Fatty Acid and Associated Gene Expression Analyses of Three Tree Peony Species Reveal Key Genes for α-Linolenic Acid Synthesis in Seeds.

ABSTRACT: The increasing demand for healthy edible oil has generated the need to identify promising oil crops. Tree peony (Paeonia section Moutan DC.) is a woody oil crop with α-linolenic acid (ALA) contributing for 45% of the total fatty acid (FA) content in seeds. Molecular and genetic differences that contribute to varied FA content and composition among the wild peony species are, however, poorly understood. Analyses of FA content and composition during seed development in three tree peony species (Paeonia rockii, P. potaninii, and P. lutea) showed varied FA content among them with highest in P. rockii, followed by P. potaninii, and P. lutea. Total FA content among these species increased with seed development and reached its maximum in its final stage. Seed FA composition analysis of the three
