The decline in performance at advanced ages, senescence, affects life quality, lifespan and productivity. It is believed that this phenomenon is universal, including all species from microbes to humans. Yet, some plants do not exhibit senescence. This project will identify the mechanisms that enable plants to escape senescence. Using a unique global demographic database, the project will determine whether, how and when senescence has evolved across 850 plant species. It will also experimentally test how drought, nutrients and resprouting affect senescence in two mallee Eucalyptus species in the Simpson Desert. This research will provide new insights into the evolution of senescence and will elucidate how some plants escape a supposedly unavoidable fate.

老年人的表现下降，衰老，影响生活质量，寿命和生产力。人们认为这种现象是普遍的，包括从微生物到人类的所有物种。然而，有些植物并没有表现出衰老。该项目将确定使植物逃避衰老的机制。利用一个独特的全球人口数据库，该项目将确定850种植物是否、如何以及何时衰老。它还将通过实验测试干旱、营养和重新发芽如何影响辛普森沙漠中两种桉树的衰老。这项研究将为衰老的进化提供新的见解，并将阐明一些植物如何逃脱所谓不可避免的命运。
