The synergid has thick wall at the micropylar region and gradually thins towards
chalazal portion. Sometimes the chalazal portion lacks the wall, but instead has
two plasma membranes. Synergid has hooks at the micropylar region (fig-5.3 B).

Molecular Embryology of Flowering Plants
Based on examination of a limited number of species, indeed it appears that
synergid degeneration is a preprogrammed, nonrandom event. In Helianthus
annuus, the synergids are iso- morphic; however, one is found closer to the
placenta ...

INTERNATIONAL REVIEW OF CYTOLOGY
In Arabidopsis (Mansfield et al., 1991) plasmodesmata are not observed between
the synergid and central cells, although synergid-to-synergid plasmodesmata are
frequently observed in Arabidopsis, Gossypium (Jensen, 1965a), and in ...

Biocommunication of Plants
The two female gametophytic synergid cells have been shown to play a central
role in attracting the pollen tube over the last distance to the micropyle in the
ovule and facilitating fertilization (Dresselhaus 2006; Marton and Dresselhaus
2010).

Annual Plant Reviews, Fruit Development and Seed Dispersal
The filiform apparatus is an elaborated cell wall present at the synergid
micropylar pole that likely plays a role in pollen tube guidance and reception (
Kasahara et al., 2005). Punwani et al. (2007) demonstrated that MYB98 functions
as a ...

The nucleus of the egg cell is not markedly different from the synergid nucleus
except for a slightly larger size. The egg cytoplasm contains plastids and
ribosomes. Ultrastructural studies have revealed that mitochondria in the egg cell
have ...
