“…United Nations, Corporate Statistical Database (FAOSTAT) 2019, retrieved January 14, 2021). Commercial breeding for red raspberry (Rubus idaeus) began about 200 years ago, and most of the currently available cultivars share the same germplasm pedigree dating back to the late 1800s and early 1900s (Jennings, 2018).…”

“…Raspberries are valued for their distinctive flavour and colour and raspberry fruit breeding has widened its focus from traits associated with agronomic performance and disease resistance towards those associated with fruit sensory quality (Jennings, 2018 ; Jennings et al, 2016 ) and potential health benefits (e.g., Mazzoni et al, 2016 ). The potential health benefits of raspberries have been associated with their polyphenol content and composition (e.g., Hancock et al, 2018 ).…”

Objective The objective of this study was to investigate the genetic control of polyphenol accumulation in red raspberry (Rubus idaeus L). Methods The levels of total anthocyanins and 37 individual polyphenol metabolites were measured over three years in a raspberry biparental mapping population. Quantitative trait loci (QTLs) for these traits were mapped onto a high-density SNP linkage map. Results At least one QTL was detected for each trait, with good consistency among the years. On four linkage groups (LG), there were major QTLs affecting several metabolites. On LG1, a QTL had large effects on anthocyanins and flavonols containing a rutinoside or rhamnose group. On LG4, a QTL had large effects on several flavonols and on LG5 and LG6 QTLs had large effects on ellagic acid derivatives. Smaller QTLs were found on LG2 and LG3. Conclusion The identification of robust QTLs for key polyphenols in raspberry provides great potential for marker-assisted breeding for improved levels of potentially health beneficial components.

“…The species is diploid (2n = 2x = 14) of the subgenus Idaeobatus (VanBuren et al 2018a). Breeding of this species began in the early 21st century at the USDA ARS New York State Agricultural Experiment Station in Corvallis, OR and in Beltsville, MD, and with New Zealand HortResearch Inc (Jennings 2018). Molecular improvement for fruit traits was hampered by the lack of a high quality reference genome (Jibran et al 2018).…”

WRKY transcription factors regulate several biological processes in plants, including responses to biotic stresses and tolerance to abiotic stresses, and are part of a gene superfamily in higher plants. There are many studies on the functions of WRKY proteins in several model species, aiming at identification and functional characterization, but there has not yet been a comprehensive analysis of the RoWRKY protein family in black raspberry (Rubus occidentalis L.) as shown here. In this study, the investigation of the complete genome of the black raspberry identified 62 RoWRKY genes that were evaluated and are unevenly distributed in all seven chromosomes. The proteins encoded by these genes were classified into four groups (I, II, III and IV), with those of group II divided into five subgroups (IIa - IIe) based on their conserved domains and zinc finger domain types. Motif analysis showed that all RoWRKYs contained one or two WRKY domains and that proteins from the same group had similar motif compositions. Five pairs of RoWRKY genes in segmental duplication and two pairs in tandem duplication were detected. Analysis of the structure of RoWRKY genes showed that they have 1–11 introns, with most RoWRKY genes consisting of two introns and three exons. A cis element analysis showed that all promoters of the RoWRKYs genes contain at least one cis stress-response element. Differential expression analysis of 10 samples of RNA-seq data, reviewed RoWRKY genes from black raspberry, show preferential or specific expression in tissue samples. These findings provide a complete overview of the evolution and modification of the RoWRKYs protein family, which will help the functional characterization of these proteins in the response to biotic and abiotic stresses of black raspberry.
