The G 2 peak of tetraploids is approximately on channelwhile diploids showed a G 2 peak on channel Enhancing the productivity of secondary metabolites via induced polyploidy.
In grade 3, the situation is completely opposite and so, they are most similar to tetraploid plants. Genomic and ploidy manipulation for enhanced production of phyto-pharmaceuticals. This study showed that stomata characteristics markedly differed between diploid and tetraploid plants. Pakistan Journal of Biological Sciences, This is actually a genetic effect which can be seen in all organs, such as seeds, flowers, leaves and shoot.
Egyptian henbane Hyoscyamus muticus is one of the most important medicinal plant of the Solanaceae family. Hyoscyamus muticus Scientific classification Kingdom: Thus, as a simple and efficient method, the stomata size and chloroplast number can be used as markers to identify the ploidy level of this plant before flow cytometric analysis. In vitro tetraploid induction and generation of tetraploids frome mixoploids in hop Humulus lupulus L.
Flow cytometric profiles of colchicine-treated plants: In this study, the peak that represents the G 1 phase of the tetraploid cell cycle was located on channelwhereas for control this peak was on channel The stem histograms showed no significant difference with those of leaves, while the root histogram showed a higher difference.
The lower leaves are broad, while the upper leaves are narrower. In grade 1, the number of diploid nuclei is more than tetraploids, whereas in grade 2, the number is equal.
In this research to investigate the stability of the induced tetraploids, flow cytometry measurement was conducted again from leaves in C 1 and C 2 generations. In vitro chromosome doubling of nine Zantedeschia cultivars. The meristem tip of plantlets in their leaf stage were first covered with cotton Fig. An inverse relationship has been reported between colchicine concentration and explant survival with ex vitro Lavania, ; Lavania and Srivastava, and in vitro Hamill et al.
The first visible effect of colchicines was the delayed growth of treated plantlets. Visual observations also indicated strong correlation between increased polyploidy level and bigger vegetative organs, for those plantlets grown in greenhouse.
Solid, stable autotetraploids as well as mixoploids were produced by treating Egyptian henbane plantlets with colchicine. Also, no 8n nuclei peak in the flow cytometry histogram of control root samples was observed, hyoscyakus leaf and stem samples of this plants, in some cases showed a small percentage of 8n nuclei peaks.
Four months after planting, the aerial organs of diploid and tetraploid plants were collected for measuring their wet and dry weight. Colchicine has been used for chromosome doubling in many crops including banana Hamill et al.
Hyoscyamus – Wikipedia
Morphological differences between diploid and tetraploid Egyptian henbane: Male sterility was a visible effect of tetraploid induction of H. The wild plants are used in traditional local medicine.
The Tuareg people use it as a fish poison. Search in Google Scholar. It can be efficiently used hyosfyamus ploidy determination in plants growing in fields or in the greenhouse Dolezel et al.
It contains valuable tropane alkaloids, such as hyoscyamin and traces of hucin and atropine Lavania, It grows in arid rocky localities, wadis and plains. Regarding to the mixoploidy production in mutkcus treated meristems and remaining of diploid cells that proliferate at higher rates than tetraploid ones Mergen and Lester, it is possible that selected plants, partially or totally reversed to the diploid condition after successive cell division cycles.
These alkaloids are synthesized in roots and then transported to aerial parts of the plant Pal Bais et al. Usually leading to mixoploidy Roy et al.
