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

a

Only significant polymorphic sites are shown.

b

Alleles 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.

c

2008NJ 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.

d

Phenotypic 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.

e

P value from the MLR analysis of the data across three environments.

f

Fold 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.
