植物先天免疫系統

植物在生長過程中會和許多微生物有接觸,其中有許多微生物能夠感染植物並造成病害。有一些植物病原性的微生物能夠感染重要的經濟作物,造成農業上重大的損失。為了抵抗植物病原菌的侵染,植物利用其免疫系統來偵測病原菌並限制病原菌的生長。其中包含利用細胞表面的PRR免疫受體及細胞內部的NLR 免疫受體來辨識來自病原菌的分子並引發免疫訊息傳導。許多的免疫受體具有抗病蛋白的功能,能夠保護植物避免病原菌的感染,因此非常具有在農業上應用的價值。

PRR位於細胞膜上,偵測胞外來自病原菌的PAMP,而NLR位於細胞內部,偵測由病原菌分泌到細胞內部的效應蛋白。在偵測到來自病原菌的分子之後,這些免疫受體活化下游防禦訊息傳遞,達成由PRR介導的免疫反應或由NLR介導的免疫反應。有些NLR可以單獨作用,不需依賴其他NLR來辨識病原菌及引發防禦反應。有些NLR則需共同作用,這些共同作用的NLR可以進一步地被分為可以辨識病原菌的“偵測型NLR”及引發下游免疫訊號的“輔助型 NLR”。


茄科植物的NRC免疫受體網絡

近期的研究發現NLR可以單獨作用、成對作用或是形成複雜的網絡。茄科植物的NRC網絡由多個能夠辨識不同病原菌的偵測型NLR及三個主要的輔助型 NLR (NRC2, NRC3, 及NRC4)所組成。這三個NRC在功能上有部分的重疊性但又對不同的偵測型NLR具有專一性。除此之外,NRC家族和依賴NRC的偵測型NLR在演化樹上屬於同一個大演化支內的不同次分支群。這些研究不僅顯示NLR免疫受體可以形成複雜的網絡來達成對於多種不同病原體的抗病性,更將NLR免疫受體的演化進程和涉及的免疫訊息傳遞進行連結。

本實驗室的研究著重於了解植物免疫系統的演化及功能,我們希望能夠回答關於NRC網絡的以下三個問題:

  1. 輔助型 NLR與偵測型NLR如何協同作用?
  2. NRC網絡如何在不同植物組織有專一化的現象?
  3. NRC網絡在不同的植物演化支系內有什麼不同的演化進程?
