    • 摘要: 小麦(Triticum aestivum L.)是我国的主要的粮食作物之一,高产、稳产对我国粮食安全至关重要。白粉病菌(Blumeria graminis f. sp. tritici, Bgt)是威胁小麦生产的籽粒病害,其具有发生范围广、传播快、危害大等特点,可对我国的小麦生产、食品安全产生威胁。本文综述了小麦白粉病危害、抗性基因、抗病育种等方面的研究进展,旨在为小麦抗白粉病研究提供参考。

    • 摘要: 来自西班牙农业基因组学研究中心(CRAG)和农业食品研究与技术所(IRTA)的研究人员在桃树中发现了抗白粉病基因。白粉病为真菌性病害,病原菌为白粉病菌(Podosphaera pannosa)。由于防治白粉病需要使用杀菌剂,既给生产者造成经济损失,也对环境造成显著影响。该研究还提供了新的分子工具来开发和鉴定具有抗白粉病基因的桃树品种,从而减少在生产过程中喷洒杀虫剂。

    • 摘要: 规模化定位小麦品种携带的抗白粉病基因对于抗病性种质创新和新品种选育具有重要的意义.本研究采用Illumina Infinium iSelect 90k SNP芯片结合集群分离分析法(bulked segregate analysis,BSA)对36个河南省小麦新品系携带的抗白粉病基因进行了定位.SNP芯片检测表明,在24个小麦品系构建的抗、感池DNA间可检测到一个明显富集的SNP峰,表明其可能携带单一主效抗白粉病基因;在其他12个小麦品系构建的抗、感池DNA间可检测到多个SNP峰,推测其可能含多个抗白粉病基因.有26个小麦品系在2AL染色体上检测到的SNP数目最多,推测其携带位于2AL染色体上的Pm4b抗白粉病基因.开发出与2AL染色体上抗白粉病基因紧密连锁的分子标记Xwggc116,可用于这些小麦品系中抗白粉病基因的分子检测.研究结果表明,高通量SNP分析技术平台可以用来规模化定位小麦品种中的抗白粉病基因.明确了河南省抗白粉病小麦品系中携带Pm2、Pm4b、Pm21和新1BL/1RS易位等有限的抗白粉病基因,抗病基因资源非常狭窄,亟需引进新的多样化抗病基因资源,拓宽遗传基础,培育抗病小麦新品种.%Large-scale detection of powdery mildew resistance genes is necessary for wheat germplasm innovation and breeding, especially via marker assisted selection. Illumina 90k iSelect SNP chip and Bulked Segregate Analysis (BSA) were applied to identify powdery mildew resistance gene in 36 wheat varieties (lines) from Henan province. SNP genotyping between 36 resistant bulks and 36 susceptible bulks revealed that single polymorphic SNP peaks were identified between 24 of the 36 bulk pairs, indi-cating single powdery mildew resistance gene may present in the 24 varieties (lines). Multiple polymorphic SNP peaks were found between other 12 resistant and susceptible bulks, indicating more than one powdery mildew resistance gene might be in these varieties (lines). Among the 36 bulk pairs, 26 showed the largest number of SNP enriched on chromosome 2AL, indicating the powdery mildew resistance genes, most likely on Pm4 locus, were in these 26 varieties (lines). A new marker Xwggc116 was developed and proved to be effective for detecting the powdery mildew resistance gene on 2AL. Overall, the combination of BSA and high-throughput SNP genotyping platform is highly effective for large scale powdery mildew resistance gene detection in wheat germplasm. There are a limited number of powdery mildew resistance genes (Pm2, Pm4, Pm21, and new 1BL/1RS trans-location) in wheat varieties (lines) of Henan province, indicating very narrow genetic diversity of the powdery mildew resistance genes in wheat breeding program. Exploring and utilization of new diversified disease resistance genes are urgent for breedingnew varieties with disease resistance.

    • 摘要: Pm48 is a novel powdery mildew resistance gene identified previously in our laboratory. This study aimed at develop-ing close molecular markers for fine mapping of the gene. The ddRAD-sequencing assay revealed 81 SNPs associated with the target gene, in which one converted into the STS markerXmp931 and three converted into the CAPS markersXmp928,Xmp930, andXmp936. We also developed 71 genomic SSR markers according to the genome sequence ofAegilops tauschii. And mapped two of them,Xmp1089 and Xmp1112. Using the 115 F2:3 families derived from the cross of Ningnuomai 1´ Tabasco, the target gene was found to be co-segregated withXmp928 and distal toXmp1112 with the genetic distance of 3.1 cM towards centromere. In the 671 homozygous susceptible families,Xmp928 also showed co-segregated with the target gene. We also physically mapped Pm48 to the bin of 5DS 0.63–0.67 by using three Chinese Spring 5DS deletion lines.%Pm48为本实验室鉴定的一个抗白粉病新基因。为精细定位该基因,利用混池ddRAD测序鉴定了81个与该基因关联的序列,开发了STS标记Xmp931,转化了CAPS标记Xmp928、Xmp930和Xmp936;同时,利用粗山羊草基因组序列开发了71个基因组SSR标记,定位了其中的Xmp1089和Xmp1112。在115个宁糯麦1号´Tabasco衍生的 F2:3家系中,Xmp928与目的基因共分离,Xmp1112位于近着丝粒方向处距抗病基因3.1 cM。在671个纯合感病家系中,标记Xmp928仍与目的基因共分离。利用3个中国春5DS缺失系,最终将Pm48定位在小麦5DS上0.63–0.67的臂区段中。

    • 摘要: To identify the genetic characteristic of powdery mildew resistance gene in wheat genotype Shannong 10103,F2 segregation population derived from the cross between Shannong 10103 and Huixianhong was created and molecular marker analysis was carried out in this study.The results showed that Shannong 10103 and Shannong 10103 Huixianhong F1 were resistant to powdery mildew in seedlings,and the segregation ratio of resistant and sus-ceptible plants in F2 was 3∶1.All these results suggested that the powdery mildew resistance in Shannong 10103 was controlled by a dominant gene,named PML10103.Through screening 2 606 pairs of SSR,EST-SSR and STS primers for polymorphism in the parents and preferred group, seven SSR, EST-SSR markers ( Xcinau188, XCAU127, CFE164,CWM109,SWES231,Xcnl113 and SWES1015) were linked to PML10103.The genetic distance between the powdery mildew resistance gene and the SSR,EST-SSR markers-Xcinau188,XCAU127,CFE164,CWM109, SWES231,Xcnl113 and SWES1015 were 0.4,0.7,4.8,3.0,4.9,3.3,0.9 cM,respectively.Take the advantage of the known molecular linkage map,PML10103 was mapped on wheat chromosome 6B.%为明确小麦种质系山农10103抗白粉病基因的遗传特点,利用山农10103与高度感染白粉病的小麦品种辉县红杂交构建 F2分离群体,并利用分子标记技术对抗白粉病基因进行了染色体定位。结果表明,辉县红高度感染白粉病,山农10103和山农10103×辉县红 F1对白粉病表现为免疫或近免疫,F2群体抗感分离符合3∶1的分离比例,证明山农10103的白粉病抗性由1对显性主效基因控制,暂将其命名为 PML10103;在2606对 SSR、ETS-SSR 和 STS 引物中,筛选得到7个与白粉病基因 PML10103连锁的标记 Xcinau188、XCAU127、CFE164、CWM109、SWES231、Xcnl113和 SWES1015,它们与抗白粉病基因的连锁距离分别为0.4,0.7,4.8,3.0,4.9,3.3,0.9 cM;根据已发表的分子标记图谱,将 PML10103定位在6B 染色体上。
