Somatic embryogenesis requires auxin and establishment of the shoot apical meristem (SAM). WUSCHEL (WUS) is critical for stem cell fate determination in the SAM of higher plants. However, regulation of WUS expression by auxin during somatic embryogenesis is poorly understood. Here, we show that expression of several regulatory genes important in zygotic(More)
Auxin and cytokinin signaling participates in regulating a large spectrum of developmental and physiological processes in plants. The shoots and roots of plants have specific and sometimes even contrary responses to these hormones. Recent studies have clearly shown that establishing the spatiotemporal distribution of auxin and cytokinin response signals is(More)
Neuromuscular transmission in the Chinese cobra Naja naja atra was not affected by its own toxin (cobrotoxin) at a concentration of as high as 100 microM, while in the frog a concentration of less than 0.1 microM cobrotoxin depressed the amplitude of the end-plate potential to less than 10% of its original value within 30 min or directly blocked the(More)
The effects of river rehabilitation on flood reduction in the Steinsel sub-basin of the Alzette River basin, Grand-Duchy of Luxembourg, are discussed; the rehabilitation measures include planting and changing riparian and in-stream vegetation, and re-meandering of channelised reaches, etc. in the headwater streams. To simulate flood reduction by river(More)
This paper describes the development of a comprehensive subcatch-ment parameterization method for medium and large-scale watershed modelling based upon the fully distributed WetSpa model. A simplified approach is used in order to take advantage of the existing spatial analysis function within ArcView GIS and its Spatial Analyst and hydrological modelling(More)
Cisplatin and its analogues are widely used as anti-tumor drugs in lung cancer but many cisplatin-resistant lung cancer cases have been identified in recent years. Single-stranded DNA-binding protein 1 (SSDBP1) can effectively induce H69 cell resistance to cisplatin in our previous identification; thus, it is necessary to explore the mechanism underlying(More)
MicroRNAs (miRNAs) are single-stranded small, endogenous RNAs that can downregulate gene expression in plants and animals. Plant miRNAs are already known to function in many biological processes during plant development by targeting mRNA for degradation or repression. Somatic embryogenesis is used as a model to investigate miRNAs associated with(More)
