    背景:

    Peroxidase:  [pə'rɑksɪ,des; pə'rɑksɪ,dez]  n. [生化]过氧物酶

    Digu is a rice variety carryingdurable, high-level resistance to a broad-spectrum of M. oryzae races

    Bsr-d1 encodes a C2H2-typetranscription factor, which is directly regulated by a MYB family transcriptionfactor.

    LTH:highly susceptible rice variety

    结果:

    A single nucleotide change in the promoter of the bsr-d1 gene,which results in reduced expression of the gene through the binding of the repressive MYB transcription factor and, consequently, an inhibition of H2O2 degradation(through the suppression of two Peroxidase Genes) and enhanced disease resistance.

    日积月累:

    The PTI response includesactivation of MAP kinases, induction of reactive oxygen species (ROS),deposition of callose, and induction of pathogenesis-related (PR) genes

    Favorable:['feɪvərəbl]    adj.有利的;良好的;赞成的,赞许的;讨人喜欢的

    favorable trait

    1.Non-race-specific resistance hasbeen more effective in controlling crop diseases than race-specific resistancebecause of its broad spectrum and durability.

    2.Because pyramiding R genes to combatdiseases is an extremely time-consuming process, deployment of genes conferringbroad-spectrum, durable resistance is highly favored by breeders.

    Pyramid :[ˈpɪrəmɪd]    n.金字塔;角锥体 vi. 渐增;上涨;成金字塔状

    vt. 使…渐增;使…上涨;使…成金字塔状

    chlorosis: [klə'rosɪs]  n.变色病;[植保]萎黄病

    inferior: [ɪnˈfɪriər] adj.差的;自卑的;下级的,下等的 n. 下级;次品

    inferior grain quality

    render: ['rendə]  vt.致使;提出;实施;着色;以…回报vi. 给予补偿n. 打底;交纳;粉刷

    3.Digu is a rice variety carryingdurable, high-level resistance to a broad-spectrum of M. oryzae races (Chen etal., 2006; Li et al., 2016),rendering it an excellent resource fordiscovery of novel genes conferring broad-spectrum resistance.

    Morphologically: adv. 词法地;形态学上地

    Conidia: [kə'nɪdiə]  n.分生孢子(conidium的复数)

    Scattered:[ˈskætəd]  adj.分散的;散乱的  scattered lesions

    Notorious:[noʊˈtɔːriəs]  adj.声名狼藉的,臭名昭著的  notorious rice blast pathogen.
