Despite comprising a small component of sunlight, UV-B wavelengths (280-315 nm) regulate a diverse array of regulatory processes in plants, including growth, metabolite content and resistance to pests and diseases. UV-B is attenuated by common greenhouse materials such as glass and polycarbonate and is therefore depleted in many commercial growing environments. Plant aesthetic quality, robustness and shelf life are fundamental to the glasshouse crops industry. We have previously shown that can UV-B can reduce plant height and increase leaf antioxidant content in coriander, thereby improving the quality this major selling herb. UV-B supplementation is, however, economically and environmentally undesirable on a large scale. A number of novel glasshouse materials are now available which transmit UV-B. The impact of these materials on potted herb quality has not been assessed.This project aims to combine fundamental environmental signalling in Arabidopsis with translational crop science. The role of UV-B in enhancing plant tolerance to abiotic stress will be investigated in the model species, Arabidopsis thaliana, using a range of physiological and molecular techniques. Together with our industrial partner, Vitacress, we additionally aim to compare the growth, development and abiotic stress tolerance of coriander and basil plants grown under UV-B-attenuating and transmitting glass. This project will require the student to spend time at the Vitacress site, in Chichester, West Sussex.

尽管紫外线B波长（280-315纳米）只占阳光的一小部分，但它调节植物的多种调节过程，包括生长、代谢物含量以及对害虫和疾病的抵抗力。UV-B被普通的温室材料如玻璃和聚碳酸酯减弱，因此在许多商业种植环境中被耗尽。植物的美学品质、健壮性和保质期是温室作物产业的基础。我们以前已经表明，可以UV-B可以降低植物高度和提高香菜叶片抗氧化剂含量，从而提高质量，这种主要销售herb. UV-B补充，但是，在经济和环境上不可取的大规模。现在有许多新的温室材料可以传输UV-B。这些材料对盆栽草本植物质量的影响还没有被评估。这个项目旨在将拟南芥中的基本环境信号与转化作物科学相结合。将利用一系列生理和分子技术，在模式物种拟南芥中研究UV-B在增强植物对非生物胁迫的耐受性方面的作用。与我们的工业合作伙伴Vitacress一起，我们还旨在比较生长在UV-B衰减和透射玻璃下的香菜和罗勒植物的生长，发育和非生物胁迫耐受性。这个项目将要求学生花时间在Vitacress网站，在奇切斯特，西萨塞克斯。
