Microspore Culture in Brassica
2003Pioneering research in Brassica microspore culture (1,2,3)rapidly led to the realization that microspores provide a powerful alternative to protoplast culture as a single-celled culture method in plants. These two single-celled systems are fundamentally different, both in tissue origin and in genetic variability.

Microspore culture of small grain cereals
Acta Physiologiae Plantarum, 2005Androgenesis of wheat, rice and triticale was studied in isolated microspore culture. It is the first publication which studies microspore culture reaction of Hungarian rice varieties. The effect of different basic media, lack and absence of growth regulators in culture media were tested on important parameters of microspore culture.

Triticale Isolated Microspore Culture for Doubled Haploid Production
2021Here, we describe a method of triticale isolated microspore culture for production of doubled haploid plants via androgenesis. We use this method routinely because it is highly efficient and works well on different triticale genotypes. To force microspores into becoming embryogenic, we apply a 21-day cold pretreatment.

Isolated Microspore Culture of Maize
1994The process of androgenesis is unique, in that haploid embryos arise from single gametophytic cells. Clear evidence for the unicellular origin of somatic embryos is lacking for most regeneration systems (Fransz and Schel 1991); therefore, totipotent microspores offer a potentially useful subject for both basic and applied studies.

Barley isolated microspore culture protocol
2003Among the cereals, barley (Hordeum vulgare L.) has been most successful in haploid production with many new cultivars produced. Most of these have come from wide hybridisation with H. bulbosum pollination. However, the potential for larger numbers from the culture of microspores is greater and successful procedures for isolated microspore culture of ...

Asparagus microspore and anther culture
2003Asparagus is a dioecious, perennial crop where male plants generally yield more than female plants. Consequently, an all-male hybrid can have improved productivity compared to one that is dioecious. Genotypes of males and females are Mm and mm, respectively, and all-male hybrids result from crossing females and supermales (MM).

Wheat microspore embryogenesis during in vitro anther culture
Theoretical and Applied Genetics, 1984Cytological analysis of microspore embryogenesis during in vitro culture reveals a high mortality in the first week and a latency phase of about one week before the first embryogénic mitosis. Genotypic differences observed during our wheat anther culture do not seem to originate at the induction level but are linked to the different abortion rates.

Anther culture and isolated microspore culture in timothy
2003Timothy (Phleum pratense L.) is one of the basic forage grasses in the world and the most important grass in winter snow covered northern latitudes. It is considered to be allohexaploid in nature (2n=6x=42). Timothy is valued for its winter hardiness, good palatability, and moderate feeding quality.

Journal of Structural Biology, 2005
To gain further insight into the role played by sporophytic anther tissues in the early stages of the androgenic process, we have compared the cytology and ultrastructure of barley embryogenic pollen grains obtained by anther culture with those obtained by isolated-microspore culture.

Microspore Culture for Haploid Plant Production
1995Haploid plants can be produced through in vitro culture of male gametophytic cells at the microspore or immature pollen developmental stage. These cells respond in vitro by undergoing embryogenesis or haploid callus proliferation. Plants can be regenerated through shoot and root induction in haploid callus and through culture of haploid embryos.
