| species-specific scar markers for authentication of sinocalycanthus chinensis. | sinocalycanthus chinensis, an endangered species endemic to china, is cultivated as an ornamental landscape tree in china. however, s. chinensis, chimonanthus species and calycanthus floridus are difficult to be distinguished in seedling market because of their similar morphological characters. in this study, issr (inter-simple sequence repeats) were applied to detect s. chinensis from its closely related species. a unique 748-bp band was found in all accessions of s. chinensis. scar (sequence c ... | 2006 | 17048299 |
| correlation between pollen aperture pattern and callose deposition in late tetrad stage in three species producing atypical pollen grains. | • premise of the study: pollen grains of flowering plants display a fascinating diversity of forms, in spite of their minute size. the observed diversity is determined by the developmental mechanisms implicated in the establishment of pollen morphological features. pollen grains are generally surrounded by an extremely resistant wall interrupted in places by apertures that play a key role in reproduction, being the places at which pollen tube growth is initiated. aperture shape, number, and posi ... | 2011 | 21613108 |
