Maize has for many decades been both one of the most important crops worldwide and one
of the primary genetic model organisms. More recently, maize breeding has been impacted …

Embryogenesis in plants is a unique process in the sense that it can be initiated from a wide
range of cells other than the zygote. Upon stress, microspores or young pollen grains can be …

Under stress, isolated microspores are reprogrammed in vitro towards embryogenesis,
producing doubled haploid plants that are useful biotechnological tools in plant breeding as …

In the early 1990s, many basic protocols were developed for haploidy and doubled
haploidy, but most were inefficient. During the last decade, progress in technology has been …

Doubled haploid plants are invaluable breeding tools but many crop species are recalcitrant
to available haploid induction techniques. To test if haploid inducer lines can be engineered …

The developmental plasticity of plants is beautifully illustrated by the competence of the
immature male gametophyte to change its developmental fate from pollen to embryo …

The microspore is at the centre of a variety of topics in modern plant science and breeding.
Isolated microspore cultures have the remarkable quality of resembling the alternation of …

The formation of reactive oxygen species induced by aluminium stress was investigated in
an Al-sensitive wheat (Triticum aestivum L.) genotype and in Al-tolerant lines developed by …

Androgenesis has become the most frequently chosen method of doubled haploid (DH)
production in major crops. Theoretically, plantlets derived from in vitro cultured microspore …

This paper describes an efficient colchicine-mediated technique for the in vitro induction of
hop tetraploids and its confirmation by flow cytometry. A window of conditions generated a …
