INTERNATIONAL REVIEW OF CYTOLOGY
The purpose of this chapter is to review the currently available information about
the megagametophyte, emphasizing work during the past two decades, and
particularly examining the female germ unit from four new perspectives: (1) the ...

The Encyclopedia of Seeds: Science, Technology and Uses
The nucellus is the multi-celled inner tissue within which the megagametophyte
develops. In some conifer seeds, this tissue becomes compressed during seed
development to form a papery covering (the nucellus membrane) outside the ...

Genomes of Plants and Animals
The megagametophyte in each mature seed is genetically equivalent to a
haploid progeny plant, thus any heterozygous locus in the seed parent will
segregate 1:1 in the megagametophytes, regardless of the pollen contribution.

J. Perry Gustafson, R.B. Flavell, 1996
Megagametophyte mapping populations were first used with allozyme markers to
estimate linkages among allozyme loci (Chapter 3; Guries et al., 1978, Rudin and
Ekberg, 1978, Conkle, 1981b, Adams and Joly, 1980). In the last 20 years, ...

The Evolutionary Biology of Plants
Sperm could gain access to the eggs of a megagametophyte by swimming
through the slit formed by the enfolding portions of the leaf lamina. Beneath this
slit, the megasporangium opened to expose the gametophyte and its egg within.

Paleobotany and the Evolution of Plants
As the megagametophyte enlarges, it causes the spore wall to rupture along the
triradiate suture. At the same time large numbers of archegonia undergo
development in the exposed tissues. Ten developing archegonia have been
counted in ...

Somatic Cell Genetics of Woody Plants
The megagametophyte reached its maximum length after the archegonia
matured. There were also other noticeable changes. The general appearance of
the megagametophyte when archegonia were first distinctly visible in whole or
bisected ...

Annual Plant Reviews, The Evolution of Plant Form
Although seasonal, some aspects of embryology, especially in Ginkgo, cycads
and conifers should be easy to study, in particular the free nuclear stages and
cellularization of megagametophyte development and embryogenesis. One of
the ...

Reproductive Versatility in the Grasses
occurred between all the cells of the Zea megagametophyte, but not in its outer
wall. Diboll & Larson (1966) described the mature megagametophyte wall of Zea
as a series of lamellae - the innermost is the wall of the functional megaspore, the
...
