Research team discovers new kind of signalling mechanism in plant cells
Date:6/25/2013

/b>

"Why the plant recognises methionine and similar amino acids at all is still absolutely unclear", the Bochum biochemist goes on. "One possibility is that it reacts in this way to nutrient sources in the environment that contain amino acids. However, it is also possible that the plant deliberately produces amino acids itself to send signals similar to the way it happens in the human brain."

Receptors expressed in frog egg cells for analysis

For the analyses, the RUB team isolated the glutamate-like receptor from plant cells and implemented it in a cell that has no similar receptors an unfertilised frog egg cell. "It is almost impossible to examine the receptor directly in the plant", Hollmann explains. "There are so many processes operating at the same time that it is extremely difficult to filter out the critical signals."
