| 1 | Research on the Synchronization of Modulation Hopping System:I Synchronization Scheme显示文摘In order to achieve fast synchronization of the modulation hopping system, a synchronization scheme called short code to guide long code is adopted, and the initial synchronization hops and service hops are designed in detail.According to the system requirements for short code in the properties of time-varying, safety and balance, an algorithm to design wide-gap chaos short code based on TOD is proposed.Synchronization performance analysis shows that the algorithm has good performance, the initial synchronization time and the later entering network synchronization time are short, additionally, maximum synchronization time difference and synchronization maintaining time are long, all of which meet the needs of normal communications, and further verify the synchronization scheme feasible. | Tai Nengjian Wu Dewei Wu Jie Li Ting | 2009 | China Communications2009，6，4： | 2 |
| 2 | Rice Blast Resistance-associated Genes Based on Different RNA-seq Resources显示文摘Rice is the main food crop in Asian countries, and rice blast causes an annual loss of rice yield of 30%-35%. Cultivating rice blast resistant varieties and discovering resistance genes are important means to prevent rice blast. By analyzing the changes in rice transcriptome expression levels before and after infection by Magnaporthe oryzae of different physiological races, we found that 5 transcripts were up-regulated together after infection, Os07 t0125500-01, Os07 t0129300-00, Os07 t0126301-01 and Os07 t0124900-01 belongs to the CAP superfamily, and Os10 t0409400-01 encodes a BURP domain containing protein. | Tao ZHOU Yalong ZHANG Dewei TAI Xiaozhong ZHANG Xueshi LIU Wei ZHANG | 2021 | Agricultural Biotechnology2021，10，6： | 0 |
| 3 | High Temperature-preventing Cultivation Technology of Single-season Middle Rice for High Yield and High Quality in Jianghuai Area显示文摘In recent years,with the global climate change,the frequency and duration of high temperature in summer and autumn have increased,causing high temperature heat damage to summer crops such as rice and maize.From the end of July to early August is the main period of high temperature occurrence,during which the daily average temperature above 30℃is a high probability event,and even the highest temperature is above 38℃,while this period coincides with the booting-blooming-filling stage of the single-season middle rice in Jianghuai,especially the middle-season indica rice,so it often leads to the degradation of rice spikelets,pollen abortion,difficulty in pollen dispersion,and even difficulty in heading,resulting in a serious decline in the seed setting rate and poor filling of grains,which finally affect the yield and quality.Based on the goal of high-yielding high-quality rice cultivation,this paper proposed targeted technical measures for single-season middle rice from the aspects of planting time sequence optimization,selection of high-temperature-resistant varieties,population construction,fertilizer and water management technology,and how to compensate for the occurrence of unexpected disasters to promote plant growth.This study provides technical support for high-yielding high-quality stress-resistant and disaster-reducing rice cultivation technology. | Dewen ZHANG Wei ZHANG Youzun XU Wanlin WANG Dewei TAI Xiaozhong ZHANG Xueyuan SUN | 2022 | Agricultural Biotechnology2022，11，2： | 0 |
| 4 | An epi-allele of SMS causes Sanming dominant genic male sterility in rice显示文摘Male sterility is an important trait in rice for hybrid rice(Oryza sativa)breeding.However,the factors involved in dominant male sterility are largely unknown.Here,we identified a gene from Sanming dominant genic male sterile rice,named Sanming dominant male sterility(SMS),and reported that an epi-allele of this locus contributes to male sterility.Segregation analysis attributed dominant male sterility to a single locus,SMS,which we characterized using a male-sterile near isogenic line(NIL)of rice cultivar 93-11.The SMS locus was heterozygous in the male-sterile 93-11 NIL,containing an epi-allele identical to that in 93-11,and an epi-allele identical to that in rice cultivar Nipponbare,which we refer to as SMS9 and SMSN,respectively.SMS9is silent and hyper-methylated,whereas SMSNis expressed and hypo-methylated in the 93-11 NIL.Overexpressing SMSNled to male sterility.Mutations in SMS rescued the male sterility of the 93-11 NIL.Interestingly,we observed the duplication of SMSN in Nipponbare,but did not observe the duplication of SMS9in 93-11.Together,these findings suggest that the reduced methylation and enhanced expression of the SMSNepi-allele in the 93-11 NIL is responsible for its role in conferring dominant male sterility. | Yachun Yang Cheng Zhang Hao Li Zeyuan Yang Zuntao Xu Dewei Tai Dahu Ni Pengcheng Wei Chengxin Yi Jianbo Yang Yong Ding | 2023 | Science China(Life Sciences)2023，66，12： | 0 |
