Ethylene is a positive regulator for GA3-induced male sex in Anemia phyllitidis gametophytes.

A Kaźmierczak1.   

Abstract

Effects of the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) on the development and expression of male sex were tested using the model of the three-zonal structure of 12-day-old (15-celled) Anemia phyllitidis gametophyte. ACC at 10 microM concentration enhanced the number of antheridia induced by gibberellic acid. Cytomorphological measurements showed that this effect was limited to only the antheridial region of gametophytes and depended on transverse expansion of antheridial mother cells. Time-course cytophotometrical measurements showed that this promotive effect of ACC was preceded by reorganization of nuclear chromatin and induction of DNA synthesis in nuclei in the antheridial region cells of fern gametophytes.
