Abstract： To comprehensively understand the effects of selenium (Se) supplementation on Codonopsis pilosula, effects of sodium selenite levels on Se accumulation, growth, physiology and quality were explored by using hydroponic experiments. The results were as follows: (1)Treatment with 0.2 mg∙L-1 Se promoted leaf size, plant height and biomass of C. pilosula, while treatment with 10 mg∙L-1 Se suppressed them. (2)Both increasing Se level and exposure time to C. pilosula seedlings could raise its Se content in roots and leaves, and Se was distributed in organs with an order of root>leaf>stem. (3)Treatment with 0.2 mg∙L-1 Se increased photosynthetic pigment contents and root activity, and reduced malondialdehyde, proline and hydrogen peroxide content, while treatment with 10 mg∙L-1 Se had opposite effects. (4)Treatment with 0.2 mg∙L-1 Se had positive effects on accumulations of lobetyolin, polysaccharides, and soluble protein, while treatment with 10 mg∙L-1 Se had negative effects on the accumulations of polysaccharides and soluble protein. Collectively, sodium selenite had dual effects on C. pilosula; Application of appropriate Se was beneficial to its growth, plant physiology and quality, and 0.2 mg·L-1 Se level was the optimum. This work may improve our understanding the effect of selenite level on the biology effect of C. pilosula, which would be useful for the basic research and cultivation of Se-enriched C. pilosula.

Abstract： Resurrection plants usually grow in extreme habitats and have the capacity to survive from lower relative water content to 10%. There are many resurrection plants in Gesneriaceae family, and the resuscitating mechanism of different species may be different. In order to investigate whether the two species have resurrection characteristics and their physiological mechanisms in response to drought, two species of Gesneriaceae, Paraboea rufescens and Oreocharis cordatula, which are distributed in subtropical and temperate limestone areas respectively, were selected in this study. Their leaves were dehydrated for 1, 2 and 3 d respectively, and then rehydrated for 1 day respectively. The leaf morphology, relative water content, photosynthetic activity, photosynthetic pigments, membrane integrity and osmotic adjustment substances during different dehydration and rehydration treatments were detected and analyzed. The results showed that the leaf discs of Paraboea rufescens folded inward after dehydration, and the leaf upper epidermis was completely wrapped after dehydrated for 2 days, and the chlorophyll fluorescence parameter Fv/Fm, which characterized the maximum photosynthetic potential, was inhibited. Comparatively, the leaf discs of Oreocharis cordatula shrunk slightly, and they maintained the Fv/Fm level, and had higher photoprotection ability [Y(NPQ)]. The leaf discs of both species spread out and Fv/Fm recovered following rewatered. After two days of dehydration, the relative water content (RWC) of the two species decreased to about 5%, the conductivity increased to 51.8% and 56.2%, respectively, and the content of soluble sugar content increased significantly. During the following rewatered, RWC, conductivity and soluble sugar all recovered to the control level. After further dehydration for 3 days, RWC of leaf discs of two species reached about 1.5%, the conductivity increased to about 95% after rehydration, and Fv/Fm disappeared. Chlorophyll a+b content of P. rufescens decreased by 50% during resuscitable dehydration and rehydration, while Oreocharis cordatula remained basically unchanged, which indicated that both of them were homoiochlorophyllous desiccation tolerance species and could quickly resume photosynthesis after rehydration following dehydration. During dehydration and rehydration, the contents of malonic dialdehyde (MDA) had no significant change, and remained extremely low level, which indicated two species could keep their membrane lipids from being oxidized under extreme drought conditions. To sum up, these two species can survive from dehydration to lower level of 5% RH, therefore they are both resurrection plants. Under severe dehydration，Paraboea rufescens can avoid the damage from excessive light absorption by curling its leaves; however, Oreocharis cordatula can spread the excessive energy by heat dissipation through photoprotection of PS II, thus protecting its photosynthesis organs.

Abstract： In this paper, the mycorrhizal infection rates of Bretschneidera sinensis under different water treatments (40%, 60%, 80%, 100%) and time points were determined. Quantified morphology characteristics of the seedlings such as heights, ground diameter, and number of leaves, together with malonaldehyde content and survival rate in the inoculation group and the control group before and after different water treatments were also determined. The results showed that, under the condition of relative soil moisture content of 60%, the infection rates of mycelium, arbuscula and the total were the highest, low moisture content (40%) and high moisture content (≥80%) were not conducive to mycorrhizal fungi on the seedlings infestation; the content of malondialdehyde in the inoculated seedlings was significantly lower than that of the control at 40% and 60% treatments, suggested that inoculation with Funneliformis mosseae could increase seedling resistance to drought stress, but with no obvious effect on treatments of 80% and 100% high moisture content; the relative water content of soil suitable for seedling growth under natural and inoculated conditions was 80% and 60%, respectively; under the same water conditions, the survival rate of inoculated seedlings was higher than that of the control, with the highest (90%) under 60% treatment, while the survival rate of seedlings was relatively low at 40% low moisture content and 100% saturated moisture content

Abstract： Abstract：The infection of a virus is a great threat to host; the innate immune system is set up as the natural protection system of an organism. VISA （also know as MAVS, CARDIF, IPS-1）, is an critical adapter protein required for virus-triggered IFN-β signaling, recruiting RIG-I-like receptors( including RIG-I and MDA5) and downstream signaling proteins to VISA signalosome at mitochondria upon virus infection, leading to activation of transcriptional factor IRF3 and NF-κB, and resulting in the induction of IFNs and other inflammatory cytokines. However, the mystery of VISA for the antiviral function is still not completely figured out. In this study, we use VISA as bait for screening a human 293T cell cDNA library in a yeast two-hybrid screening, trying to identify the interacting proteins of VISA. Then, coimmunoprecipitation experiments were carried out to verify the association between VISA and candidates proteins screened from the yeast two-hybrid system assay. It is indicated that Sec13L1 associated with VISA. Overexpression of Sec13L1 in 293 cells facilitated to enhance the activation of IFNβ promoter induced by VISA and virus infection in a dose-dependent manner.
