    摘要:

    玉米是世界上最重要的作物之一,在中国,玉米总产量占全国粮食总产量的41.5%。茎腐病严重危害玉米安全生产,降低玉米的产量和品质,增加机械化收获的难度,其致病菌甚至会产生毒素污染粗饲料,威胁牲畜安全。目前,国内外对茎腐病的致病菌进行了较多的研究,分离出了30余种真菌致病菌,其中镰孢菌和腐霉菌是我国最主要的致病菌类型。土埋法、伤根法、注射法和牙签法是进行玉米抗茎腐病鉴定较为常用的接种方法,从数千份玉米资源中鉴定出了一批具有优异抗性的种质。针对部分抗病材料进行了抗性遗传分析和基因定位研究,鉴定出了46个茎腐病抗性的位点,并利用多组学对抗性机制进行了初步探析。克隆出了ZmCCT和ZmAuxRP1两个与茎腐病抗性相关的基因并进行了抗性机制解析。尽管如此,抗性研究用于生产实践的实例仍很少,生产上缺乏高产优质的抗茎腐病玉米品种。本文从玉米茎腐病致病菌的复杂性及主要致病菌的地域分布特征、茎腐病毒素、抗茎腐病种质资源的鉴定与筛选、玉米对茎腐病的抗性遗传、抗性基因挖掘、克隆与抗性机制解析等相关研究进行了总结,提出了一些当前面临的问题和对未来研究的展望,以期对玉米抗茎腐病研究提供参考。

    Abstract:

    Maize is one of the most important crops in the world. The maize yield accounts for 41.5% of gross grain yields in China. Stalk rot seriously harms maize production, reducing the yield and quality and increasing the difficulty in mechanized corn harvesting. Furthermore, the pathogens causing stalk rot produces mycotoxins that contaminate roughage forage and hazard the safety of livestock. Up to date, more than 30 kinds of fungi causing maize stalk rot have been isolated and identified, among which Fusarium spp. and Pythium spp. are the main pathogenic fungi in China. Soil inoculation, root injury method, drilling inoculation and toothpick method are the commonly used methods to identify maize resistance to stalk rot. Some maize germplasm with excellent stalk rot resistance have been identified from thousands of resources. Resistance genetic analysis and gene mining were carried out in some materials, and 46 loci with stalk rot resistance were mapped, and then resistance mechanism was analyzed by multi-omics analysis. Two genes, ZmCCT and ZmAuxRP1, were cloned and the resistance mechanism was explored. Even so, there are still few cases of resistant maize varieties with high yield and quality cultivated widely in production practice. In this paper, the advances in maize stalk rot resistance were summarized from the aspects, including diverse pathogens and regional distribution, mycotoxins, identification and screening of resistant maize germplasm resources, resistance genetics, resistance gene mining and cloning, and mechanism exploring. Some current problems and future prospects were put forward. The main aim is to provide reference for the research on maize resistance to stalk rot.
