Integration of multi-omics data and phenotyping provides insights into purple leaf sheaths color in millet seedling stage.

ABSTRACT:

Background

The millet, an important coarse grain crop, exhibits drought resistance, water conservation efficiency, and adaptability to poor soil conditions. Although the purple leaf sheath is a prevalent phenotype, the underlying mechanisms of color variation remain unclear. Previous studies suggested that leaf sheath coloration might result from differential accumulation of plant pigments, yet the key substances and molecular mechanisms governing color formation in millet have not been systematically elucidated.

Results

We investigated the metabolic pathway underlying millet leaf sheath coloration using multi-omics analysis. Physiological data revealed that the purple phenotype was associated with up-regulated anthocyanin biosynthesis and down-regulated chlorophyll accumula
