| 1 | Heterotic Group Classification of 63 Inbred Lines and Hybrid Purity Identification by Using SSR Markers in Winter Cabbage(Brassica Oleracea L. var. capitata)显示文摘Winter cabbage is an important crop cultivated through winter in the region near the Yangtze River, enabling the supply of fresh cabbage there at that time of year. However, a problem has emerged regarding the newly developed parents of winter cabbage, which is completely different from spring and autumn cabbage, namely, how to combine these parents to breed an elite hybrid. To classify the heterotic groups and improve the efficiency of parent selection in winter cabbage breeding, 20 polymorphic SSR markers were selected to screen 63 winter cabbage inbred lines. Seventeen pairs among the 20 SSR markers amplified polymorphic bands. These primers amplified two to six bands,with an average of 2.8 bands per primer, and a total of 47 polymorphic bands were generated in the 63 inbred lines. These lines included flatheaded morphotype and round-headed morphotype, thus they were separately classified into heterotic groups based on the SSR markers. The flat-headed morphotype contained 21 inbred lines and was classified into three heterotic groups, named Hanchun 4, Jiali, and Dongsheng, in accordance with the representative germplasm contained in each group. The round-headed morphotype contained 42 inbred lines and was classified into five heterotic groups, named Parte, Bejo1039, YK-143, SCA002, and Golden B90. Meanwhile, parent analysis of 20 developed elite combinations showed that their parents were all distributed in different heterotic groups, indicating that the group classification was reasonable,which can provide a basis for further parent selection in winter cabbage breeding. Furthermore, polymorphic SSR primers were successfully used to identify the hybrid purity of three elite varieties. | LI Xing YU Hailong LI Zhiyuan LIU Xiaoping FANG Zhiyuan LIU Yumei YANG Limei ZHUANG Mu LV Honghao ZHANG Yangyong | 2018 | Horticultural Plant Journal2018，4，4： | 11 |
| 2 | Utilization of Ogura CMS germplasm with the clubroot resistance gene by fertility restoration and cytoplasm replacement in Brassica oleracea L显示文摘Clubroot disease,a major plant root disease caused by Plasmodiophora brassicae,has become one of the most destructive diseases among cultivated cruciferous vegetables.However,clubroot-resistant Brassica oleracea materials are rare.A few clubroot-resistant cabbage varieties are available on the market,but all are Ogura cytoplasmic male sterile(CMS)types.Therefore,in this study,to reutilize the clubroot-resistant Ogura CMS germplasm of cabbage,a new fertility-restored Ogura CMS material,16Q2-11,was used as a bridge to transfer the clubroot resistance(CR)gene from the Ogura CMS cytoplasm to the normal cytoplasm by a two-step method(a fertility restoration and cytoplasm replacement method).In the first cross for fertility restoration of Ogura CMS clubroot-resistant cabbage(FRCRC),16Q2-11 was used as a restorer to cross with Ogura CMS materials containing the CR gene CRb2.Eleven Rfo-positive progenies were generated,of which four contained CRb2:F8-514,F8-620,F8-732 and F8-839.After inoculation with race 4 of P.brassicae,these four CRb2-positive individuals showed resistance.Furthermore,F8-514 and F8-839 were then used as male parents in the second cross of FRCRC to cross with cabbage inbred lines,resulting in the successful introgression of the CRb2 gene into the inbred lines.All offspring produced from this step of cross,which had a normal cytoplasm,showed a high resistance to race 4 of P.brassicae and could be utilized for the breeding of clubrootresistant cabbage varieties in the future.This is the first time that the Ogura CMS restorer has been used to restore the fertility of Ogura CMS clubroot-resistant cabbages,which could improve germplasm diversity in cabbage and provide a reference method for using CMS germplasm in Brassica crops. | Wenjing Ren Zhiyuan Li Fengqing Han Bin Zhang Xing Li Zhiyuan Fang Limei Yang Mu Zhuang Honghao Lv Yumei Liu Yong Wang Hailong Yu Yangyong Zhang | 2020 | Horticulture Research2020，7，1： | 7 |

| 8 | Dissection of two QTL clusters underlying yield-related heterosis in the cabbage founder parent 01–20显示文摘Cabbage has significant heterosis and most commercial cultivars are hybrids.To explore genetic basis of cabbage heterosis and promote cabbage heterosis utilization,we constructed two populations by crossing 100 DH lines derived from a cabbage hybrid 01–20×96–100 with two female parents.Hybrids exhibited different extents of heterosis,the mean value of economic yield was 2.6 times bigger than parents.We identified 66 and 73 QTLs associated with mid-parent heterosis and transgressive heterosis of twelve yield-related traits,respectively.Some QTLs could be detected under the two-year experiment existed in two populations with different testers,showing relatively high phenotypic contribution rate(15.8%–20.0%).Heterosis QTLs exhibited clustered distribution in several cabbage chromosome regions.Two dominant genetic regions,mk300–316 and mk258–268,originated from the elite parent 01–20,exhibited significant genetic effects for yield-related heterosis,which were first identified.Three elite DH lines(D22,D46,D83)harboring these two dominant regions were selected as having strong heterosis in cabbage production.Candidate gene analysis revealed that some genes participating in biosynthetic processes of carbohydrates and some responses to auxin might affect cabbage yield heterosis.QTL identification and genetic dissection of yield-related traits provide new insights into the genetic effects of cabbage heterosis. | Xing Li Honghao Lv Bin Zhang Zhiyuan Fang Limei Yang Mu Zhuang Yumei Liu Zhansheng Li Yong Wang Yangyong Zhang | 2023 | Horticultural Plant Journal2023，9，1： | 1 |

| 12 | Map-based cloning and CRISPR/Cas9-based editing uncover BoNA1 as the causal gene for the no-anthocyanin-accumulation phenotype in curly kale (Brassica oleracea var. sabellica)显示文摘Brassica oleracea comprises several important vegetable and ornamental crops,including curly kale,ornamental kale,cabbage,broccoli,and others.The accumulation of anthocyanins,important secondary metabolites valuable to human health,in these plants varies widely and is responsible for their pink to dark purple colors.Some curly kale varieties lack anthocyanins,making these plants completely green.The genetic basis of this trait is still unknown.We crossed the curly kale inbred line BK2019(without anthocyanins)with the cabbage inbred line YL1(with anthocyanins)and the Chinese kale inbred line TO1000(with anthocyanins)to generate segregating populations.The no-anthocyanin trait was genetically controlled by a recessive gene,bona1.We generated a linkage map and mapped bona1 to a 256-kb interval on C09.We identified one candidate gene,Bo9g058630,in the target genomic region;this gene is homologous to AT5G42800,which encodes a dihydroflavonol-4-reductase-like(DFR-like)protein in Arabidopsis.In BK2019,a 1-bp insertion was observed in the second exon of Bo9g058630 and directly produced a stop codon.To verify the candidate gene function,CRISPR/Cas9 gene editing technology was applied to knock out Bo9g058630.We generated three bona1 mutants,two of which were completely green with no anthocyanins,confirming that Bo9g058630 corresponds to BoNA1.Different insertion/deletion mutations in BoNA1 exons were found in all six of the other no-anthocyanin kale varieties examined,supporting that independent disruption of BoNA1 resulted in no-anthocyanin varieties of B.oleracea.This study improves the understanding of the regulation mechanism of anthocyanin accumulation in B.oleracea subspecies. | Kaiwen Yuan Xinyu Zhao Wenru Sun Limei Yang Yangyong Zhang Yong Wang Jialei Ji Fengqing Han Zhiyuan Fang Honghao Lv | 2023 | Horticulture Research2023，10，8： | 0 |
| 13 | Genetic diversity and population structure analysis of 161 broccoli cultivars based on SNP markers显示文摘To better understand the genetic diversity and population structure of broccoli cultivars planted in China,a total of 161 representative broccoli cultivars in the past 25 years were collected and analysed based on single nucleotide polymorphism(SNP)markers.Ten pairs of primers with good polymorphism and high resolution were screened from 315 pairs of SNP primers by 3 broccoli accessions(inbred lines)with different phenotypes and maturity.The 10 pairs of SNP primers were selected,producing 78 alleles.The diversity analysis indicated that the polymorphism information content(PIC)of SNP primer ranged from 0.64 to 0.90.The observed number of alleles(Na)was 2.00,the effective number of alleles(Ne)was 1.11–2.00,the Nei’s gene diversity(H)was 0.10–0.50,and Shannon information index(I)was 0.20–0.70 using PopGene32 software.The clustering results showed that the 161 broccoli cultivars could be divided into 4 major subgroups(A,B,C and D),foreign cultivars were all assigned to subgroup A,and domestic cultivars were assigned to 3 subgroups of B,C,and D.This study indicated that some domestic cultivars and foreign cultivars were similar in genetic background,but most domestic cultivars were still different from the Japanese cultivars.When K=2,the population structure result presented that 161 broccoli cultivars could be divided into 1 simple group(2 groups)and 1 mixed group.When Q≥0.6,143(88.82%)broccoli cultivars belonged to the simple groups.In simple groups 68(42.24%)broccoli cultivars of group 1 were derived from Japan,the United States,Switzerland,the Netherlands,China-Taiwan,and China-Mainland;75(46.58%)broccoli cultivars belonged to group 2;when Q<0.6,18(11.18%)broccoli cultivars belonged to the mixed groups.This study is helpful to understand the diversity and resolution of broccoli cultivars from worldwide,which is beneficial to plant breeding and materials innovation.And meanwhile,this result is also used for construction of broccoli fingerprint serving for cultivar identification. | Jingjing Huang Yumei Liu Fengqing Han Zhiyuan Fang Limei Yang Mu Zhuang Yangyong Zhang Honghao Lv Yong Wang Jialei Ji Zhansheng Li | 2021 | Horticultural Plant Journal2021，7，5： | 0 |
| 14 | Genome-wide identification and analysis of cytokinin dehydrogenase/oxidase(CKX) family genes in Brassica oleracea L.reveals their involvement in response to Plasmodiophora brassicae infections显示文摘Cytokinins are a class of phytohormones that promote cell division and differentiation and are thought to affect plant immunity to multiple pathogens.However,a comprehensive analysis of cytokinin dehydrogenase/oxidase(CKX)family genes in cabbage has not been reported.In this study,a total of 36 CKX genes were identified using a genome-wide search method.Phylogenetic analysis classified these genes into three groups.They were distributed unevenly across nine chromosomes in B.oleracea,and 15 of them did not contain any introns.The results of colinearity analysis showed that 36 CKX gene in Arabidopsis was present in several copies in the Brassica oleracea genome.An analysis of cisacting elements indicated that all genes possessed at least one stress or hormone responsive cis-acting element.A heatmap of CKX gene expression showed the patterns of expression of these genes in various tissues and organs.Three genes(Bol028363,Bol031036 and Bol018140)were relatively highly expressed in all of the investigated tissues under normal conditions,showing the expression profile of housekeeping genes.Generally,the expression patterns of CKX genes in Jingfeng 1 and Xiangan 336 were quite different under the same treatment.Notably,three genes(Bol020547,Bol028392 and Bol045724)were significantly down-regulated and up-regulated in the susceptible and resistant material,respectively,after inoculation,which may indicate their crucial roles in resistance to clubroot disease.The results provide insights for better understanding the roles of CKX genes in the B.oleracea–P.brassicae interaction. | Mingzhao Zhu Yong Wang Shujin Lu Limei Yang Mu Zhuang Yangyong Zhang Honghao Lv Zhiyuan Fang Xilin Hou | 2022 | Horticultural Plant Journal2022，8，1： | 0 |
