... "microspore embryogenesis" [refers] to the in vitro culture of the immature male gametophyte... The haploid embryos... can be germinated and grown into mature plants, but these plants are sterile due to their inability to produce gametes with a balanced chromosome number after meiosis. Chromosome doubling, which occurs either spontaneously in culture or after the application of... agents such as colchicine, restores the ploidy level and fertility of the derived plant...  3, record 1, English, - microspore%20embryogenesis

Le mode de reproduction sexuée du nori [du genre Porphyra] implique l'alternance de deux générations : une phase haploïde macroscopique (le gamétophyte, annuel) qui est la fronde foliacée et une phase diploïde microscopique (le sporophyte) appelée conchocelis. Ce dernier a la forme d'un filament qui, à maturité, émet des conchosphores qui se développent à leur tour en une nouvelle fronde (gamétophyte).  1, record 3, French, - conchocelis
