Plants are highly adaptive and adjust their development and physiology according to the environment. Intriguingly, exposure to one type of stress seems to be able to enhance general resilience. For example, gentle physical stimulation via pressing or stroking result in boosting of structural strength (shorter and stiffer shoots), as well as tolerance against various types of biotic and abiotic stressors [1]. In fact, farmers in Japan have used such natural plant responses as a crop pre-conditioning method, which is effective enough to increase the yields of wheat and barley by 20-50% [2]. Such thigmo (touch in Greek)-priming strategy is accessible, immediately applicable, and compatible with smallholder farming, and thus has a great potential to catalyse sustainable food security in developing countries.Together with an interdisciplinary team of collaborators from social science and multiple fields of natural sciences, we are developing practical thigmo-priming protocols for cereal crops in two specific developing countries based on the environmental, social, and cultural needs and circumstances. Meanwhile, there are very little quantitative and mechanistic studies on thigmo-priming, and thus we are not able to modify protocols based on scientific data. This PhD project is to reveal input-output relationships of a variation of thigmo-priming protocols, in order to establish their biological underpinnings and to customise them for specific requirements of local farmer communities.With this project the student will be trained in molecular and systems study of plant development, as well as integrative and multi-perspective approaches for international agricultural development via collaborations with social, computer, and engineering scientists. It is likely to involve fieldworks in the UK and developing countries.

植物具有很强的适应性，可以根据环境调整其发育和生理。有趣的是，暴露在一种压力下似乎能够增强整体的恢复力。例如，通过按压或抚摸的温和物理刺激导致结构强度的提高（更短和更硬的枝条），以及对各种类型的生物和非生物应激源的耐受性[1]。事实上，日本的农民已经将这种自然植物反应作为作物预处理方法，这足以使小麦和大麦的产量增加20-50% [2]。真恶心（希腊语）-启动策略是可获得的，立即适用的，并与小农农业兼容，因此具有巨大的潜力，以促进可持续的粮食安全在发展中国家。与来自社会科学和自然科学多个领域的合作者组成的跨学科团队一起，我们正在开发实用的thigmo启动协议，用于两个特定的发展中国家的谷类作物，基于环境，社会、文化需求和环境。同时，关于thigmo启动的定量和机制研究很少，因此我们无法根据科学数据修改方案。该博士项目旨在揭示一系列触毛启动方案的输入-输出关系，以建立其生物学基础，并根据当地农民社区的具体要求进行定制。通过该项目，学生将接受植物发育的分子和系统研究，以及通过与社会，计算机，和工程科学家。它可能涉及在英国和发展中国家的实地考察。
