Hur vet träden att det är höst?
Title [en]
How do trees know it is autumn?
Abstract [sv]
Autumnal senescence may be the plant developmental process that attracts most attention by the public but least attention by scientists. Every autumn deciduous trees need to shed their leaves and prepare for the winter. We will capitalize on our previous studies on autumnal senescence in aspen, and the genomic tools that we have been developed for Populus, in particular the full genome sequence. We will ask three major questions. 1) How do nitrogen and carbon status influence onset of senescence? 2) Which genes are responsible for the variation in autumn phenology traits? 3) Can artificial microRNAs be used to prove allele functions in an heterozygous organism and 4) Is there a epigenetic control of autumnal senescence? The results will be important both since phenology is a very important trait for the tree, but also since we use phenology traits to develop the methods to identify the genetic basis of important traits in natural tree populations.
