Phenological and morphological variation are widely viewed as a pivotal driver of ecological adaptation and speciation. Here, we investigate variation patterns of flowering phenology and morphological traits within and between O. rufipogon and O.

- - The study investigates ecological speciation using two wild rice species, Oryza rufipogon and Oryza nivara, focusing on how habitat differences contribute to their phenotypic divergence and genetic structure.
- - Researchers created a detailed genetic map and identified 113 quantitative trait loci (QTLs) linked to 16 traits, with a mix of major and minor gene effects contributing to the observed differences.
- - Results suggest that natural selection drives rapid diversification by influencing multiple traits simultaneously, which could inform better breeding strategies for rice.
Article Synopsis
- - The origin of domesticated Asian rice has been debated for over 50 years, focusing on whether it was domesticated once in China or multiple times in different locations.
- - Researchers analyzed 1,578 genomes and discovered 993 selected genes, indicating that japonica and indica rice types are closely related and likely share a single domestication origin.
- - Most domestication alleles (around 80%) came from wild rice in China, while about 20% originated from wild rice in South and Southeast Asia, supporting the idea of separate domestication events.
