The colour of the coleoptile of wheat. 2. A review and geographical distribution of the purple coleoptile of Triticum aestivum

Euphytica, 1973
This paper reviews the use of purple/green coleoptiles in wheat variety description, the identification of the anthocyanidins and anthocyanins of the purple coleoptile, its genetics and association with other characteristics. The geographical distribution of 902 Old World local varieties or their selections with purple or green coleoptile were ...

Peroxisomes in Rice Coleoptiles Grown in Air and in Anoxia

Botanica Acta, 1989
AbstractRice coleoptiles grow under anoxia. When the ultrastructure of anoxic coleoptile cells was examined, it was seen that most organelles maintain their integrity, with the exception of peroxisomes (unspecialized type). The lack of O2 greatly reduced the number of these organelles and altered the ultrastructure of the remaining ones. To examine the

Peroxidase isoenzymes of the Avena coleoptile

Phytochemistry, 1974
Abstract The bulk of the peroxidases of Avena coleoptile sections exist in soluble and salt-extractable, wall-associated fractions with lesser amounts in membranous and wall-bound fractions. In the presence of auxin the peroxidase levels remain nearly constant while in the absence of auxin the peroxidase of each fraction increases 2-to 6-fold in 22

Dextranase Activity in Coleoptiles of Avena

Science, 1970
An enzyme activity similar to that of dextranase is associated with coleoptiles of Avena sativa . When subjected to purified dextranase, both the pure natural dextran and the cell walls of the Avena coleoptiles yield isomaltose and isomaltotriose.

Auxine in Maiskoleoptilen

Planta, 1967
Aqueous diffusates and ether and ethanol extracts from tips of corn coleoptiles contain two ether soluble auxins. It could be shown by paper chromatography, electrophoresis and staining reactions that one of these (A1) is IAA. The second auxin (A2) is a bound form which was easily converted to IAA under mild conditions.

The Auxin Receptor in Corn Coleoptiles

1987
A common approach to isolate hormone receptors is the preparation of a protein fraction with high affinity to a particular hormone. The search for an auxin receptor can be traced back to 1972 when Hertel and his coworkers prepared a membrane fraction with auxin binding activity.

The Intercellular Spaces of the Avena Coleoptile

Physiologia Plantarum, 1966
AbstractIn the transverse sections of fresh Avena coleoptile certain intercellular spaces are transparent, others are dark. The transparent spaces represent the result of water‐logging of the originally water‐lined air passages. The dark spaces are lined with a plastic lipid‐containing membrane which can be impregnated with melted paraffin.

Ortho-geotropism in shoots and coleoptiles

1962
The first changes induced by gravity in a horizontally placed organ have been discussed by Brauner in the preceding Chapter of this Volume. This primary polarization the geotropic problem par excellence — is followed by secondary processes etc. which result in a different rate of growth of upper and lower side of the organ, and hence in the development
