This week's papers were seleted by Renee Dale. Renee is a PhD student in biology and an MS student in statistics at Loiusiana State University who is studying mathematical biology and biostatistics for plant biology applications. She is also working on an educational video game! Renee selected these…

Metabolites. Terpenes are derived from isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), which are produced in two separate pathways: in the cytosol (via mevalonate, MVA) and the plastid (via methyl-D-erythritol-4-phosphate, MEP). The products of terpene metabolism include numerous…

Over the last two decades, Ash dieback (ADB) has been sweeping through Europe killing or damaging a large proportion of European common ash trees (Fraxinus excelsior).  ADB results from infection by wind borne spores of the fungus Hymenoscyphus fraxineus.  As ADB spread and the scientific 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…

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…

All gases in the N cycle, including nitric oxide (NO), are present in oceans, either because of gas exchanges at the air-water interface or because they are produced within oceans themselves. NO, a physiologically important gaseous transmitter, is generated in seawater by nonbiological photochemical…

Of the many classes of natural products produced by plants, terpenoids are the most structurally diverse, with well over 25,000 established compounds. In maize (Zea mays), terpene olefins are nearly ubiquitous components of induced volatile emissions following biotic stress. In contrast to our understanding…

Lignified cell walls constitute an important renewable and sustainable feedstock for the production of fermentable sugars, biochemicals, and biomaterials.  In biorefineries, plant cell wall polysaccharides are depolymerized into simple monomeric sugars, a process called saccharification. These sugars…
