Haplotype variation and KASP markers for SiPSY1 – A key gene controlling yellow kernel pigmentation in foxtail millet
Carotenoid biosynthesis and accumulation are important in determining nutritional and commercial value of crop products. Yellow pigmentation of mature kernels caused by carotenoids is considered a vital quality trait in foxtail millet, an ancient and widely cultivated cereal crop across the world. Genomic regions associated with yellow pigment content (YPC), lutein and zeaxanthin in foxtail millet grains were identified by genome-wide association analysis (GWAS), and SiPSY1 (Phytoene synthase 1 which regulates formation of the 40-carbon backbone of carotenoids) was confirmed as the main contributor to all three components by knockout and overexpression analysis. SiPSY1 was expressed in seedlings, leaves, panicles, and mature seeds, and was subcellularly localized to chloroplasts. Transcription of SiPSY1 in 15 DAP immature grains was responsible for YPC in mature seeds. Selection of SiPSY1 combined with increased YPC in mature grains during domestication of foxtail millet was confirmed. Haplotype analysis suggested that expression level of SiPSY1 could be a selection target for future breeding programs, and a KASP marker was developed for selection of favorable SiPSY1 alleles in breeding. The results of this work will benefit nutritional and commercial improvement of foxtail millet varieties, as well as other cereal crops.

期刊介绍:
The major aims of The Crop Journal are to report recent progresses in crop sciences including crop genetics, breeding, agronomy, crop physiology, germplasm resources, grain chemistry, grain storage and processing, crop management practices, crop biotechnology, and biomathematics.
The regular columns of the journal are Original Research Articles, Reviews, and Research Notes. The strict peer-review procedure will guarantee the academic level and raise the reputation of the journal. The readership of the journal is for crop science researchers, students of agricultural colleges and universities, and persons with similar academic levels.
