| 1 | OsSIDP366,a DUF1644 gene,positively regulates responses to drought and salt stresses in rice显示文摘Domain of unknown function 1644(DUF1644) is a Rhighly conserved amino acid sequence motif present only in plants. Analysis of expression data of the family of DUF1644-containing genes indicated that they may regulate responses to abiotic stress in rice. Here we present our discovery of the role of Os SIDP366, a member of the DUF1644 gene family, in response to drought and salinity stresses in rice. Transgenic rice plants overexpressing Os SIDP366 showed enhanced drought and salinity tolerance and reduced water loss as compared to that in the control, whereas plants with downregulated Os SIDP366 expression levels using RNA interference(RNAi) were more sensitive to salinity and drought treatments. The sensitivity to abscisic acid(ABA)treatment was not changed in Os SIDP366-overexpressing plants, and Os SIDP366 expression was not affected in ABAdeficient mutants. Subcellular localization analysis revealed that Os SIDP366 is presented in the cytoplasmic foci that colocalized with protein markers for both processing bodies(PBs) and stress granules(SGs) in rice protoplasts. Digital gene expression(DGE) profile analysis indicated that stress-related genes such as SNAC1, Os HAK5 and PRs were upregulated in Os SIDP366-overexpressing plants. These results suggest that Os SIDP366 may function as a regulator of the PBs/SGs and positively regulate salt and drought resistance in rice. | Chiming Guo Chengke Luo Lijia Guo Min Li Xiaoling Guo Yuxia Zhang Liangjiang Wang Liang Chen | 2016 | Journal of Integrative Plant Biology2016，58，5： | 10 |
| 2 | Optimal maintenance decisions for gamma deteriorating systems显示文摘An optimal replacement model for gamma deteriorating systems is studied.This methodology uses a gamma distribution to model the material degradation,and the impact of imperfect maintenance actions on the system reliability is investigated.The state of a degrading system immediately after the imperfect maintenance action is assumed as a random variable and the maintenance time follows a geometric process.A maintenance policy(N) is applied by which the system will be repaired whenever it experiences Nth preventive maintenance(PM),and an optimal policy(N) could be determined numerically or analytically for minimizing the long-run average cost per unit time.Finally,a numerical example is presented to demonstrate the use of this policy. | Lin Tan Chiming Guo Zhijun Cheng Bo Guo | 2011 | Journal of Systems Engineering and Electronics2011，22，5： | 2 |
