چکیده
Heat shock proteins (HSPs), molecular chaperones with many activities, are essential to plant growth, development, and stress responses. To make crops more salt- and drought-resistant, plant breeders have considered halophytic plant. Aeluropus littoralis, a halophyte monocot grass, is one potential model species to discover new stress-response genes. Here, exon/intron structure, conserved motifs/ domains, and expression patterns of HSP۱۰۰ gene family were identified in the genome of A. littoralis. This study found six unique AlHSP۱۰۰ non-repetitive genes, revealing remarkable structural and physicochemical variations between the subfamilies. Phylogenetic and motif analyses revealed that proteins from the same subfamily (AlHSP۱۰۰.۱-۴) and proteins from other subfamilies (AlHSP۱۰۰.۵-۶) have similar types, ordering, and quantities of motifs. Finally, the expression of AlHSP۱۰۰.۳ gene was analyzed using RT-qPCR under dehydration, salt, cold, and phytohormone abscisic acid stress treatments, revealed that their expression patterns vary in response to abiotic stresses. The presence of stress-dependent regulation of the HSP۱۰۰.۳ gene, as evidenced by the early response to osmotic stress and the late response to cold stress, is likely associated with the cis-regulatory elements located upstream of this gene. This study provides more valuable information to deepen our understanding of the abiotic stress responses by HSP۱۰۰ genes in A. littoralis.کلیدواژه ها
