Induction of CO2 and Bicarbonate Transport in the Green Alga Chlorella ellipsoidea (I. Time Course of Induction of the Two Systems).

abstract：:We present a novel measurement setup for monitoring changes in leaf water status using nondestructive terahertz time-domain spectroscopy (THz-TDS). Previous studies on a variety of plants showed the principal applicability of THz-TDS. In such setups, decreasing leaf water content directly correlates with increasing TH...

Here we evaluate whether the effects on photosynthesis are large enough to cause changes in the relative composition of stable carbon isotopes, delta(13)C, of plant tissue samples, and, if so, how the changes ...
