The science of plants and more


Quick plants

Quick plants One, two, gotcha, that one is not going anywhere. Who wants to catch flies needs to be super quick, like Venus flytrap. A real hunter, this plant. Where most plants are preyed by hungry insects, is this meat-eater eating them. This makes Venus flytrap already an exception within plants. Another difference, most plantsContinue reading “Quick plants”

Regulating enzymes

Regulating enzymes Regulation can happen in many ways. For metabolic pathways three main regulatory mechanisms can be distinguished. A) The production of its enzymes, B) the degradation of these enzymes and C) regulating the activity of these enzymes. Where the regulation through the production and degradation of enzymes is crude and imprecise, regulation through regulatingContinue reading “Regulating enzymes”

The art of bending

The art of bending How to bend, or more precisely, how do plants bend? This was the question Baral and his colleagues set to answer. The bending of plants occurs as a result of many stimuli, such as wind, the search of nutrients, or obstacles. These can all occur at various stages of plant development.Continue reading “The art of bending”

Pollinated by roaches

Pollinated by roaches Thinking about the pollination of flowers most of us generally assume bees do all the hard work. While bees are busy as bees pollinating flowers, they are hardly the only ones recruited for the job. Loads of other insects are helping out, with bats and hummingbirds also part of the pollination workforce. AContinue reading “Pollinated by roaches”

PLC sandwich

PLC sandwich Another genius bit of biological design comes from the enzyme PLC. PLC is a phospholipase whose job it is to cleave of the headgroup of PI(4,5)P2, a membrane lipid. Like tethering proteins, PLCs are made up out of a couple of domains. At its core there are three domains. There is the catalyticContinue reading “PLC sandwich”

Tethered to science

Tethered to science For a long while I haven’t posted anything, being too tired and work got in the way. Then after combing back from a conference and a break late February, full of ideas but no energy to work them out, I turned to my GP.  There I was told I was overworked, warnedContinue reading “Tethered to science”

Plasticity in phloem development

Plasticity in phloem development Last week at a symposium, we were reminded by Antia Rodriguez-Villalon that in plants organogenesis does not stop after germination. In fact, plants keep producing new organs through their lives. While most of us think by organ formation in plants first about leaves or flowers, Antia Rodriguez-Villalon work actually focusses onContinue reading “Plasticity in phloem development”

Leaf shape development

Leaf shape development On of the things that intrigues me most in biology is the development of organisms. How does that single cell that is just fertilised knows what to do. To get its polarity established, initiate cell division at the right time, place and direction. What makes it go on developing into recognisable plantContinue reading “Leaf shape development”

Giving a talk

Giving a talk When preparing to give a talk about your work you always need to make lots of decisions. One is about the amount of background vs results. Ideally you would like to have lots of time to discuss your new results, but for the audience to place them into context, or to understandContinue reading “Giving a talk”

What makes a binding domain

What makes a binding domain One of the projects that I am busy with at the moment is writing a review about phosphoinositide binding domains. Preparing for that I have been reading old reviews on the same topic. One thing that I noticed was that some domains which have shown to bind phosphoinositides, like theContinue reading “What makes a binding domain”

Context is everything

Context is everything I have been reading a ton of articles lately, in order to get a better grip on phosphoinositide-binding proteins. Slowly, this made me realise that how we present our findings is important. Of course a well written article is easier to read than one that is not. But the order we presentContinue reading “Context is everything”

How plants avoid salt

How plants avoid salt Plants don’t like high salt levels in their cells. They do therefore everything they can to avoid this. As mentioned in earlier posts plants have a number of strategies for this. However, the best strategy is not taking up to much salt in the first place. Being sensitive to salts, plantsContinue reading “How plants avoid salt”

Work in progress

Work in progress This last week I have been busy with organising my results and preparing them for a presentation that I gave for some of our department. And although I have made some progress with my project since I started it, the presentation I gave highlighted the lack of useful progress during the lastContinue reading “Work in progress”
