Saline-alkali stress was a common stress that seriously affected plant growth and productivity. Saline-alkali soil contained the characteristics of high salinity and high pH value, which could cause comprehensive damage such as osmotic stress, ion toxicity, high pH, and HCO^3-/CO₃^2- stress. In our study, 18 <i>PaALDH</i> genes were identified in sweet cherry genome, and their gene structures, phylogenetic analysis, chromosome localization, and promoter <i>cis</i>-acting elements were analyzedPhysiology and molecular biology of plants : an international journal of functional plant biologyGenome-wide identification and expression analysis of the ALDH gene family and functional analysis of &lt;i&gt;PaALDH17&lt;/i&gt; in &lt;i&gt;Prunus avium&lt;/i&gt;.PMC1108740221CX6NM10831960581Li SZhang ZWang WWang XWang YZhang QfalseGenome-wide identification and expression analysis of the ALDH gene family and functional analysis of &lt;i&gt;PaALDH17&lt;/i&gt; in &lt;i&gt;Prunus avium&lt;/i&gt;.ALDH (Aldehyde dehydrogenase), as an enzyme that encodes the dehydroxidization of aldehydes into corresponding carboxylic acids, played an important role inregulating gene expression in response to many kinds of biotic and abiotic stress, including saline-alkali stress.
