chlorophyll degradation pathway solves this problem by breaking […]
IN BRIEF by Jennifer Lockhart [email protected] Heat and drought stress greatly restrict crop productivity, but most of what we know about a plant’s response to these stresses comes from controlled laboratory studies. This factor, along with the complex nature of these responses, has hampered efforts to breed and engineer crops with improved stress tolerance. Plants […]
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 September issue of The Plant Cell.

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 August issue of The Plant Cell. Aman Y. Husbands and Vasudha Aggarwal, featured first authors of In Planta Single-Molecule Pull-down (SiMPull) Reveals Tetrameric Stoichiometry of HD-ZIPIII:LITTLE ZIPPER Complexes. Aman Y. Husbands […]
IN BRIEF by Jennifer Lockhart [email protected] At first glance, starch is just an inert, calorie-laden material produced by plants to store excess carbohydrates derived from photosynthesis. Starch accumulates in leaf mesophyll cells during the day and is metabolized at night. The precise circadian control of this process ensures optimal energy utilization. Starch also accumulates in […]
IN BRIEF by Jennifer Mach [email protected] Assessing protein-protein interactions remains a fundamental challenge for plant biologists. Current methods such as coimmunoprecipitation (co-IP), yeast two-hybrid, bimolecular fluorescence complementation (BiFC), and others can produce artifacts and also yield only a bulk “ensemble” readout that is difficult to quantify, much less examine statistically. For example, the fluorescent protein […]
Carotenoids are nutritionally important phytonutrients. Comas et al. describe a strategy to enhance the production of cartotenoids in the seed endosperm. They start with quantitative metabolomics and gene expression data which they feed into mathematical models to determine which gene(s) need to be engineered. Some of the genes they identify have been identified and verified […]
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 July issue of The Plant Cell. Fangwei Gu, featured first author of Arabidopsis CSLD5 functions in cell plate formation in a cell cycle-dependent manner Current Position: Communication Specialist at WuXi AppTec. […]
IN BRIEF by Kathleen L. Farquharson [email protected] Polysaccharide-rich cell walls are a distinguishing feature of plants that influence many aspects of growth and development, including cell division. Whereas contractile rings pinch dividing cells into two daughter cells in other eukaryotes, newly built cell walls partition the products of plant cell division. The phragmoplast guides construction […]
