Molecular aspects of the antagonistic interaction of smoke-derived butenolides on the germination process of Grand Rapids lettuce (Lactuca sativa) achenes

Original language description

Smoke-derived compounds provide a strong chemical signal to seeds in the soil seed bank, allowing them to take advantage of the germination niche created by the occurrence of fire. The germination stimulatory activity of smoke can largely be attributed to karrikinolide (KAR1), while a related compound, trimethylbutenolide (TMB), has been shown to have an inhibitory effect on germination. The aim of this study was to characterize the interaction of these potent firegenerated compounds. Dose-response analysis using highly KAR1-sensitive lettuce (Lactuca sativa cv 'Grand Rapids') achenes demonstrated that the compounds are not competitors and TMB modulates germination in a concentration-dependent manner.The transcriptome analysis revealed a contrasting expression pattern induced by the compounds. KAR1 suppressed, while TMB up-regulated ABA, seed maturation and dormancy-related transcripts. The effect of TMB was reversed by leaching the compound, while the KAR1 effect was only reversible b
