Photosynthesis and the Emission of Isoprene Are Mediated by Respiration

  • 摘要: 将杨树叶片置于持续的光照下增加了其光合速率和异戊二烯的释放水平。持续的光照也诱导了总呼吸、细胞色素途径和交替呼吸途径容量的增加。用细胞色素途径和交替呼吸途径的抑制剂氰化钾和水杨基氧肟酸降低了光照下叶片的光合速率和异戊二烯的释放水平,也导致了光系统Ⅱ的光合效率和光化学淬灭系数的降低。这些结果表明了呼吸作用可能有助于光合作用的正常运行和光照下植物异戊二烯的释放。
    Abstract: After exposing fully expanded poplar (Populus alba L.) leaves to continuous irradiation,the photosynthetic rate and isoprene emissions increased.Continuous irradiation also enhanced the levels of total respiration and the capacities of the cytochrome and alternative respiratory pathways.Pretreatments with cytochrome and alternative respiratory pathways inhibitors,salicylhydroxamic acid and KCN,decreased the photosynthetic rate and isoprene emissions.These treatments also decreased the immediate quantum yield of PSⅡ electron transport and photochemical quenching.These results suggest that respiration plays a role in mediating photosynthesis and isoprene emissions.
