Abstract
Flooding stress, in addition to drought and salinity, is a critical problem in agriculture worldwide as it results in reduced plant biomass and yield. During flooding, plants are adversely affected by deep-water submergence, which leads to hypoxic stress and affects the water-holding capacity of the soil. The root is the first organ to perceive flooding stress in plants and plays an important role in plant growth by facilitating the uptake of water and nutrients. Under adverse flooding conditions like waterlogging, roots are known to undergo morphological and anatomical changes. In addition to the observable anatomical changes, roots also undergo underlying transcriptomic and epigenetic changes in response to the flood. The interaction of various hormones, primarily including ethylene, through intricate signaling, also participates in the management of flooding response. This chapter summarizes the responses and acclimation of roots to flooding, focusing on their morphological and anatomical adaptations. Furthermore, we will explore transcriptome and hormone-regulated abscisic acid-dependent and independent responses to flooding in plants.
