Review: Transport and homeostasis of K & P ($)
Plant Science Research Weekly, Research0 Comments
/
Nitrogen (N), phosphorus (P), and potassium (K) are the three macronutrients required in highest amounts for plant growth. N is abundant in the atmosphere, therefore plentiful if we overlook the energetic costs of converting N2 to usable form. By contrast, K and P are present in limited amounts in the…
Plant-permeable trehalose 6-phosphate analogues increase yield and resilience ($)
Plant Science Research Weekly, ResearchTrehalose-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…
Photosynthetic machinery protection induced by UV-B in Chlamydomonas
Plant Science Research Weekly, ResearchLight is good, too much light is bad. Photosynthetic organisms can dissipate excess light through a variety of means including non-photochemical quenching. Czechowski et al. show that in Chlamydomonas perception of UV-B light via the nuclear/cytosolic receptor UVR8 induces accumulation of proteins that…
Metabolic control of tobacco pollination ($)
Plant Science Research Weekly, Research, Research BlogA 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
Plant Science Research Weekly, ResearchChlorophyll 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
Research, The Plant Cell, The Plant Cell: In BriefIN 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…

Improving Rubisco
Plant Science Research Weekly, ResearchRubisco (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…
