ABA enhances gametogenesis and increases game tolerance to
salinity
Once N depletion was initiated, all cultures continued to grow for 24,
After that the growth, based on OD values, of N‐depleted control and
mock cells slowed till the end of the experiment, suggesting complete
cessation of net cell division (Fig. 6). However, the rate of gamete
formation in the ABA-treated C. reinhardtii cultures increased
more than 2-fold (OD750 = 0.86) of that in the control
cultures (OD750 = 0.39) after 48 h of induction under
normal conditions, before they declined after 72 h.
In comparison, the rate of gamete formation was lower in all cultures
under salt stress, with 24 h extended survival time in ABA-treated cells
(Fig. 7).
