Transcriptional regulation of anther development in Arabidopsis.
Gene, 2019This review focuses on the current knowledge of transcription factors involved in Arabidopsis anther development. Anther development is a multistage process and controlled by a complex network of transcription factors acting in spatio/temporal manner ...

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.

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 ...

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.
