• Four synthetic pathways of CH 4 were identified in plants. • CH 4 is involved in plant growth and development. • CH 4 plays an important role in plant abiotic stress response. • CH 4 may interact with other signaling molecules. • CH 4 regulates the expression of some genes. Methane (CH 4), a tetrahedral molecule, has been shown to be a signaling molecule in animals and plants. Here, the synthesis of CH 4 was introduced, and 4 pathways of CH 4 production in plants were summarized. Many studies show that CH 4 might be involved in plant growth and development, including seed germination, seedling growth, lateral rooting, adventitious rooting and postharvest freshness. CH 4 also plays an important role in plant response to abiotic stresses, such as salt stress, osmotic stress and heavy metal stress. For example, CH 4 could generally enhance the abiotic stress resistance of plants by enhancing the antioxidant defense system. In addition, CH 4 displays crosstalk with other signal molecules, including nitric oxide (NO), Hydrogen sulfide (H 2 S), Carbon monoxide (CO), calcium (Ca2+), hydrogen peroxide (H 2 O 2) and auxin. CH 4 also regulates the expression of response genes under abiotic stress and in lateral and adventitious root formation. In the future studies, more attention should be paid to the synthesis molecular mechanism of CH 4 in plants and its crosstalk with phytohormone. [ABSTRACT FROM AUTHOR]
