Abstract Alternation of generations in plant life cycle provides a biological basis for natural selection occurring either the gametophyte or sporophyte phase both. Divergent biphasic could yield distinct evolutionary rates phase-specific pleiotropic genes. Here, we analyze models that deal with antagonistic and synergistic between alternative terms ratio nonsynonymous to synonymous divergence (Ka/Ks). Effects are opposite under but cumulative Under additive comparable strengths allelic...
Toona ciliata is an important timber species but recognized as endangered at level II in China. Its genetic conservation of increasing concern. Provenance trials and other breeding programs were conducted to develop seed transfer rules multiplications. Here, we investigated twenty-nine populations sampled across the natural distribution T. complex using mtDNA nrDNA ITS (ribosomal internal transcribed spacer) markers. Haplotype diversity was h = 0.190 ± 0.202 nucleotide π 0.000383 0.000536...
The prediction of genetic gain from artificial selection in a trait is important plant and animal breeding. Lush’s classical breeder’s equation (BE) widely used for this purpose, although it also applied to predicting evolution under natural selection. current application high throughput sequencing techniques potentially allows breeders at the individual gene level capture both additive non-additive effects. Here, we provide comprehensive evaluation gains multiple hierarchical levels...
Toona ciliata Roem is an important timber species in the genus of Meliaceae family and endangered due to over-cutting a low rate natural regeneration China. Although molecular markers have been applied studying population genetic diversity, absence reliable reference genome limits in-depth conservation evolutionary studies this species. Here, we reported high-quality assembly whole sequence T. ciliata. The total assembled has 520.64 Mb length anchored on 28 chromosomes (contig N50 = 4.48...
Abstract Toona ciliata is an endangered species due to over‐cutting and low natural regeneration in China. Its genetic conservation of increasing concern. However, several varieties are recognized according the leaf flower traits, which complicates T. . Here, we sequenced whole chloroplast genome sequences three samples for each four ( var. , yunnanensis pubescens henryi ) sympatry assessed their phylogenetic relationship at a fine spatial scale. The had sizes ranged from 159,546 159,617 bp...
Toona ciliata and sinensis belong to the genus of Meliaceae family are important timber species in China. T. is an endangered at level II due overcutting a low rate natural regeneration. was cultivated as economic nutritious tree for more than 2000 years. The two differ flower leaf morphological traits, reproductive systems, range size distribution. To reveal potential molecular basis these divergences, we examined similarities differences their whole genome sequences. Results indicate that...
Forest genetic conservation is typically species-specific and does not integrate interspecific interaction community structure. It mainly focuses on the theories of population quantitative genetics. This approach depicts intraspecific patterns structure derived from markers differentiation adaptive traits in provenance trials. However, it neglects possible natural forests overlooks hybridization or subspeciation. We propose that diversity a given species forest shaped by both evolutionary...
Neolamarckia cadamba (Roxb.) Bosser is a fast-growing deciduous tree species and belongs to the genus of Rubiaceae family. This has great economic medical values in addition being an important timber for multiple industrial purposes. However, few studies have examined genetic diversity population structure natural distribution this China. Here, we applied both haploid nrDNA ITS (619 bp aligned sequences) mtDNA (2 polymorphic loci) markers investigate 10 populations (239 individuals total)...
Toona ciliata is a deciduous or semi-deciduous tree species and belongs to the genus of Meliaceae family. Owing low natural regeneration over-exploitation, listed as an endangered at level II in China its conservation has received increasing concern. Here, we sampled 447 individuals from 29 populations across range-wide distribution T. complex assessed their genetic variation using two chloroplast DNA markers. The results showed that overall haplotype diversity nucleotide per site were high...
Sexual reproduction with alternative generations in a life cycle is an important feature eukaryotic evolution. Partial selfing can regulate the efficacy of purging deleterious alleles gametophyte phase and masking effect heterozygotes sporophyte phase. Here, we develop new theory to analyze how shapes fixation mutant allele that expressed or only two phases. In infinitely large population, critical rate beyond which tends be fixed under equilibrium between irreversible mutation selection...
Residual feed intake (RFI) is a measure of efficiency animals. Previous studies have identified SNPs associated with RFI. The objective this study was to compare the GBLUP model GA-BLUP included previously SNPs. nine RFI-associated were obtained from GWAS on discovery population, as preselection information. These models analysed using ASREML software 5-fold cross-validation method validation population. With genetic architecture (GA) matrix involved, which conducted SNPs, prediction...
