Effects of Low CO2 on Photosynthetic Characteristics of Ottelia alismoides and Hydrilla verticillata
|
Abstract:
Photosynthetic characteristics of Ottelia alismoides and Hydrilla verticillata were studied after the two species were incubated under low CO2 conditions.The PEPC/Rubisco ratio of O.alismoides increased from 0.45 to 4.17 and of H.verticillata increased from 0.47 to 4.17 after low CO2 induction.The activity of PEPC and NAD-ME increased more than 10-fold and other C4 enzymes such as NAD-MDH and PPDK also increased significantly after low CO2 induction.Other photosynthetic characteristics also changed signific...
