A highly active, heat stable, long lasting compound, 3- methyl-2H-furo[2,3-c]pyran-2-one (1), that stimulates seed germination was isolated from plant-derived smoke water using bioactivity-guided fractionation. The identification of this natural molecule, the major germination cue from smoke, should now rapidly lead to a more comprehensive understanding of the role of smoke as a promoter of seed germination.

• Butenolide from plant-derived smoke enhances germination and seedling growth of arable weed species (2006, methodology): “The butenolide used in the experiments was isolated, purified and identified from smokesaturated water derived from burned Passerina vulgaris Thoday and Themeda triandra L. as described by Van Staden et al. (2004).”
• Smoke-derived butenolide: Towards understanding its biological effects (2009, unknown): “…et al., 2007), hemi- and holo-parasitic weeds (Daws et al., 2008), several Australian Solanum spp. (Commander et al., 2008) and crop plants including lettuce, tomato, okra, bean, maize and rice (Van Staden et al., 2004; Jain and Van Staden, 2006; Kulkarni et al., 2006; Van Staden et al., 2006).”
• Seed germination of agricultural weeds is promoted by the butenolide 3-methyl-2H-furo[2,3-c]pyran-2-one under laboratory and field conditions (2007, methodology): “The remarkable activity of the butenolide (germination promotion at <0.67 nM; Flematti et al. 2004, 2007; van Staden et al. 2004, 2006; Merritt et al. 2006) means that for the first time a method of applying smoke technology (and germination stimulants) to management of weeds in agricultural…”
