| 1 | Genome of Wild Mandarin and Domestication History of Mandarin显示文摘官员(柠檬 reticulata ) 是世界范围的最重要的柠檬庄稼之一。它的驯服被相信发生在华南,它是四几千年的官员耕作的中心之一。我们在 Nanling 区域附近收集了官员的自然野人口并且在附近栽培了 landraces。我们发现柠檬性的酸水平戏剧性地在栽培官员被减少。理解 ? 官员驯服的基因基础,我们 de novo 装配了野官员的一个草稿染色体并且分析了一套 104 个柠檬染色体。我们发现 Mangshan 官员是一种原始类型并且二个独立驯服事件发生了,分别地导致在北方和南方 Nanling 山的二组栽培官员(MD1 和 MD2 ) 。二个瓶颈和有效人口尺寸的二扩大为栽培官员的 MD1 组被识别。然而,在 MD2 组织 ? 在人口尺寸有长、连续的减少。MD1 和 MD2 官员从栽培 pummelo 种类显示出种间的基因渗入的不同模式。我们在官员的驯服期间在选择下面可能在基因在柠檬酸盐内容的规定包含了的 aconitate hydratase (ACO ) 识别了高分叉的一个区域,它是。这研究为现存野官员人口的地理起源提供具体基因证据并且使驯服和官员的进化历史清楚些。 | Lun Wang Fa He Yue Huang Jiaxian He Shuizhi Yang Jiwu Zeng Chongling Deng Xiaolin Jiang Yiwen Fang Shaohua Wen Rangwei Xu Huiwen Yu Xiaoming Yang Guangyan Zhong Chuanwu Chen Xiang Yan Changfu Zhou Hongyan Zhang Zongzhou Xie Robert M.

| 2 | Quantitative trait locus mapping of yield and plant height in autotetraploid alfalfa(Medicago sativa L.)显示文摘Alfalfa(Medicago sativa L.)is the most widely grown forage legume crop worldwide.Yield and plant height are important agronomic traits influenced by genetic and environmental factors.The objective of this study was to identify quantitative trait loci(QTL)and molecular markers associated with alfalfa yield and plant height.To understand the genetic basis of these traits,a full-sib F1 population composed of 392 individuals was developed by crossing a low-yielding precocious alfalfa genotype(male parent)with a high-yielding latematuring alfalfa cultivar(female parent).The linkage maps were constructed with 3818 single-nucleotide polymorphism(SNP)markers on 64 linkage groups.QTL for yield and plant height were mapped using phenotypic data for three years.Sixteen QTL associated with yield and plant height were identified on chromosomes 1 to 8.Six QTL explained more than 10%of phenotypic variation,representing major loci controlling yield and plant height.One locus on chromosome 1 controlling yield traits had not been identified in previous studies.Three QTL co-located with other QTL(qyield-1 and qheight-7,qheight-5 and qyield-4,qheight-6,and qyield-6).With further validation,the markers closely linked with these QTL may be used for marker-assisted selection in breeding new alfalfa varieties with high yield. | Fei He Ruicai Long Tiejun Zhang Fan Zhang Zhen Wang Xijiang Yang Xueqian Jiang Changfu Yang Xuxin Zhi Mingna Li Longxi Yu Junmei Kang Qingchuan Yang | 2020 | The Crop Journal2020，8，5： | 1 |
| 3 | Genome Assembly of Alfalfa Cultivar Zhongmu-4 and Identification of SNPs Associated with Agronomic Traits显示文摘Alfalfa(Medicago sativa L.)is the most important legume forage crop worldwide with high nutritional value and yield.For a long time,the breeding of alfalfa was hampered by lacking reliable information on the autotetraploid genome and molecular markers linked to important agronomic traits.We herein reported the de novo assembly of the allele-aware chromosome-level genome of Zhongmu-4,a cultivar widely cultivated in China,and a comprehensive database of genomic variations based on resequencing of 220 germplasms.Approximate 2.74 Gb contigs(N50 of 2.06 Mb),accounting for 88.39%of the estimated genome,were assembled,and 2.56 Gb contigs were anchored to 32 pseudo-chromosomes.A total of 34,922 allelic genes were identified from the allele-aware genome.We observed the expansion of gene families,especially those related to the nitrogen metabolism,and the increase of repetitive elements including transposable elements,which probably resulted in the increase of Zhongmu-4 genome compared with Medicago truncatula.Population structure analysis revealed that the accessions from Asia and South America had relatively lower genetic diversity than those from Europe,suggesting that geography may influence alfalfa genetic divergence during local adaption.Genome-wide association studies identified 101 single nucleotide polymorphisms(SNPs)associated with 27 agronomic traits.Two candidate genes were predicted to be correlated with fall dormancy and salt response.We believe that the alleleaware chromosome-level genome sequence of Zhongmu-4 combined with the resequencing data of the diverse alfalfa germplasms will facilitate genetic research and genomics-assisted breeding in variety improvement of alfalfa. | Ruicai Long Fan Zhang Zhiwu Zhang Mingna Li Lin Chen Xue Wang Wenwen Liu Tiejun Zhang Long-Xi Yu Fei He Xueqian Jiang Xijiang Yang Changfu Yang Zhen Wang Junmei Kang Qingchuan Yang | 2022 | Genomics, Proteomics & Bioinformatics2022，20，1： | 1 |
