Trap gland morphology and its systematic implication in Taiwan Utricularia. == Yi-Shan Chao*, Ho-Yih Liu, Yuen-Po Yang. Department of Biological Sciences, National Sun Yat-Sen University.
=========================================
In aquatic carnivorous plants genus Utricularia, highly specific glands play a very important role in digestion and absorption. However, there were few morphological studies in this genus. In this study, the scanning electron microscope was used to investigate the gland morphology of Taiwan Utricularia. Eight species were recorded in Taiwan, and six species were studied: U. aurea Lour., U. australis R. Br., U. bifida L., U. caerulea L., U. gibba L., and U. striatula Sm. The glands on both outer and inner surfaces of the trap were fully examined. There are three types of external glands and two types of internal glands. The external glands had little diagnostic value, but the internal glands could be used in species identification. Furthermore, the evolution transformation series of gland character can be inferred from known molecular phylogeny. The systematic value of gland morphology was discussed.
csyin 大大或許認識吧?
噢..別叫我大大, 你才是大大啦~ 你說的這些人我不認識... 不過這幾個人應該是: Yi-Shan Chao -> 趙怡姍 (研究生) Ho-Yih Liu -> ? Yuen-Po Yang -> 楊遠波 (指導教授)
