背景：

Peroxidase:? [p?'rɑks?,des; p?'rɑks?,dez]? n. [生化]過氧物酶

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

結(jié)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.

日積月累：

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

Favorable：['fe?v?r?bl]? ? adj.有利的；良好的；贊成的，贊許的；討人喜歡的

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 ：[?p?r?m?d]? ? n.金字塔；角錐體 vi. 漸增；上漲；成金字塔狀

vt. 使…漸增；使…上漲；使…成金字塔狀

chlorosis: [kl?'ros?s]? n.變色病；[植保]萎黃病

inferior: [?n?f?ri?r] adj.差的；自卑的；下級的，下等的 n. 下級；次品

inferior grain quality

render: ['rend?]? vt.致使；提出；實施；著色；以…回報vi. 給予補償n. 打底；交納；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.
