1. Primed plants could maintain higher chlorophyll content, greater photosynthesis capacity and enhanced light use efficiency (Li et al. 2011).
2. Enhanced stress tolerance to later waterlogging stress by priming was also reported by Wang et al. (2016).
3. Roots are the first to sense the hypoxia under waterlogging.
4. Waterlogging leads to hypoxia, consequently, promotes early senescence of leaves, death of seminal roots, restriction of adventitious root length, affects carbohydrate metabolism, and overall reduced growth (Tan et al. 2008; Herzog et al. 2016).
