GA3 content in young and mature antheridia of Chara tomentosa estimated by capillary electrophoresis
Folia Histochem Cytobiol 2005;43(1):65-67.
Abstract
The content of gibberellic acid (GA3) in male sex organs of Chara tomentosa L. was estimated using capillary
electrophoresis. Young antheridia contained 0.25 μg GA3 while mature ones 0.48 μg per antheridium. Although there are
significant differences in GA3 content in antheridia between C. vulgaris and C. tomentosa, these values calculated per one
spermatid are 2.4 and 3.3 pg, respectively. The present results compiled with the previous knowledge about regulation of
GA3-dependent development of Characeae species allow an implication that the mechanisms controlling antheridia differentiation
in both species can be similar
