Description:Flooding stress\, including soil waterlogging and partial to co
 mplete submergence\, reduces oxygen availability for ATP production\, trig
 gering alterations in gene expression and energy metabolism.  The plant-s
 pecific Group VII Ethylene Response Factor (ERF) transcription factors hav
 e emerged as pivotal regulators of flooding and low oxygen responses. Seve
 ral Arabidopsis thaliana Group VII ERF genes are low-oxygen and/or ethylen
 e regulated.  The manipulation of these ERFs can affect survival of low o
 xygen stress.  In rice (Oryza sativa)\, the Group VII ERFs SUB1A and SNOR
 KEL1/2 enable survival or escape of submergence\, respectively.  Recent f
 indings indicate that all five Group VII ERF family members of Arabidopsis
  thaliana are synthesized but unstable in air-grown plants. Low levels of 
 oxygen promote the accumulation of these transcription factors because the
 ir proteolysis requires oxygen. The presentation will describe the importa
 nce of energy management in flooding survival strategies and highlight our
  new appreciation of subtle but ecologically and agronomically relevant ge
 netic variation in the low oxygen sensing mechanism of plants.   4:00 pm
