Nonsymbiotic hemoglobin-2 leads to an elevated energy state and to a combined increase in polyunsaturated fatty acids and total oil content when overexpressed in developing seeds of transgenic Arabidopsis plants.

Comments	"Seeds of various species have been found to develop in an internal environment with about 2% to 4% (v/v) oxygen, compared with 21% (v/v) oxygen outside (Porterfield et al., 1999 Gibon et al., 2002 Rolletschek et al., 2002, 2005, 2007 Geigenberger, 2003 Vigeolas et al., 2003, van Dongen et al., 2004).
