Small RNAs are key regulators involved in plant growth and development. Two groups of small RNAs are abundant during development of pollen in the anthers—a critical process for reproductive success. A research collaboration has demonstrated the function of a genetic pathway for anther development, with this pathway proven in 2019 work to be present widely in the flowering plants that evolved over 200 million years ago. The research team was led by Blake Meyers, Ph.D., member, Donald Danforth Plant Science Center and professor, Division of Plant Sciences, University of Missouri, and Virginia Walbot, Ph.D., Professor of Biology, Stanford University. Their findings, “Dicer-like 5deficiency confers temperature-sensitive male sterility in maize” were published in the journal, Nature Communications.
