Abstract

Foxtail millet is a climate-resilient cereal crop that is growing in importance in food security and sustainable agriculture. This study aimed to identify panicle traits associated with yield, determine functional traits suitable for selecting high-productivity genotypes, and classify superior local Indonesian foxtail millet genotypes. Eight genotypes were evaluated using a randomized complete block design with three replications. Correlation analysis of 31 panicle traits revealed that grain filling rate, panicle weight, grain weight per panicle, grain weight per plant, and grain numbers on the middle and lower primary branches were positively associated with yield. Several of these traits also exhibited high broad-sense heritability and moderate GCV and PCV values, indicating their potential for selection. Principal component and two-way heatmap cluster analyses identified Buru, ICERI-7, Hambapraing, and Mauliru-2 as high-yielding genotypes. The findings provide critical insights for foxtail millet breeding programs in Indonesia focused on improving yield.

Abstract

Caffeic acid O-methyltransferase (COMT) is an essential enzyme that catalyzes the biosynthesis of lignin monomer units. Foxtail millet (Setaria italica) possesses three COMT-encoding genes. However, only SiCOMT1 and SiCOMT2 are considered expressed. This study investigates the characteristics of the two COMT-encoding genes across nine Indonesian foxtail millet genotypes. Phylogenetic analysis revealed that SiCOMT1 is closely related to N-methyltransferase genes, which are not involved in the lignin biosynthesis pathway. Meanwhile, SiCOMT2 is closely related to O-methyltransferase genes involved in lignin biosynthesis. SiCOMT2 from nine Indonesian foxtail millet genotypes exhibits 15 synonymous and three non-synonymous SNPs. SiCOMT2 amino acid showed Ala67Thr and Pro72Ala variations within the methyltransferase dimerization domain, and Glu146Asp within the O-methyltransferase domain. Among these, the Pro72Ala substitution is predicted to reduce the structural stability of the encoded protein. These findings suggest that SiCOMT2 may serve as a promising target for future genetic research and crop improvement strategies aimed at enhancing biomass quality by modifying lignin content and composition.
