Characterization and expression analysis of the SPL gene family during floral development and abiotic stress in pecan (Carya illinoinensis).

ABSTRACT: SQUAMOSA promoter binding protein-like (SPL) genes are a type of plant-specific transcription factors that play crucial roles in the regulation of phase transition, floral transformation, fruit development, and various stresses. Although SPLs have been characterized in several model species, no systematic analysis has been studied in pecans, an important woody oil tree species. In this study, a total of 32 SPL genes (CiSPLs) were identified in the pecan genome. After conducting phylogenetic analysis of the conserved SBP proteins from Arabidopsis, rice, and poplar, the CiSPLs were separated into eight subgroups. The CiSPL genes within the same subgroup contained very similar exon-intron structures and conserved motifs. Nine segmentally duplic
