Abstract :
MicroRNA166 (miR166) contributes to post-transcriptional regulation by binding the mRNAs of HD-ZIP III genes, which affects plant growth and development. The structural characteristics, expression, and functions of miR166 genes during the early somatic embryogenesis stage in Dimocarpus longan remain unknown. We isolated the transcripts of pri-miR166 S78 with two transcription initiation sites (TSSs) and pri-miR166 S338 with one TSS. These sequences contain potential smORFs and encode different miRNA peptides (miPEPs). Additionally, their promoters contain cis-acting elements responsive to diverse stimuli. The pre-miR166 S78 and pre-miR166 S338 expression levels were up-regulated in response to 2,4-D, abscisic acid, and ethylene. Although the expression patterns induced by hormones were similar, there were differences in the extent of the response, with pre-miR166 S338 more responsive than pre-miR166 S78. Thus, miRNA transcription and maturation are not simply linearly correlated. Moreover, pre-miR166 S78 and pre-miR166 S338 expression levels were downregulated, whereas ATHB15 (target gene) expression was up-regulated, from the longan embryonic callus to the globular embryo stages. These results are indicative of a negative regulatory relationship between miR166 and ATHB15 during the early somatic embryogenesis stage in longan. At the same stages, miR166a.2-agomir, miR166a.2-antagomir, and miPEP166 S338 increased or decreased the expression of miR166a.2 and ATHB15, but with no consistent patterns or linear synchronization, from which we've found some reasons for it.

Abstract :
大学水平的高低直接取决于大学中的师资队伍水平,师资队伍结构不良将影响师资队伍整体水平的发挥。以福建农林大学为案例,选用高职称教师比例、中青年教师比例、高学位教师比例、具有外校学缘教师比例作为衡量师资队伍结构状况的指标,使用聚类分析法分析的结果显示:总体上学校师资队伍结构好;在16个学院中,师资队伍结构属于好的有8个,属于较好的有3个,属于中的有3个,属于差的有2个。各个类别的师资队伍结构特征,可以为相应学院的师资队伍建设和规划提供参考。聚类分析方法也可为其他地方高校解决师资队伍结构不良问题提供新的视角。

Abstract :
Tieguanyin Oolong tea (Camellia sinensis (L) O. Kuntze) is a name brand important commodity for Anxi county, Fujian province in China. Four-year-old tea plants at a tea plantation in Anxi were subjected to six different irrigation treatments (i.e. 5, 10, 15, 20, and 25 d irrigation intervals for T-1 to T-5 with a rate of 3.5 kg water per plant, plus a non-irrigated control). After 50 d of irrigation treatments, leaf water potential was -1.70, -2.34, -2.48, -2.89, -3.55, and -4.92 MPa for treatment T-1, T-2, T-3, T-4, T-5, and control, respectively. Leaf biomass yield increased by 32.8%, 21.9%, and 21.3% for T-1, T-2, and T-3, respectively, compared to control. The net photosynthesis (Pn), stomatal conductance (gs) and transpiration (E) decreased with irrigation interval increasing. Tea polyphenol (TP) and free amino acid (AA) decreased when the irrigation intervals were increased, but caffeine (CA) content apparently increased as the irrigation intervals were increased. To balance irrigation water demand and tea yield and quality, it is recommended that the irrigation interval should be set at 10 d with a rate of 3.5 kg water per plant for the optimal production in Anxi, Fujian province of China.
