With the chromosome 4, all of the about three QTLs was on 66
Field plots appearing the results of marker genotypic classes (AAAA, AAAB, AABB, ABBB, BBBB) of cuatro candidate SNPs on the tuber glucose attention (GLU); bud-avoid fry color (FBE); stem-tuber fry colour (FSE); ID, Idaho
The co-localization off numerous QTLs in the readiness locus part inside studies is consistent with the noticed activities out-of phenotypic correlations. 01) with several attributes overlapping a comparable hereditary reputation (Fig. 1). As an instance, EBID11 and you can VWID11 ratings both demonstrated a strong bad correlation that have MAT95ID and you may MAT120ID. This trend can get give an explanation for significant effect QTL with later maturity directly regarding the defer onset of VW and you can EB, or alternatively, early readiness ultimately causing early onset of VW and you can EB. A comparatively high relationship has also been seen between vine maturity and you can gains practice, with very early maturity with the so much more spread progress habit. Alternatively, a low relationship (r ? 0.2) ranging from vine readiness and you will both tuber glucose amount and you can bud-end fry colour are in keeping with different types into the QTL consequences.
Tuber sugar, bud-prevent and you will stem-avoid fry colour
Including chromosome 5, extreme QTLs getting glucose, bud-stop and you can stem-end fry colour was basically perceived within the overlapping regions of chromosomes cuatro, 6, ten, and you will eleven. 0 cM on LOD score anywhere between cuatro.five to six.0 (Table 3, Fig. 4). These types of QTLs said ranging from eight.2 and eleven.3% of the trait difference. Studies of different simple activities indicated an individual top-fitting design for everybody three faculties, which have a two fold-simplex allele (AAAB ? AAAB) to the homologous chromosomes H2 and you will H5 out-of RGR and you will Public relations, respectively (Desk step three, Most file 8: Profile S4). Having sugar, the fresh new B allele are with the highest glucose quantity, while to own bud-prevent and stalk-end fry color, the existence of the new B allele conveyed lower reflectance viewpoints (Fig. 3b).
LOD get shipping out of QTLs for a few characteristics along side a dozen potato chromosomes (Chr). Abbreviations try as with Fig. step 1
A candidate SNP for a double-simplex configuration on H2 and H5 is solcap_c2_12976 at position 67.4 cM. On the reference PGSC v4.03 Pseudomolecules, this SNP maps to the long arm of chromosome 4 at position 69.1 Mb on the F-box and WD40 domain protein gene (PGSC0003DMG400003339), which is close (< 2 Mb) to several genes associated with starch/sugar inter-conversion as annotated in the potato reference genome, and/or associated with tuber quality traits . They include alpha amylase (AMY-4/1 PGSC0003DMG400007974, AMY-4/2 PGSC0003DMG400009891), hexose transporter (HT-4/3, PGSC0003DMG400009994), invertase (NV-4, PGSC0003DMG400009936), and starch branching enzyme I (SBE I, PGSC0003DMG400009981).
On chromosome 6, significant QTLs mapped at 53 cM for glucose and at 43 cM for FBE and SBE, respectively. The LOD profiles ranged from 5.4 to 7.6 and explained between 10.8 and 16.1% of the trait variance Reise-Dating-Webseite, respectively (Table 3, Additional file 9: Figure S5). The best model for all three traits was a double-simplex configuration with allele effects on H2 and H5. As in chromosome 4, the presence of the B alleles was associated with an increase in glucose concentration and a decrease in reflectance readings (Fig. 3c). There are four candidate SNPs with a double simplex configuration nearby (solcap_snp_c2_33777, solcap_snp_c1_10130, solcap_snp_c2_5769, solcap_snp_c2_56145, c1_3003). All were significantly (P-value < 0.0001) associated with the mean trait values, however, solcap_snp_c2_56145 had on average the highest percent of variance explained (9% to 16%). The SNP solcap_snp_c2_56145 maps at position 51.4 Mb of the potato reference genome on the ATP binding protein gene PGSC0003DMG400033089. This SNP is located in a region (
7 Mb) which includes several genes from the starch/sugar inter-transformation in addition to hexokinase (HXK-6, PGSC0003DMG400016521), fructokinase (FRK-6/1, PGSC0003DMG400027017, FRK-6/dos, PGSC0003DMG400026916), and invertase (INV-na-6/1, PGSC0003DMG400026107, INV-6/dos, PGSC0003DMG400033142) genes.
