Flowering plants are divided into two major groups (the monocots and dicots) which split apart 150 million years ago. Schoonbeek et al. show that a receptor can be moved from Arabidopsis thaliana (a dicot) into rice (a monocot), and this can make the rice more resistant to disease.
Not all microbes are bad. Recently the importance of the microbes in the guts of humans is becoming clear, but it’s not just animals that benefit from the microbes inside of them- so do plants, and these microbes could have potential in farming.
Humans have been growing crops for 10,000 years and in this time we’ve selectively bred for crops which are easier to harvest. In doing this important genes involved in plant defence could have been lost along the way. Palmgren et al. look into the potential for re-introducing old genes into modern crops.
For my project I am looking into whether a product based on vanilla can elicit defence responses in plants. I covered why there’s research into natural products in my last post.

Chemical fungicides are currently under threat from new legislation. Loss of fungicides could lead to yield losses in crops due to lack of disease control. Alternative methods in to crop protection currently include the use of natural products which are less likely to damage the environment and be more acceptable by the public.

It’s well known that animals can fight pathogens using immune cells and antibodies which travel around the body in the blood. Plants lack these mobile immune cells and they don’t produce antibodies. So, how do plants defend themselves against pathogens?
