Abstract:
Olive (Olea europaea) is the most valuable oil and fruit crop with numerous varieties and has rich germplasm. SSRs, which are effective markers, have been used to identify different cultivars of olives. It is challenging to distinguish between cultivars and understand relationships among olive cultivars because there are so few SSR markers available, cultivar names can be confusing, and vegetative variation may develop. Comparative genomic analysis used to identify potential genes and oil biosynthesis pathways that contribute to high oil content in olive genome. In investigations of genetic diversity Sequence Repeat (SSR) or microsatellite markers have shown to be incredibly helpful tools. Approximately 100 of these markers, the bulk of which are di or tri-nucleotide, have been discovered in the Olea europaea to date. Due to length differences and imperfect motifs, microsatellites, a kind of repetitive DNA, may be targeted by occurring biochemical processes in a cell. Numerous species have undergone substantial research on the mutational processes driving this type of genomic diversity. However, little is known about the mysterious effects of polidization, an evolutionary process of genomic material duplication that primarily affects plants. There has been a relatively limited genome-scale investigation of oil biosynthesis in cultivated olive species, particularly in Pakistan. So, chromosome-scale genomic assemblies of 10 olive cultivars were performed in this study. The comparative genomics technique was used to explore the distinctive correlations between repeat density, motif imperfection analysis, and gene expression profiling of the oil biosynthesis genes in the olive genome. This analysis of the conservation imprints of microsatellites in the evolution of the olive was also made possible. According to our findings, the abundance of imperfect microsatellites in the genome was closely associated with motif imperfection in repeat length.
