Review: Transport and homeostasis of K & P ($)

/
Nitrogen (N), phosphorus (P), and potassium (K) are the three macronutrients required in highest amounts for plant growth. N is abundant in the atmosphere, therefore plentiful if we overlook the energetic costs of converting N2 to usable form. By contrast, K and P are present in limited amounts in the…

Review: Nitrogen sensing in legumes ($)

/
As a consequence of their ability to fix nitrogen in symbiosis with bacteria, legumes make key contributions to ecosystems and provide protein-rich foods for humans and other animals. Recent years have uncovered the nature of the signals involved in the cross-kingdom dialogues that occur between plant…

Plant-permeable trehalose 6-phosphate analogues increase yield and resilience ($)

/
Trehalose-6-phosphate (T6P) is a sugar signaling molecule that regulates how plants allocate and use sucrose, which in turn affects stress resilience and yields. Griffiths et al. designed a plant-permeable, photo-activated T6P analogue that is converted to T6P in planta. Spraying this compound onto plants…

Metabolic control of tobacco pollination ($)

/
A germinated pollen grain extends a pollen tube through the stigma and style of the flower to deliver two sperm cells to an ovule.  Tip-directed growth of the pollen tube requires a large energy input, but how does the pollen tube obtain energy while growing through the flower tissues?  Goetz et al.…

A dephytylase involved in chlorophyll turnover

/
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…

It was a Great, Green Year: Identification of a Chlorophyll Dephytylase That Functions in Chlorophyll Turnover

/
IN BRIEF by Jennifer Mach jmach@aspb.org 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…

Best of 2016: Top Topics in The Plant Cell journal

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…

Biofortification of plants: New Reviews ($)

/
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…
