B-A translocations have been used to map the catalase genes, Cat1, Cat2, and Cat3 of Zea mays. Cat1 was found to be on the short arm of chromosome 5, 9.1 map units from brittle endosperm (bt 1). Cat2 was located on chromosome 1S, while Cat3 was located on the distal half of chromosome 1L. There was no linkage between Cat2 and Cat3. The significance of mapping the catalase structural genes is discussed.
B-A 易位被用于定位玉米的过氧化氢酶基因 Cat1、Cat2 和 Cat3。Cat1 位于第 5 号染色体短臂上，距离脆性胚乳（bt1）9.1 图谱单位。Cat2 位于 1S 染色体上，而 Cat3 位于 1L 染色体的远半部分。Cat2 和 Cat3 之间没有连锁。讨论了定位过氧化氢酶结构基因的意义。
