abstract = {The domestication of crops, coupled with agroecosystem
development, is associated with major environmental changes
and provides an ideal model of phenotypic plasticity. Here,
we examined 32 genotypes of three tetraploid wheat (Triticum
turgidum L.) subspecies, wild emmer, emmer, and durum wheat,
which are representative of the key stages in the
domestication of tetraploid wheat. We developed a pipeline
that integrates RNA-Seq data and population genomics to
assess gene expression plasticity and identify selection
signatures under diverse nitrogen availability conditions.
Our analysis revealed differing gene expression responses to
nitrogen availability across primary (wild emmer to emmer)
and secondary (emmer to durum wheat) domestication. Notably,
nitrogen triggered the expression of twice as many genes in
durum wheat compared to that in emmer and wild emmer. Unique
selection signatures were identified at each stage: primary
domestication mainly influenced genes related to biotic
interactions, whereas secondary domestication affected genes
related to amino acid metabolism, in particular lysine.
Selection signatures were found in differentially expressed
genes (DEGs), notably those associated with nitrogen
metabolism, such as the gene encoding glutamate
dehydrogenase (GDH). Overall, our study highlights the
pivotal role of nitrogen availability in the domestication
and adaptive responses of a major food crop, with varying
effects across different traits and growth conditions.},
