| 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 |
| 2 | Carbon Dynamics in Woody Biomass of Forest Ecosystem in China with Forest Management Practices under Future Climate Change and Rising CO_2 Concentration显示文摘It is critical to study how different forest management practices affect forest carbon sequestration under global climate change regime.Previous researches focused on the stand-level forest carbon sequestration with rare investigation of forest carbon stocks influenced by forest management practices and climate change at regional scale.In this study,a general integrative approach was used to simulate spatial and temporal variations of woody biomass and harvested biomass of forest in China during the 21st century under different scenarios of climate and CO2 concentration changes and management tasks by coupling Integrated Terrestrial Ecosystem Carbon budget(InTEC) model with Global Forest Model(G4M).The results showed that forest management practices have more predominant effects on forest stem stocking biomass than climate and CO2 concentration change.Meanwhile,the concurrent future changes in climate and CO2 concentration will enhance the amounts of stem stocking biomass in forests of China by 12%–23% during 2001–2100 relative to that with climate change only.The task for maximizing stem stocking biomass will dramatically enhance the stem stocking biomass from 2001–2100,while the task for maximum average increment will result in an increment of stem stocking biomass before 2050 then decline.The difference of woody biomass responding to forest management tasks was owing to the current age structure of forests in China.Meanwhile,the sensitivity of long-term woody biomass to management practices for different forest types(coniferous forest,mixed forest and deciduous forest) under changing climate and CO2 concentration was also analyzed.In addition,longer rotation length under future climate change and rising CO2 concentration scenario will dramatically increase the woody biomass of China during 2001–2100.Therefore,our estimation indicated that taking the role of forest management in the carbon cycle into the consideration at regional or national level is very important to project the forest carbon sequestration under future climate change and rising atmospheric CO2 concentration. | ZHOU Lei WANG Shaoqiang Georg KINDERMANN YU Guirui HUANG Mei Robert MICKLER Florian KRAXNER SHI Hao GONG Yazhen | 2013 | Chinese Geographical Science2013，23，5： | 3 |

| 5 | 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 |
| 6 | An integrative analysis of metabolomics,DNA methylation and RNASeq data reveals key genes involved in albino tea'Haishun 2'显示文摘Albino tea,a type of tea closely associated with the chlorophyll-deficient phenotype is of great interest due to its multiple benefits to human health.To explore the potential mechanisms involved in albino tea,we performed metabolomics,DNA methylation and RNA-Seq analysis of green and albino leaves in a special tea mutant'Haishun 2'.The albino leaves accumulated significantly less catechins compared with the green leaves,which is closely associated with their difference in chlorophyll formation.A total of 385 candidate genes were identified by the integrative analysis.Two NAC transcription factors were less methylated and highly up regulated in the albino leaves of'Haishun 2',which was the first identification of the key roles of NAC transcription factors in albino tea and worth further study.Many genes involved in catechin biosynthesis were down regulated in albino leaves,such as 4-coumarate-CoA ligase,flavonol synthase and leucoanthocyanidin reductase genes,suggesting chlorophyll formation is important for catechin biosynthesis.Furthermore,CsMYB5 and CsGSTF11 were found to be differentially methylated and expressed in albino and green leaves,indicating their potential roles in catechin accumulation.This was the first report of the integrative analysis of transcriptome and DNA methylation data in tea plants and the results suggest that the integrative analysis is useful for exploring key genes associated with epigenetic changes in tea plants. | Kang Wei Shuping Yu Qili Quan Shirin Aktar Mengdi He Yazhen Zhang Huihan Fang Rongmei Wu Li Ruan Peng Mao Peixian Bai Liyun Wu Hao Cheng Liyuan Wang | 2022 | Beverage Plant Research2022，2，1： | 0 |
