The function of NaPNRP in Nicotiana attenuata growth promotion stimulated by Piriformospora indica

病原微生物和食草昆虫利用植物为自己的利益（营养，繁殖）。然而，一些微生物和昆虫不仅从与植物的相互作用中受益，而且还受益于植物（例如通过刺激它们的生长或增加对环境胁迫的抗性）。为了根据相互作用的类型（防御或共生）做出反应，植物已经进化出复杂的机制来识别有益和非有益的生物体。最近的研究表明，植物用来保护自己免受攻击者和与有益微生物相互作用的机制之间存在重叠。我们以前的工作已经确定了几个基因参与的机制，植物用来识别和响应昆虫食草动物，特别是鳞翅目幼虫取食烟草植物。这些基因中的一些已被证明有助于了解昆虫特异性反应的触发机制。我们建议调查的作用，N。nepidoptera attenuata基因NaPNRP（Putative Nematode Resistant Protein），其最初被鉴定为在鳞翅目幼虫进食时强烈诱导的基因。然而，我们最近发现NaPNRP参与了N.在根有益真菌梨形孢菌（Piriformospora indica）的刺激下，在本项目中，我们拟研究NaPNRP在N. attenuata植物

Pathogenic microorganisms and herbivorous insects use plants for their own benefit (nutrition, reproduction). However some microorganisms and insects not only benefit themselves from the interaction with plants but also the plants (e.g. by stimulating their growth or increasing resistance to environmental stresses). To react according to the type of interaction (defense or symbiosis), plants have evolved sophisticated mechanisms to recognize beneficial and non-beneficial organisms. Recent studies have suggested an overlap between the mechanisms used by plants to defend themselves from attackers and to interact with beneficial microorganisms. Our previous work has identified several genes involved in the mechanisms that plants use to recognize and respond to insect herbivores, in particular to lepidopteran larvae feeding on Nicotiana attenuata plants. The characterization of some of these genes has proven instrumental to understand the mechanisms underlying the triggering of insect-specific responses. We propose to investigate the role of the N. attenuata gene NaPNRP (Putative Nematode Resistant Protein) which was originally identified as a gene strongly induced upon lepidopteran larval feeding. However, we have recently found that NaPNRP is involved in the regulation of N. attenuata growth when stimulated by the root beneficial fungus Piriformospora indica. In this project, we propose to investigate the function of NaPNRP during fungal growth stimulation of N. attenuata plants.
