Arabidopsis synaptotagmin 2 （SYT2） has been reported to participate in an unconventional secretory pathway in somatic cells. Our results showed that SYT2 was expressed mainly in the pollen ofArabidopsis thaliana. The pollen of syt2 T-DNA and RNA interference mutant lines exhibited reduced total germination and impeded pollen tube growth. Analysis of the expression of SYT2-GFP fusion protein in the pollen tube indicates that SYT2 was localized to distinct, patchy compartments but could co-localize with the Golgi markers, BODIPY TR C5 ceramide and GmManl-mCherry. However, SYT2-DsRed-E5 was localized to the plasma membrane in Arabidopsis suspension cells, in addition to the Golgi apparatus. The localization of SYT2 at the plasma membrane was further supported by immunofluorescence staining in pollen tubes. Moreover, brefeldin A treatment inhibited the transport of SYT2 to the plasma membrane and caused SYT2 to aggregate and form enlarged compartments. Truncation of the SYT2-C2AB domains also resulted in retention of SYT2 in the Golgi apparatus. An in vitro phospholipid-binding assay showed that SYT2-C2AB domains bind to the phospholipid membrane in a calcium-dependent manner. Take together, our results indicated that SYT2 was required for pollen germination and pollen tube growth, and was involved in conventional exocytosis.

历史时期罗布泊地区环境演变过程

利用史学考据的方法之一"二重证据法",从历史时期不同阶段进行纵向比较和从同一时期不同地区进行横向比较入手,参考放射性碳素断代法(即14C测定法)对太阳墓遺址、楼兰遺址进行断代测定的結果,结合应用空间遥感技术,对楼兰故城上游地质... 详细信息

利用史学考据的方法之一"二重证据法",从历史时期不同阶段进行纵向比较和从同一时期不同地区进行横向比较入手,参考放射性碳素断代法(即14C测定法)对太阳墓遺址、楼兰遺址进行断代测定的結果,结合应用空间遥感技术,对楼兰故城上游地质滑坡形成堰塞湖卫星图像的解读数据,分析新疆楼兰古城消亡的原因和罗布泊地区环境演变的过程。结果显示,历史时期罗布泊地区的环境演变与人类活动密切相关:土地掠夺性开垦,水资源的超常规开采,植物种群的大面积采伐都是造成生态环境变化的原因。对水土资源的的超常规开采和过度使用,也是导致楼兰故城废弃的原因。需要说明的是,这是一个渐进的过程。沒有证据可以直接证明,滑坡崩塌形成堰塞湖使孔雀河突然断流,导致楼兰城供水突然中断。

东天山造山带的图拉尔根镁铁-超镁铁杂岩体为一个早古生代长期活动的幔源岩浆通道,大型铜镍钴硫化物矿体赋存于Ⅰ号超镁铁质岩体的顶部,不同类型岩石中辉石矿物的流体挥发份化学组成以H2O为主(平均91%,5400.4mm3/g),其次为H2(2.0%)、H2S(2.3%)和CO2(2.1%);赋矿角闪橄榄岩中CO2和H2S含量最高,辉长岩中流体挥发份含量低于辉石橄榄岩和橄榄辉石岩等岩浆早期结晶的岩石。CO2和CH4的δ13C值位于地壳与甲烷氧化的范围内,甲烷同系物的碳同位素组成具有正序分布模式,部分样品(TLG512)释出的CH4和C2H6具有较重的δ13C值和反序分布特征。表明I号岩体不同类型岩石可能是不同期次岩浆活动的产物,成矿岩浆具有富H2O和H2S的特征,可能起源于被流体交代的亏损地幔源区,混染壳源组分可能为俯冲板片来源蚀变沉积有机质组分。
