“…The genus Rubus consisted of several hundred species, and the ploidy level can widely vary among them. Raspberries are mainly diploids (2n = 14), while blackberries may vary from diploids to dodecaploids (2n = 84), whereas the hybrids between them can be hexaploid (loganberry) or septaploid (boysenberry) [7]. A total of 22 wild species of Fragaria have been described.…”

Strawberry (Fragaria) and raspberry (Rubus) are very popular crops, and improving their nutritional quality and disease resistance are important tasks in their breeding programs that are becoming increasingly based on use of functional DNA markers. We identified 118 microsatellite (simple sequence repeat-SSR) loci in the nucleotide sequences of flavonoid biosynthesis and pathogenesis-related genes and developed 24 SSR markers representing some of these structural and regulatory genes. These markers were used to assess the genetic diversity of 48 Fragaria and Rubus specimens, including wild species and rare cultivars, which differ in berry color, ploidy, and origin. We have demonstrated that a high proportion of the developed markers are transferable within and between Fragaria and Rubus genera and are polymorphic. Transferability and polymorphism of the SSR markers depended on location of their polymerase chain reaction (PCR) primer annealing sites and microsatellite loci in genes, respectively. High polymorphism of the SSR markers in regulatory flavonoid biosynthesis genes suggests their allelic variability that can be potentially associated with differences in flavonoid accumulation and composition. This set of SSR markers may be a useful molecular tool in strawberry and raspberry breeding programs for improvement anthocyanin related traits.

“…Strawberries are native to the North and South of America; however, the breeding of plants to obtain fruits with better sensory characteristics, higher productivity, and longer post-harvest life was mainly undertaken in France, the Netherlands, and England and later returned to North America, where their improvement continued (Darrow, 1966). China is considered to have the greatest diversity of raspberries and blackberries (Swanson et al, 2011), and blueberries are native to North America (González de Mejía and Johnson, 2015).…”

This paper examines the configuration of the global value chain of berries (GVCB) by analysing the trajectories and strategies of global trading firms; as well as the local advantages of Chile and Mexico that allowed them to integrate into this chain. The study applies the basis of the methodology of multiple case studies. The results show that the trading companies configured the GVCB by making use of their knowledge of the berry market, the plant genetic improvement, the growth in the world consumption, and the advances in the logistics for long-distance trading. Trading companies promoted the berry production of Chile and Mexico to reduce the seasonality of the offer considering their comparative advantages, such as access to destination markets, the agro-climatic conditions, the availability and cost of production factors, and the institutional context. Multinational berry traders have driven the configuration of GVCB through global expansion strategies and use their governance power to coordinate global chain operations. Local actors from both countries took the opportunity to integrate into global markets and developed highly dynamic production clusters, which they adapted to their conditions. The GVCB also faces challenges due to growing concerns about environmental care and social responsibility for workers.

“…Raspberries exhibit cold and drought resistance but are sensitive to high temperatures, making HS a significant limiting factor affecting raspberry production and cultivation ( Swanson et al., 2011 ). Under HTS, plants undergo morphological changes and physiological and biochemical responses, including photosynthesis, respiration, cell membrane stability, sugar, lipid, and amino acid metabolism, as well as the expression of resistance genes and proteins.…”

With global climate warming, recurring extreme heat and high temperatures irreversibly damage plants. Raspberries, known for their nutritional and medicinal value, are in high demand worldwide. Thus, it is important to study how high-temperature stress (HTS) affects raspberries. The physiological and biochemical responses and molecular genetic mechanisms of raspberry leaves to different HTS treatments were investigated: mild high temperature at 35°C (HT35), severe high temperature at 40°C (HT40), and the control at room temperature of 25°C (CK). The physiological results suggested that leaves in both the 35°C and 40°C treatments showed maximum relative conductivity at 4 d of stress, increasing by 28.54% and 43.36%, respectively, compared to CK. Throughout the stress period (0–4 d), malondialdehyde (MDA) and soluble protein contents of raspberry leaves increased under HT35 and HT40 treatments, while soluble sugar content first decreased and then increased. Catalase (CAT) activity increased, superoxide dismutase (SOD) activity first increased and then decreased, and peroxidase (POD) activity gradually decreased. Photosynthetic and fluorescence responses of raspberry leaves showed the most severe impairment after 4 d of stress. Transcriptomics results revealed significant alterations in 42 HSP family genes, two SOD-related differentially expressed genes (DEGs), 25 POD-related DEGs, three CAT-related DEGs, and 38 photosynthesis-related DEGs under HTS. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that these DEGs were mainly enriched in photosynthesis-antenna proteins, pentose and glucuronide interconversion, phenylpropane biosynthesis, and indole alkaloid biosynthesis. HTS induced excessive ROS accumulation in raspberry leaves, causing oxidative damage in plant cells and subsequently reducing photosynthesis in raspberry leaves. This reduction in photosynthesis, in turn, affects photosynthetic carbon fixation and starch and sucrose metabolism, which, combined with phenol propane biosynthesis, mitigates the HTS-induced damage.
