cyanobacterial dominance over competing green algae is identified. Evidence is provided on the molecular, chemical level that the iron chelator anachelin from the cyanobacterium Anabaena cylindrica promotes both the growth of cyanobacteria and reduces the growth of competing chlorophytes. These results illustrate a molecular strategy of addressing two challenges (nutrient availability and algal competition) by

铁螯合剂安达可林既促进了蓝细菌的生长,又促进了竞争性绿藻的生长。这些结果说明了通过一个分子解决两个挑战(营养物质可利用性和藻类竞争)的分子策略。在海洋和淡
