Microspore Culture for Haploid Plant Production

1995
Haploid 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.

Wheat microspore embryogenesis during in vitro anther culture

Theoretical and Applied Genetics, 1984
Cytological 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.

Brassica napus Rop GTPases and their expression in microspore cultures

Planta, 2006
Androgenesis in plants involves a shift in development that causes cultured microspore cells to form embryos rather than continue to develop pollen. In Brassica napus microspore culture a mild heat stress is used to switch on embryo development. An early hallmark of embryogenesis in this system is a symmetrical division of the nucleus instead of the ...

Microspore culture of Brassica species

2003
The production of haploid plants from isolated microspores of Brassica napus (L.) was first reported by Lichter in 1982 (Lichter, 1982). The embryo yields from these initial experiments were low but have since increased through manipulation of the culture technique.

Anther and microspore culture in Camellia japonica

1997
Haploid plants have the gametophytic chromosome number. They are of great importance for the production of homozygous plants and for mutation studies. The use of anther and microspore cultures for the induction of pollen embryogenesis hastens the production of haploids and gametoclonal variants.

Anther and microspore culture in Capsicum

1996
Pepper is an economically important vegetable and spice crop. Its high nutritional value, especially in vitamin A and C content, has increased fresh market demand for the sweet pepper (Capsicum annuum L.) in recent years. Capsicum frutescens L. remains valuable for the spice industry, especially in Spain, Hungary, and the United States. C.

Protocol for microspore culture in Brassica

2003
We have been using microspore culture of Brassica at the Institute of Horticulture and Crop Sciences, Agricultural University of Norway, since 1989, our focus has been on Brassica oleracea (cabbage), Brassica napus (swede) and Brassica rapa (chinese cabbage and summer turnip rapeseed). The protocol presented here is based on over 12 years of experience.

Protocol for broccoli microspore culture

2003
Broccoli (Brassica oleracea var. italica) is a vegetable cole crop of considerable interest to breeders and seed companies since its area of production has increased in recent years mainly due to improved nutritional qualities, e.g. anticancer properties. Breeding companies strive more and more to bring F1 hybrid seeds onto the market.

Barley isolated microspore culture protocol

2003
Among 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 ...
