in mining candidate genes related to oil palm fatty acids through candidate gene association analysis.
In this study, 52 oil palm fatty acid anabolic related genes were identified through oil palm genome GO annotation, and 225 pairs of IP (Intron Polymorphism) primers were designed based on intron polymorphism, and based on candidate gene association analysis, 13 IP markers were significantly associated
with fatty acid content changes.
The development of these IP markers contributes to the genetic improvement
of fatty acid composition in oil palms.
Oil palm is an important tropical woody oil crop and biomass energy forest, the main product of palm oil is derived from the pulp (mesocarp), the composition is palmitic acid and oleic acid (about 1:1).
With the prominence of edible oil safety issues, unsaturated fatty acids such as oleic acid and linoleic acid have attracted increasing attention
.
Analysis of fatty acid components in natural populations of oil palm showed that oleic acid content was negatively correlated with palmitic acid (r=-0.
53).
This indicates that a decline in palmitic acid content may lead to an increase in oleic acid content, and palm oil is feasible to become a high-quality edible oil
.
In this study, the association between the intron polymorphism of related genes in the oil palm population and the phenotypic variation of fatty acid component content was analyzed, and fatty acid-related candidate genes such as palmitic acid and linoleic acid were excavated, and different tissue sites such as peel and kernel were quantitatively verified
in different stages of development.
The results provide a theoretical basis
for increasing the content of oleic acid, linoleic acid and reducing the content of palmitic acid in oil palm breeding in the future.
