Table 1. Alleles of the mutants at the GmPPD loci.

Mutant lines	GmPPD1 locus	GmPPD2 locus	Morphological evaluation1
ppd1	7-nucleotide deletion	45-nucleotide deletion	Moderate phenotype alteration
ppd2	39-nucleotide deletion	2-nucleotide insertion	Moderate phenotype alteration
ppd-KO	7-nucleotide deletion	2-nucleotide insertion	Severe phenotype alteration

¹Morphological evaluation was based on the characteristics described by Kanazashi et al. (2018).
