Genetic maps have become significantly important in understanding markers, breeding, association genetics, map-assisted gene cloning, gene mining, and mapping of quantitative trait loci (QTLs) (Golestan Hashemi et al. 2015). In our study, we integrated two genetic maps from the D genome of the diploid cotton with a mapping size of 188 F2:step three population. The first genetic map (Map A) was composed of a genetic cross between G. klotzschianum (female parent) and G. davidsonii (male parent) while the second genetic map (Map B) was developed from G. thurberi (female parent) and G. trilobum (male parent). Map B had a higher number of markers linked and a smaller average distance as compared with map A. This map could play a fundamental role in the analysis of QTLs. In the construction of the consensus map, more markers were contributed by map B as compared with map A. Inconsistencies of marker order including the translocation or inversions between individual markers in consensus maps were observed especially on markers that were closely linked together in the SDR of Chromosome D502–2. 2012).
The segregation distortion among the three maps ranged from 15.8% (map A) to 22.2% (map B). Segregation distorted markers have previously been studied in various plants (Takumi et al. 2013). The study of segregation distortion is significant because distorted markers may be linked to genes or traits of interest, these genes may be beneficial or lethal to organisms. Therefore, it’s important to include the segregation distortion markers in the construction of genetic maps since the exclusion of such markers could cause bias of the data and result in the loss of significant genetic information. In our study, we examined the trend of segregation distortion within Chromosome D502 and D507. We observed that both chromosomes had higher segregation distorted markers. Chromosome D502 had the least mapped markers with a higher percentage of segregation distortion ranging from 42.9% to 76.1% in the three genetic maps. Similar results have been observed in cotton (Li et al. 2007; Khan et al. 2016; Shang et al. 2016). The two chromosomes also showed SDR which was skewed towards a specific allele. These SDRs may be due to pre- or post-zygotic selection and chromosome loss or rearrangements.

We noticed you to 29 genetics were not disrupted from the introns (intronless), intronless genes consist of one exon plus don’t consist of introns from the start to the conclusion neither in UTR otherwise Dvds regions (Yan et al. 2016). The brand new intronless genes are recognized to bring the brand new results away from transcription initiation and you may elongation when you look at the spliced genes (Sakharkar et al. 2006). Its isoelectric area (pI) viewpoints varied regarding each other acid so you can first protein. Brand new pI values are known to impact the solubility off healthy protein molecules; hence proteins is actually less dissolvable if the pH of the solution is at their isoelectric part (Dawes mais aussi al. 1994). Every protein was in fact observed for a GRAVY really worth lower than no, proving which they was hydrophilic. Hydrophilic healthy protein possess a premier solubility, hence such protein would-be to try out a significant part inside desiccation tolerance (Hundert), while having help in enzymatic facts involved in the biochemical processes.
