In clones of the red alga Laurencia obtusa, the frequency of vesicle transport from corps en cerise (CC) to the cell wall region was evaluated in response to differences in temperature, irradiance, desiccation, bacterial fouling, and bromine (Br) availability. In addition, the morphology of the corps en cerise was analyzed. Traffic of vesicles was induced by exposing L. obtusa to low temperatures and variations in irradiance. It was also verified that bacterial fouling induced vesicle traffic. Under high temperatures and desiccation, the membranous tubular connections were lost and transport of vesicles was not seen. The morphology of the corps en cerise varied according to the availability of Br in seawater. Exocytosis of secondary metabolites by L. obtusa was shown to vary in relation to temperature, irradiance, desiccation and bacterial fouling. The data suggest that the transport of vesicles in L. obtusa may be related to the inhibition of the microfouling community on the algal surface.
在红叶藻Laurencia obtusa 的克隆中，评估了从 corps en cerise (CC) 到细胞壁区域的囊泡运输频率对温度、光照、干燥、细菌污染和溴（Br）可用性的差异的响应。此外，还分析了 corps en cerise 的形态。通过将 L. obtusa 暴露于低温和光照变化来诱导囊泡运输。还验证了细菌污染会诱导囊泡运输。在高温和干燥下，膜状管状连接丢失，并且看不到囊泡的运输。 corps en cerise 的形态根据海水中 Br 的可用性而变化。通过 L. obtusa 的次级代谢物的胞吐作用与温度、光照、干燥和细菌污染有关。数据表明，L. obtusa 中的囊泡运输可能与抑制藻类表面的微污染群落有关。
