Microspore Derived Embryogenesis
1992The period of cellular development that encompasses meiosis and microsporogenesis is of key scientific and commercial interest, but the complex cytological organisation of the anther and the rapid pace of differentiation has made it difficult to investigate by standard molecular methodology.

Mechanisms of Microspore Embryogenesis
1992As Haldane stated in 1937 “Every species is at the mercy of its pollen grains”, and although this motto is undoubtedly true in evolutionary terms, it is only relatively recently that we have been able to disrupt at will this critical phase of plant development.

Induction of embryogenesis in isolated microspores of tulip
Plant Science, 1994Abstract Isolated microspores of tulip ( Tulipa gesneriana ) cultivars ‘Leen van der Mark’ and ‘Rosario’ could be induced to form embryos. Microspores of a young developmental stage, i.e. early and mid unicellular, were the most responsive. The first sporophytic divisions, resulting in microspores with three or four vegetative-like nuclei were ...

Evidence for microspore embryogenesis in wheat anther culture
In Vitro Cellular & Developmental Biology - Plant, 1991In wheat, plants may be regenerated from microspores via direct embryogenesis or organogenesis or embryogenesis from callus. Light and scanning electron microscopy were used to carefully study morphogenesis of microspore-derived plants from anther culture on modified 85D12 starch medium and to determine whether the plants were formed via organogenesis ...

Influence of ethylene in microspore embryogenesis
1996Ethylene (C2H4) is the simplest olefin and exists in the gaseous state under normal physiological conditions; it regulates many aspects of plant growth, development and senescence and its effects are commercially important (Yang and Hoffman, 1984). Some of the physiological processes influenced by ethylene are release of seed, bud dormancy, seedling ...

Microspore embryogenesis inCitrusand other fruit crops
Acta Horticulturae, 2017Conventional methods, involving several generations of selfing, are not applicable to produce homozygous lines in Citrus as well as in the other fruit crops, due to the high heterozygosity of the genomes, the long duration of the generation cycle, the large size, and, often, the self-incompatibility. For this reason, there is no different way to obtain
