Additionally, several types of chromosome aberrations were observed in somatic cells of the normal alpacas .

此外，本研究还观察到正常羊驼染色体畸变类型，包括数目畸变和结构畸变，数目畸变如三倍体、四倍体；

Comparing as BA, 0.1mg·L〓 TDZ was more effective in inducing germinating and developing of buds, regenerating prolific caespitose buds via organogenesis, promoting rhizogenesis and activity of root system greatly, as a result, acclimation survival rate was improved significantly. When leaf segments, cut from in vitro plantlets, were placed on MS media containing 0.1mg·L〓 TDZ, adventitious buds regenerated from segments. After transferred to propagated and rooted media, adventitious buds would proliferate and come into full plantlets.

与BA相比，TDZ的细胞分裂素活性至少高出一个数量级，0.1mg·L〓的TDZ能有效地诱导四个基因型芋茎尖的萌动、生长、大量增殖丛生芽，促进试管苗根系发生，将根系活力提高2倍以上，显著提高了试管苗的驯化成活率；浓度为0.01mg·L〓的TDZ能诱导魁芋类型的芋离体叶片切块产生再生芽点，转接后可增殖不定芽并形成再生植株。

Four steady state microbial communities were established in chemostats using inocula from human feces. Three chemostats were exposed to enrofloxacin 0.2, 2, and 20 mgL^(-1, respectively for 8 days; one served as a no-drug control.

四套接种人体肠道菌群的离体恒化器模型中连续添加0、0.2、2及20mgL^(-1)恩诺沙星8d，采用细菌培养计数和PCR-DGGE方法研究细菌数量、耐药性、菌群结构和定植抗力的变化。
