Common buckwheat ( F. esculentum ) is an allogamy crop, which is heterogony. There is heterogeneity in the species. To reveal the genetic diversity within cultivar population, In order to explore the sampling strategy that can reveal genetic diversity of buckwheat resources on the molecular level. PCR with intron-splice junction primers and long random primers was employed to reveal the genetic diversity within nine common buckwheat varieties and one tartary buckwheat cultivar population among different individuals. We established the sampling strategy in its genetic diversity study. Then we used the established sampling strategy, and the same PCR markers technique,to analysis the genetic diversity of 86 common buckwheat resources, the main results are as follows
甜荞是花柱异长自交不亲和的异花授粉作物,品种内存在一定的异质性,为了准确揭示甜荞遗传资源的遗传多样性,本研究采用因子分析法对86份甜荞遗传资源农艺性状数据进行分析;采用长随机引物和内含子切接点引物的PCR分子标记技术,对9个甜荞品种和1个苦荞品种不同个体间的遗传多样性进行了分析,建立了甜荞资源遗传多样性研究的取样策略;并利用建立的取样策略,采用PCR标记技术,对这86份甜荞资源的遗传多样性进行了分析,取得如下主要结果

The chromosomal constitution of 200 advanced lines from 1R monosomic addition lines between the wheat cultivar Mianyang11 (MY11) and different rye lines R3, R12, and Baili-rye was studied by the improved C-banding and A-PAGE method. The result showed that 45 lines were identified as 1RS/1BL translocation lines congruously by the two methods. But a line (843-1-1), originated from an 1R addition line of wheat cultivar MY11 and rye line R12, was identified as 1RS/1BL translocation line by C-banding and genomic in situ hybridization,but the secalin block from chromosome arm 1RS of rye was absent in the A-PAGE pattern of its seed proteins.
结果发现,在鉴定的200个株系中,有45个株系经C-带和A-PAGE检测均一致地发现它们含有一对1RS /1BL易位染色体,而一个株系843-1-1,C-带鉴定、原位杂交结果均证明它含有一对1RS/1BL易位染色体,但A-PAGE醇溶蛋白图谱却不具有黑麦1RS染色体臂的黑麦碱特征带,而表达出既不同于黑麦碱又不同于亲本绵阳11的醇溶蛋白带型。

Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.
结果显示:(1)随着干旱胁迫程度的增加,2种杨树溃疡病害发生渐趋严重;(2)干旱胁迫下,杨树树皮组织细胞发生质壁分离,并随胁迫程度的增加而严重;(3)干旱胁迫下接种病原菌,2种杨树细胞发生不同程度的损伤,主要表现为细胞器发生较大变化,如出现叶绿体肿胀变形、线粒体数量增多,质膜模糊不清等现象;随接种时间的延长,细胞器受到进一步损伤,叶绿体被膜折皱,严重时局部破裂,基质外渗,并部分最终解体;(4)毛白杨中的菌丝主要在细胞间隙中穿行,而北京杨的菌丝除在细胞间隙中生长之外,侵入细胞内部也较多,直接导致细胞的解体;(5)干旱胁迫下细胞的损伤促进了病原菌的侵染,干旱和病原菌的双重胁迫加剧了病害的发生程度,并且病原菌侵染对细胞的破坏程度大于水分胁迫。
