Genome-wide identification of the PLD gene family and its response to multiple abiotic stresses in soybean (Glycine max).

ABSTRACT: Phospholipase D (PLD) is a crucial enzyme hydrolyzing phospholipids to produce lipid messengers, which play pivotal roles in plant growth and adaptation to environmental stresses. However, a comprehensive characterization of the PLD gene family in soybean (Glycine max), particularly its functional relevance to nutrient deficiencies, remains limited. We identified 25 GmPLD genes in the soybean genome, all containing the conserved HKD catalytic domain. Phylogenetic analysis classified them into seven subfamilies, including two novelly identified φ subtypes (GmPLDφ1/2). Expression profiling revealed tissue-specific patterns, with certain genes highly expressed in reproductive organs, and single-cell RNA-seq further unveiled their spatial expression heterogeneity. Under abiotic stresses, disti
