Identification of two new GRAS transcription factors and expression analysis of these genes in .

is a relatively new and excellent crop, and its growth is frequently threatened by abiotic stress. genes are considered to be a plant-specific transcriptional regulatory family, which is essential for controlling aboveground and root development, as well as enhancing tolerance to abiotic stress. Phylogeny, gene structure, genomic location, conserved motif, cis-element, protein interaction, and expression pattern were all comprehensively investigated in this research of the quinoa genes. According to its structure and phylogenetic characteristics, the identified quinoa 54 GRAS members were divided into 10 subgroups. The distribution of genes on 19 quinoa chromosomes is uneven, with Chr07 and Chr18 having the largest number of genes. The quinoa GRAS family's evolution has been driven by duplication and collinearity among members. Under abiotic stress, 12 selected genes showed significant differential expression. and were most sensitive to low temperatures, HO treatment highly induced the expression of , and NaCO treatment highly induced the expression of . After conducting tissue quantification, we found that some genes exhibit tissue-specific expression patterns, with and being highly expressed in stems and and being highly expressed in leaves. In summary, this work gives valuable information for a comprehensive understanding of the functional analysis of the genome's gene family and the identification of candidate genes to improve quinoa's resistance to abiotic stress.
