转基因美国栗子树在新研究中显示出强烈的抗腐烂性. Transgenic American chestnut trees show strong resistance to blight in new studies.

四项独立研究证实,具有氧酸盐氧化酶基因的转基因美国栗子树对栗子病有强烈抵抗力. Four independent studies confirm that transgenic American chestnut trees with the oxalate oxidase gene show strong resistance to chestnut blight. 这些树的病变比非转基因同类小得多, 它们的表现与中国栗子相似, 这是目前抗性标准. These trees developed significantly smaller blight cankers compared to non-transgenic counterparts and performed similarly to Chinese chestnuts, the current benchmark for resistance. 研究人员发现树木生长没有负面影响, 支持大规模恢复物种的潜力. Researchers found no negative effects on tree growth, supporting the potential for large-scale restoration of the species.
