Despite their complexity, each of C4 and CAM evolved numerous times independently in land plants. These origins were facilitated by the presence of enablers in some lineages of plants and the existence of evolutionary stable intermediates. Both C4 and CAM lineages diversified long after their initial...

evolution has reconfigured the functions of mesophyll and bundle-sheath cells such that CO2fixation by RuBisCO is repressed in the mesophyll and activated in the bundle sheath (Fig.1a). These species are known as C4plants because the pathway’s first step produces C4acids in mesophyll cells, whi...
研究未来全球变暖和氮沉降下C3、C4植物植硅体的变化规律,对松嫩草原优势群落演替方向的预判、古植被及古气候的重建和全球环境变化的预测等工作具有重要意义。本文选取松嫩草原的优势物种羊草(Leymuschinensis,C3)和芦苇(Phragmitescommunis,C4),对其进行模拟增温、施氮、CO2
This shows that the evolution of C4 photosynthesis strongly affects the differentiation of M and BS chloroplast proteomes, adapting each proteome to their specialized roles. To integrate the quantitative and qualitative data obtained in this study, we summarized several of our findings in Fig. 6. ...
At present, the major patterns in the ecology and evolution of C3and C4plants are attributed to the physiological differences between the C3and C4photosynthetic pathways. The foundation for this theory is the observation that the two pathways translate into distinct physiological advantages and disadvant...
they said. Roots from the East African mahogany tree and leaves from fem were found to exhibit potential anti-inflammatory effects. The results suggested that chimpanzees looked for and ate specific plants for their medicinal effects, ...
Scientists who study the evolution of language say wild chimpanzees have a more complex communication system than past research has shown. 研究语言进化的科学家说,野生黑猩猩的交流系统比过去的研究显示的更复杂。 The researchers say the animal...
