“…Wateruse efficiency and stomatal conductance significantly decreased under prolonged waterlogging, whereas leaf water potential (ψL) remained constant, indicating stomatal closure in the absence of water stress (Ahmed et al 2002). Several ROS were generated due to oxidative damage associated with the excessive decrease in the electron transport chain (ETC) during waterlogging/flooding circumstances (Lal et al 2019).…”

“…It indicates the declined photosynthetic rate is coupled with stomatal factors (Mielke et al 2003, Wang et al 2019, Minhas et al 2020. Under the circumstances of waterlogging/flooding/hypoxia due to excessive reduction of electron transport chain (ETC), oxidative damage and production of ROS have been taking place (Lal et al 2019).…”

“…In addition, decreases in leaf nitrogen content, leaf water potential, stomatal conductance, CO 2 assimilation rate and photosynthesis, as well as accelerated leaf chlorosis and senescence may also be observed [ 15 , 17 ]. The down-regulation of the photosynthetic machinery in waterlogging sensitive plants results in the excessive production of reactive oxygen species (ROS) causing severe oxidative damage and degradation of cellular structures, interfering with normal metabolism [ 10 , 18 ]. ROS cause lipoperoxidation phenomena resulting in membrane injury, protein degradation, enzyme inactivation, damage to nucleic acids and, eventually, cell death [ 19 , 20 , 21 , 22 ].…”

Inundation, excessive precipitation, or inadequate field drainage can cause waterlogging of cultivated land. It is anticipated that climate change will increase the frequency, intensity, and unpredictability of flooding events. This stress affects 10–15 million hectares of wheat every year, resulting in 20–50% yield losses. Since this crop greatly sustains a population’s food demands, providing ca. 20% of the world’s energy and protein diets requirements, it is crucial to understand changes in soil and plant physiology under excess water conditions. Variations in redox potential, pH, nutrient availability, and electrical conductivity of waterlogged soil will be addressed, as well as their impacts in major plant responses, such as root system and plant development. Waterlogging effects at the leaf level will also be addressed, with a particular focus on gas exchanges, photosynthetic pigments, soluble sugars, membrane integrity, lipids, and oxidative stress.

“…Besides those damages, there is an increase in reactive oxygen species (ROS) formation, indicating oxidative damage that directly affects the maintenance of cell homeostasis, causing damages to proteins, lipids, carbohydrates and nucleic acids (DNA and RNA) (Lal et al, 2019). Among the most important ROS stand out the superoxide anion (O 2 -), hydrogen peroxide (H 2 O 2 ), and the hydroxyl radical (OH -) that in conditions of hypoxia accumulates in the leaves along with an increase in malondialdehyde (MDA) (Fukao et al, 2019).…”

Waterlogging effects upon the phenological phases of common bean cultivar BRSMG-Uai

et al. 2020

Common bean (Phaseolus vulgaris L.) is an important source of protein and carbohydrates, besides being rich in several mineral nutrients. In a flooding situation, the low availability of oxygen may result in hypoxia or anoxia condition. Therefore, this study aimed to evaluate the responses of the common bean cultivar BRSMG-Uai subjected to hypoxia in different phenological phases, analyzing its responses in terms of growth, productivity, carbon and nitrogen metabolism. Thus, seeds of common beans were germinated and when the seedling reached growth stage V1, they were transferred to plastic boxes containing 40L of nutritive solution with steady aeration. Distinct series of plants were exposed to air-restriction on their roots for nine days, in three different phenological phases V3/V4, R6 and R7. Samples were collected for biochemical and growth analyses in a completely random design (n=6). The plants subjected to low availability of oxygen presented a reduction in bean number, displaying the greatest loss in productivity in V3/V4, conferring the highest sensitivity to hypoxia in this phase. On the other hand, there was an increase in sugar concentration in leaves, and it was also possible to observe an increase in hydrogen peroxide in leaves and roots, concomitant with a decrease in superoxide dismutase activity in all phenological phases. There was also an increase in ascorbate peroxidase activity in roots in R6, as well as in nitrate reductase activity. We conclude that the cultivar BRSMG-Uai presents sensitivity to low oxygen availability, and the phenological phaseV3/V4 is the most critical for it.
