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.).

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]
The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

Strategies for the evolution of sex [PDF]
We find that the hypothesis made by Jan, Stauffer and Moseley [Theory in Biosc., 119, 166 (2000)] for the evolution of sex, namely a strategy devised to escape extinction due to too many deleterious mutations, is sufficient but not necessary for the ...

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 ...

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.

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 ...

Populations of doubled haploids for genetic mapping in hexaploid winter triticale. [PDF]
To create a framework for genetic dissection of hexaploid triticale, six populations of doubled haploid (DH) lines were developed from pairwise hybrids of high-yielding winter triticale cultivars. The six populations comprise between 97 and 231 genotyped

Popcorn (Zea mays L. var. Everta) haploids identified by Navajo phenotype and ploidy level
For popcorn, obtaining and identifying haploids are still challenging steps. We aimed to induce and screen haploids in popcorn using the Navajo phenotype, seedling vigor, and ploidy level.
