Cell Wall Composition and Structure Define the Developmental Fate of Embryogenic Microspores in Brassica napus

open access: yesFrontiers in Plant Science, 2021
Microspore cultures generate a heterogeneous population of embryogenic structures that can be grouped into highly embryogenic structures [exine-enclosed (EE) and loose bicellular structures (LBS)] and barely embryogenic structures [compact callus (CC ...

Cold-shock eliminates female nucleus in fertilized eggs to induce androgenesis in the loach (Misgurnus anguillicaudatus), a teleost fish

open access: yesBMC Biotechnology, 2011
Background Androgenesis (all-male inheritance) is generally induced by means of irradiating the eggs to inactivate the maternal genome, followed by fertilization with normal sperm.

Androgenesis and androdynamics in normal women

open access: yesCleveland 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 ...
