“…Karrikinolides (KAR1-KAR6) are butenolide compounds that were first discovered as post-fire germination stimulators in plants [14,46]. Present in smoke and its formulations, they affect cell metabolism by interacting with phytohormones such as ABA, GA, IAA and ethylene, which initiates specific signal transduction and gene expression [47]. However, the responses of model and arable plants to karrikin are not always similar and vary in terms of growth, development and photosynthetic characteristics.…”

Smoke is one of the fire-related cues that can alter vegetation communities’ compositions, by promoting or excluding different plant species. For over 30 years, smoke-derived compounds have been a hot topic in plant and crop physiology. Research in this field was initiated in fire-prone areas in Australia, South Africa and some countries of both Americas, mostly with Mediterranean-type climates. Then, research extended to regions with moderate climates, like Central European countries; this was sometimes determined by the fact that in those regions, extensive prescribed or illegal burning (swailing) occurs. Hence, this review updates information about the effects of smoke compounds on plant kingdoms in different regions. It also focuses on research advances in the field of the physiological effects of smoke chemicals, mostly karrikins, and attempts to gather and summarize the current state of research and opinions on the roles of such compounds in plants’ lives. We finish our review by discussing major research gaps, which include issues such as why plants that occur in non-fire-prone areas respond to smoke chemicals. Have recent climate change and human activities increased the risk of wildfires, and how may these affect local plant communities through physiologically active smoke compounds? Is the response of seeds to smoke and smoke compounds an evolutionarily driven trait that allows plants to adapt to the environment? What can we learn by examining post-fire smoke on a large scale?

“…Smoke and its active compounds affect cell metabolism by interacting with phytohormones such as ABA, GA, IAA and ethylene [40]. The smoke produced from the burning of plants consists of various complex chemical compounds, and this variation may be the reason behind the different responses of plants to smoke [12].…”

“…Concentrations of butenolides and other smoke-derived compounds can have adverse effects on germination. Hydroquinone is a strong bioactivator that is only active at low concentrations, and its high concentrations decrease KAR1 activity and inhibits seed germination [40]. Under various conditions like abiotic stresses, karrikin increased several abscisic acid signaling pathway genes including ABI5, ABI3, RELATED PROTEIN KINASE2.6,-SNF1 RELATED PROTEIN KINASE2.3,-NF1 without an increase in ABA.…”

Fire-related cues could alter vegetation community composition by promoting or excluding different types of plants. Smoke-derived compounds have been a hot topic in plant and crop physiology. There are some fire-prone areas in Australia, both Americas, some Mediterranean countries and regions with extensive prescribed or illegal burning like central European, which are subjected to a direct impact of fire (heat, minerals accumulation from the burning matter) and/or the indirect one (smoke) and undergo compositional and structural changes. This review first updates information about the effect of the compounds on plants' kingdoms and focuses on the research advances in the field of smoke compounds and attempts to gather and summarize the recent state of research and opinions on the role of smoke-derived compounds in plants' lives. We finish our review by discussing major research gaps, which include: Why plants respond to smoke chemicals? Is the response of seeds to smoke and smoke compounds an evolutionary-driven trait allowing plants to adapt to local environment?

“…17 In addition to normal growth parameters, smoke water also helps reduce the stress effects in plants. 18 Moringa oleifera -derived smoke water reduced the impact of cadmium stress and improved the physiological and biochemical parameters of rice. 19 In another study, smoke water obtained from rice straw has modulated the oxidative stress and subsequently enhanced root growth.…”

Biostimulants are obtained from various sources like plants, animals, microorganisms, and industrial by-products as well as waste material. Their utilization in agriculture practices is being increased that is giving positive results. The purpose of the current study was to use plant-derived smoke (SMK) solution and biogas digestate (BGD) slurry as biostimulant to elucidate their impact on potato ( Solanum tuberosum ) performance. The experiment was conducted in lab as well as field conditions, and SMK and BGD solutions were prepared in varying concentrations such as SMK 1:500, SMK 1:250, BGD 50:50, and BGD 75:25. Foliar applications were performed thrice during experiments and data were collected related to photosynthesis, growth, pigments, and genome-wide methylation profiling. Net photosynthesis rate ( A ) and water use efficiency (WUE) were found higher in SMK- and BGD-treated lab and field grown plants. Among pigments, BGD-treated plants depicted higher levels of Chl a and Chl b while SMK-treated plants showed higher carotenoid levels. Alongside, enhancement in growth-related parameters like leaf number and dry weight was also observed in both lab- and field-treated plants. Furthermore, DNA methylation profile of SMK- and BGD-treated plants depicted variation compared to control. DNA methylation events increased in all the treatments compared to control except for SMK 1:500. These results indicate that smoke and slurry both act as efficient biostimulants which result in better performance of plants. Biostimulants also affected the genome-wide DNA methylation profile that resultantly might have changed the plant gene expression profiling and played its role in plant responsiveness to these biostimulants. However, there is need to elucidate a possible synergistic effect of SMK and BGD on plant growth along with gene expression profiling.
