Exposures to poultry in markets were associated with A(H7N9) virus infection, even without poultry contact. China should consider permanently closing live poultry markets or aggressively pursuing control measures to prevent spread of this emerging pathogen.

The NO 3 - transporter plays an important role in rice nitrogen acquisition and nitrogen-use efficiency. Our previous studies have shown that the high affinity systems for nitrate uptake in rice is mediated by a two-component NRT2/NAR2 transport system. In this study, transgenic plants were successful developed by overexpression of OsNAR2.1 alone, OsNRT2.3a alone and co-overexpression of OsNAR2.1 and OsNRT2.3a . Our field experiments indicated that transgenic lines expressing p35S:OsNAR2.1 or p35S:OsNAR2.1-p35S:OsNRT2.3a constructs exhibited increased grain yields of approximately 14.1% and 24.6% compared with wild-type (cv. Wuyunjing 7, WT) plants, and the agricultural nitrogen use efficiency increased by 15.8% and 28.6%, respectively. Compared with WT, the 15 N influx in roots of p35S:OsNAR2.1 and p35S: OsNAR2.1-p35S:OsNRT2.3a lines increased 18.9%‑27.8% in response to 0.2 mM, 2.5 mM 15 NO 3 – , and 1.25 mM 15 NH 4 15 NO 3 , while there was no significant difference between p35S:OsNAR2.1 and p35S:OsNAR2.1-p35S:OsNRT2.3a lines; only the 15 N distribution ratio of shoot to root for p35S:OsNAR2.1-p35S:OsNRT2.3a lines increased significantly. However, there were no significant differences in nitrogen use efficiency, 15 N influx in roots and the yield between the p35S:NRT2.3a transgenic lines and WT. This study indicated that co-overexpression of OsNAR2.1 and OsNRT2.3a could increase rice yield and nitrogen use efficiency.

PurposeThis study aims to explore the impact of ethical leadership on employee creative deviance, with job autonomy as a mediator and creative self-efficacy as a moderator between job autonomy and creative deviance.Design/methodology/approachA survey was developed based on construct measures from the literature. A total of 316 responses were received from employees of information and communication technology companies located in China's Pearl River Delta.FindingsBoth ethical leadership and job autonomy have a positive impact on employee creative deviance; job autonomy plays a mediating role between ethical leadership and creative deviance; creative self-efficacy does not have a significant moderating effect on the job autonomy-creative deviance relationship.Research limitations/implicationsFuture studies could explore the potential moderating role of both job autonomy and creative-self efficacy in the link between ethical leadership and creative deviance.Practical implicationsThis study recommends that organizations should adopt and promote an ethical leadership approach to manage creative deviance at work. Organizations could explore alternative methods of task completion to support the job autonomy for the employees to mitigate the dilemmas associated with creative deviance.Originality/valueThis is one of few studies that examine the impact of ethical leadership on employee's creative deviance, despite the fact that the influence of ethical leadership on the followers has been extensively examined.
