Anther culture of papaya (Carica papaya L.)
Plant Cell Reports, 1985Papaya (Carica papaya L.) anther containing microspores in tetrad to early-binucleate stages were successfully cultured on 1/2 strength MS salts and vitamins with full strength Na-Fe-EDTA supplemented with 2 mg/l NAA, 1 mg/l BA and 6% sucrose for callus initiation and formation.

It is becoming increasingly evident that endogenous ethylene can have large and diverse effects on growth and development in a wide range of plant tissue culture systems [2]. Anther culture in which haploid plants are regenerated from immature microspores is important because it allows the rapid production of homozygous lines for breeding and genetic ...

The maize pollen grain represents the beginning of a short-lived gametophytic phase during which the two sperm are delivered to the embryo sac prior to fertilization. Although this stage of the life cycle normally consists of only a few cell divisions, under certain experimental conditions, gametophytes can be induced to undergo an altered development,

Anther culture of Solanum genotypes
Plant Cell, Tissue and Organ Culture, 1987Anther culture response was examined in five Solanum genotypes. Large genotypic differences exist in response to culture and liquid culture media were found to be superior to agar solidified media systems. Pre-treatment effects on embryoid induction were also investigated and two of the genotypes displayed differential response to temperature stress ...

Anther Culture of Chickpea (Cicer arietinum L.)
2021Doubled haploid technology allows for producing completely homozygous plants in one generation, which is a very efficient and fast method compared to the production of near-homozygous lines by selfing through conventional breeding methods. However, grain legumes are known to be recalcitrant for most of the in vitro approaches to doubled haploidy.

Callus tissues and green globular embryoids are obtained in a pea anther culture on a medium with 2,4-D after cold (4°C) treatment of buds. In experiments with the use of treating buds with cold (4°C) and anther culture with heat (32 and 35°C), green embryogenic and morphogenetic calli are induced and regenerant plants are obtained.

In this chapter, the published reports of anther and microspore culture of Petunia will be reviewed in comparison with culture of related Solanaceous genera. The reasons for the type and frequency of microspore development in Petunia will be explored.

Anther cultures of Nicotiana tabacum L. mutants
Theoretical and Applied Genetics, 1976The theoretically expected and experimentally observed phenotypic ratios have been compared in populations of haploids derived from chlorophyll mutants of Nicotiana tabacum L. with a known genotypic constitution. The frequencies of mutant genotypes were significantly lower than the expected values, proving the existence of selection in a system of ...

Protocol for rye anther culture
2003Rye (Secale cereale L.) is a cross-pollinated cereal, which has a strong self-incompatibility system. Population varieties of rye are highly heterozygous. Genes for self-fertility can, however, be introduced from wild relatives for purposes of hybrid rye breeding.
