Soybean exhibits natural variation in flower and seed coat colors via the deposition of various anthocyanin pigments in the respective tissues. Although pigmentation in seeds or flowers has been well dissected at molecular level in several plant species, the genes controlling natural variation in anthocyanin traits in the soybean are not completely understood. To evaluate the genetic correlation between genetic loci and genes, 8 enzyme-encoding gene families and a transcription factor were localized in a soybean genome-wide genetic map. Among the seed coat color–controlling loci, the genetic location of the gene encoding for W1 was substantiated in the context of the current soybean molecular genetic map and O was postulated to correspond to anthocyanidin reductase. Among the genetic loci that regulate flower pigmentation, the genetic locations of the genes encoding for W1, W4, and Wp were identified, W3 was mapped on soybean linkage group B2 (chromosome 14), and W2 was postulated to correspond to an MYB transcription factor. Correlation studies between the developed markers and 3 color-controlling loci provided important empirical data that should prove useful in the design of marker-assisted breeding schemes as well as future association studies involving soybean.

The investment boundaries defined by Grenadier (2002) for an oligopoly investment game determine equilibria in open-loop strategies. As closed-loop strategies, they are not equilibria, because any firm by investing sooner can preempt the investments of other firms and expropriate the growth options. The perfectly competitive outcome is produced by closed-loop strategies that are mutually best responses. In this equilibrium, the option to delay investment has zero value, and the simple NPV rule is followed by all firms.
