000201163 520__ $$aThe process of domestication has led to dramatic morphological and physiological changes in crop species due to adaptation to cultivation and to the needs of farmers. To investigate the phenotypic architecture of shoot- and root-related traits and quantify the impact of domestication and post-domestication, we examined a collection of 36 wheat genotypes under optimal and nitrogen-starved conditions. These represented three taxa that correspond to key steps in the recent evolution of tetraploid wheat (i.e., wild emmer, emmer, and durum wheat). Overall, nitrogen starvation reduced shoot growth of all genotypes, while it induced the opposite effect on root traits quantified using the automated phenotyping platform GROWSCREEN-Rhizo. We observed an overall increase in all shoot and root growth traits from wild emmer to durum wheat, while emmer was generally very similar to wild emmer, but intermediate between these two subspecies. While the differences in phenotypic diversity due to the effects of domestication were not significant, the post-domestication transition from emmer to durum wheat was marked by a large and significant decrease in the coefficient of variation. In particular, this reduction was very strong at optimal condition, and less intense under nitrogen starvation. Moreover, while at optimal condition both root and shoot traits showed significantly reduced diversity due to post-domestication, under nitrogen starvation the reduced diversity was significant only for shoot traits. Overall, a considerable amount of phenotypic variation was observed in wild emmer and emmer which could be exploited for the development of pre-breeding strategies.
