Chenopodium quinoa (quinoa) is a highly nutritious crop native to the Andes with remarkable capacity for growing in marginal climates across 70 different countries. Quinoa has adapted for growth on nutrient-poor or highly saline soils across an altitudinal gradient of 4000m and withstands temperature fluctuations of over 40 degrees. The quinoa germplasm has over 6000 accessions and represents an invaluable genetic resource for investigating the underlying mechanisms of its hardiness. Climatic changes and expansion of crop species to new areas brings new pathogen threats and there is an ever-greater need for investigating how plants perceive and respond to biotic and abiotic stresses applied in combination. Using quinoa, the model pathogen Pseudomonas syringae and salt stress the relationships between biotic and abiotic stress defence pathways will be unravelled. Genetic, physiological and biochemical techniques will characterise quinoa's stress responses at multiple levels: morphologically, and via cellular and molecular components. To strengthen the depth of characterisation and widen the applicability of this research several agroecologically distinct quinoa varieties native to Bolivia will be tested. The biotic stress tolerance of quinoa, namely quinoa's immunity has never been fully characterised before and this project aims to establish a toolbox for interrogating plant-pathogen interactions in quinoa. This will be increasingly relevant considering the demand for expansion of nutritious crop species to new areas and for the optimisation of productivity on sub-optimal land in a changing climate.BBSRC priority areas:Sustainably enhancing agricultural productionFood, nutrition and health

藜麦（藜麦）是原产于安第斯山脉的一种营养丰富的作物，在70个不同国家的边缘气候中具有非凡的生长能力。藜麦已经适应了在4000米海拔梯度的营养贫乏或高盐土壤上生长，并能承受40度以上的温度波动。藜麦种质资源有超过6000加入，并代表了一个宝贵的遗传资源，调查其抗寒性的基本机制。气候变化和作物品种向新地区的扩展带来了新的病原体威胁，并且越来越需要研究植物如何感知和响应生物和非生物胁迫的组合。使用藜麦，模式病原体假单胞菌和盐胁迫的生物和非生物胁迫防御途径之间的关系将被解开。遗传学、生理学和生物化学技术将在多个水平上研究藜麦的应激反应：形态学上，以及通过细胞和分子成分。为了加强表征的深度和扩大本研究的适用性，将对原产于玻利维亚的几种农业生态上不同的藜麦品种进行测试。藜麦的生物胁迫耐受性，即藜麦的免疫力，以前从未被充分表征过，该项目旨在建立一个用于询问藜麦中植物-病原体相互作用的工具箱。考虑到将营养作物品种扩大到新的地区以及在气候变化的情况下优化次优土地的生产力的需求，这一点将越来越重要。
