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

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 chlorophyll degradation, including its regulatory mechanisms. For example, […]

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.

The Power of Plasticity in Polyploid Persimmon

IN BRIEF by Jennifer Lockhart [email protected] Most plants are hermaphrodites, producing perfect flowers with both male and female functions. In roughly 6% of plants, however, male (usually XY) plants produce only male flowers and female (XX) plants produce only female flowers. These dioecious plants cannot self-pollinate, ensuring genetic diversity and facilitating the breeding process. In […]

Best of 2016: Top Topics in Plant Physiology jounal

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 Physiology this year was “Mechanosensitivity below ground: touch-sensitive smell-producing roots […]

Transcriptional repression of K+ uptake by ARF2

HAK5 is a high-affinity potassium transporter that is transcriptionally repressed in high K+ conditions. Zhao et al. identified hormone-related cis-elements in the HAK5 promoter. They screened mutants deficient in transcription factors associated with these cis-elements and found that arf2 mutants show enhanced K+ uptake and root growth on low-K medium, whereas ARF2 overexpression lines showed […]

Evolutionary origins of stomata ($)

Questions remain about the evolutionary origins and functions of stomata. They are absent from liverworts, present to a limited extent in mosses, and are found on 410 million year-old fossils of Cooksonia, a leafless plant. Chater et al. show that orthologs of two key transcription factors that control guard cell development in Arabidopsis are expressed […]

Improving Rubisco

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 greater Rubisco efficiency. Sharwood et al. examine the kinetic properties of Rubisco enzymes […]
