Deciphering defense mechanisms primed by a rhamnolipid in wheat towards Zymoseptoria tritici

We revealed that a rhamnolipid protects wheat against the hemibiotrophic fungal pathogen Zymoseptoria tritici. Foliar application of the biomolecule primes, during the early stages of infection, the expression of genes associated with different functional groups of genes. Wheat plants treated with rhamnolipid (R) or not (control, C), and inoculated with Z. tritici (i) or not (Ni) were analyzed for their gene expression.

本研究揭示，鼠李糖脂（rhamnolipid）可保护小麦免受半活体营养型真菌病原菌小麦壳针孢（Zymoseptoria tritici）的侵染。在病原菌侵染早期阶段，经叶面施用该鼠李糖脂，可诱导不同功能类别的基因表达。研究人员对四组小麦植株的基因表达情况进行了分析：分别经鼠李糖脂处理（记为R组）与未处理的对照组（记为C组），以及接种（记为i组）与未接种（记为Ni组）Z. tritici的植株。
