Abstract

The steady-state level of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphate 2-phosphatase (F6P2K/F26BPase) transcript has been found to be raised in the mangrove Bruguiera gymnorrhiza treated with 500 mM NaCl for 6 h. In the present study, we assayed both F6P2K/F26BPase activity and fructose-2,6-bisphosphate (F26BP) contents in leaves of salt- and water-stressed B. gymnorrhiza. In the plants treated with 500 mM NaCl, no increase in transcript level was observed after 1 day of treatment, while both the ratio between F6P2K and F26BPase activity (K/P ratio) and leaf F26BP level were about two-fold higher than in control plants.
