IAA-induced apogamy in Platycerium coronarium (Koenig) Desv. gametophytes cultured in vitro
@article{Kwa1995IAAinducedAI, title={IAA-induced apogamy in Platycerium coronarium (Koenig) Desv. gametophytes cultured in vitro}, author={Siew-Hwa Kwa and Yeow Chin Wee and Tit Meng Lim and Prakash P. Kumar}, journal={Plant Cell Reports}, year={1995}, volume={14}, pages={598-602} }
Apogamous sporophytes were produced on Platycerium coronarium gametophytes cultured in the presence of indole-3-acetic acid (IAA). The percentage of apogamy as well as the total number of apogamous sporophytes produced per gametophyte clump were highest in the presence of 40 μM IAA. When ethylene was allowed to accumulate in the culture vessel in the presence of an optimum level of IAA, the percentage and total number of apogamous sporophyte production decreased significantly. Using light…

In Vitro Regeneration Systems of Platycerium
- Biology
- 2011
In this review, regeneration systems of Platycerium using in vitro techniques are summarized and compared to those among other fern species, and the influence of initial explants, culture media, plant growth regulators, wounding, etc., on morphogenesis, including apospory and apogamy is presented.
Exogenous and endogenous growth regulators on apogamy in Dryopteris affinis (Lowe) Fraser-Jenkins sp. affinis
- Biology, MedicinePlant Cell Reports
- 2005
The role of gibberellins on apogamy was supported by data showing a decrease in the percentage of gametophytes developing embryos because of the addition of flurprimidol to the culture medium.

Morphogenetic plasticity of callus reinitiated from cell suspension cultures of the fern Platycerium coronarium
- BiologyPlant Cell, Tissue and Organ Culture

The dark-green gametophytic callus showed a faster rate of growth and morphogenesis as compared to the pale-green sporophyticCallus, and the availability of cell cultures of the same ploidy level, but with two distinct pathways of development will be useful for comparative studies of developmental plasticity.

The first report of simultaneous production of calli and gametophytes from fern explants is reported, and it is reported that the calli regenerated sporophytes when cultured on MS medium without growth regulators and the gamettes grew vegetatively on MSmedium but produced sporophyte when transferred into 0.1 strength MS medium.
THE INFLUENCE OF CULTURAL CONDITIONS ON THE INDUCTION OF APOGAMY IN PTERIDIUM GAMETOPHYTES

Induced apogamy in plants with typical alternation of generations affords a rare opportunity to investigate and learn some of the conditions regulating the periodic expression of gametophytic and sporophytic phases.

Pteridium gametophytes cultured on a medium containing 4% sucrose under various qualities of light exhibit different developmental responses, allowing a distinct separation of the specific induction of apogamy from a general enhancement ofgametophytic growth.

It is concluded that GA content is a factor which may limit elongation in hypocotyls of sunflower, and that while exposure to ethylene results in reduced concentration of GA(1) this is not sufficient per se to account for the inhibition of elongation caused by ethylene.
Systematic inferences from spore and stomate size in the ferns

A considerable body of evidence has been assembled supporting the contention that spore size is related to ploidy level in the ferns and an exhaustive analysis of spore features of northeastern North American Isoetes provided new insight into spore-size variability.
