Synteny-Based Development of CAPS Markers Linked to the Sweet kernel LOCUS, Controlling Amygdalin Accumulation in Almond (Prunus dulcis (Mill.) D.A.Webb)

Abstract: The bitterness and toxicity of wild-type seeds of Prunoideae is due to the cyanogenic glucoside amygdalin. In cultivated almond (Prunus dulcis (Mill.) D.A. Webb), a dominant mutation at the Sk locus prevents amygdalin accumulation and thus results in edible sweet kernels. Here, we exploited sequence similarity and synteny between the genomes of almond and peach (Prunus persica (L.) Batsch) to identify cleaved amplified polymorphic sequence (CAPS) molecular markers linked to the Sk locus. A segregant F1 populat… Show more

“…Conserved synteny is important to plant breeding because it can be exploited to identify molecular markers linked to agronomically relevant traits between related species. A recent example of synteny-based development of molecular markers was done between peach and almond [62]. Therefore, based on the synteny pattern observed between Prunus species we tried to identify SNPs mapped in Japanese plum in genes localized in the V2.1 peach genome.…”

“…With this scope, a classification of the genitor cultivars into homozygous or heterozygous for the sweet character is necessary. At present, the genotype of almond cultivars and selections is deduced after crossing by recording the phenotype of their descendants through kernel tasting, and quantifying the seedlings with sweet and bitter kernel [ 12 , 20 ], because molecular markers are not well developed yet to be useful [ 17 , 21 ]. This implies a long waiting time until cropping (3–4 years).…”
