| 1 | Reprogramming of a defense signaling pathway in rough lemon and sweet orange is a critical element of the early response to‘Candidatus Liberibacter asiaticus’显示文摘Huanglongbing(HLB)in citrus infected by Candidatus Liberibacter asiaticus(CLas)has caused tremendous losses to the citrus industry.No resistant genotypes have been identified in citrus species or close relatives.Among citrus varieties,rough lemon(Citrus jambhiri)has been considered tolerant due to its ability to produce a healthy flush of new growth after infection.The difference between tolerance and susceptibility is often defined by the speed and intensity of a plant’s response to a pathogen,especially early defense responses.RNA-seq data were collected from three biological replicates of CLas-and mock-inoculated rough lemon and sweet orange at week 0 and 7 following infection.Functional analysis of the differentially expressed genes(DEGs)indicated that genes involved in the mitogen activated protein kinase(MAPK)signaling pathway were highly upregulated in rough lemon.MAPK induces the transcription of WRKY and other transcription factors which potentially turn on multiple defense-related genes.A Subnetwork Enrichment Analysis further revealed different patterns of regulation of several functional categories,suggesting DEGs with different functions were subjected to reprogramming.In general,the amplitude of the expression of defense-related genes is much greater in rough lemon than in sweet orange.A quantitative disease resistance response may contribute to the durable tolerance level to HLB observed in rough lemon. | Qibin Yu Chunxian Chen Dongliang Du Ming Huang Jiqiang Yao Fahong Yu Ronald H Brlansky Frederick G.Gmitter Jr | 2017 | Horticulture Research2017,4,1: | 5 |
| 2 | 柑桔线虫抗性主基因座Tyr1的特异标记开发与遗传作图改进(英文)显示文摘本文利用先期从BAC文库获得的NBS-LRR类候选抗病基因克隆序列Pt8a和Pt9a,进一步开发与柑桔线虫抗性主效基因位点Tyr1连锁的分子标记。以Pt8a和Pt9a序列作探针,通过高密度克隆印迹杂交,从BAC文库筛选出200个以上的阳性克隆,以阳性克隆插入序列设计引物,对柑桔抗线虫材料和感线虫材料开展以PCR扩增为基础的集群分离分析,发现一部分克隆序列与柑桔线虫抗性主效基因位点Tyr1紧密连锁;再通过染色体步行测序,分别从3个克隆(7A4,4L17和29F20)获得3个完整的NBS-LRR类候选抗病基因序列。从此类序列开发更高特异性的分子标记,并在利用原有分子标记的基础上,对柑桔线虫抗性杂交后代群体(9145family)构建较高密度的遗传图谱;同时,将新开发的分子标记应用于柑桔衰退病抗性杂交后代群体(9401family),以初步估算柑桔线虫抗性主效基因位点Tyr1与柑桔衰退病抗性基因Ctv的遗传距离。本文利用先期从BAC文库获得的NBS-LRR类候选抗病基因克隆序列Pt8a和Pt9a,进一步开发与柑桔线虫抗性主效基因位点Tyr1连锁的分子标记。以Pt8a和Pt9a序列作探针,通过高密度克隆印迹杂交,从BAC文库筛选出200个以上的阳性克隆,以阳性克隆插入序列设计引物,对柑桔抗线虫材料和感线虫材料开展以PCR扩增为基础的集群分离分析,发现一部分克隆序列与柑桔线虫抗性主效基因位点Tyr1紧密连锁;再通过染色体步行测序,分别从3个克隆(7A4,4L17和29F20)获得3个完整的NBS-LRR类候选抗病基因序列。从此类序列开发更高特异性的分子标记,并在利用原有分子标记的基础上,对柑桔线虫抗性杂交后代群体(9145family)构建较高密度的遗传图谱;同时,将新开发的分子标记应用于柑桔衰退病抗性杂交后代群体(9401family),以初步估算柑桔线虫抗性主效基因位点Tyr1与柑桔衰退病抗性基因Ctv的遗传距离。 | 向旭 邓占鳌 郑启发 陈存贤 Frederick G.Gmitter Jr | 2009 | 分子植物育种2009,7,3: | 2 |
