| 1 | Hydrate agglomeration modeling and pipeline hydrate slurry flow behavior simulation显示文摘Dynamic modeling and numerical simulation of hydrate slurry flow behavior are of great importance to offshore hydrate management.For this purpose, a dynamic model of hydrate agglomeration was proposed in this paper.Based on population balance equation, the frame of the dynamic model was established first, which took both hydrate agglomeration and hydrate breakage into consideration.Then, the calculating methods of four key parameters involved in the dynamic model were given according to hydrate agglomeration dynamics.The four key parameters are collision frequency, agglomeration efficiency, breakage frequency and the size distribution of sub particles resulting from particle breakage.After the whole dynamic model was built, it was combined with several traditional solid–liquid flow models and then together solved by the CFD software FLUENT 14.5.Finally, using this method, the influences of flow rate and hydrate volume fraction on hydrate particle size distribution, hydrate volume concentration distribution and pipeline pressure drop were simulated and analyzed. | Guangchun Song Yuxing Li Wuchang Wang Kai Jiang Zhengzhuo Shi Shupeng Yao | 2019 | Chinese Journal of Chemical Engineering2019，27，1： | 6 |

| 3 | Inter-species mRNA transfer among green peach aphids,dodder parasites,and cucumber host plants显示文摘mRNAs are transported within a plant through phloem.Aphids are phloem feeders and dodders(Cuscuta spp.)are parasites which establish phloem connections with host plants.When aphids feed on dodders,whether there is trafficking of mRNAs among aphids,dodders,and host plants and if aphid feeding a匚fects the mRNA transfer between dodders and hosts are unclear.We constructed a green peach aphid(GPA,Myzus persicae)-dodder(Cuscuta austra/is)-cucumber(Cucumis sativus)tritrophic system by infesting GPAs on C.australis,which parasitized cucumber hosts.We found that GPA feeding activated defense-related phytohormonal and transcriptomic responses in both C.australis and cucumbers and large numbers of mRNAs were found to be transferred between C.australis and cucumbers and between C.australis and GPAs;importantly,GPA feeding on C.australis greatly altered inter-species mobile mRNA profiles.Furthermore,three cucumber mRNAs and three GPA mRNAs could be respectively detected in GPAs and cucumbers.Moreover,our statistical analysis indicated that mRNAs with high abundances and long transcript lengths are likely to be mobile.This study reveals the existence of inter-species and even inter-kingdom mRNA movement among insects,parasitic plants,and parasite hosts,and suggests complex regulation of mRNA trafficking. | Juan Song Jinge Bian Na Xue Yuxing Xu Jianqiang Wu | 2022 | Plant Diversity2022，44，1： | 1 |

| 5 | Investigation on hydrate growth at the oil–water interface:In the presence of asphaltene显示文摘Natural gas hydrates can readily form in deep-water oil production processes and pose a great threat to the oil industry.Moreover,the coexistence of hydrate and asphaltene can result in more severe challenges to subsea flow assurance.In order to study the effects of asphaltene on hydrate growth at the oil-water interface,a series of micro-experiments were conducted in a self-made reactor,where hydrates nucleated and grew on the surface of a water droplet immersed in asphaltene-containing oil.Based on the micro-observations,the shape and growth rate of the hydrate shell formed at the oil-water interface were mainly investigated and the effects of asphaltene on hydrate growth were analyzed.According to the experimental results,the shape of the water droplet and the interfacial area changed significantly after the formation of the hydrate shell when the asphaltene concentration was higher than a certain value.A mechanism related to the reduction of the interfacial tension caused by the absorption of asphaltenes on the interface was proposed for illustration.Moreover,the growth rate of the hydrate shell decreased significantly with the increasing asphaltene concentration under experimental conditions.The conclusions of this paper could provide preliminary insight how asphaltene affect hydrate growth at the oil-water interface. | Guangchun Song Yuanxing Ning Yuxing Li Wuchang Wang | 2022 | Chinese Journal of Chemical Engineering2022，35，5： | 1 |
| 6 | ZmMYC2s play important roles in maize responses to simulated herbivory and jasmonate显示文摘Both herbivory and jasmonic acid(JA)activate the biosynthesis of defensive metabolites in maize,but the mechanism underlying this remains unclear.We generated maize mutants in which ZmMYC2a and ZmMYC2b,two transcription factor genes important in JA signaling,were individually or both knocked out.Genetic and biochemical analyses were used to elucidate the functions of ZmMYC2 proteins in the maize response to simulated herbivory and JA.Compared with the wild-type(WT)maize,the double mutant myc2ab was highly susceptible to insects,and the levels of benzoxazinoids and volatile terpenes,and the levels of their biosynthesis gene transcripts,were much lower in the mutants than in the WT maize after simulated insect feeding or JA treatment.Moreover,ZmMYC2a and ZmMYC2b played a redundant role in maize resistance to insects and JA signaling.Transcriptome and Cleavage Under Targets and TagmentationSequencing(CUT&Tag-Seq)analysis indicated that ZmMYC2s physically targeted 60%of the JAresponsive genes,even though only 33%of these genes were transcriptionally ZmMYC2-dependent.Importantly,CUT&Tag-Seq and dual luciferase assays revealed that ZmMYC2s transactivate the benzoxazinoid and volatile terpene biosynthesis genes IGPS1/3,BX10/11/12/14,and TPS10/2/3/4/5/8 by directly binding to their promoters.Furthermore,several transcription factors physically targeted by ZmMYC2s were identified,and these are likely to function in the regulation of benzoxazinoid biosynthesis.This work reveals the transcriptional regulatory landscapes of both JA signaling and ZmMYC2s in maize and provides comprehensive mechanistic insight into how JA signaling modulates defenses in maize responses to herbivory through ZmMYC2s. | Canrong Ma Ruoyue Li Yan Sun Mou Zhang Sen Li Yuxing Xu Juan Song Jing Li Jinfeng Qi Lei Wang Jianqiang Wu | 2023 | Journal of Integrative Plant Biology2023，65，4： | 0 |
