Comparative transcriptomic, proteomic, and amino acid content analyses of quinoa (Chenopodium quinoa) seed accessions from diverse geographic locations.

ABSTRACT:

Background

Quinoa (Chenopodium quinoa), a pseudocereal native to the Andean regions, is mainly characterized by the quality and nutritional value of its proteins due to an excellent balance of essential amino acids. To identify nutritional attributes and compare different germplasm accessions, we conducted comparative transcriptomic and proteomic studies on a total of five quinoa accessions. These include four accessions from different genetic groups representing dry valleys, dry highlands, transition areas, and humid valleys in the Northwest Argentina region (NWA), as well as QQ74, a sequenced Chilean coastal accession.

Results

We analyzed the quinoa seed transcriptome of four different accessions by aligning the RNA-seq results with the second version of the QQ74 genome (Q
