Reproductive development of common buckwheat ( Moench) and its wild relatives provides insights into their evolutionary biology.

Introduction: Understanding the complex inflorescence architecture and developmental morphology of common buckwheat () is crucial for crop yield. However, most published descriptions of early flower and inflorescence development in Polygonaceae are based on light microscopy and often documented by line drawings. In and many other Polygonaceae, an important inflorescence module is the thyrse, in which the primary axis never terminates in a flower and lateral cymes (monochasia) produce successively developing flowers of several orders.
