Genetic analyses of the rp1 rust resistance complex of maize have demonstrated that recombination plays a central role in the creation of genetic diversity at the locus. The generation of rp1 diversity is promoted by a high rate of intragenic recombination coupled with a tendency for genes in the complex to mispair in meiosis. Among the novel rp1 genes that have been identified include genes with novel race-specificities and genes conferring lesion mimic phenotypes. Recombinants have also been identified that confer partial resistance which is apparently non-race-specific and may be useful in controlling maize rusts in a durable manner.

赋予玉米抗锈性的rp1复合物的结构和演化。

玉米的rp1耐锈性复合体的遗传分析表明，重组在基因座遗传多样性的产生中起着核心作用。rp1多样性的产生是由高速率的基因内重组以及减数分裂中复合物中基因错配的趋势促进的。在已经确定的新型rp1基因中，包括具有新型种族特异性的基因和赋予病灶模拟表型的基因。还已经鉴定出赋予部分抗性的重组，这些抗性显然是非种族特异性的，并且可用于以持久的方式控制玉米锈病。
