The promoter activity of a 2.2-kb DNA fragment from the 5' flanking sequence of the tap1 gene of snapdragon has been characterised in tobacco with the β-glucuronidase reporter gene. The tap1 promoter conferred to the reporter gene an expression that was limited to the early stages of anther development.

Pollen Dimorphism and the Frequency of Inductive Anthers in Anther Culture of Triticum monococcum
Biochemie und Physiologie der Pflanzen, 1982Summary The frequenry of in vitro cultured Triticum monococcum anthers showing multicellular pollen development was with the exception of one instance significantly lower than the estimated frequency of anthers exhibiting pollen dimorphism at anthesis.

Abstract Anthers of 2 tetraploid Rosa species (4 n =28) were plated on selected basis media, supplemented with various amounts of auxins and kinetin, at different bud stages and using various light conditions. Among the media tested, MS medium with 2.0 mg/l IAA and 0.4 mg/l K was generally the best for anther culture of R.

Pre-meiotic anther development
2019Most genetic and molecular analyses of anther development utilize Arabidopsis thaliana, Oryza sativa (rice), and Zea mays (maize). Especially in maize, early stages of anther development are easy to study because: (1) Maize has unisex flowers. (2) Compared to rice or A.

Anther Carotenoids and the Synthesis of Sporopollenin
Nature, 1968SHAW et al.1–3 are at present carrying out valuable new work on the chemistry of resistant spore wall materials of the general class of sporopollenins following the pioneer studies of Zetzsche's group in the 1930s4. Shaw and Yeadon1,2 have concluded, from observations on the pollen of Pinus sylvestris and Lycopodium clavatum, that sporopollenin ...

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.

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.

The production of doubled haploids through androgenesis represents a modern tool for the improvement of cultivated species enabling plant breeders to produce homozygous lines in a few months. In barley and other cereals, the use of androgenesis has generated a number of cultivars currently available and cultivated in many countries.
