The fluorescent proble Acridine Orange has provided valuable information about changes in levels of insoluble RNA during meiosis in pollen mother cells of Taxus baccata, in which prophase is unusually prolonged. By combining the data offered by fluor

The central theme of Green Plants, first published in 2000, is the astonishing diversity of forms found in the plant kingdom, from the simplicity of prokaryotic algae to the myriad complexities of flowering plants. The book is arranged according to g

It is argued that the phasic alternation of sporophyte and gametophyte in ferns involves changing gene activation during oogenesis and sporogenesis respectively. The reasons for the change in activation are to be sought in the nutritional states of t

The recognition of apoptosis (programmed cell death) as an accompaniment of normal development, the products released by the protoplasts undergoing self-destruction being utilized by adjacent living cells, stimulates renewed interest in Haberlandt's

A remarkable feature of megasporogenesis, as seen in the heterosporous fern Marsilea and almost all seed plants, is the regular death of three of the products of meiosis. A general cause of this phenomenon has been hard to identify. Theories invoking

Angiosperms differ in their ability to fertilize themselves. Differ? ences in self-compatibility (SC) presumably reflect ancient events because both self-compatible and self-incompatible plants occur throughout the angiosperms. It has often been assu

Although apospory and apogamy are commonly regarded as aberrations, it is conceivable that they were frequent phenomena in ancient floras. In living plants apospory and apogamy offer the opportunity to investigate the factors causing change of reprod
