Installation of C4 photosynthesis into C3 crops appears a realistic way to boost crop yields.  A key aspect of C4 photosynthesis is an enlarged bundle sheath volume and an increase in bundle sheath chloroplast number.  To identify the regulators of this phenotype, Döring et al. subjected Arabidopsis…

The establishment of root nodule symbiosis in legume roots involves the perception, infection, and accommodation of nitrogen-fixing rhizobia. The de novo formation of root nodules relies on complex developmental programs coordinated through different tissues via unknown cellular routes. Gaudioso-Pedraza…

Properly functioning guard cells change size in response to myriad stimuli to control the passage of water and gasses through stomata. The change in volume is mirrored by changes in plasma membrane surface area, with membrane moving dynamically between tonoplast and plasma membrane as needed. Bourdais…

Assessing the effect of rising CO2 concentrations on plant growth and physiology traits is crucial in order to determine how ecosystems and crop production systems will perform in future climates.  Such assessments have been made with free-air CO2 enrichment (FACE) experiments, which have provided a…

Increases in atmospheric CO2 have been shown to confer enhanced photosynthetic rates, boosting plant growth and yield.  Unfortunately, there is evidence that the content of minerals important for human health are reduced in both the foliar and edible tissues when plants are grown under elevated CO2…

Strigalactones are phytohormones that regulate plant growth and development processes. The α/β hydrolase D14 (metabolizes strigolactone) interacts with the F-box protein D3 to ubiquitinate and degrade the transcription repressor D53. This process inhibits shoot branching. However, it is still unknown…

Opinion: Limits to tree growth and longevity ($) I think trees are awesome, and I mean that in the truest sense of the word. They dwarf us in height, and when we look at a tree that has lived for hundreds or thousands of years it is impossible not to think of that span in terms of human generations…

Prioritization and Work / Life Balance: Do Less, Work Better Recorded November 2018  About This Webinar Work/life balance is important to our society regardless of gender. Many professionals today are experiencing the “sandwich” effect—taking care of a family as well as aging parents. In…
