Perennial wall rocket (Diplotaxis tenuifolia; Brassicaceae) is becoming an increasingly important food crop for its high nutrient content, ease of use in ready-made salads, and environmentally friendly perennial life history strategy. While most crops use C3 photosynthesis, rocket uses a rare and poorly understood type of physiology called C2 photosynthesis. Plants that use C2 photosynthesis are efficient under warm, dry, and bright environments- but are also fairly plastic and should be able to shift physiologies between C3 and C2 pathways to maintain efficiency under different growth conditions. This CTP is therefore designed to characterize the photosynthetic diversity across rocket varieties (e.g., do those varieties originating from cold northern latitudes show weaker C2 characteristics than varieties originating from warm southern Europe?) and determine the degree to which each rocket variety can shift between C2 vs C3 photosynthetic pathways under different environments. Studentship aims: 1. curate a collection of diverse rocket varieties; 2. grow this diversity under different growth conditions in a set of field trials (i.e., in southern Italy, northern Italy, Spain, and the UK) and under controlled environment conditions as part of a placement with Bakkavor; 3. quantify the biomass and flavour profile of diverse rocket varieties under each set of growth conditions; and4. determine to what degree the physiology varies or remains constant across these rocket varieties in different environments, and how this affects yield and flavour. Shifts between C2 and C3 physiology will be assessed in rocket leaves via quantification of physiological, anatomical, and 13C stable isotope parameters. This PhD project will ultimately identify the rocket varieties and environmental conditions that convey yield and flavour consistency and maximise biomass and flavour, to improve the sustainability and consumer attractiveness of this important crop.

多年生的壁火箭（Tenuifolia; brassicaceae）正在成为越来越重要的粮食作物，它的养分含量很高，在现成的沙拉中易于使用以及环保的多年生生活历史策略。尽管大多数作物都使用C3光合作用，但火箭使用了一种罕见且知之甚少的生理学类型，称为C2光合作用。在温暖，干燥和明亮的环境下，使用C2光合作用的植物有效，但也相当塑性，应该能够在C3和C2途径之间转移生理，以在不同的生长条件下保持效率。因此，该CTP的设计旨在表征火箭品种之间的光合作用多样性（例如，源自冷北纬度的这些品种比来自温暖南欧的温暖的品种表现出比源自温暖的南欧的品种弱？），并确定每种火箭在不同环境下的C2 VS C2 vs c2 vs c2 vs c2光合途径之间的变化。学生的目标：1。策划一系列不同的火箭品种； 2。在一系列现场试验（即意大利南部，意大利，西班牙和英国）和在受控环境条件下的一系列现场试验中，在不同的生长条件下发展了这种多样性；作为与Bakkavor的安置的一部分； 3。量化各种生长条件下各种火箭品种的生物量和风味；和4。确定在不同环境中这些火箭品种中生理的变化或保持恒定的程度，以及这如何影响产量和风味。 C2和C3生理学之间的转移将通过量化生理，解剖和13C稳定的同位素参数来评估在火箭叶中。该博士学位项目最终将确定火箭品种和环境条件，这些品种和环境条件传达产量和风味一致性，并最大程度地提高生物量和风味，以提高这种重要作物的可持续性和消费者吸引力。
