1Generation of new glutinous rice by CRISPR/Cas9-targeted mutagenesis of the Waxy gene in elite rice varieties显示文摘In rice, amylose content(AC) is controlled by a single dominant Waxy gene. We used Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/CRISPR-associated 9(Cas_9) to introduce a loss-of-function mutation into the Waxy gene in two widely cultivated elite japonica varieties. Our results show that mutations in the Waxy gene reduce AC and convert the rice into glutinous ones without affecting other desirable agronomic traits, offering an effective and easy strategy to improve glutinosity in elite varieties. Importantly, we successfully removed the transgenes from the progeny. Our study provides an example of generating improved crops with potential for commercialization, by editing a gene of interest directly in elite crop varieties.Jinshan Zhang Hui Zhang Jose Ramón Botella Jian-Kang Zhu 2018Journal of Integrative Plant Biology2018,60,5:49

3Perspectives on the Application of Genome-Editing Technologies in Crop Breeding显示文摘Most conventional and modern crop-improvement methods exploit natural or artificially induced genetic variations and require laborious characterization of the progenies of multiple generations derived from time-consuming genetic crosses.Genome-editing systems,in contrast,provide the means to rapidly modify genomes in a precise and predictable way,making it possible to introduce improvements directly into elite varieties.Here,we describe the range of applications available to agricultural researchers using existing genome-editing tools.In addition to providing examples of genome-editing applications in crop breeding,we discuss the technical and social challenges faced by breeders using genome-editing tools for crop improvement.Kai Hua Jinshan Zhang Jose Ramon Botella Changle Ma Fanjiang Kong Baohui Liu Jian-Kang Zhu 2019Molecular Plant2019,12,8:19
4A detailed procedure for CRISPR/Cas9-mediated gene editing in Arabidopsis thaliana显示文摘The newly developed CRISPR(Clustered Regularly Interspaced Short Palindromic Repeats)/Cas(CRISPR-associated) system has emerged as an efficient tool for genome-editing, providing an alternative to classical mutagenesis and transgenic methods to study gene function and improve crop traits. CRISPR/Cas facilitates targeted gene editing through RNA-guided DNA cleavage followed by cellular DNA repair mechanisms that introduce sequence changes at the site of cleavage. Here we describe a detailed procedure for our previously developed and highly efficient CRISPR/Cas9 method that allows the generation of heritable-targeted gene mutations andcorrections in Arabidopsis. This protocol describes the strategies and steps for the selection of targets, design of single-guide RNA(sg RNA), vector construction and analysis of transgenic lines. We also offer a method to target two loci simultaneously using vectors containing two different sg RNAs. The principles described in this protocol can be applied to other plant species to generate stably inherited DNA modifications.Wenshan Liu Xiaohong Zhu Mingguang Lei Qingyou Xia Jose Ramon Botella Jian-Kang Zhu Yanfei Mao 2015Science Bulletin2015,60,15:18
5Gene editing in plants:progress and challenges显示文摘The clustered regularly interspaced short palindromic repeat(CRISPR)-associated protein 9(Cas9)genome editing system is a powerful tool for targeted gene modifications in a wide range of species,including plants.Over the last few years,this system has revolutionized the way scientists perform genetic studies and crop breeding,due to its simplicity,flexibility,consistency and high efficiency.Considerable progress has been made in optimizing CRISPR/Cas9 systems in plants,particularly for targeted gene mutagenesis.However,there are still a number of important challenges ahead,including methods for the efficient delivery of CRISPR and other editing tools to most plants,and more effective strategies for sequence knock-ins and replacements.We provide our viewpoint on the goals,potential concerns and future challenges for the development and application of plant genome editing tools.Yanfei Mao Jose Ramon Botella Yaoguang Liu Jian-Kang Zhu 2019National Science Review2019,6,3:17

8Multicell power allocation method based on game theory for inter-cell interference coordination显示文摘As a new technology, coordinated multipoint (CoMP) transmission is included in LTE-Advanced study item. Moreover, the network architecture in LTE-Advanced system is modified to take into account coordinated transmission. Under this background, a novel power allocation game model is established to mitigate inter-cell interference with cellular coordination. In the light of cellular cooperation relationship and centralized control in eNodeB, the power allocation in each served antenna unit aims to make signal to interference plus noise ratio (SINR) balanced among inter-cells. Through the proposed power allocation game algorithm, the users' SINR can reach the Nash equilibrium, making it feasible to reduce the co-frequency interference by decreasing the transmitted power. Numerical results show that the proposed power allocation algorithm improves the throughput both in cell-center and cell-edge. Moreover, the blocking rate in cell-edge is reduced too.ZHANG Hui XU XiaoDong LI JingYa TAO XiaoFeng ZHANG Ping SVENSSON Tommy BOTELLA Carmen 2009Science in China(Series F)2009,52,12:5
9Genome editing for plant research and crop improvement显示文摘The advent of clustered regularly interspaced short palindromic repeat(CRISPR) has had a profound impact on plant biology, and crop improvement. In this review, we summarize the state-of-the-art development of CRISPR technologies and their applications in plants, from the initial introduction of random small indel(insertion or deletion) mutations at target genomic loci to precision editing such as base editing, prime editing and gene targeting. We describe advances in the use of class 2, types II, V, and VI systems for gene disruption as well as for precise sequence alterations, gene transcription, and epigenome control.Xiangqiang Zhan Yuming Lu Jian-Kang Zhu Jose Ramon Botella 2021Journal of Integrative Plant Biology2021,63,1:5
10Performance of power control in inter-cell interference coordination for frequency reuse显示文摘To mitigate inter-cell interference in 3G evolution systems,a novel inter-cell interference coordination scheme called soft fractional frequency reuse is proposed in this article,which enables to improve the data rate in cell-edge.On this basis,an inter-cell power control is presented for the inter-cell interference coordination,and the inter-cell balanced signal to interference plus noise ratio(SINR) among users is established for power allocation,which enables mitigation of inter-cell interference.Especially,the power control is based on a novel exponential kernel equation at higher convergence speed than the traditional arithmetic kernel equations.Numerical results show that the proposed scheme improves the throughput and reduces the blocking rate compared to the existing power control algorithms.ZHANG Hui XU Xiao-dong LI Jing-ya TAO Xiao-feng Tommy Svensson Carmen Botella 2010The Journal of China Universities of Posts and Telecommunications2010,17,1:2
