Plant Biology is the name of the annual meeting organized by The American Society of Plant Biologists- ASPB (& sometimes co-organized with partner plant science societies from around the world). This is one gathering of the plant science community, one of the bigger ones that occurs each year involving over 1,000 plant scientists over 5 … More What is Plant Biology? (#plantbiology15)
As you add condiments to your burgers, hot dogs, etc. at a summer barbecue, take a minute to reflect on where they come from. Most are plant products. And a recent study published in PNAS tells the story about how humans wound up with mustard. As life got going, it started to fill new niches … More Cutting the Evolutionary Mustard.
Being multi-cellular has advantages. Specialization of cells for different jobs is one advantage– akin to humans adopting agriculture, freeing up some of us to do other things. Multi-cellularity is also quite challenging as those cells have to communicate well together and there are more cells to feed/keep healthy. Different cells have to be able to … More Guardians of Gas Exchange.
Flowering Flowering is a killer application of the natural world. There are 300,000 extant species of flowering plants, dwarfing any other type of plant. There are only several thousand species of other types of plants (about 15,000 mosses exist today– the next most abundant group of plants). To say flowers are an evolutionary success story … More Flowering time and genetic memory.
Do you ever wonder about how a plant goes from seed to whole plant? The flip answer is ‘it grows’. But how? How is a plant organized to generate shoots, leaves, roots, flowers, etc.? A scientist that studied that question passed away recently. His name: Ian Sussex. One of his former postdocs and a great … More Ian Sussex and Plant Meristems
For the last 3 years, Fascination of Plants Day has been observed to take note of plants in our world and to really become aware of these organisms that are right in front of us and yet go unnoticed so often. Plants are ubiquitous to the point that they’re a medium we exist in. Even in … More Fascination of Plants
This week, I’m going to write about a Genetically modified crop plant brought into the world by nature. Did you think only humans could genetically modify organisms? Nature’s been at it since long before humans were around. An international team of researchers published a paper in PNAS about the discovery of two T-DNA loci in … More A Naturally Genetically Modified Organism.
Say you write something and submit it for editing. Your editor sends it back with comments. And you create a new version and re-submit and so on. it’s a feedback loop. With editor/writer, it’s a loop of iterative improvement resulting in something publishable (ideally). Feedback loops in biology are also quite common. A recent paper … More Small surprises and a new feedback loop.
What to make of Junk DNA A few weeks ago, science writer Carl Zimmer wrote (and literally bled in T. Ryan Gregory’s lab) a column in the New York Times exploring “junk” DNA. It’s a really good piece that also hits on how scientists have been arguing for a long time about what’s adaptive, what’s random, … More A small plant genome and “junk” DNA.
Einstein’s theories of relativity enables out modern global positioning system (GPS) to work because the satellites have to correct for the distances between the satellites and Earth. This was not the intent when Einstein derived the mathematics of the relativistic universe. At least I don’t think it was. He was playing around with figuring out how … More From nature to product.
