Production of embryos from microspore cultures of Portuguese tronchuda cabbage landraces [PDF]
, 1996 Twelve accessions of tronchuda cabbage landraces were tested for their ability to produce embryos through microspore culture in NLN-13 medium. A sample from all the isolations was stained with DAPI for determination of microspore developmental stage. The

Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Obtaining calli and regenerated plants in anther cultures of pea
Czech Journal of Genetics and Plant Breeding, 2014 Pea (Pisum sativum L.) is a species for which there is no efficient method for the recovery of haploid plants yet. This research investigated the influence of various genotypes, nutrient media, and stress treatments on callus formation, embryogenesis and

Morphogenic microspore as an initial cell of androgenesis in vitro: review of the problem [PDF]
, 2017 The phenomenon of androgenesis in vitro is widely used in biotechnological investigations of commercially valuable plants. When solving the specific tasks it is important to enter into the culture in vitro anthers containing sporogenous cells which are ...

Chromatin differentiations in microspores
Experientia, 1971 2 p.-1 fig. En núcleos de microsporas deAllium cepa se describen estructuras de 1 µm de diámetro, de baja densidad y estrechamente relacionadas con varias masas de cromatina, las que se equiparan con los denominados «micropuff» recientemente descritos.
