Comparative proteomic analysis revealing the tolerance mechanism associated with waterlogging stress in sesame

Sesame is typically considered drought-tolerant but susceptible to waterlogging, a property that can be ascribed to its suspected origin in Africa or India and its subsequent dispersal to tropical or semitropical regions. Low yield may be attributed to several reasons, but waterlogging is a primary factor that has a severe effect in countries such as China and Korea due to changing climate. In the case of Korea, the demand for cultivation area of the crops in the paddy field is increasing. At the same time, rainfall is concentrated in the summer season, which is the primary growth period of the plant, and the precipitation amount of the specific period is increased according to the abnormal weather, and the frequency of the waterlogging is rising. Protein is an essential molecule that participates in enzymes that act as catalysts for various chemical reactions in cells, hormones with regulatory functions, in vivo reactions and energy metabolism. These proteins are very diverse in different kinds of plants and also in various organs in plants, and the expression pattern varies depending on the growth stage of the plant and the environment in which the plant is located.
