| Abstract: | In Anemia phyllitidis gametophytes two of the ethylene perception inhibitors (silver ions, Ag+; 2,5-norbornadiene, NBD) caused opposite effects on GA3-induced antheridia formation and on the increment of ACC (1-aminocyclopropane-1-carboxylic acid) content accompanying this process. Ag+ enhanced while NBD inhibited GA3-induced antheridiogenesis and each inhibitor modulated the level of ACC in a different manner. Cobalt ions (Co2+) and aminooxyacetic acid (AOA; the ethylene synthesis inhibitors), also modulated the level of GA3-induced ACC content differently. These results strongly confirm the earlier suggestion that ethylene plays a role of the second messenger in GA3-induced antheridiogenesis during “induction” and “expression” phases, and the 3rd h of the former phase is the time when elevation of ACC content induced while in the 6th h inhibited antheridiogenesis. Timing of changes in ACC content and morphogenetic effects of GA3-induced antheridiogenesis in A. phyllitidis gametophytes allowed to indicate that AOA together with NBD could participate in one while Co2+ and Ag+ in another ethylene synthesis and signaling pathway. |
