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 ...

Proteomics in Rapeseed Microspore Embryogenesis
2008This chapter reviews the proteomics research performed to elucidate the molecular processes associated with embryo initiation and development in Brassica napus (rapeseed) microspore-derived embryo cultures. Classical biochemical methods such as combined [35S]-methionine labelling and 2-D gel electrophoresis (2-DE) have been used for the large-scale ...

Microspore Embryogenesis in Almond (Prunus dulcis Mill.)
2018Almond is the most important tree nut crop in terms of commercial production. Its production is limited to areas characterized by a Mediterranean climate, including regions in the Mediterranean countries, the Central Valley of California, Central Asia, the Himalayan slopes and some equivalent areas in the Southern Hemisphere, including Argentina ...

Wheat microspore embryogenesis during in vitro anther culture
Theoretical and Applied Genetics, 1984Cytological analysis of microspore embryogenesis during in vitro culture reveals a high mortality in the first week and a latency phase of about one week before the first embryogénic mitosis. Genotypic differences observed during our wheat anther culture do not seem to originate at the induction level but are linked to the different abortion rates.

REGULATION OF THE INDUCTIVE PHASE OF MICROSPORE EMBRYOGENESIS IN BRASSICA NAPUS
Acta Horticulturae, 1996In cultured microspores from Brassica napus, embryogenesis can be synchronously and irreversibly induced by elevating the culture temperature to 32°C for a minimum of 8 h. Culture at 18°C allows gametophytic development to continue, and results in the formation of pollen in vitro.

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.

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.

Scanning electron microscopy of microspore embryogenesis inBrassica spp.
Plant Cell Reports, 1997Scanning electron microscopy was employed to study and compare microspore embryogenesis in vitro with pollen development in planta inBrassica napus andB. oleracea. An exine with its specific pattern had already been formed, when microspores were released from tetrads.

Programmed Cell Death and Microspore Embryogenesis
2008Programmed cell death (PCD) occurs in the anther during in vivo micro-spore/pollen development. The first hallmarks are detected in the tapetum at meiosis and consist in progressive degeneration of organelles such as mitochondria, as well as DNA degradation into multiple of 180 kpb fragments.
