Studies on the role of gibberellins in the regulation of spermatogenesis in Chara vulgaris L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
Antheridia from isolated nodes of Chara vulgaris, developing in the presence of either AMO-1618 or GA3, were studied. AMO-1618 which lowers the level of endogenous gibberellins causes a significant, proportional to the concentration, reduction in: 1) the

Influence of the light factor on the course of the cell cycle in the successive generations of the antheridial filaments of Chara vulgaris L.

open access: yesActa Societatis Botanicorum Poloniae, 2015
The exposure to continuous light causes a rise of the mitotic index in the successive generations of the antheridial filaments of Chara vulgaris, whereas culture in darkness leads to a considerable depression of mitosis, and if prolonged, to its complete

PCC-like induction of mitosis in Chara vulgaris antheridia initiating differentiation of spermatozoids in the darkness

open access: yesActa Societatis Botanicorum Poloniae, 2014
The objects of this research were the antheridial filament cells of Chara vulgaris which after 5-day mitodepressing treatment of the darkness reactivated mitosis (without light stimulation) in the result of the physiological state evocing the initiation ...

Chara — a living sister to the land plants with pivotal enzymic toolkit for mannan and xylan remodelling [PDF]

open access: yesPhysiologia Plantarum., 2023
Land-plant transglycosylases ‘cut-and-paste’ cell-wall polysaccharides by endo-transglycosylation (transglycanases) and exo-transglycosylation (transglycosidases). Such enzymes may remodel the wall, adjusting extensibility and adhesion.
