Rust diseases cause significant reductions annually in yield of cereal crops worldwide. Traditional monoculture cropping systems apply significant selection pressure on the pathogen to cause rapid shifts in pathotypes. Plant breeders strive to stay ahead of the evolving pathogens by releasing new crop genotypes with new rust resistance genes or gene combinations. Owing to the limited number of known resistance genes and the lack of molecular understanding of the plant-pathogen interaction, rusts remain challenging organisms to study, both at organismal and molecular levels. This review discusses recent progress by a number of laboratories towards better understanding the molecular component of rust disease resistance.
锈病每年都会使全球谷类作物的产量大幅下降。传统的单一栽培种植系统对病原体施加了巨大的选择压力,导致致病型迅速转变。植物育种者努力通过发布具有新的抗锈病基因或基因组合的新作物基因型来领先于不断进化的病原体。由于已知抗性基因数量有限,以及对植物与病原体相互作用缺乏分子层面的了解,无论是在生物体水平还是分子水平,锈菌仍然是具有挑战性的研究对象。本综述讨论了一些实验室在更好地理解锈病抗性分子成分方面的最新进展。
