摘要:

由禾谷镰刀菌引起的小麦赤霉病直接为害作物穗部,不仅严重影响小麦产量,还可因为毒素污染问题威胁人畜健康。近年来对小麦与禾谷镰刀菌互作的转录组学研究带来了很多新见解,概述了小麦响应禾谷镰刀菌侵染的转录组学研究进展,主要比较了不同抗性品种、不同器官、不同籽粒发育时期的小麦穗部在禾谷镰刀菌侵染时的基因表达特征,总结了赤霉病感染时小麦的激素响应、信号传导、转录调控和防卫相关基因的表达规律,以期促进研究者对小麦响应禾谷镰刀菌侵染规律的理解。

Abstract:

Fusarium head blight (FHB), which is major caused by Fusarium graminearum, damages wheat spikes directly. It not only affects the yield of wheat, but also threatens the health of humans and livestock due to contamination of mycotoxin. In recent years, many progresses have been achieved in transcriptomics research on the interaction between wheat and F. graminearum. This review focused on the response of wheat genes upon F. graminearum infection. We mainly compared the gene expression of wheat ears on different varieties, different organs, and different developmental stages during infection. We also summarized the genes differentially expressed in phytohormonal response, signal transduction, transcriptional regulation, and plant defense. The review was expected to facilitate our understanding of how wheat response to F. graminearum infection.

Key words: Fusarium head blight, wheat, Fusarium graminearum, transcriptome
