| 1 | Rheostatic Control of ABA Signaling through HOS15-Mediated OST1 Degradation显示文摘Dehydrating stresses trigger the accumulation of abscisic acid(ABA),a key plant stress-signaling hormone that activates Snf1-Related Kinases(SnRK2s)to mount adaptive responses.However,the regulatory circuits that terminate the SnRK2s signal relay after acclimation or post-stress conditions remain to be defined.Here,we show that the desensitization of the ABA signal is achieved by the regulation of OST1(SnRK2.6)protein stability via the E3-ubiquitin ligase HOS15.Upon ABA signal,HOS15-induced degradation of OST1 is inhibited and stabilized OST1 promotes the stress response.When the ABA signal terminates,protein phosphatases ABI1/2 promote rapid degradation of OST1 via HOS15.Notably,we found that even in the presence of ABA,OST1 levels are also depleted within hours of ABA signal onset.The unexpected dynamics of OST1 abundance are then resolved by systematic mathematical modeling,demonstrating a desensitizing feedback loop by which OST1-induced upregulation of ABI1/2 leads to the degradation of OST1.This model illustrates the complex rheostat dynamics underlying the ABA-induced stress response and desensitization. | Akhtar Ali Jae Kyoung Kim Masood Jan Haris Ali Khan Irfan Ullah Khan Mingzhe Shen Junghoon Park Chae Jin Lim Shah Hussain Dongwon Baek Kai Wang Woo Sik Chung Vicente Rubio Sang Yeol Lee Zhizhong Gong Woe Yeon Kim Ray ABressan Jose MPardo Dae-Jin Yun | 2019 | Molecular Plant2019，12，11： | 5 |

| 3 | A Study on the Mixed Use of Power Conversion Elements of Propulsion Control Devices in Railway Train显示文摘A study is under way to apply the main power conversion element of the C/I device,the propulsion control unit of variable voltage and variable frequency(VVVF),to the electric vehicle by changing it from gate turn off thyristor(GTO)to insulated gate bipolar transistor(IGBT).In an early study,a combination of GTO and IGBT was tested on electric vehicles.The IGBT method was applied to 1 coach and the GTO method was applied to the remaining coaches.As a result of the test,a lack of traction force occurred due to an imbalance in output current.This phenomenon was determined to be caused by differences in the operational characteristics of the two types of power devices.This is due to the different response performance of the IGBT inverter vehicle and switching signal of the controller that drives the existing GTO inverter.When two power devices are used in a train,it is necessary to match the response performance between coaches.Interface board was manufactured and installed on the coach with IGBT and tested.The interface board is designed to have the characteristics of matching signals between the controller and the gate drive unit(GDU).As a result,the same switching response performance was achieved between GTO type and IGBT type coaches.The performance of using a mix of two power devices was verified.Therefore,normal driving performance and comfortable ride were maintained during the operation of the train. | Dongwon Lim Hanmin Lee Jinhan Lee | 2020 | Journal of Energy and Power Engineering2020，14，2： | 0 |
