Qi, Z.-m., Sun Y.-n., Wu, Q., Liu, C.-y., Hu, G.-h. and Chen, Q.-s. 2011. A meta-analysis of seed protein concentration QTL in soybean. Can. J. Plant Sci. 91: 221-230. An integrated map of QTLs related to seed protein concentration in soybean has been constructed, based on the public genetic map, soymap2 as a reference map, along with a set of 107 QTLs reported in the literature over the past 20 yr. Each of these QTLs was projected onto the soymap2 by software package BioMercator v2.1. Twenty-three consensus QTLs were detected. The confidence interval at all sites ranged from 1.52 to 14.31cM, and the proportion of the phenotypic variance associated with each of them from 1.5 to 20.8%. Major chromosomal sites were identified on LG I (Gm20), four important sites were identified, involving LG A1 (Gm05), B2 (Gm14), E (Gm07) and M (Gm15). A meta-analysis approach was used to improve the precision of the location of these sites. These results facilitate gene mining and molecular assist-selection in soybean.
