Transcription factor Wrinkled (WRI) 1 is associated with triacylglycerol (TAG) biosynthesis and accumulation in plant tissues. In avocado (Persea americana), a basal angiosperm, four WRI orthologs (1-4) were identified by transcriptome studies and the gene expression of WRI1, 2 and 3 was associated with TAG accumulation in mesocarp tissue. Therefore, it is hypothesized that putative PaWRI1, 2 and 3 but not PaWRI4 are responsible for TAG synthesis in non-seed tissues. To this extent, various in silico analyses were performed to identify similarities and distinct features of putative WRI genes in basal angiosperm relative to maize and Arabidopsis, a monocot and dicot respectively. Predicted structural comparison of these orthologs is expected to reveal the distinct features of avocado WRI paralogs that are associated with the regulation of oil biosynthesis in non-seed tissues.
