DESCRIPTION:Dr Muriel Raveton\, LECA-Pollution\, Environnement\, Ecotoxico
 logie\, Ecoremédiation (P3E)\, Université Joseph Fourier\, Grenoble\, Fr
 ance\nOrganochlorines (OCs) are known to be persistent organic pollutants 
 due to their high lipophilicity and stability. Therefore\, solutions to re
 store polluted system by bio-technologies are studied especially using pla
 nt materials. For this purpose\, phytoextraction of standard OCs\, lindane
 \, was experimented. Screening of plant species adapted to OCs exposition 
 (biomass and morphological criteria) permitted to select Zea mays as a rel
 atively tolerant plant. Therefore\, 7-day-old plants were exposed to a con
 centration range of lindane (0.07 – 7 mg/l) and chlordecone (0.008-1 mg/
 l) to determine toxicity featuring. Using biomass\, oxidative stress\, apo
 ptosis\, cell death indicators and cell cycle regulators\, the OCs effects
  on root tissues were characterized. Root cell viability was strongly depe
 ndent on the OCs concentrations: apoptosis and cell death exponentially in
 creased with OCs concentrations. However\, some differences in cell cycle 
 regulation were noted comparing roots exposed to lindane and chlordecone.
