Chlorophyll has an aliphatic phytol side chain that anchors it to light-harvesting complexes. During senescence, chlorophyll is degraded first by the enzymatic removal of Mg to produce pheophytin, which is dephytlated by pheophytinase. Through the identification of a mutant allele with elevated enzymatic…

IN BRIEF by Jennifer Mach [email protected] Green may have been the Pantone Color of the Year for 2013 (http://www.pantone.com/color-of-the-year-2013), but 2016 was a great year for papers on chlorophyll research, at The Plant Cell and beyond. In this year, we saw a pile of interesting papers examining…

We’ve highlighted some of the Plant Cell papers that were widely shared, liked, blogged, retweeted and otherwise garnered high-levels of attention this year. Perhaps you can use some holiday-season quiet time to catch up on those you missed. Reviews and Perspectives Creating order from chaos: epigenome…

We’ve highlighted some of the Plant Physiology papers that were widely shared, liked, blogged, retweeted and otherwise garnered high-levels of attention this year. Perhaps you can use some of that holiday-season quiet time to catch up on those you missed. The breakaway attention-getter from Plant…

Rubisco (Ribulose-1,5-bisphosphate carboxylase / oxygenase) is the enzyme responsible for fixing almost all inorganic carbon into organic form, but it is not optimized for current conditions. As temperature and CO2 levels increase, there is an opportunity to increase photosynthetic efficiency by engineering…

Gibberellin hormones were famously identified as the product of Gibberella fujikuroi, a fungal pathogen that stimulates host cell elongation, and then subsequently recognized as a hormone produced by plants as well. Fungi and plants produce gibberellins from distinct biochemical pathways, in an example…

Earth colonization by life happened billions of years ago. Weathering of soils by microbial mats leave a characteristic signal that can be used to shed light on the mechanisms involved in colonization. In this review, Lenton and Daines discuss the growing mass of evidence that points to the biogeochemical…

Biofortification is the nutritional enhancement (using conventional or genetic engineering approaches) of food with vitamins or micronutrients with the goal of improving the human diet. A set of new reviews in Current Opinion in Biotechnology summarizes progress towards biofortification of plants to…
