Abstract

Evidence indicating that barley-stripe-mosaic virus has a mutagenic effect on maize is presented. The frequency of deficiencies of marker genes in F(1) seeds was significantly greater from pollinations involving viruis-infected males than from healthy controls. A small percentage of F(2) ears, involving virus-infected P(1) males, exhibited marked ratio distortions for marker genes. Such distortions persisted in subsequent back-cross generations.

摘要

本文提供了表明大麦条纹花叶病毒对玉米具有诱变作用的证据。与健康对照相比，涉及感染病毒的雄性植株授粉所产生的F(1)种子中标记基因缺失的频率显著更高。一小部分涉及感染病毒的P(1)雄性植株的F(2)穗，其标记基因表现出明显的比例畸变。这种畸变在随后的回交世代中持续存在。
