GENETIC ANALYSIS OF OVULE DEVELOPMENT
Annual Review of Plant Physiology and Plant Molecular Biology, 1998▪ Abstract Ovules are the direct precursors of seeds and thus play central roles in sexual plant reproduction and human nutrition. Extensive classical studies have elucidated the evolutionary trends and developmental processes responsible for the current wide variety of ovule morphologies.

Ovule and embryo development, apomixis and fertilization
Current Opinion in Plant Biology, 1998Genetic analyses, particularly in Arabidopsis, have led to the identification of mutants that define different steps of ovule ontogeny, pollen stigma interaction, pollen tube growth, and fertilization. Isolation of the genes defined by these mutations promises to lead to a molecular understanding of these processes.

The Ins and Outs of Ovule Development
2009In the past few years, ovule development has been widely studied in different plant species, both from a morphological and a more molecular point of view. At early stages of flower development, the placenta becomes specified inside the carpel and ovules develop from this tissue asmeristematic protuberances.

DEVELOPMENT AND COMPOSITION OF THE SPINACH OVULE
Acta Botanica Neerlandica, 1980SUMMARY The ultrastructure and histochemistry of the developing spinach ovule have been examined. The development and differentiation of the integuments, nucellus and female gametophyte results in an ortho-amphitropous organisation of the ovule. In the nucellus four parts can be distinguished: the conductive part, the original chalazal part, the ...

Ovule development in Arabidopsis: progress and challenge
Current Opinion in Plant Biology, 2011Female gametophyte, the central core of the ovule, is a simple seven-celled reproductive structure. Its stereotyped ontogeny provides a traceable model system to study mechanisms controlling cell growth, cell division, cell fate, pattern formation, and perhaps the function of essential genes in plants.

Molecular control of ovule development
Trends in Plant Science, 1996Enormous progress has been made over the past five years in understanding the floral homeotic genes, which specify the fate of the floral organ meristems. More recently, regulatory genes have been cloned from Petunia hybrida and Arabidopsis thaliana that play essential roles in the development of the ovule — the floral organ that contains the ...

Structure and Development of the Ovule in Bromeliaceae
Kew Bulletin, 2004Ovule structure and development are described for twelve species of Bromeliaceae, representing ten genera and all three subfamilies, including all three tribes of the polyphyletic subfamily Pitcairnioideae (Brocchinieae, Puyeae and Pitcairnieae). The characteristic micropylar and chalazal seed appendages of Bromeliaceae are compared with developing ...

Development of ovule and seed in Rapateaceae
Botanical Journal of the Linnean Society, 1988VENTURELLI, M. & BOUMAN, F., 1988. Development of ovule and seed in Rapateaceae. The structure of the ovules and/or seeds of twelve species of Rapateaceae were studied, some additional embryological characters also being recorded. The ovules are always anatropous, bitegmic and crassinucellate, but they differ in the shape, size and in thickness of the ...
