摘要： Flowering time and plant height are key agronomic traits that directly affect soybean (Glycine max) yield.APETALA1(AP1) functions as a class A gene in the ABCE model for floral organ development, helping to specify carpel, stamen, petal, and sepal identities. There are fourAP1homologs in soybean, all of which are mainly expressed in the shoot apex. Here, we used clustered regularly interspaced short palindromic repeats (CRISPR) - CRISPR-associated protein 9 technology to generate a homozygous quadruple mutant,gmap1, with loss-of-function mutations in all fourGmAP1genes. Under short-day (SD) conditions, thegmap1quadruple mutant exhibited delayed flowering, changes in flower morphology, and increased node number and internode length, resulting in plants that were taller than the wild type. Conversely, overexpression ofGmAP1aresulted in early flowering and reduced plant height compared to the wild type under SD conditions. Thegmap1mutant and the overexpression lines also exhibited altered expression of several genes related to flowering and gibberellic acid metabolism, thereby providing insight into the role ofGmAP1in the regulatory networks controlling flowering time and plant height in soybean. Increased node number is the trait with the most promise for enhancing soybean pod number and grain yield. Therefore, the mutant alleles of the fourAP1homologs described here will be invaluable for molecular breeding of improved soybean yield.
