| 1 | Lipids and membrane-associated proteins in autophagy显示文摘Autophagy is essential for the maintenance of cellular homeostasis and its dysfunction has been linked to various diseases.Autophagy is a membrane driven process and tightly regulated by membrane-associated proteins.Here,we summarized membrane lipid composition,and membrane-associated proteins relevant to autophagy from a spatiotemporal perspective.In particular,we focused on three important membrane remodeling processes in autophagy,lipid transfer for phagophore elongation,membrane scission for phago-phore closure,and autophagosome-lysosome membrane fusion.We discussed the significance of the discoveries in this field and possible avenues to follow for future studies.Finally,we summarized the membrane-associated biochemical techniques and assays used to study membrane properties,with a discussion of their applications in autophagy. | Linsen Li Mindan Tong Yuhui Fu Fang Chen Shen Zhang Hanmo Chen Xi Ma Defa Li Xiaoxia Liu Qing Zhong | 2021 | Protein & Cell2021，12，7： | 3 |
| 2 | Transcriptomic and genetic approaches reveal that low-light-induced disease susceptibility is related to cellular oxidative stress in tomato显示文摘The impact of low light intensities on plant disease outbreaks represents a major challenge for global crop security,as it frequently results in significant yield losses.However,the underlying mechanisms of the effect of low light on plant defense are still poorly understood.Here,using an RNA-seq approach,we found that the susceptibility of tomato to Pseudomonas syringae pv.tomato DC3000(Pst DC3000)under low light was associated with the oxidation-reduction process.Low light conditions exacerbated Pst DC3000-induced reactive oxygen species(ROS)accumulation and protein oxidation.Analysis of gene expression and enzyme activity of ascorbate peroxidase 2(APX2)and other antioxidant enzymes revealed that these defense responses were significantly induced by Pst DC3000 inoculation under normal light,whereas these genes and their associated enzyme activities were not responsive to pathogen inocula-tion under low light.Additionally,the reduced ascorbate to dehydroascorbate(AsA/DHA)ratio was lower under low light compared with normal light conditions upon Pst DC3000 inoculation.Furthermore,the apx2 mutants generated by a CRISPR-Cas9 gene-editing approach were more susceptible to Pst DC3000 under low light conditions.Notably,this increased susceptibility could be significantly reduced by exogenous AsA treatment.Collectively,our findings suggest that low-light-induced disease susceptibility is associated with increased cellular oxidative stress in tomato plants.This study sheds light on the intricate relationship between light conditions,oxidative stress,and plant defense responses,and may pave the way for improved crop protection strategies in low light environments. | Qian Luo Jiao Wang Ping Wang Xiao Liang Jianxin Li Changqi Wu Hanmo Fang Shuting Ding Shujun Shao Kai Shi | 2023 | Horticulture Research2023，10，10： | 0 |
