Oaks (Quercus spp.) are widely distributed trees of temperate regions, and are of major importance in forestry. Most species are used for wood production, although there are a few interesting peculiarities, such as cork production from the cork oak.

Microspore development in cultured maize anthers
Plant Cell Reports, 1988The present study follows in vivo and in vitro microspore development utilizing an anther culture-responsive maize genotype (Pa91×FR16) and a DNA-specific fluorescent dye (mithramycin). Cultured anthers were sampled at various times and scored for abnormal microspore divisions, multicellular masses, and embryo-like structures. The frequency of abnormal

Methodical improvements in rye anther culture
Plant Cell Reports, 1991The crucial problem in anther culture of rye (Secale cereale L.) is the very low regeneration capacity. Our study was conducted to overcome this restriction. The plant material used included a doubled haploid line (DH), two single crosses between DH Unes, and a tetraploid Secale cereale L. population.

The following procedure for large-scale production of doubled haploids (DH) in wheat at Svalof Weibull AB (SW) is based on protocols developed in Sven Bode Andersen’s laboratory in Copenhagen (Andersen et al., 1987; Tuvesson et al.,1989). Since then the tissue culture programmes were rationalised to a few steps in order to speed up DH production and ...

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 present long-term tissue culture programme aims at directing double haploid (DH) production of triticale towards responsive genotypes and at the same time allowing the practical use of anther culture in current breeding programmes. It is hoped that this can be achieved without limiting plant breeders to a few selected crosses.

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 ...

Haploids in higher plants have provided the subject of three symposia in recent years (36,78,106) and their use in plant breeding has been covered in a most comprehensive review (97). All four volumes explain in detail that haploids have the great advantage of providing a rapid, and in some species the only, route to complete homozygosity.

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,
