Abstract The Lesion Simulating Disease (LSD) genes encode a family of zinc finger proteins that are reported to play an important role in the hypersensitive response and programmed cell death (PCD) that are caused by biotic and abiotic stresses. In the present study, 117 putative LSD family members were identified in Viridiplantae. Genes with one, two, or three conserved LSD domains were identified. Proteins with three LSD domains were highly represented in the species analyzed and were present in basal organisms. Proteins with two LSD domains were identified only in the Embryophyte clade, and proteins possessing one LSD domain were highly represented in grass species. Expression analyses of Glycine max LSD (GmLSD) genes were performed by realtime quantitative polymerase chain reaction. The results indicated that GmLSD genes are not ubiquitously expressed in soybean organs and that their expression patterns are instead organ-dependent. The expression of the majority of GmLSD genes is modulated in soybean during Phakopsora pachyrhizi infection. In addition, the expression of some GmLSD genes is modulated in plants under dehydration stress. These results suggest the involvement of GmLSD genes in the response of soybean to both biotic and abiotic stresses.
