Rosa sect. Chinenses (Rosaceae) is an important parent of modern rose that widely distributed throughout China and plays role in breeding molecular biological research. R. has variable morphological traits mixed germplasm. However, the taxonomic status genetic background varieties remain unclear. In this study, we collected germplasm resources from with different traits. Simple sequence repeat (SSR) markers, chloroplast single copy nuclear markers were used to explore these resources. We described origin hybridization by combining markers. The results showed flower hip species significantly different. SSR analysis two wild type have backgrounds. double petal could be hybrids varieties. A phylogenetic maternal inheritance had origins. To some extent, variation reflects influence cultivation process. This study emphasizes vary their characteristics. Therefore, analyzing provide insight into highly heterozygous species.

Petal blotch is a specific flower color pattern commonly found in angiosperm families. In particular, Rosa persica characterized by dark red blotches at the base of yellow petals. Modern rose cultivars with inherited trait from R. persica. Therefore, understanding mechanism for formation crucial breeding various patterns. this study, metabolites and genes responsible were identified first time through metabolomic transcriptomic analyses using LC-MS/MS RNA-seq. A total 157 flavonoids identified, 7 anthocyanins as major flavonoids, namely, cyanidin 3-O-(6″-O-malonyl) glucoside 5-O-glucoside, cyanidin-3-O-glucoside, 3-O-galactoside, O-rutinoside-O-malonylglucoside, pelargonidin 3-O-glucoside, 3,5-O-diglucoside, peonidin contributing to pigmentation darkening parts persica, whereas carotenoids predominantly influenced non-blotch parts. Zeaxanthin antheraxanthin mainly contributed petals semi-open full bloom stages. The expression levels two 4-coumarate: CoA ligase (Rbe014123 Rbe028518), dihydroflavonol 4-reductase gene (Rbe013916), anthocyanidin synthase (Rbe016466), UDP-flavonoid glucosyltransferase (Rbe026328) indicated that they might be key structural affecting petal blotch.

Abstract Rose ( Rosa ) is a prominent ornamental plant that holds substantial economic and social significance. Roses originating from different regions exhibit intricate phenotypic genetic characteristics, but the majority of rose resources are poorly characterized. In this study, 192 genotypes genus were examined using 33 traits 10 pairs SSR markers. Compared to wild species, both old garden modern roses exhibited significant level diversity, with flower color having highest degree diversity style morphology lowest diversity. This phenomenon may be attributed limited utilization due their simpler frequent molecular infiltration between roses. Following inaugural comprehensive evaluation employing principal component analysis, R. chinensis ‘Zihongxiang’, hybrida ‘Burgundy Iceberg’, ‘Conrad F. Meyer’, rugosa ‘Gaohong’ floribunda ‘Sheherazad’ selected as core germplasm for future breeding. Moreover, three tetraploid roses, namely ‘Midnight Blue’, ‘Sheherazad’, ‘Couture Tilia’, differences in profiles reciprocally intercrossed. Ultimately, two populations obtained exhibiting variation size, annual stem color, pickle density, leaf number. Furthermore, our results indicated diameter, height, petal width, number potentially controlled by major-effect loci. conclusion, study provides novel insights into evolutionary patterns resources. It paves way identifying carry distinct characteristics possess immense value breeding varieties future.

Abstract In Rosaceae species, two gametophytic self-incompatibility (GSI) mechanisms are described, the Prunus self-recognition system and Maleae ( Malus/Pyrus/Sorbus ) non-self- recognition system. both systems pistil component is a S-RNase gene, but from distinct phylogenetic lineages. The pollen component, always F-box gene(s), in case of single there multiple genes. Previously, Rosa S -locus was mapped on chromosome 3, three putative genes were identified R. chinensis ‘Old Blush’ genome. Here, we show that these do not belong to region. Using multiflora genomes approach, belongs -lineage. Expression patterns support this gene as being -pistil. This here also moschata , arvensis minutifolia low coverage genomes, allowing identification positively selected amino acid sites, thus, further supporting . Furthermore, genotype–phenotype association experiments For -pollen GSI find evidence for genes, expected expression pattern, diversifying selection at within an -haplotype. Thus, has non-self-recognition system, like despite -pistil belonging lineage. These findings discussed context evolution.

The investigation of quantitative trait loci (QTL) is an essential component in our understanding how organisms vary phenotypically. However, many important crop species are polyploid (carrying more than two copies each chromosome), requiring specialized tools for such analyses. Moreover, deciphering meiotic processes at higher ploidy levels not straightforward, but necessary to understand the reproductive dynamics these species, or uncover potential barriers their genetic improvement.Here, we present polyqtlR, a novel software tool facilitate analyses (auto)polyploid crops.

Introduction Breeding roses with ideal ornamental characteristics such as beautiful flowers, a pleasant fragrance, and attractive growth habits is complex time-consuming. This process can be improved accelerated through the use of molecular markers. Methods We conducted genome-wide association study on nine traits in using RhWagSNP chip across panel 285 cultivars varieties. Significant marker-trait associations found for major quantitative trait loci were further validated single-marker analyses PACE technology independent panels up to 182 genotypes. Results For six traits— ‘Young shoot: intensity anthocyanin coloration’, ‘Stem: number prickles’, ‘Leaf: glossiness upper side’, ‘Flower: petals’, fragrance’, ‘Petal: length’—we identified QTLs. Conversely, we unable validate coloration’ green color no significant GWAS size’. Loci that affect petal size, fragrance have been previously studied. able detect associated markers increased effect sizes all three traits. Even greater effects observed when combined from fragrance. Discussion Associated some analysed largely colocalise QTL biparental populations. Our validation strategy an alternative marker different environments supports robustness our data, irrespective limited sizes. which could associations, data interpreted cautiously indicating high complexity inheritance, few large-effect QTLs influencing other four traits, either genetic and/or stronger environmental may confounded analyses. believe presented here serve valuable tools marker-assisted selection analysis analysed.
