is the most devastating pathogen of head blight of cereals, stalk and ear of maize, and it has recently become a potential threat for soybean as maize-soybean strip relay intercropping is widely practiced in China. To elucidate the pathogenesis mechanism of on intercropped soybean which causes root rot, transcriptional profiling of at 12, 24, and 48 h post-inoculation (hpi) on soybean hypocotyl tissues was conducted. In total, 2313 differentially expressed genes (DEGs) of were annotated by both KEGG pathway and Gene Ontology (GO) analysis. Among them, 128 DEGs were commonly expressed at three inoculation time points while the maximum DEGs were induced at 24 hpi. In addition, DEGs were also rich in carbon metabolism, ribosome and peroxisome pathways which might contribute to carbon source utilization, sexual reproduction, virulence and survival of when infected on soybean. Hence, this study will provide some basis for the deep understanding the pathogenesis mechanism of on different hosts and its effective control in maize-soybean strip relay intercropping systems.
是谷物赤霉病、玉米茎和穗的最具毁灭性的病原体，并且最近随着玉米 - 大豆带状套种在中国广泛实施，它已成为大豆的潜在威胁。为了阐明其对间作大豆引起根腐病的发病机制，对接种后12、24和48小时（hpi）大豆下胚轴组织中的该病原体进行了转录谱分析。通过KEGG通路和基因本体（GO）分析总共注释了该病原体的2313个差异表达基因（DEG）。其中，128个DEG在三个接种时间点均有共同表达，而在24 hpi时诱导的DEG数量最多。此外，DEG在碳代谢、核糖体和过氧化物酶体途径中也很丰富，这可能有助于该病原体在感染大豆时的碳源利用、有性繁殖、毒力和存活。因此，本研究将为深入了解该病原体在不同寄主上的发病机制及其在玉米 - 大豆带状套种系统中的有效防治提供一些依据。
