植物的一生常遭受各种胁迫,导致错误折叠蛋白或未折叠蛋白在细胞内积累,进而引发内质网胁迫。植物主要通过内质网质量监控系统(ER quality control,ERQC)、内质网相关降解(ER-associated degradation,ERAD)、未折叠蛋白反应(unfolded protein response,UPR)以及自噬来抵抗内质网胁迫。其中UPR是一种通过信号转导来增强蛋白质折叠和修复能力以及促进错误折叠蛋白降解的途径,植物UPR中IRE1和bZIP17/28两种途径已被证实。许多转录因子(transcription factors)参与响应内质网胁迫,主要涉及bZIP、NAC、HSF、WRKY和NF-Y核因子等基因家族,是作物抗逆遗传改良的目标基因,因此研究内质网应激调控机制具有重要意义。本文主要简述了内质网应激中ERQC、ERAD、UPR以及自噬反应的一般原理并对参与内质网应激的转录因子的调控机制研究进展进行综述,以期为植物内质网胁迫中转录因子的作用机制解析及作物抗逆遗传改良提供参考。

Acoustic transducer is an important part of acoustic well logging tool. In this paper,ANSYS software package is used to design acoustic dipole transducer and simulate vibrating mode of the dipole transducer in different mechanical boundary conditions. The results show that boundary conditions influence the number of vibrating mode in the same frequency band and the frequency value of the same vibrating mode. Several acoustic dipole transducers are designed according to the results of numerical simulation and laboratory measurements. The basic frequency of vibrating mode of experi-ment has good agreement with that of simulation. The numerical simulation plays a good guidance role in designing,producing and correctly installing the acoustic dipole transducer.
