Plants therefore have developed complex signalling pathways that optimize the opening width of stomata to match the environmental conditions. In response to changes in the availability of light, carbon dioxide and water, they can open or close these pores. How did the signalling pathways that are responsible for this regulation evolve? This is being investigated at Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, in the team of the plant scientist Rainer Hedrich.
"We are currently collecting and analyzing data from different plant species," says Professor Hedrich. He explains that this research also has relevance for agriculture: "Knowledge about the evolution of these signalling pathways could feed into breeding efforts to develop crops that can grow with less water." After all, the majority of the drinking water supplied to plants via irrigation systems is lost through stomatal pores. In view of climate change, plant varieties that can cope well with drought are highly sought-after.

In the journal Trends in Plant Science, JMU researchers Dr. Frances Sussmilch, Professor Jörg Schultz, Professor Hedrich, and Dr. Rob Roelfsema now summarize the current state of knowledge on the signalling pathways that plants use to regulate their water balance.
The Würzburg team has reconstructed the evolutionary history of important genes that control the movement of leaf pores in flowering plants. It turned out that most of these genes belong to old gene families that occur in...
