Characterization of Japanese Plum (Prunus salicina) PsMYB10 Alleles Reveals Structural Variation and Polymorphisms Correlating With Fruit Skin Color

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

Published: June 8, 2021

The red to blue hue of plant organs is caused due anthocyanins, which are water-soluble flavonoid pigments. accumulation these pigments regulated by a complex R2R3-MYB transcription factors (TFs), basic-helix-loop-helix (bHLH), and WD-repeat (WDR) proteins (MBW complex). In Rosaceae species, R2R3-MYBs, particularly MYB10 genes, responsible for part the natural variation in anthocyanin colors. Japanese plum cultivars, hybrids Prunus salicina , have high variability color pattern, going from yellow-green purple-blue, probably as result interspecific hybridization origin crop. Because such variability, can be considered an excellent model study determination fruit tree species. Here, we cloned characterized alleles PsMYB10 genes linkage group LG3 region where quantitative trait loci (QTLs) organ been mapped other Allele segregation biparental populations well panel varieties, combined with whole-genome sequence two varieties contrasting color, allowed organization into haplotypes. With help this strategy, were assigned at least three copies PsMYB10.1 identified some varieties. total, observed six haplotypes, able characterize 91.36% cultivars. addition, found highly associated anthocyanin-less skin. Their expression during development confirms their role skin coloration. provide efficient molecular marker early selection colored or non-colored fruits breeding programs.

Pepino (Solanum muricatum) Metabolic Profiles and Soil Nutrient Association Analysis in Three Growing Sites on the Loess Plateau of Northwestern China

Metabolites, Journal Year: 2022, Volume and Issue: 12(10), P. 885 - 885

Published: Sept. 20, 2022

Different soil nutrients affect the accumulation characteristics of plant metabolites. To investigate differences among metabolites pepino grown in greenhouses on Loess Plateau northwest China, we investigated main and their correlation with A total 269 were identified using UPLC-QTOF-MS to detect fruits from three major growing regions analyze differential distribution characteristics. 99 these substances differed areas, classes were, order number: amino acids derivatives, nucleotides organic acids, alkaloids, vitamins, saccharides alcohols, phenolic lipids others. An environmental factor analysis as most significant differentiator. Five nutrient indicators: TN (total nitrogen), TP phosphorus), AP (available AK potassium), OM (organic matter), exhibited sites. Metabolite association redundancy (RDA) Mantel test indicated that contributed alkaloids while inhibiting vitamins coagulation biosynthesis. Moreover, associated highest and, acids. Consequently, reflected metabolite variability. This study clarified variability relationship between planting areas China. It provides a theoretical basis for subsequent development Pepino's nutritional value cultivation management.

Multi-Omic Approaches to Investigate Molecular Mechanisms in Peach Post-Harvest Ripening

Agriculture, Journal Year: 2022, Volume and Issue: 12(4), P. 553 - 553

Published: April 13, 2022

Peach post-harvest ripening is a complex developmental process controlled by plethora of genetic and epigenetic factors. Specifically, it leads to protein, lipid nucleic acid degradation, all resulting in cell death. Substantial research has been directed at investigating peach regulatory mechanisms underlying genomic, metabolomic transcriptomic modifications occurring during this stage, much progress made thanks the advent Next Generation Sequencing technologies. This review focused on latest multi-omics studies, with aim highlighting most significant results further regulation key genes involved processes related physiology. By offering an exhaustive overview omics profiles, provides comprehensive description gene expression changes their correlation stages, including some treatments, as well volatile organic compound modifications. However, present work highlights that, due complexity process, recent investigations do not elucidate molecular mechanisms, making studies still necessary. For reason, points for future activities innovative breeding programs are discussed, relying trusted multi-omic approaches.
