Stress including both abiotic and biotic factors is a major determining factor that affects the growth and development of crops to attain their full ability to produce yield or genetic potential. Among these, waterlogging or submergence is the major detrimental leading to anoxia, soil saturation and hypoxia ultimately resulting in a reduction in production and yield. The majority of field crops are prone and vulnerable to water stress at some point during their critical growth and development. It has been estimated recently that around 12% of the arable land is frequently affected by waterlogging and leading to a reduction in 20% of yield and in nearing future, this could possibly increase due to climate change. For instance, soybean is highly prone to water stress (waterlogging) during its germination, emergence and grain-filling stages. Submergence susceptibility is another major concern for staple crops such as wheat, rice, barley and maize. Some of the most common damages associated include necrosis, stunted growth, defoliation, poor yield and reduction in the availability of nutrients and sometimes even death. Identification of susceptible or resistant lines is crucial for the development of tolerant lines through traditional breeding approaches and can be followed with marker-assisted selection for the development of resistant varieties. Despite all, there are no commercially available waterlogging tolerant varieties of crops.
The objective of this research topic is to present the current scientific evidence and insights on waterlogging on different agronomically important crops by emphasizing the effect of waterlogging on morphology (morphological/anatomical adaptations), physiological, biochemical, genomic and genetic modifications followed by the identification of lines for breeding for crop improvement which later can be used for the development of tolerant varieties.
In the near future, climate change predicts frequent flooding events across the globe which in turn cause a serious threat to food security crops. These irregular and unusual fluctuations cause huge yield and production losses thereby affecting food production, especially import/export (e.g. soybean). This topic aims to highlight the broad area of crop native and alternative anaerobiosis. This research topic invites systematic review and research articles under the below mentioned themes or subtopics (but not limited to) for all agriculturally important crops:
• Components involved during flooding stress, how plants sense their environment and respond through signaling, in order to produce and develop resistant varieties.
• Anatomical, physiological, biochemical, molecular level responses and adaptations made of plants during waterlogged conditions.
• Unravelling underlying genetic mechanisms through which plants cope or withstand such stress
• Identification of genes and key (regulatory) processes involved.
• Quantitative trait loci (QTL) associated with waterlogging tolerance-related traits involved in it,
• Construction of association mapping and simultaneously elucidating the genetic basis for discovering novel tolerance mechanisms.
• Development of resistant varieties (waterlogging tolerant germplasm) through translating the traits into crops through either traditional breeding or modern genome editing techniques.
• Identification of lines for breeding for crop improvement and breeding strategies to overcome waterlogging.
