In vitro pollen tubes respond chemotropically to low molecular weight ions and
molecules, pistil tissues and their extracts from many plant species (Mascarenhas
and Machlis, 1962a,b; Reger etal., 1992a,b). Ca2* has been shown to attract ...

INTERNATIONAL REVIEW OF CYTOLOGY
Their results seemed to prove that the putative chemotropically active factor was
synthesized and released by secretory surface cells. The experiments of
Mascarenhas and Machlis (1962a,b, 1964) showed that in artificial media
calcium was ...

CURRENT TOPICS DEVELOPMENTAL BIOLOGY
There is one report of Schildknecht and Benoni (1963b) on the nature of
chemotropic substances. These workers isolated chemotropically active
substances from ovules of Oenothera and found among them amino acids,
peptides, a primary ...

Biocommunication of Fungi
A specialized hypha called the trichogyne emanates from the protoperithecium
and then grows chemotropically towards a male cell (macroconidium,
microconidium, hyphal segment) of opposite mating type. Upon contact, the
trichogyne and ...

Molecular Embryology of Flowering Plants
This finding led to the search for inorganic ions and to the discovery that Ca2* is
chemotropically active for pollen tubes of A. majus, Narcissus pseudonarcissus,
and Clivia miniata (Mascarenhas and Machlis 1962a, 1964). It was also found ...

Pollen: Development and Physiology
Whether the colloidal bodies discussed in the preceding section provide
precursors for the .synthesis of chemotropically active substances remains to be
determined. At the present time the nature of the chemotropic agent remains
unknown.

Behaviour of micro-organisms: based on the proceedings of ...
Pollen from many plants is able to respond chemotropically to vegetative tissue
and to pistil tissues from related and unrelated plant species (see review by
Mascarenhas and Machlis, 1962a). Hence, the chemotropic factor (s) seems to
be ...

Cytomorphogenesis in Plants
In pollen tubes of Antirrhinum, Ca21 is chemotropically active (Mascarenhas and
Machlis 1962) but is chemotropically inactive in Lilium (Rosen 1971) and in
Oenothera (Glenk et al. 1971). Chemotropically active substances, which direct
the ...

Plant Tropisms: And Other Growth Movements
And thirdly, if a chemical is having a specific effect on growth it must be
interacting with a specific receptor, which is likely to be located on the cell
membrane; therefore, chemotropically effective chemicals, and their analogues
and competitors, ...
