“…Since then, numerous studies (e.g. Keppler et al ., 2008; Wang et al ., 2008; Brüggemann et al ., 2009; Bruhn et al ., 2009, 2014; Martel & Qaderi, 2017, 2019) have confirmed aerobic CH 4 emissions from terrestrial plants. During the past decade, tree stems from tropical to boreal forests and trees growing under varying hydrological conditions have been found to emit CH 4 through multiple mechanisms behind the emissions (Carmichael et al ., 2014; Barba et al ., 2019).…”

Methane (CH 4 ) exchange in tree stems and canopies and the processes involved are among the least understood components of the global CH 4 cycle. Recent studies have focused on quantifying tree stems as sources of CH 4 and understanding abiotic CH 4 emissions in plant canopies, with the role of microbial in situ CH 4 formation receiving less attention. Moreover, despite initial reports revealing CH 4 consumption, studies have not adequately evaluated the potential of microbial CH 4 oxidation within trees. In this paper, we discuss the current level of understanding on these processes. Further, we demonstrate the potential of novel metagenomic tools in revealing the involvement of microbes in the CH 4 exchange of plants, and particularly in boreal trees. We detected CH 4 -producing methanogens and novel monooxygenases, potentially involved in CH 4 consumption, in coniferous plants. In addition, our field flux measurements from Norway spruce (Picea abies) canopies demonstrate both net CH 4 emissions and uptake, giving further evidence that both production and consumption are relevant to the net CH 4 exchange. Our findings, together with the emerging diversity of novel CH 4 -producing microbial groups, strongly suggest microbial analyses should be integrated in the studies aiming to reveal the processes and drivers behind plant CH 4 exchange.

“…Overall, these findings suggest a complex nature of interactions among environmental factors. As shown, individual stress factors usually have adverse effects on plant dry mass, leading to increased CH 4 emissions (Martel and Qaderi 2019); however, the interactive effects of environmental factors differ from those of individual factors, as shown in this study. In conclusion, environmental stress factors increased CH 4 emissions from flowers and pods, and that increased emissions had an inverse relationship with the dry mass of these reproductive organs.…”

“…More than a decade ago, Keppler et al (2006) reported that terrestrial plants emit CH 4 under aerobic conditions. Subsequent studies have suggested various compounds as potential precursors (Bruhn et al 2012;Liu et al 2015;Martel and Qaderi 2019) and used different approaches to investigate aerobic CH 4 emissions from plants (Dueck et al 2007;McLeod et al 2008;Vigano et al 2008;Qaderi and Reid 2009;Abdulmajeed and Qaderi 2017). For example, Dueck et al (2007) used laser-based measuring techniques in conjunction with stable isotope 13 C to measure aerobic CH 4 emissions from terrestrial plants and concluded that the emission levels were not substantial.…”

“…For example, Dueck et al (2007) used laser-based measuring techniques in conjunction with stable isotope 13 C to measure aerobic CH 4 emissions from terrestrial plants and concluded that the emission levels were not substantial. Methane emission from plants is actually one of the many physiological responses of plants to environmental stressors, such as high temperature, enhanced UVB radiation (Liu et al 2015), water deficit Reid 2009, 2011), and blue light (Martel and Qaderi 2019).…”

Environmental stressors increase methane (CH 4) emissions from plants. Few studies have investigated the interactive effects of multiple abiotic factors on CH 4 emissions from plant vegetative organs and almost none from reproductive organs. We examined the combined effects of temperature, ultraviolet-B radiation, and watering regime on aerobic CH 4 emissions from plant reproductive parts. Pea (Pisum sativum L. cv. 237J Sundance) plants were grown under two temperature regimes (22/18°C and 28/24°C; 16 h light/8 h dark), two levels of UVB radiation (0 and 5 kJ m-2 day-1), and two watering regimes (field capacity and wilting point) in controlled-environment growth chambers for over a month, after one week of initial growth under 22/18 o C. Then, CH 4 emissions were measured from fully-opened flowers and pods (1-, 5-, and 10-day-old). Higher temperatures decreased flower dry mass, but significantly increased CH 4 emissions from flowers. Other individual environmental factors did not affect flower and pod dry mass or CH 4 emission. In some cases, however, interactions between or among factors significantly affected pod dry mass and CH 4 emissions from flowers and pods, suggesting the synergistic effects of environmental factors on plant-derived CH 4. In conclusion, stress factors increased flower and pod CH 4 emissions, which had inverse relationships with dry mass of reproductive organs.

“…Pea leaves release CH 4 at high temperatures [12]. Recently, Martel and Qaderi [69] found that CH 4 is also produced in canola under blue light ( Figure 1). Interestingly, Messenger et al [70] found that CH 4 is produced in citrus fruit under ultraviolet radiation (UV) when UV reacts with its photosensitizer to produce hydroxy radicals (·OH), which causes the pectin methyl group to form CH 4 .…”

Abiotic stress is one of the major threats affecting plant growth and production. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Recently, the study of gasotransmitters in plants has attracted much attention, especially for abiotic stress. In the present review, abiotic stressors were mostly found to induce gasotransmitter production in plants. Meanwhile, these gasotransmitters can enhance the activity of several antioxidant enzymes, alleviate the harmfulness of ROS, and enhance plant tolerance under various stress conditions. In addition, we introduced the interaction of gasotransmitters in plants under abiotic stress. With their promising applications in agriculture, gasotransmitters will be adopted in the near future.Plants 2019, 8, 605 2 of 23 unique and regulate specific biological functions. Gasotransmitters have long been of great interest in a wide range of fields. Over the past few decades, the roles of these signaling molecules have been extensively studied for their biological applications. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitter signaling pathways. Previous studies found that in response to abiotic stressors, plants usually produce these gasotransmitters [12][13][14]. In addition, there is now considerable evidence to show that gasotransmitters can play a pivotal role in enhancing plant tolerance [2,15,16]. Subsequently, biological gases from complex extra and intracellular pathways and gas mediators may regulate many processes in an antagonistic or synergistic way.In the present review, we introduce the production of gasotransmitters in plants under abiotic stress. Meanwhile, we focused on the recent advances in the roles of gasotransmitters under abiotic stresses and their interaction with other gasotransmitters.
