Apogamic induction of haploid plasmodia in a myxomycete, Didymium iridis
Developmental Biology, 1976Abstract Interisolate crosses between haploid (mean DNA = 0.32) CR 5-5 ( A 2 ) myxamoebae and polyploid (mean DNA = 1.80) CR 2–25 ( A 5 ) myxamoebae of the myxomycete Didymium iridis result in plasmodia that have the haploid (mean DNA = 0.32) DNA content rather than the predicted polyploid value.

Early spontaneous diploidization of maternal maize haploids generated by in vivo haploid induction
Euphytica, 2014The production of doubled haploid (DH) lines has become a key technology in maize (Zea mays L.) research and breeding. However, most of the haploid plants are sterile and in many cases artificial chromosome doubling involves the use of costly and toxic chemicals.

Haploid induction in onion via gynogenesis
2003Onion (Allium cepa L.) is a biennial monocotyledoneus plant belonging to the Alliaceae family. Within the Allium species onion is the most economically important with a total world acreage of 2,7 million ha dry onions and production of over 46 million ton in 2001 (FAO, 2001).The demand for specific varieties adapted to local agroclimatic conditions is ...

Induction of Haploid Androgenesis in Pacific Oyster by UV Irradiation
Marine Biotechnology, 2004Androgenesis, development from paternal but not maternal chromosomes, can be induced in some organisms including fish, but has not been induced previously in mollusk. In this study we investigated the induction of haploid androgenesis in the Pacific oyster by ultraviolet irradiation and observed nuclear behavior in the androgenetic eggs.

Improved Procedure for Induction of the Androgenetic Doubled Haploids in Zebrafish
Zebrafish, 2018Androgenesis is useful for induction of doubled haploids from male genetic resources and contributes to the restoration of individuals from cryopreserved sperm. Here, we determined the suitable conditions for egg in vitro preservation and the suitable dose of UV irradiation for genetic inactivation of the egg nucleus, and established an improved ...

Increased induction and chromosome doubling of androgenetic haploid rye
Theoretical and Applied Genetics, 1977Further progress of studies aimed at increasing production of androgenetic Secale cereale plants via the culture of anthers is described. Two culture media initially developed for rice and wheat anther culture have been shown to have pronounced influence on rye. It has been possible to increase the average percentages of responsive anthers (i.e.

Cyto-swapping in maize by haploid induction with a cenh3 mutant
Nature PlantsMaize mutants of the centromeric histone H3 (CENP-A/CENH3) gene can form haploids that inherit only chromosomes of the pollinating parent but the cytoplasm from the female parent. We developed CENH3 haploid inducers carrying a dominant anthocyanin colour marker for efficient haploid identification and harbouring cytoplasmic male sterile cytoplasm, a ...

Advances and Challenges in Haploid Induction for Warm-Season Legumes
Journal of Agricultural and Food ChemistryHaploid induction via doubled haploid (DH) technology is pivotal for achieving true homozygosity in plant breeding; however, Fabaceae species lag in establishing effective haploidization methods. This review explores recent advances in DH techniques for warm-season legumes, including soybean, cowpea, pigeon pea, common bean, peanut, mung bean, and ...
