Removing the panicle encourages the growth of buds on the elongated node by getting rid of apical dominance. Strigolactones (SLs) are plant hormones that suppress tillering in rice. The present study employed panicle removal (RP) and external application of synthesized strigolactones (GR) to modulate rice bud growth at node 2. We focused on the full-heading stage to investigate proteomic changes related to bud germination (RP-Co) and suppression (GR-RP). A total of 434 represented differentially abundant proteins (DAPs) were detected, with 272 DAPs explicitly specified in the bud germination process, 106 in the bud suppression process, and 28 in both. DAPs in the germination process were most associated with protein processing in the endoplasmic reticulum and ribosome biogenesis. DAPs were most associated with metabolic pathways and glycolysis/gluconeogenesis in the bud suppression process. Sucrose content and two enzymes of sucrose degradation in buds were also determined. Comparisons of DAPs between the two reversed processes revealed that sucrose metabolism might be a key to modulating rice bud growth. Moreover, sucrose or its metabolites should be a signal downstream of the SLs signal transduction that modulates rice bud outgrowth. Contemplating the result so far, it is possible to open new vistas of research to reveal the interaction between SLs and sucrose signaling in the control of tillering in rice. [ABSTRACT FROM AUTHOR]

• Avian influenza A(H7N9) virus caused serious disease and threaten to public health. • Five human cases were investigated during the surveillance in 2017, Gansu, China. • Positive A(H7N9) environmental samples were detected in the same location and period. • At least two routers, via which A(H7N9) viruses were introduced to Gansu, in 2017. Avian H7N9 influenza virus, which emerged in 2013 China, had caused the fifth wave of peaks in 2016–2017. Gansu Province locate in western China far away from the epicenter of the virus, also detected cases in this wave. During the monitoring, five human cases with H7N9 virus infection, three cases in Jiuquan and two cases in Zhangye, were reported and investigated. A total of 88 environmental samples collected from March to June, in poultry farms and live poultry markets were H7N9 positive by real time RT-PCR assay. The two human viruses were identified as LPAI viruses, and phylogenetic analysis showed that the viruses might be introduced into Gansu by two distinct trade routes. Avian influenza H7N9virus posed a pandemic potential to threaten human health, and monitoring among birds and the environment should be strengthened. [ABSTRACT FROM AUTHOR]
