A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts -- land plants so old they don't even have proper roots. The discovery highlights the fundamental evolutionary dynamic of co-opting, evolving a mechanism first and adopting it for a different purpose later.

A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts -- land plants so old they don't even have proper roots. The Kobe University discovery highlights the fundamental evolutionary dynamic of co-opting, evolving a mechanism first and adopting it for a different purpose later. When scientists discover that a gene is necessary for the development of a trait, they are quick to ask since when this gene has been involved in this and how the evolution of the gene has contributed to the evolution of the trait. Kobe University plant biologist FUKAKI Hidehiro says:"My group previously discovered that a gene calledbelongs to is involved in plant organ development. So we wanted to know whether the equivalent of this gene in other plants is also involved in similar processes.". This plant doesn't even have roots that can extract water or nutrients from the soil, but it has its own version of thegene produces a protein that belongs to the vast group of heme-binding proteins and that means that it may bind a molecule called"heme," which is involved in energy transfer within the cell. Fukaki says,"Given that heme-binding proteins were not known to be involved in organ development in plants, another significant point in our study is that we showed that the RLF protein actually has a heme, both in the liverwort and inThe Kobe University researcher expects that learning more about how the RLF protein interacts with others will clarify more about the evolution of plant organ development. Fukaki adds,"The fact thatplays an important role in organ development since at least the dawn of land plants is an example of how evolution often co-opts existing mechanisms for new functions, such as for root development, which evolved only after liverworts and mosses branched off the other land plants." This research was funded by the Ministry of Education, Culture, Sports, Science, and Technology Japan , the Japan Society for the Promotion of Science , the Japan Agency for Medical Research and Development , and the Japan Science and Technology Agency . It was conducted in collaboration with researchers from the University of Tokyo, Nara Women's University, Ritsumeikan University, and Osaka University. Kentaro P.
