| 2 | Persulfidation-induced Structural Change of SnRK2.6 Establishes Intramolecular Interaction between Phosphorylation and Persulfidation.显示文摘Post-translational modifications (PTMs) regulate the activity of SNF1-RELATED PROTEIN KINASE2.6 (SnRK2.6), including phosphorylation and persulfidation. Here, we report how persulfidations and phosphorylations of SnRK2.6 influence each other. The persulfidation of cysteine C131/C137 altered SnRK2.6 structure, resulted in serine S175 residue more close to aspartic acid D140, who belong to ATP-γ-phosphate proton acceptor may effectively improve the transfer efficiency of phosphate groups to S175, thus persulfidation enhanced the phosphorylation level of S175. S267 and C137 were predicted to lie in close proximity on the protein surface. The phosphorylation status of S267 positively regulated the persulfidation level at C137. Tests of responses of dephosphorylated and depersulfidated mutants to ABA and the H2S-donor NaHS during stomatal closure, water loss, gas-exchange, Ca2+ influx and drought stress revealed that S175/S267-associated phosphorylation and C131/137-associated persulfidation are essential for SnRK2.6 function in vivo. Taken together, we propose a mechanistic model in which certain phosphorylations facilitate persulfidation, which changes SnRK2.6 structure and increases its activity. | Sisi Chen Xiaofeng Wang Honglei Jia Fali Li Ying Ma Johannes Liesche Mingzhi Liao Xueting Ding Cuixia Liu Ying Chen Na Li Jisheng Li | 2021 | Molecular Plant2021，14，11： | 0 |
| 3 | Multimodal collaborative BCI system based on the improved CSP feature extraction algorithm显示文摘Background As a novel approach for people to directly communicate with an external device,the study of brain-computer interfaces(BCIs)has become well-rounded.However,similar to the real-world scenario,where individuals are expected to work in groups,the BCI systems should be able to replicate group attributes.Methods We proposed a 4-order cumulants feature extraction method(CUM4-CSP)based on the common spatial patterns(CSP)algorithm.Simulation experiments conducted using motion visual evoked potentials(mVEP)EEG data verified the robustness of the proposed algorithm.In addition,to freely choose paradigms,we adopted the mVEP and steady-state visual evoked potential(SSVEP)paradigms and designed a multimodal collaborative BCI system based on the proposed CUM4-CSP algorithm.The feasibility of the proposed multimodal collaborative system framework was demonstrated using a multiplayer game controlling system that simultaneously facilitates the coordination and competitive control of two users on external devices.To verify the robustness of the proposed scheme,we recruited 30 subjects to conduct online game control experiments,and the results were statistically analyzed.Results The simulation results prove that the proposed CUM4-CSP algorithm has good noise immunity.The online experimental results indicate that the subjects could reliably perform the game confrontation operation with the selected BCI paradigm.Conclusions The proposed CUM4-CSP algorithm can effectively extract features from EEG data in a noisy environment.Additionally,the proposed scheme may provide a new solution for EEG-based group BCI research. | Cunbo LI Ning LI Yuan QIU Yueheng PENG Yifeng WANG Lili DENG Teng MA Fali LI Dezhong YAO Peng XU | 2022 | Virtual Reality & Intelligent Hardware2022，4，1： | 0 |
