Rubisco (ribulose 1,5-bisphosphate carboxylase/oxygenase) is one of a kind, simultaneously recognized as one of the most abundant and important enzymes, and also widely characterized as flawed because it uses both O2 and CO2 as substrates, leading to both carboxylation and oxygenation of ribulose bisphosphate. When CO2 is used as a substrate, the carbon is fixed […]
Plants synthesize interesting chemicals that attract, deter, amuse, and harm their predators. Some of the most harmful to humans have been selectively eliminated through the process of domestication, but others render potential food sources inedible. This review by Liu et al. discusses four approaches to increasing harvest index (product per plant) by selectively removing phytotoxins […]
As an educator, I reply on metaphors and stories to engage my readers, yet the line between hyperbole and engagement is thin. The concept of plant-plant communication is exciting, and certainly has some truth, but unfortunately has spilled over into a narrative that perhaps is more fiction than fact. In particular, the notion that the […]
Self-burying seeds are high on the list of “aren’t plants amazing”. Seeds of several species carry appendages that change shape when exposed to moisture and that are oriented in such a way so that their shape changes push the seed underground (don’t take our word for it – see https://youtu.be/TOJG5mF6OLs). Burrowing underground gives the seed […]
Review: Photorespiration is the solution, not the problem Rubisco (ribulose 1,5-bisphosphate carboxylase/oxygenase) is one of a kind, simultaneously recognized as one of the most abundant and important enzymes, and also widely characterized as flawed because it uses both O2 and CO2 as substrates, leading to both carboxylation and oxygenation of ribulose bisphosphate. When CO2 is […]
Plant Cell Webinar: Crop Breeding for Climate Resilience Celebrating the January 2023 Focus Issue on Climate Change and Plant Abiotic Stress Recorded Wednesday, February 22, 2023 About This Webinar In many regions of the world, climate change is leading to increased exposure to abiotic stresses for plants as well as humans and other animals. The most obvious […]
Microalgae are small, photosynthetic algae that have emerged as important contributors to food and nutrient production. This review describes the many ways they can be grown (e.g., autotrophic, with sunlight or artificial light; heterotrophic, with sugar inputs; or mixotrophic, a combination of both) and the many things they can produce. Interestingly, the mixotrophic method can […]
Review: Hypes, hopes, and the way forward for microalgal biotechnology Microalgae are small, photosynthetic algae that have emerged as important contributors to food and nutrient production. This review describes the many ways they can be grown (e.g., autotrophic, with sunlight or artificial light; heterotrophic, with sugar inputs; or mixotrophic, a combination of both) and the […]
This is a fantastic article to help new, future, and even current lab heads think about their postures, priorities, and practices. It was developed through a workshop held during the Arabidopsis meeting, originally scheduled for 2020 but held online in 2021 and run by several scientists who recently became principal investigators. The first part provides […]
