芙蓉是一个红树林伴生植物，分布于潮间带湿地（L种群）和内陆（T种群）的不同环境。因此，它是一种理想的生态适应性和耐盐性研究的植物。在这项研究中，我们比较了两个群体的反应，结合全球转录分析和生理分析的盐度。微阵列转录谱分析表明，共享和分歧的反应，在两个人口的盐度胁迫。在两个群体中，共鉴定出575个单基因为盐响应基因。共同的反应体现在限制核糖体功能，光合作用和细胞代谢的调控基因。一组基因功能的细胞运输和细胞解毒和一个关键的转录因子AP2结构域的蛋白参与环境响应，在两个群体中的不同表达。生理分析表明，L群体的光合作用对盐胁迫的敏感性低于T群体，且具有较强的K+：Na+调节能力。基因芯片和生理数据均表明，L种群在高盐度下具有较高的适应性，这可能与其对原生环境的长期适应有关。
Hibiscus tiliaceus L. is a mangrove associate that occupies the divergent environments of intertidal wetland (L population) and inland (T population). Thus, it is an ideal plant for the study of ecological adaptation and salt tolerance. In this study we compared responses of the two populations to salinity combining a global transcriptional analysis and physiological analysis. Microarray transcript profiling analysis showed both shared and divergent responses to salinity stress in the two populations. A total of 575 unigenes were identified as being salt-responsive in the two populations. Shared responses were exemplified by the regulated genes functioning in confining ribosomal functions, photosynthesis and cellular metabolism. A set of genes functioning in cellular transporting and cell detoxification and a crucial transcription factor AP2 domain-containing protein involved in environmental responsiveness, were differently expressed in the two populations. Physiological analysis showed that the L population was less susceptible to salt stress in photosynthesis and had a stronger capability of K+ : Na+ regulation than the T population. Both microarray and physiological data showed the L population possess higher fitness under high salinity, probably due to it its long-term adaptation to their native environment.
