By means of electron microscopy, we studied the development of pollen grain walls in Calendula officinalis L., Dimorphotheca aurantiaca DC., and Cichorium intybus L. (Asteraceae). As a reference, we studied the plants from the families Schisandraceae ( Schisandra chinensis (Turcz.) Baill.), ...
Our present research reports that a new cysteine protease, NtCP56, is involved in the development of pollen grains in Nicotiana tabacum L. The NtCP56 gene, which encodes a protein of 361 amino acid residues with a calculated molecular mass of 40 kDa, is strongly expressed in anthers. The ...
Mechanically, OsBZR1 directly promotes CSA expression and CSA directly triggers expression of sugar partitioning and metabolic genes during pollen and seed development. These findings provide insight into how BRs enhance plant reproduction and grain yield in an important agricultural crop. 展开 关键词:...
Proteins are stored in two sites in the pollen grain walls of the Malvaceae, () in the cellulosic intine, mainly in the vicinity of the circular apertures, and () in cavities in the sculptured layer of the exine. The intine-held material... HESLOP-HARRISON J.,HESLOP-HARRISON Y.,KNOX ...
These are both contained in the pollen grains that subsequently develop. The development of the pollen grain involves considerable loss of water vapor, so that by anthesis when pollen is finally shed the water content of the pollen may be as low as 9% and rarely more than 60%, depending ...

Furthermore, we found the phenomenon specific for ion beam exposure, " leaky pollen" resulted from a physical lesion(s) induced in outer wall (probably, exine) of pollen grain. If exogenous NDA can be incorporated into pollen cell through the cleavage induced by ion beam and transferred to ...
A study was made of the differential effects of specific chromosomal deficiencies on the development of the maize pollen grain. Twenty-six B鈥揂 translocations involving 17 of the 20 chromosome arms were used to produce hypoploid plants in which one half of the microspores had a predictable ...
Disruption (T-DNA insertion) of the SPIK coding sequence strongly affected inwardly rectifying K(+)-channel activity in the pollen-grain plasma membrane. Measurements of membrane potential in growing pollen tubes yielded data compatible with a contribution of SPIK to K(+) influx. In vitro pollen ...
