ENDOTHECIUM IN IRIDACEAE AND ITS SYSTEMATIC IMPLICATIONS

American Journal of Botany, 1990
An examination of the endothecial thickenings in 44 species of Iridaceae, selected from the four subfamilies and all major tribes, provides useful information about generic and tribal relationships in the family. U‐shaped thickenings occur in Nivenioideae and Iridoideae—Sisyrinchieae, the latter the least specialized tribe of its ...

Fibrous Endothecium, Tapetum, and Pollen Development in Belamcanda chinensis DC.

Botanical Gazette, 1973
The ontogeny of the anthers of Belamcanda chinensis has been studied with special reference to the behavior of the tapetum and its influence on the development of the endothecium and fertile pollen. When the tapetum malfunctions (either hypertrophies or forms a persistent band), besides the development of sterile pollen, the endothecium neither attains

Development and Histochemistry of the Endothecium in the Anthers of In vitro Grown Chenopodium rubrum L.

Botanical Gazette, 1969
Seedlings of Chenopodium rubrum were grown on a fully defined medium and induced to flower by exposure to cycles of 8 hr light/16 hr darkness. The development of the anthers was studied using histochemical techniques. Particular attention was paid to the delayed development of the endothecium or fibrous layer and to the chemistry of the endothecial ...

Analysis of the molecular mechanism regulating anther endothecium secondary thickening in Arabidopsis thaliana [PDF]

, 2020
Food security is important to feed a growing global population in a changing climate. Heterosis (the phenomenon of increased yield in hybrid crops) is a significant way to maximise crop yields without increasing input. One difficulty with breeding hybrid plants is preventing self-fertilisation, and there is therefore interest in male sterile plants in ...

FINE STRUCTURE OF THE ENDOTHECIUM AND DEVELOPING XYLEM IN PHASEOLUS VULGARIS

New Phytologist, 1982
SUMMARYDifferentially thickened wall bars are formed in cells of the anther endothecium as well as in the xylem. In Phaseolus vulgaris both types of wall bar appear to be lignified. As thickening takes place, Golgi bodies become numerous, endoplasmic reticulum proliferates and both types of organelle occupy characteristic sites within the cell ...
