Final Report - ANAVACO (Analysis of natural variation for cold tolerance in the model plant species Arabidopsis thaliana)

Project ID: 220833
Funded under: FP7-PEOPLE


This is the final report of the AVANCO project, which is funded under the European Commission (EC) Seventh Framework Programme (FP7). The project set out to uncover the genetic variants that are the underlying cause of the natural variation in tolerance to sub-zero temperatures. It employed a genome-wide mapping study — GWAS conducted on over 500 Arabidopsis thaliana plants species. A phenotyping protocol was used to expose young plants to low temperatures over time, before being allowed to grow in a warmer environment. Considerable variation in freezing tolerance was observed on over 250 000 Single Nucleotide Polymorphisms (SNPs).

GWA and QTL mapping were successful in detecting genes or genomic regions with an underlying freezing tolerance. Freezing tolerance has gained interest from plant-breeding companies which must respond to the growing world population by drastically increasing food production across all crop species. It is expected this project will enhance knowledge of the genetic basis of freezing tolerance in Arabidopsis thaliana.
