    Submerged environment and terrestrial environment have huge differences in light, water availability, and the form and concentration of inorganic carbon


    Wuhan Botanical Garden, Chinese Academy of Sciences aquatic biology Research Group research team selected Potamogetonaceae bamboo leaf pondweed ( Potamogeton wrightii ) as research material for the anatomical structure of the aquatic plants, photosynthetic physiological response, the use of transcriptome sequencing technology, further Comprehensively elucidated the adaptation mechanism of P.


     In addition to adapting to low light, more than 50% of submerged plants have evolved the ability to use HCO 3 - as a backup inorganic carbon source to cope with the lack of CO 2 in


     Research paper points respectively to "BiologicalAdaptive Mechanisms displayed by A Freshwater Plant to Live in Aquatic and Terrestrial Environments" and " Bicarbonate-use by Aquatic macrophytes android.


     

    Different Submerged Plants HCO 3 - using the mechanism will be external environment


    When submerged plants use HCO 3 - as an inorganic carbon source, it will significantly affect the pH of the


     More than 20 submerged plants that can utilize HCO 3 - but do not produce leaf polarization and cannot utilize HCO 3 - have carried out acute toxicological experiments of ammonium
