GmACP1 polymorphisms associated with phosphorus (P) efficiency traits in diverse soybean accessions.

aOnly significant polymorphic sites are shown.bAlleles in series are listed for each polymorphism, and favorable alleles (higher RAPA and RPC) are indicated in bold.InDel170 allelic series: 1, no deletion; 2, 6 bp deletion; 3, 8 bp deletion; 4, 9 bp deletion; 5, 10 bp deletion. InDel423 allelic series: 1, 1 bp deletion; 2, 4 bp deletion; 0, 0 bp deletion.c2008NJ and 2008HN denote the 2008 field experiments at Nanjing and Henan, China. P values are from an association analysis performed using the mixed model, incorporating population structure and kinship, using data from two years and two sites.dPhenotypic data across three environments were used for the analysis. R2 values from multiple linear regression (MLR) of the data showing the percentage phenotypic variation explained.eP value from the MLR analysis of the data across three environments.fFold change between two of the most differentiated haplotype classes.ns: not significant at P = 0.05; RAPA: relative acid phosphatase activity in two P conditions; RPC: relative P concentration in two P conditions.
