Ovule and megagametophyte development in orchids
1997Sexual reproduction is essential for the long-term survival of plant species. The process of meiosis allows for random assortment of parental genes which enable the offspring to adapt better to environmental changes (Pennell, 1988). In order to understand reproductive processes in plants, information concerning ovule development is indispensable.

DEVELOPMENT OF OVULE AND SEED IN MARANTACEAE
Acta Botanica Neerlandica, 1983SUMMARY The development of ovule, seed and seed coat in a few representatives of the Marantaceae was studied. A subdermally initiated outer integument was found in a monocotyledon for the first time. The seed, which belongs to the most complex among the monocotyledons, is campylotropous and, furthermore, characterised by a so-called perisperm ...

Development and evolution of the unique ovules of flowering plants
2019Ovules are the precursors to seeds and as such are critical to plant propagation and food production. Mutant studies have led to the identification of numerous genes regulating ovule development. Genes encoding transcription factors have been shown to direct ovule spacing, ovule identity and integument formation.

Ovulation, fertilization and pronucleus development in superovulated gilts
Theriogenology, 1994Estrus was synchronized in 45 gilts by ingestion of Zinc-Methallibur in the feed for 15 d. On Day 16 each gilts was treated with PMSG (1200 IU i.m.) followed in 72 h by hCG (500 IU i.m.). Gilts were inseminated 24 and 36 h after the onset of estrus followed by slaughter of groups (n = 4 or 5) at 40 h, 44 h, 48 h, 52 h, 56 h, 60 h and 64 h after hCG ...

Microscopic Analysis of Ovule Development in Arabidopsis thaliana
2012Ovules are the major female reproductive organs in higher plants. In addition, ovules of Arabidopsis thaliana are successfully used as model system to study plant organogenesis. Here we describe two microscopic techniques to analyze Arabidopsis ovule development from the organ to the cellular level in a rapid and reproducible fashion.

Development of ovarian follicles in readily ovulating patients during ovulation induction
1984The growth of the human ovarian follicle both in natural and stimulated cycles has been studied in great detail by such illustrious scientists as Hackerloer1, Quenan2, O’Herlihy3 and Ylostalo4.
