This phenomenon warrants further study. 4. Phylogeny study on Croomia and Stemona The relationship of the genus and the taxonomic placement of Stemonaceae The phylogenetic tree of matK, trnL-F, atpB-rbcL and ITS sequences data indicated that it was natural to place Stemona and Croomia in one family.

黄精叶钩吻属和百部属的分子系统学研究百部科属间关系和科的系统地位叶绿体DNA(matK、trnL-F和atpB-rbcL)及核DNA序列构建的系统树显示Stemona和Croomia形成稳定的单系类群，表明将这两个属放在同一个科是自然的，不支持将Croomia独立成科。

Therefore, the LsHNXs genes were cloned in this study, and their function was studied by RNAi. The main results were shown as follows:1 The conservative sequences of three LsHNXs genes (LsHNX1, LsHNX2, and LsHNX3), and the 3'-terminal specific sequences of LsHNX2 and LsHNX3, were cloned by RT-PCR and 3'-RACE.2 The plant RNAi vectors were constructed and the transformation of Limonium sinense was done. The RNAi lines of three single-genes and one double-gene were obtained and were propogated rapidly for the molecular and the stress tolerance analysis.3 To be compared with wild type, the Na+ and K+ contents secreted by the leaves of LsNHX1 transgenic plants were remarkably higher.

The nine tested tea cultivars were categorized into three groups by cluster analysis according to the number of probes per insect, waveform durations, or duration per probe including various waveforms on different tea cultivars. Waveforms S, E and F correlated to the main feeding activity of the leafhoppers and may provide valuable information on predicting the resistance levels of the tea plants to the leaThopper. The resistance level of the nine tea cultivars to the leafhopper was ranked based on the durations of waveform S, E and F, as well as the duration every probe including various waveforms.
