Fine structure of plastids during androgenesis in Hordeum vulgare L.
Acta Societatis Botanicorum Poloniae, 2014 The fine structure of plastids was studied in the course of androgenesis in in the pollen of Hordeum vulgare L. It was found that these organelles occur in all stages of androgenesis.

In-vitro Androgenesis in Rice: Advantages, Constraints and Future Prospects
Rice Science, 2016 In vitro androgenesis is an important component of plant biotechnology when the pollen grains are forced to switch from their normal pollen developmental pathway towards an embryogenic route. Haploid and doubled haploid produced through androgenesis have

Androgenesis and androdynamics in normal women
Cleveland Clinic Journal of Medicine, 1990 The effects of estrogenic steroid hormones in women are apparent, but the circulating androgen levels are much higher. Compared with serum estrone and estradiol levels, circulating testosterone levels are five to 10 times higher, androstenedione levels 30 times higher, dehydroepiandrosterone levels 100 times higher, and dehydroepiandrosterone sulfate ...

History and Current Status of Haploidization in Carrot (Daucus carota L.)
Agronomy, 2023 The induction of haploid cell development into normal plants enables the production of doubled haploid lines, which are homozygous and can be used in breeding programs as an alternative to conventionally derived inbred lines.
