Wild rice MAGIC

自绿色革命以来，栽培水稻有限的遗传变异是导致产量提高速度下降的主要因素。在水稻的野生近缘种中存在大量未被充分利用的遗传变异，这些变异可以提高对逆境的耐受性。我们将启动第一个项目，从所有野生水稻中混合等位基因，选择在胁迫下有益的等位基因引入栽培水稻。迄今为止，来自个别非驯化水稻品种的等位基因已被组合成优良品种。虽然有用，但范围有限，并且忽略了野生亲缘关系中存在的许多未表征的等位基因变异。此外，结合基因组可以在后代中产生父母所没有的理想表型。这个育种计划将通过对我们产生的品种的基因组分析和表型分析来评估每个品种对各种压力的反应。我们生产的种质将提供给非洲和印度的合作伙伴进行田间试验，并使优质种子能够迅速供应给农民。

Limited genetic variation in cultivated rice is a major factor responsible for the declining rates of yield improvement since the Green Revolution. Substantial and underexploited genetic variation exists within wild relatives of rice that improve tolerance to stresses. We will initiate the first program to mix alleles from all wild-rices, select those with benefit under stress and introduce them into cultivated rice. To date, alleles from individual non-domesticated rice species have been combined into elite varieties. While useful, this is both limited in scope and ignores much of the uncharacterized allelic variation present in wild-relatives. Furthermore, combining genomes can produce desirable phenotypes in progeny that are absent in parents. This breeding program will be underpinned by analysis of the genomes of the lines that we generate and by phenotyping to assess how each line responds to a wide range of stresses. The germplasm that we generate will be supplied to partners in Africa and India for testing in field sites, and to allow speedy supply of good seed to farmers.
