Rice (Oryza sativa L.) is a major cereal crop, providing food for billions of people globally. Unlike other cereals, rice is rich in pigmented landrace varieties. Red, brick-red brown, and purple rice originated in the upland and lowland areas of Yunan, China, Northern Thailand, and Myanmar. Interestingly, the ancestors of cultivated rice, Oryza rufipogon, and O.nivara, had pigmented grains. The neo-domestication of cultivated pigmented rice is perplexing and needs further investigation utilizing recent advancements in Pangenomics and Epigenomics in rice.
Flavonoids, anthocyanin, pro-anthocyanin, and carotenoids are responsible for the spectrum of coloration in various plant organs, including leaf, auricle, glume, embryo, and grains. This Research Topic aims to explore the interaction between environmental stresses, particularly heat and cold, and flavonoid contents, which can lead to a more stabilized expression and nutritional profile in both leaf and grain. Recently, the discovery of leaf chlorophyll and flavonoid pigment mutants has substantially impacted the interplay between leaf coloration, photosynthetic efficiency, and nutritional properties.
We welcome articles on the following, but not limited to, topics:
- The current status of Pan-genomics of genetic variation among wild ancestors, local landraces,0-pl., and cultivated pigmented rice varieties found in the upland, terrace, and lowland rice cultivation systems.
- Current understandings of Neo-domestication of local landraces leading to improved pigmented rice varieties cultivated globally.
- Research on hidden epigenomes, transcriptomes, metabolomes, and phenomes regulating the expression, accumulation, and stability of various pigments, including flavonoids, chlorophyll, and carotenoids, in different plant organs, concerning nutrient composition, particularly on leaves and grains.
Keywords:
pigmented rice, plant genomics, cereal crops, pangenomics, epigenomics, flavonoids, carotenoids, photosynthetic efficiency
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
