This soybean study uncovered 101 Quantitative Trait Nucleotides (QTNs) associated with flowering responses to photo-thermal conditions. Three candidate genes—Glyma.08G302500 (GmHY5), Glyma.08G303900 (GmPIF4c), and Glyma.16G046700 (GmVRN1)—exhibited non-synonymous substitutions. Using a diverse panel of 201 cultivars, a genome-wide association study assessed thermal response (TR) and interactive photo-thermal response (IPT) for soybean flowering time. The study identified SNPs […]
