“…These reports clarified that stimulatory effects of smoke continue in post-germination stages and may enhance the biomass of the plants. The post-germination studies of smoke-treated seeds elucidate that although smoke treatment may not affect the germination stage, it still may promote growth at the post-germination stage [ 75 ]. It is, therefore, recommended to extend all germination studies necessarily up to the seedling stage so that the post-germination effects of plant-derived smoke can be interpreted.…”

The role of plant-derived smoke, which is changed in mineral-nutrient status, in enhancing germination and post-germination was effectively established. The majority of plant species positively respond to plant-derived smoke in the enhancement of seed germination and plant growth. The stimulatory effect of plant-derived smoke on normally growing and stressed plants may help to reduce economic and human resources, which validates its candidature as a biostimulant. Plant-derived smoke potentially facilitates the early harvest and increases crop productivity. Karrikins and cyanohydrin are the active compound in plant-derived smoke. In this review, data from the latest research explaining the effect of plant-derived smoke on morphological, physiological, biochemical, and molecular responses of plants are presented. The pathway for reception and interaction of compounds of plant-derived smoke at the cellular and molecular level of plant is described and discussed.

“…In this technique, smoke was generated in a drum, and using compressed air, was bubbled through distilled water [ 33 ]. A wide range of plant materials has been used to generate aqueous smoke extracts using this technique [ 1 , 29 , 30 , 47 ]. Studies have shown that all plant materials produce similar chemical compositions and can be applied in diluted forms ranging from 1:10 to 1:100, v / v [ 48 ] or 1000–2000 ppm [ 2 ] to enhance germination events.…”

“…Studies have shown that all plant materials produce similar chemical compositions and can be applied in diluted forms ranging from 1:10 to 1:100, v / v [ 48 ] or 1000–2000 ppm [ 2 ] to enhance germination events. However, a recent study has shown that the dilution ratio of smoke water and distilled water 1:2500 ( v / v ) from the sub-dilution 25:75 ( v / v ) of smoke water was the best for the germination of lettuce seeds in the dark, achieving a 91% germination rate against the water control that had only 7–10% germination [ 47 ]. Although these dilution ranges have been found to be effective to promote the germination events, the response varies widely across plant species.…”

“…De Lange and Boucher (1990) demonstrated that active component(s) of gas phase smoke are water-soluble and that a smoke-saturated solution is effective in improving seed germination [ 33 ]. Since then bioactive compounds having either stimulatory or inhibitory activity on seed germination have been identified in smoke [ 47 , 52 ]. Both organic and inorganic chemicals originating or released from smoke help stimulate the germination of seeds.…”

The success of seed germination and the successful establishment of seedlings across diverse environmental conditions depends on seed vigour, which is of both economic and ecologic importance. The smoke-derived exogenous compound karrikins (KARs) and the endogenous plant hormone strigolactone (SL) are two classes of butanolide-containing molecules that follow highly similar signalling pathways to control diverse biological activities in plants. Unravelling the precise mode-of-action of these two classes of molecules in model species has been a key research objective. However, the specific and dynamic expression of biomolecules upon stimulation by these signalling molecules remains largely unknown. Genomic and post-genomic profiling approaches have enabled mining and association studies across the vast genetic diversity and phenotypic plasticity. Here, we review the background of smoke-assisted germination and vigour and the current knowledge of how plants perceive KAR and SL signalling and initiate the crosstalk with the germination-associated hormone pathways. The recent advancement of ‘multi-omics’ applications are discussed in the context of KAR signalling and with relevance to their adoption for superior agronomic trait development. The remaining challenges and future opportunities for integrating multi-omics datasets associated with their application in KAR-dependent seed germination and abiotic stress tolerance are also discussed.

“…Quantification of KARs in smoke water using ultrahigh-performance liquid chromatography-tandem mass spectrometry revealed differences in both total and relative levels of KAR [28]. The smoke water prepared by different protocols needs to be dissolved in different ratios due to the variable content of germination stimulators and inhibitors [29]. Therefore, utilization of KARs rather than aerosol smoke or smoke-water is convenient for research and agriculture, despite the lower price of aerosol smoke and smoke-water compared to KARs [30].…”

Karrikins (KARs) have been identified as molecules derived from plant material smoke, which have the capacity to enhance seed germination for a wide range of plant species. However, KARs were observed to not only impact seed germination but also observed to influence several biological processes. The plants defected in the KARs signaling pathway were observed to grow differently with several morphological changes. The observation of KARs as a growth regulator in plants leads to the search for an endogenous KAR-like molecule. Due to its simple genomic structure, Arabidopsis (Arabidopsis thaliana L.) helps to understand the signaling mechanism of KARs and phenotypic responses caused by them. However, different species have a different phenotypic response to KARs treatment. Therefore, in the current work, updated information about the KARs effect is presented. Results of research on agricultural and horticultural crops are summarized and compared with the findings of Arabidopsis studies. In this article, we suggested that KARs may be more important in coping with modern problems than one could imagine.
