Xylella fastidiosa is a globally important bacterial pathogen that attacks many plants of economic importance. Initially it was restricted to the Americas, but in 2013 it was detected in Lecce, Italy in 2013. Since the initial outbreak, it has invaded large swathes of olives in southern Italy, and is of great concern throughout Mediterranean basin and beyond. Exploring the mechanisms by which the bacterium grows within the host plant, forming a biofilm, is critical for our understanding future control methods. This project will develop mathematical models of biofilm and associated plant disease spread related to Xylella fastidiosa.

苛养木杆菌是一种全球性的重要细菌病原体，可侵染许多具有重要经济价值的植物。最初它仅限于美洲，但2013年在意大利莱切被检测到。自最初爆发以来，它已侵入意大利南部的大片橄榄，并在整个地中海盆地和其他地区引起极大关注。探索细菌在宿主植物中生长的机制，形成生物膜，对于我们理解未来的控制方法至关重要。该项目将开发与苛养木杆菌相关的生物膜和相关植物疾病传播的数学模型。
