| 1 | Functional analysis of a novel C-glycosyltransferase in the orchid Dendrobium catenatum显示文摘Flavonoids,which are a diverse class of phytonutrients,are used by organisms to respond to nearly all abiotic stresses and are beneficial for human health.Glycosyltransferase,used during the last step of flavonoid biosynthesis,is important in flavonoid enrichment.However,little is known about glycosyltransferase in the orchid Dendrobium catenatum(D.officinale).In this study,we isolated a novel C-glycosyltransferase(designated DcaCGT)from the orchid D.catenatum by identifying and analyzing 82 putative genes in the GT1 family.DcaCGT could specifically catalyze not only di-C-glycosylation but also O-glycosylation.Apart from the normal function of catalyzing 2-hydroxynaringenin and phloretin to the respective di-C-glycosides,DcaCGT also catalyzes apigenin to cosmosiin.Targeted metabolic profiling of the substrates(2-hydroxynaringenin,phloretin,and apigenin)and products(vitexin,isovitexin,vicenin-2,nothofagin,3’,5’-di-C-glucosylphloretin,and cosmosiin)in different tissues showed that vicenin-2 was the most abundant product of this novel enzyme.Cosmosiin was detected in flowers and flower buds.We also established that DcaCGT functions expanded throughout the evolution of D.catenatum.Residual OGT activity may help D.catenatum resist drought stress.Our study illustrates the function,origin,and differentiation of DcaCGT and provides insights into glycosylation and molecular propagation processes,which can be used to improve the production of flavonoids by the cultivated medicinal plant D.catenatum. | Zhiyao Ren Xiaoyu Ji Zhenbin Jiao Yingyi Luo Guo-Qiang Zhang Shengchang Tao Zhouxi Lei Jing Zhang Yuchen Wang Zhong-Jian Liu Gang Wei | 2020 | Horticulture Research2020,7,1: | 5 |

| 5 | Delay performance of the CFDAMA-RPR protocol via satellite显示文摘The relative performance of the combined free/demand assignment multiple access (CFDAMA) protocol with different terminal request strategies is examined. A new scheme is proposed employing combined round robin/ piggybacking request strategy (CFDAMA-RPR), which is compared with the CFDAMA-RR (employing round robin request strategy) and CFDAMA-PB (employing piggy-backing request strategy). Simulation results demonstrate that compared with CFDAMA-PB and CFDAMA-RR protocol, the CFDAMA-RPR scheme can offer better delay/throughput performance of satellite channel. | ZhouXi JiaShilou SheYang | 2004 | Journal of Systems Engineering and Electronics2004,15,4: | 1 |

| 14 | Comparative Studies on Sperm Ultrastructure of Three Gecko Species, Gekko japonicus, Gekko chinensis and Hemidactylus bowrigii(Reptilia, Squamata, Gekkonidae)显示文摘We provide the first description of the ultrastructure of the spermatozoa of Gekko japonicus, Gekko chinensis and Hemidactylus bowrigii for further understanding of the phylogenetic relationships of Gekkonidae. Mature spermatozoa of the three species differ in the occurrence and shape of epinuclear electron-lucent zone, nuclear space, neck cylinder and mitochondria. G. japonicus and G. chinensis have similar spermatozoan ultrastructure while H. bowrigii differs from these two species. In addition, these three species have neck cylinder with mitochondria in neck region and dense bodies arranged in grid with mitochondria in the midpiece, which may be the autapomorphies of the family Gekkonidae. Statistical analyses reveal that: total length of the spermatozoa was significantly different between G. japonicus and G. chinensis, as well as between G. japonicus and H. bowrigii(F2,57 = 23.66, P < 0.0001); G. japonicus and H. bowrigii differ in head length(F2,43 = 4.64, P < 0.05) and the width of nuclear base(F2,22 = 3.97, P <0.05). In addition, the midpiece length(F2,33 = 23.66, P < 0.01) of the spermatozoa was significantly different between H. bowrigii and G. japonicus, and also between H. bowrigii and G. chinensis. Lengths of perforatorium, acrosomal complex and nuclear rostrum and the width of nuclear shoulder are similar in all three species. Our results indicated that the sperm ultrastructure contained intra and intergeneric variabilities which is helpful for better understanding their genetic relationships. | Shuangli HAO Liangliang PAN Zhouxi FANG Yongpu ZHANG | 2015 | Asian Herpetological Research2015,6,3: | 0 |
