Nice to read about a new breakthrough in botany. The field doesn't get much attention at all. Maybe now it will benefit from the popularity of Martian, the movie.
That's because they are expensive to maintain, professorships have been faded out and biology students and post-grads are usually not so much interested in real plants and systematics anymore, but more in genetics and laboratory work.
The small state of Saarland doesn't have a single publically accessible botanical garden anymore. Across Germany the outlook is dim.
