Chlorophyll a Fluorescence Predicts Total Photosynthetic Electron Flow to CO(2) or NO(3)/NO(2) under Transient Conditions.

abstract：:A culture of Chlorella established by 30-fold dilution of a culture already grown to a level of 15 ml packed cell volume per liter produces little chlorophyll for approximately 12 hours. Investigation of other characteristics such as nitrogen incorporation, increase in packed cell volume and dry weight as well as RNA ...

abstract：:The growth regulator abscisic acid (ABA) can be used to induce dormant bud structures (turions) in the duckweed Spirodela polyrrhiza L. In this paper we show that during this process, ABA rapidly induces elevated levels of mRNA transcripts encoding a novel basic peroxidase. In addition, we show that in the presence of...
