| 6 | Ectopic expression of a male fertility gene,LOGL8,represses LOG and hinders panicle and ovule development显示文摘Grain number and seed-setting rate are components of crop yield.Cytokinin influences grain yield.However,emerging studies suggest that high cytokinin signals often lead to reduced branching or seed-setting rate,leading to reduced grain yield,although the mechanisms remain unclear.In this study,we identified and characterized the rice(Oryza sativa L.)gene LONELY GUY-LIKE 8(LOGL8),based on analysis of the LOGL8-pm(promoter mutant of LOGL8)mutant,which harbors a T-DNA insertion in the promoter of this gene.The mutation in LOGL8-pm causes ectopic hyperexpression of LOGL8 in inflorescence organs,resulting in plants with smaller panicles and defective ovules lacking archesporial cells and integuments.Knockout of LOGL8 caused pollen abortion,leading to a reduced seed-setting rate.LOGL8 encodes a putative cytokinin-activating enzyme.Our results showed that LOGL8 directly catalyzes the biosynthesis of bioactive cytokinins.Therefore,we propose that the ectopic expression of LOGL8 disrupts cytokinin spatiotemporal distribution and causes inhibition of LONELY GUY(LOG),which affects panicle branching and female organ development.These findings reveal the important role of LOGL8 in male development,and highlight the delicate balance of local cytokinin levels during panicle branching and female organ development. | Shuifu Chen Sulin Lou Xiucai Zhao Shijuan Zhang Letian Chen Ping Huang Guande Li Yingying Li Yao-Guang Liu Yuanling Chen | 2022 | The Crop Journal2022，10，6： | 0 |
| 7 | AN EFFICIENT RADIO RESOURCE MANAGEMENT STRATEGY FOR ADAPTIVE OFDM CELLULAR SYSTEMS显示文摘This paper presents an efficient Radio Resource Management (RRM) strategy for adaptive Orthogo-nal Frequency Division Multiplexing (OFDM) cellular systems. In the proposed strategy, only those users who have the same distance from their base stations can reuse a same subcarrier. This can guarantee the received Carrier-to-Interference ratio (C/I) of each subcarrier to be acceptable as required by system planning. Then by employing different modulation scheme on each subcarrier according to its received C/I, system spectral effi-ciency can be gracefully increased. Analytical and simulation results show that the spectral efficiency is im-proved by 40% without sacrificing the Bit Error Rate (BER) performance and call blocking probability and sys-tem capacity of the proposed strategy is better than conventional systems. | Yu Guanding Zhang Zhaoyang Qiu Peiliang | 2006 | Journal of Electronics(China)2006，23，4： | 0 |
| 8 | COOPERATIVE ARQ PROTOCOL FOR CORRELATED WIRELESS CHANNELS显示文摘A novel Automatic repeat ReQuest (ARQ) protocol called cooperative ARQ is presented in this let-ter, where a relay terminal is requested to retransmit an erroneously received packet, instead of the source ter-minal. The data link layer Packet Error Rate (PER) performance of cooperative ARQ is derived in correlated wireless channel. The results show that even though the relay-destination channel is worse than the source-destination channel, the new protocol outperforms the traditional one as long as the average SNR of the relay-destination channel is better than a certain threshold. It is also demonstrated that a second order diversity gain can be achieved with the cooperative ARQ protocol. | Yu Guanding Zhang Zhaoyang Qiu Peiliang | 2006 | Journal of Electronics(China)2006，23，4： | 0 |
