Citrus canker, caused by Xanthomonas axonopo-dis pv. citri ('Xac'), is an important quarantine disease in citrus crops. Arbuscular mycorrhizal fungi (AMF) form symbiotic interactions with host plants and further affect their disease resistance, possibly by modulating the activity of salicylic acid (SA), a key phytohormone in disease resistance. Common mycorrhizal networks (CMNs) can interconnect plants, but it is not yet clear whether CMNs promote resistance to citrus canker and, if so, whether SA signaling is involved in this process. To test this possibility, we used a two-chambered rootbox to establish CMNs between trifoliate orange (Poncirus trifoliata) seedlings in chambers inoculated (treated) or not (neighboring) with the AMF, Paraglomus occultum. A subset of the AMF-inoculated seedlings were also inoculated with Xac (+AMF+Xac). At 2 d post-inoculation (dpi), compared with the +AMF-Xac treatment, neighboring seedlings in +AMF+Xac treatment had lower expression levels of the SA biosynthetic genes, PtPAL, PtEPS1, and PtPBS3, but higher SA levels, which attributed to the upregulation of PtPAL and PtPBS3 in treated seedlings and the transfer of SA, via CMNs, to the neighboring seedlings. At 4 dpi, the pathogenesis-related (PR) protein genes, PtPR1, PtPR4, and PtPR5, and the transcriptional regulatory factor gene, PtNPR1, were activated in neighboring seedlings of+AMF+Xac treatment. At 9 dpi, root phenylalanine ammo-nia-lyase activity and total soluble phenol and lignin concentrations increased in neighboring seedlings of+AMF+Xac treatment, likely due to the linkage and signal transfer, via CMNs. These findings support the hypothesis that CMNs transfer the SA signal from infected to neighboring healthy seedlings, to activate defense responses and affording protection to neighboring plants against citrus canker infection.

The metadynamic recrystallization （MDRX） behavior of as-cast 904L superaustenitic stainless steel was in- vestigated by double pass isothermal compression tests at temperatures of 950-1 150 ℃, strain rates of 0.05-5 s 1 and interval of 1-100 s. The effects of working parameters （deformation temperature, strain rate, pre-strain and in- terval time） on the flow curves and microstructural evolution were discussed. The MDRX fraction increased obvious- ly with the increase of deformation temperature, strain rate and interval time. The MDRX softening was controlled by the migration of grain boundary, annihilation of dislocation and dynamic recrystallization. Moreover, the kinetic model was established for the prediction of MDRX behavior of as-cast 904L superaustenitic stainless steel based on the experimental data. A good agreement between the predicted and the experimental values was achieved （correla- tion coefficient R2= 0.98）, indicating a satisfactory accuracy.

The emission of coumarin 6（C-6） doped in opal polymethylmethacrylate（PMMA） photonic crystal（PC） was effectively manipulated. Meanwhile the energy transfer（ET） of C-6 in PCs, which are infiltrated with sulforho- damine B（S-B）, was influenced by the concentration of energy acceptor in solution, the size of PMMA micro- sphere（SM） and the photonic stop band（PSB）. The results should be beneficial to people to further understand the potential application of PCs in optoelectronic fields.

The semiconducting properties of passive films grown on 00Crl3Ni5Mo2 supermartensitic stainless steel were investigated in comparison with conventional 2Cr13 martensitic stainless steel. Cyclic vohammetry and electro- chemical impedance spectroscopy （EIS） were used for the studies. 00Crl3NiSMo2 steel exhibited a good corrosion resistance performance, attributing to its passive capability. The results of Mott-Schottky analysis demonstrated n- type semiconductors for the passive films with doping densities of about 1020- 1021 cm -3, and the thickness of space- charge layers was also calculated. The experimental results confirmed that Mo plays an important role in improving the corrosion resistance of 00Crl3Ni5Mo2 steel due to its impact on the doping density.

The microstructural evolution and mechanical property of 00Crl3NiSMo2 supermartensitic stainless steel （SMSS） subjected to different heat treatments were investigated. Room tensile tests, hardness tests, scanning elec- tron microscopy, transmission electron microscopy and X ray diffraction were conducted on the heat-treated steels. It is found that the microstructure of the heat-treated steel is composed of tempered lath martensite, retained austenite and ^-ferrite. The austenitizing temperature and tempering temperature have a significant effect on the microstrtlctur al changes, which leads to the complex variations of mechanical properties. The fine tempered lath martensite and more dispersed reversed austenite in the microstructure facilitate improving the comprehensive mechanical properties of the studied steel. The optimal heat treatment process of 00Crl3Ni5Mo2 SMSS is obtained by austenitizing at 1000 ℃ for 0.5 h＋air cooling followed by tempering at 630 ℃ for 2 h＋air cooling, where the excellent combination of ten- sile strength, elongation and hardness can be achieved.
