Physiological and biochemical changes in plants under waterlogging

Abstract: Waterlogging usually results from overuse and/or poor management of irrigation water and is a serious constraint with damaging effects. The rapidly depleting oxygen from submerged root zone is sensed and plant adjusts expressing anaerobic proteins. Plant cells shift their metabolism towards low energy yielding anaerobic fermentation pathways in the absence of oxygen. Structural modifications are also induced as aerenchyma formation and adventitious rootings, etc. Studies at molecular and biochemical levels to … Show more

“…This balance may be altered by both natural and anthropic factors (Morales-Olmedo et al, 2015). Human related causes include poor irrigation management and soil compaction, while natural flooding are caused by excessive rain (Irfan et al, 2010). In both cases soils with high clay content and/or compaction due to agricultural practices are susceptible to soil waterlogging (Morales-Olmedo et al, 2015).…”

“…The O 2 supply to the roots might directly affect the response to waterlogging, irrespective of [CO 2 ]. Decreased O 2 supply to the roots under waterlogging can inhibit all plant metabolic functions (Colmer, 2003;Sojka et al, 2005;Irfan et al, 2010). Sojka et al (2005) reviewed the interactions between stomatal conductance and both soil temperature or soil O 2 concentration, and showed that the relationship between the conductance and soil temperature was diminished at low O 2 concentrations.…”

“…In addition, elevated [CO 2 ] can increase root size (Kimball et al, 2002), which might permit an increase in root air space and aerenchyma to supply O 2 from above the ground. Although air space and aerenchyma are critical factors in waterlogging tolerance (Thomson et al, 1990;Boru et al, 2003;Shimamura et al, 2003;Sojka et al, 2005;Irfan et al, 2010), the effects of elevated [CO 2 ] on root air space and aerenchyma have not been reported.…”

“…The formation of ethylene induced the auxin mediating the aerenchyma formation below the root tip (Irfan, Hayat, S., Hayat, Q., Afroz, & Ahmad, 2010). Aerenchyma is the space between the cell which develop maximum and commonly found in the stem and root of hydrophytic plants.…”
