Abstract

Domestication represents a unique opportunity to study the evolutionary process. The key step in the evolution under domestication of cereal crops is the elimination of seed dispersal traits. Here we show that ObSH3, a YABBY transcript factor, is required for the development of the seed abscission layer and that selecting a genomic segment deletion containing SH3 resulted in the loss of seed dispersal in populations of African cultivated rice (Oryza glaberrima Steud.). Functional characterization of SH3 and SH4 (another gene controls seed shattering on chromosome 4) together revealed that multiple genes can lead to a spectrum of non-shattering phenotypes, affecting other traits such as ease of threshing that may be important to tune across different agroecologies and postharvest practices. The molecular evolution analysis of SH3 and SH4 in a panel of 93 landraces provide unforeseen geographic detail of African rice domestication history, tracing multiple dispersals from a core heartland and introgression from local wild rice. Identification of ObSH3 provides new insights into a critical crop domestication process and also sheds light on the molecular mechanism underlying abscission layer development.
