Large-scale green tides in the Yellow Sea occurred for 13 consecutive years since 2007.The unusual co-occurrence of green tides and golden tides occurred in the Yellow Sea in 2017.The causative species are Ulva prolifera and/or Sargassum horneri.Previous studies on physiological response characteristics of U.prolifera and S.horneri are done in the laboratory mainly,and there is no in-situ comparative study in this regard.In this study,the in-situ physiological response characteristics of both species were measured.The results indicated that cyclic electron flow and antioxidant system play more important roles in protecting U.prolifera,while non-photochemical quenching is more important for adapting to the environment in S.horneri.U.prolifera has a stronger ability to utilize nutrients to rapidly increase its biomass under a suitable condition compared to S.horneri.

假单胞菌属在各种环境广泛分布且具有重要的生态应用价值,然而当前研究对其环境适应性遗传基础的解析尚不充分.选择33株有效发表且具有全基因组序列以及一株新分离的假单胞菌的全基因组进行泛基因组学分析.结果表明,选择的假单胞菌属菌株泛基因组含有173 271条蛋白序列,共有30 847个同源基因家族,包括1 505个核心基因,基因组呈开放型.通过分析不同基因组的基因组演化特征,发现通过基因水平转移获得的基因占整个基因组的比例为32％-48％,其平均基因岛数量为53个.发现假单胞菌属泛基因组的开发性与其频繁的基因水
