| 1 | Transcriptome profiles reveal that gibberellin-related genes regulate weeping traits in crape myrtle显示文摘Plant architecture includes vital traits that influence and benefit crops,and economically important trees.Different plant architectures provide natural beauty.Weeping ornamental plants are aesthetically appealing to people.The regulatory mechanism controlling the weeping trait is poorly understood in crape myrtle.To investigate the weeping trait mechanism,transcriptional profiling of different organs in weeping and upright crape myrtle was performed based on phenotype.Phenotypic and histological analyses demonstrated that endodermal cells were absent,and that new shoot phenotypes could be rescued by the GA3 treatment of weeping plants.The transcriptional analysis and coexpression network analysis(WGCNA)of differentially expressed genes indicated that GA synthesis and signal transduction pathways play a role in weeping traits.When the expression level of a negative element of GA signaling,LfiGRAS1,was reduced by virus-induced gene silencing(VIGS),new branches grew in infected plants in a negatively geotropic manner.An integrated analysis implied that GA had a strong influence on weeping crape myrtle by interacting with other factors.This study helps to elucidate the mechanism governing the weeping trait and can improve the efficiency of breeding in Lagerstroemia. | Suzhen Li Tangchun Zheng Xiaokang Zhuo Zhuojiao Li Lulu Li Ping Li Like Qiu Huitang Pan Jia Wang Tangren Cheng Qixiang Zhang | 2020 | Horticulture Research2020，7，1： | 5 |
| 2 | Establishment and Verification of An Efficient Virus-induced Gene Silencing System in Forsythia显示文摘To understand the functional identification of large-scale genomic sequences in Forsythia,tobacco rattle virus(TRV)-mediated virus-induced gene silencing(VIGS),suitable for the plant,was explored in this study.The results showed that the TRV-mediated VIGS system could be successfully used in Forsythia for silencing the reporter gene FsPDS(Forsythia phytoene desaturase)using stem infiltration and leaf infiltrationmethods.All the treated plants were pruned below the injection site after 7–15 d infection;the FsPDS was silenced and typical photobleaching symptoms were observed in newly sprouted leaves at the whole-plant level.Meanwhile,this system has been successfully tested and verified through virus detection and qRT-PCR analysis.After the optimization,Forsythia magnesium chelatase subunit H(FsChlH)was silenced successfully in Forsythia using this system,resulting in yellow leaveswith decreased chlorophyll content.The system was stable,highly efficient and had greater rapidity and convenience,which made it suitable to study the function of genes related to physiological pathways such as growth and development,and metabolic regulation in Forsythia. | Jianshuang Shen Weijia Si Yutong Wu Yang Xu Jia Wang Tangren Cheng Qixiang Zhang Huitang Pan | 2021 | Horticultural Plant Journal2021，7，1： | 3 |

| 4 | Genome assembly and resequencing analyses provide new insights into the evolution, domestication and ornamental traits of crape myrtle显示文摘Crape myrtle(Lagerstroemia indica)is a globally used ornamental woody plant and is the representative species of Lagerstroemia.However,studies on the evolution and genomic breeding of L.indica have been hindered by the lack of a reference genome.Here we assembled the first high-quality genome of L.indica using PacBio combined with Hi-C scaffolding to anchor the 329.14-Mb genome assembly into 24 pseudochromosomes.We detected a previously undescribed independent whole-genome triplication event occurring 35.5 million years ago in L.indica following its divergence from Punica granatum.After resequencing 73 accessions of Lagerstroemia,the main parents of modern crape myrtle cultivars were found to be L.indica and L.fauriei.During the process of domestication,genetic diversity tended to decrease in many plants,but this was not observed in L.indica.We constructed a high-density genetic linkage map with an average map distance of 0.33 cM.Furthermore,we integrated the results of quantitative trait locus(QTL)using genetic mapping and bulk segregant analysis(BSA),revealing that the major-effect interval controlling internode length(IL)is located on chr1,which contains CDL15,CRG98,and GID1b1 associated with the phytohormone pathways.Analysis of gene expression of the red,purple,and white flower-colour flavonoid pathways revealed that differential expression of multiple genes determined the flower colour of L.indica,with white flowers having the lowest gene expression.In addition,BSA of purple-and green-leaved individuals of populations of L.indica was performed,and the leaf colour loci were mapped to chr12 and chr17.Within these intervals,we identified MYB35,NCED,and KAS1.Our genome assembly provided a foundation for investigating the evolution,population structure,and differentiation of Myrtaceae species and accelerating the molecular breeding of L.indica. | Yang Zhou Tangchun Zheng Ming Cai Lu Feng Xiufeng Chi Ping Shen Xin Wang Zhiting Wan Cunquan Yuan Man Zhang Yu Han Jia Wang Huitang Pan Tangren Cheng Qixiang Zhang | 2023 | Horticulture Research2023，10，9： | 1 |
