Preliminary experiments at UoN suggest that foliar application of the succinate dehydrogenase inhibitor (SDHI) fungicide penthiopyrad confers rooting benefits on wheat and oilseed rape. In both species, root dry weights in pot experiments increased in a dose-dependent manner. The mode of action of penthiopyrad in increasing root biomass is currently unknown but is not linked to SDHI fungicide activity as other foliar applied SDHIs do not show this. The phytohormone auxin is a key determinant of root growth through which penthiopyrad may act - a pilot experiment using auxin reporters in the model species Arabidopsis thaliana suggests that root auxin levels are reduced following application. This project has two main objectives: examination of the rooting benefits of penthiopyrad and determination of the mode of action. This will be achieved using a combination of pharmacological, genetic, molecular and cell biological approaches.

在UoN的初步实验表明，叶面施用琥珀酸脱氢酶抑制剂（SDHI）杀菌剂吡噻菌胺对小麦和油菜的生根有益。在这两个物种中，根干重在盆栽实验中以剂量依赖性的方式增加。吡噻菌胺在增加根生物量方面的作用模式目前尚不清楚，但与SDHI杀真菌剂活性无关，因为其他叶面施用的SDHI没有显示出这一点。植物激素生长素是根生长的关键决定因素，吡硫草胺可能通过其发挥作用--在模式物种拟南芥中使用生长素报告基因的试点实验表明，施用后根生长素水平会降低。该项目有两个主要目标：检查吡噻菌胺的生根效益和确定其作用方式。这将使用药理学、遗传学、分子和细胞生物学方法的组合来实现。
