These findings in rice complement data from other genera
(i.e. Arabidopsis, Lotus, Poplar, Potamogeton, and
Rumex) suggesting there exists a conserved flooding
response network in plants that includes ethylene-triggered
alterations in gene expression leading to growth and
stress-induced catabolism of stored or soluble carbohydrates
for energy-efficient production and utilization
of ATP. A key challenge is to decipher the interplay
between hormones (i.e. ethylene, abscisic acid (ABA),
and gibberellic acids (GA)), oxygen availability, and
specific metabolites (i.e. ATP, sugars, and pyruvate) that
drives a dynamic network balancing growth and quiescence
to facilitate survival (Figure 1)
