Raspberry Auxin Soil/Subtrate Protectant (RASP)

致病菌是导致爱尔兰马铃薯大饥荒的罪魁祸首，目前已有超过170种致病菌在全球范围内导致作物病害，给商业作物工业造成数十亿美元的损失。英国水果产业，尤其是覆盆子受到了植物根腐病（PRR）的严重破坏，田间产量减少了80%，导致以盆栽为基础的短期产业规模缩小[][0]，并依靠大量的水果进口。控制感染和传播的方法受到现行立法的限制，这些立法限制了预防性杀菌剂的使用，并增加了基于宿主抗性、生长介质和浇水的新型控制方法的重要性。[关键词]植物；fragariae_是通过植物繁殖、生长介质和人工林水流传播的PRRs。控制生长培养基的物理、化学和生物特性可能在抑制PRR中发挥关键作用。商业植物生长基质可以专门设计，以满足作物在养分需求、水管理和种植者偏好方面的个体需求。控制生长介质的物理、化学和生物特性可以导致更强大、更健康的根和植物系统，同时还可以限制和积极抑制有害根病原体（如PRR）的生长和传播。以前，在生长培养基中加入了特定的添加剂，以控制和预防其他根系病原体和害虫，如葡萄象鼻虫、镰孢菌和皮孢菌。最近JHI的一项研究发现，抗PRR的覆盆子植物在受到_P的攻击时引发了多种反应。包括一种机制，它有可能提高植物对PRR的抗性。通过控制这些植物源性化学信号，可以改善生长培养基，从而提高易感品种的免疫能力。这些化学信号通常是抗性品种在病原体攻击时诱导的。利用基因表达、遗传标记和荧光病原体培养等分子方法，我们可以在不同培养基基质配方的根区环境中跟踪疾病的发展。本项目开发的创新生长基质添加剂系列将刺激树莓根系生长信号，在控制灌溉制度下改善根系，其次积极抑制根系病原体的生长和传播。建立最佳覆盆子生长条件，结合早期病原体检测和PRR传播控制，将改变覆盆子农艺，最大限度地提高产量，并确保英国软果产业应用于全球其他作物。[0]: # _msocom_1

_Phytophthora infestans_ is the pathogen that caused the Great Irish Potato Famine and today over 170 described species of _Phytophthora_ cause crop disease on a global scale, costing commercial crop industries billions of dollars. The UK fruit industry and raspberry particularly has been decimated by _Phytophthora_ root rot (PRR) with an 80% reduction in field production leading to a smaller pot based short term industry[][0] supported by extensive fruit imports. Methods to control infection and spread are limited by current legislation that limit the use of prophylactic fungicides and increase the importance of novel control methods based on host resistance, growing media and watering. _Phytophthora_ _rubi_ and _P. fragariae_ are PRRs which spread through plant propagation, growth media and water flow in plantations. Manipulating the physical, chemical and biological properties of the growth medium has the potential to play a key role in inhibiting PRR. Commercial plant growth substrates can be designed specifically to meet a crops individual needs with regards to nutrient requirement, water management and grower preferences. Manipulating the growing media's physical, chemical and biological properties can lead to a stronger healthier root and plant system, while also limiting and actively suppressing the growth and spread of harmful root pathogens, such as PRR. Specific additives have previously been incorporated into growing media to control and prevent other root pathogens and pests such as Vine Weevil, _Fusarium_ spp. and _Pythium_ spp. A recent JHI study identified multiple responses triggered in a PRR resistant raspberry plant upon challenge with _P._ _rubi_, including a mechanism, which has the potential to improve a plants resistance to PRR. The growth medium can be improved by the manipulation of these plant-derived chemical signals that are normally induced upon pathogen challenge in resistant cultivars, to boost the immune capabilities of susceptible cultivars. Using molecular methods such as gene expression, genetic markers and fluorescent pathogen cultures we can track disease development in the root-zone environment in different growing media substrate formulations. The innovative range of growth substrate additives developed in this project will stimulate raspberry root growth signal to improve the root system under a controlled irrigation regime and secondly actively inhibit the growth and spread of root pathogens. Establishment of optimal raspberry growing conditions integrated with early pathogen detection and control of PRR spread will transform raspberry agronomy, maximising yield and securing the UK soft fruit industry with application to other crops worldwide.[0]: #_msocom_1
