Accelerated breeding for a changing environment: genomic and physiological profiling of newly generated polyploid trees

全球气候变化威胁着森林和种植园的健康和生产力。由于树木繁殖缓慢，优良树木不能迅速适应新环境。工业合作伙伴开发了一种加速树木育种的新程序。这一过程被称为多倍体化，增加了DNA含量，并产生了可以改善植物生长和恢复力的新性状。多倍体化是植物进化的一种自然力量，它在树木育种中的常规应用具有很大的潜力。利用不同的方法，我们将研究新合成的多倍体树种在高温和干旱胁迫下的表现。

Global climate change threatens the health and productivity of forests and plantations. Because tree breeding is slow, elite trees cannot be adapted rapidly to new environments. A new procedure for accelerated tree breeding has been developed by the industry partner. The procedure, termed polyploidisation, increases DNA content and produces novel traits that can improve plant growth and resilience. Polyploidisation is a natural force in plant evolution and its routine application for tree breeding has much potential. Using diverse approaches, we will investigate how newly synthesised polyploid tree species perform under heat and drought stress.
