T. turgidum ssp. dicoccoides Thell is also named Triticum dicoccoides sometimes. It is a tetraploid wheat with 28 chromosomes (2n = 4x = 28, AABB). It is considered to be the wild form of all domesticated emmer wheats, i.e. wild emmer wheat (WEW). The species has two homologous sets of chromosomes (BBAA) thought to have arisen from spontaneous hybridization between two diploid donor species. The A genome conferred by the current species T. urartu is considered the donor species, while the donor of the B genome is unknown but was likely a species closely related to modern Aegilops speltoides Tausch (2n = 14; SS). Wild emmer is considered the progenitor of all modern cultivated tetraploid wheat.

The WEW genome was sequenced by an international collaboration led by wheat researchers in Tel Aviv University, Israel, using then cutting-edge software DenovoMAGIC2 produced by the company NRGene (Avni et al. Science 2017).

Gene Expression Data: 1 RNA-Seq study and 17 RNA-Seq samples are currently available on WheatGene.

Raw RNA-Seq data was retrieved from the NCBI and processed by the WheatGene team to estimate the TPM expression patters. Such data belongs to the following study:
