Doctoral thesis in botany rewarded with SEK 130 000

Frida Rosengren, librarian at the Department of Biology, receives Bengt Jönssons prize in botany. She receives 130 000 Swedish crowns. It is the Royal Physiographic Society of Lund that every fifth year rewards the most deserving doctoral thesis in botany.

Frida Rosengren receives the prize for her doctoral thesis from 2015 titled Genetic variation and sexual reproduction in a moss with dwarf males, Homalothecium lutescens.

”I am very grateful. I really feel appreciated, it’s great! When I first got the email I actually thought it was spam, but fortunately that was not the case.”

Dwarf males exist among different groups of animals but is far less common on plants, with the exception of moss. On moss male spores land and germinate on female sprouts. The result is dwarf males just a few millimetres in size. When dwarf males grow on larger females it favours fertilization.

In her doctoral thesis Frida Rosengren studied the moss Homalothecium lutescens. She studied the geographical distribution and the existence of dwarf males. She performed genetic studies to investigate the affinity and to find out how they spread and why the dwarf males exist at one place but not in another.

”It was very exciting when I took male spores from another species and put it on my species and discovered it started to grow. Dwarf males of one species can grow on another species and that had not been proven by researchers until I did it”, she says.

Despite her reward of 130 000 Swedish crowns Frida Rosengren has decided not to continue doing research. Instead she is a librarian at the Department of Biology in Lund, a job where her competence in botany is very useful.

She has not yet decided how to spend the money, but some of it will probably go towards a trip.

”There is one thing though that I definitely will buy and that is a luxury battery for my electric bike. The battery I have does not last to Malmö and back again.”
