 Title    Long-Term Effect of Diuron on Chlorophyllous Callus of Bromus erectus: Lipid Composition  
 Abstract    The selection o f plants resistant to photosynthetic herbicides is limited by the low rate o f success in obtaining a photosynthetic callus. An attempt was made to induce diuron tolerance with chlorophyllous tissue strains o f Bromus erectus: growth, chlorophyll contents and total fatty acids were studied during four months o f photoheterotrophic growth in the presence or absence o f 6 diuron. The presence o f the herbicide, which reduced the fresh weight by 40%, provoked increases in chlorophyll levels by 2-or 3-fold, and in galactolipids (especially D G D G) which were enriched in linolenic acid content. These results, closely related to already described characteristics o f herbicide-resistant material, suggest that callus o f Brom us erectus could constitute an interesting photosynthetic in vitro material.
