| 1 | Hybrid speciation via inheritance of alternate alleles of parental isolating genes显示文摘It is increasingly realized that homoploid hybrid speciation(HHS),which involves no change in chromosome number,is an important mechanism of speciation.HHS will likely increase in frequency as ecological and geographical barriers between species are continuing to be disrupted by human activities.HHS requires the establishment of reproductive isolation between a hybrid and its parents,but the underlying genes and genetic mechanisms remain largely unknown.In this study,we reveal by integrated approaches that reproductive isolation originates in one homoploid hybrid plant species through the inheritance of altemate alleles at genes that determine parental premating isolation.The parent species of this hybrid species are reproductively isolated by differences in flowering time and survivorship on soils containing high concentrations of iron.We found that the hybrid species inherits alleles of parental isolating major genes related to flowering time from one parent and alleles of major genes related to iron tolerance from the other parent.In this way,it became reproductively isolated from one parent by the difference in flowering time and from the other by habitat adaptation(iron tolerance).These findings and further modeling results suggest that HHS may occur relatively easily via the inheritance of alternate parental premating isolating genes and barriers. | Zefu Wang Yuanzhong Jiang Hao Bi Zhiqiang Lu Yazhen Ma Xiaoyue Yang Ningning Chen Bin Tian Bingbing Liu Xingxing Mao Tao Ma Stephen P.DiFazio Quanjun Hu Richard J.Abbott Jianquan Liu | 2021 | Molecular Plant2021，14，2： | 4 |

| 4 | Pervasive hybridization during evolutionary radiation of Rhododendron subgenus Hymenanthes in mountains of southwest China显示文摘Radiations are especially important for generating species biodiversity in mountainous ecosystems.The contribution of hybridization to such radiations has rarely been examined.Here,we use extensive genomic data to test whether hybridization was involved in evolutionary radiation within Rhododendron subgenus Hymenanthes,whose members show strong geographic isolation in the mountains of southwest China.We sequenced genomes for 143 species of this subgenus and 93 species of four other subgenera,and found that Hymenanthes was monophyletic and radiated during the late Oligocene to middle Miocene.Widespread hybridization events were inferred within and between the identified clades and subclades.This suggests that hybridization occurred both early and late during diversification of subgenus Hymenan thes,although the extent to which hybridization,speciation through mixing-isolation-mixing or hybrid speciation,accelerated the diversification needs further exploration.Cycles of isolation and contact in such and other montane ecosystems may have together promoted species radiation through hybridization between diverging populations and species.Similar radiation processes may apply to other montane floras in this region and elsewhere. | Yazhen Ma Xingxing Mao Ji Wang Lei Zhang Yuanzhong Jiang Yuying Geng Tao Ma Liming Cai Shuangquan Huang Pete Hollingsworth Kangshan Mao Minghui Kang Yiling Li Wenlu Yang Haolin Wu Yang Chen Charles C.Davis Nawal Shrestha Richard H.Ree Zhenxiang Xi Quanjun Hu Richard I.Milne Jianquan Liu | 2022 | National Science Review2022，9，12： | 1 |

| 7 | Pangenome of water caltrop reveals structural variations and asymmetric subgenome divergence after allopolyploidization显示文摘Water caltrop(Trapa spp.,Lythraceae)is a traditional but currently underutilized non-cereal crop.Here,we generated chromosome-level genome assemblies for the two diploid progenitors of allotetraploid Trapa.natans(4x,AABB),i.e.,diploid T.natans(2x,AA)and Trapa incisa(2x,BB).In conjunction with four published(sub)genomes of Trapa,we used gene-based and graph-based pangenomic approaches and a pangenomic transposable element(TE)library to develop Trapa genomic resources.The pangenome displayed substantial gene-content variationwith dispensable and private gene clusters occupying a large proportion(51.95%)of the total cluster sets in the six(sub)genomes.Genotyping of presence-absence variation(PAVs)identified 40453 PAVs associated with 2570 genes specific to A-or B-lineages,of which 1428were differentially expressed,andwere enriched in organ development process,organic substancemetabolic process and response to stimulus.Comparative genome analyses showed that the allotetraploid T.natans underwent asymmetric subgenome divergence,with the B-subgenome being more dominant than the A-subgenome.Multiple factors,including PAVs,asymmetrical amplification of TEs,homeologous exchanges(HEs),and homeolog expression divergence,together affected genome evolution after polyploidization.Overall,this study sheds lights on the genome architecture and evolution of Trapa,and facilitates its functional genomic studies and breeding program. | Xinyi Zhang Yang Chen Lingyun Wang Ye Yuan Mingya Fang Lin Shi Ruisen Lu Hans Peter Comes Yazhen Ma Yuanyuan Chen Guizhou Huang Yongfeng Zhou Zhaisheng Zheng Yingxiong Qiu | 2023 | Horticulture Research2023，10，11： | 0 |
| 8 | Molecular signatures of parallel adaptive divergence causing reproductive isolation and speciation across two genera显示文摘Parallel evolution of reproductive isolation(PERI)provides strong evidence for natural selection playing a fundamental role in the origin of species.However,PERI has been rarely demonstrated for well established species drawn from different genera.In particular,parallel molecular signatures for the same genes in response to similar habitat divergence in such different lineages is lacking.Here,based on whole-genome sequencing data. | Zefu Wang Yuanzhong Jiang Xiaoyue Yang Hao Bi Jialiang Li Xingxing Mao Yazhen Ma Dafu Ru Cheng Zhang Guoqian Hao Jing Wang Richard J.Abbott Jianquan Liu | 2022 | The Innovation2022，3，3： | 0 |
| 9 | Inhibition of Flavonoids from Scutellaria baicalensis Stems and Leaves against Abnormal Formation of PHF and Regulation of PP in OA Induced Brain Injury in Rats显示文摘[Objectives] To explore the inhibitory effects of flavonoids from Scutellaria baicalensis Georgi stems and leaves against abnormal formation of PHF and regulation mechanism of protein phosphatase(PP) in okadaic acid(OA) induced brain injury in rats.[Methods]Male Sprague-Dawley rats were treated with OA(200 ng/kg) in the lateral ventricle to establish a memory impairment model,and Morris water maze was used to screen the memory impairment model.Rats were intragastrically administered with 25,50 and 100 mg/kg SSF daily for 36 d.The protein expressions of PHF,PP1,PP2A-Cα,PP2A-Cβ,PP2 CA and PP2 CB in rat cortex and hippocampus were determined by Western blot.Ginkgo biloba leaf flavonoids were used as positive control drugs.[Results]Compared with the sham-operated rats,the expression of PHF protein in the cortex and hippocampus of the model group was significantly increased(P < 0.01);protein expression of PP2A-Cα and PP2A-Cβin the cortex and hippocampus,and PP2 CB in the hippocampus were significantly decreased(P < 0.05);protein expression of PP2 CA and PP2 CB in the cortex was significantly increased(P < 0.01);protein expression of PP1 in the cortex was significantly decreased(P < 0.01).Compared with the model rats,25,50 and 100 mg/kg SSF 36 d reversed the protein expression of PHF,PP2A-Cα and PP2ACβ in rat cortex and hippocampus and expression of PP1 in rat cortex induced by OA,but had no significant effect on the protein expression of PP2 CA and PP2 CB,G.biloba flavonoids also showed similar results to SSF.[Conclusions] SSF can significantly inhibit the abnormal formation of PHF in rat brain induced by OA.The inhibitory effect may be related to the regulation of PP1,PP2A-Cα and PP2A-Cβ protein expression in cerebral cortex and hippocampus by SSF,but less related to the regulation of PP2 CA and PP2 CB. | Jianjun CHENG Hong MIAO Shuai MA Yang GAO Yazhen SHANG | 2018 | Medicinal Plant2018，9，6： | 0 |
| 10 | A chromosome-scale reference genome of Lobularia maritima,an ornamental plant with high stress tolerance显示文摘Lobularia maritima(L.)Desv.is an ornamental plant cultivated across the world.It belongs to the family Brassicaceae and can tolerate dry,poor and contaminated habitats.Here,we present a chromosome-scale,high-quality genome assembly of L.maritima based on integrated approaches combining Illumina short reads and Hi–C chromosome conformation data.The genome was assembled into 12 pseudochromosomes with a 197.70 Mb length,and it includes 25,813 protein-coding genes.Approximately 41.94%of the genome consists of repetitive sequences,with abundant long terminal repeat transposable elements.Comparative genomic analysis confirmed that L.maritima underwent a species-specific whole-genome duplication(WGD)event~22.99 million years ago.We identified~1900 species-specific genes,25 expanded gene families,and 50 positively selected genes in L.maritima.Functional annotations of these genes indicated that they are mainly related to stress tolerance.These results provide new insights into the stress tolerance of L.maritima,and this genomic resource will be valuable for further genetic improvement of this important ornamental plant. | Li Huang Yazhen Ma Jiebei Jiang Ting Li Wenjie Yang Lei Zhang Lei Wu Landi Feng Zhenxiang Xi Xiaoting Xu Jianquan Liu Quanjun Hu | 2020 | Horticulture Research2020，7，1： | 0 |
