Treatment of Pisum sativum (L.) cv ;Sparkle' with ethylmethane sulfonic acid produced a stable mutant, E107, which forms few nodules. The mutant allele exhibits other pleiotropic properties including bronze necrotic spots on the leaflets and high accumulation of iron in the shoot. The mutant phenotype is under monogenic recessive control. The gene, designated brz (bronze), is nonallelic with two other genes conditioning necrotic spots on leaves of other mutants of P. sativum. The brz allele was located on chromosome 4 by linkage with wax production controlled by alleles at the was locus.
豌豆用乙烷磺酸处理产生了一个稳定的突变体 E107,该突变体形成的根瘤很少。突变等位基因表现出其他的表型多效性,包括小叶上的青铜坏死斑和地上部铁的高积累。突变表型受单基因隐性控制。该基因命名为 brz(青铜),与控制其他豌豆突变体叶片坏死斑的另外两个基因不同位。brz 等位基因位于第 4 染色体上,与由 was 基因座等位基因控制的蜡质产生连锁。
