The origin of multicellular life from unicellular beings is an epochal step in the evolution of eukaryotes. There are several factors influencing cell fate choices during differentiation and morphogenesis of an organism. Genetic make-up of two cells that

Triticale haploidy in vitro (literature review)
Triticale (× Triticosecale Wittmack) is a hybridized grain crop developed from wheat and rye crossings. Today, triticale is a multipurpose commercial grain crop with great potential as a human food and animal feed.

Microspore embryogenesis in vitro: the role of stresses
Gametic embryogenesis is one form of totipotency of plant cells, in which either male or female gametes are induced to form embryoids (sporophytes). Regeneration of haploid plants from embryoids and subsequent chromosome duplication result in doubled ...

Comparison of methods for obtaining doubled haploids of carrot
Doubled haploid lines of carrot can be obtained through androgenesis in anther cultures and in isolated microspore cultures. The two methods were compared using three carrot cultivars (‘Kazan F1’, ‘Feria F1’, and ‘Narbonne F1’) at the androgenesis ...

History and Current Status of Haploidization in Carrot (Daucus carota L.)
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.

Efficiency of anther culture technique in the production of wheat double haploids [PDF]
The objective of the study was to investigate efficiency of anther culture in the production of spontaneous double haploids from randomly selected heterozygous genotypes of wheat (Triticum aestivum L.).

Diploidization of cucumber (Cucumis sativus L.) haploids by colchicine treatment
Haploid cucumber plants are totally infertile and do not undergo spontaneous diploidization. The use of haploids depends on the possibility of doubling the chromosome number and the obtaining of stable doubled haploids (DH).

Determination of the level of androgenesis in tobacco (Nicotiana tabacum L.) [PDF]
Androgenesis is the newest and most secure method to obtain haploid plants in vitro, where vegetative or generative nucleus of a pollen grain is stimulated to develop into a haploid individual.

The Roads to Haploid Embryogenesis
Although zygotic embryogenesis is usually studied in the field of seed biology, great attention has been paid to the methods used to generate haploid embryos due to their applications in crop breeding. These mainly include two methods for haploid embryogenesis: in vitro microspore embryogenesis and in vivo haploid embryogenesis.
