I have a soft-spot for plant biology. In my final year at university, having exhausted all of the bacteria-related biochemistry lectures, I took a bacteria-related lecture course with the plants department. It was a smaller department, and seemed a lot friendlier and nicer. Also the biscuits in the tea-room were cheaper.
So I do like to write about plants every now and again, and it isn’t a very difficult task because like every other multicellular organism on the planet, plants also suffer from bacterial infections. Unlike humans, they don’t have a blood stream to carry immune cells around, so they instead rely on bombarding bacteria with nasty chemicals, quickly killing off any parts of the plant that get infected and acquiring a kind of plant resistance to stop attacks occurring again. (The three links are to a mini-series on plant immunology on my old blog.)
