Summary: Species of the genus Coffea accumulate diterpenes in their seed endosperm that have antifungal and anti-insect activities. Cafestol significantly inhibits the growth of phytopathogenic fungi and reduces the development of fruit flies. The diterpenes are stored in esterified form and transferred from the endosperm to other organs during seedling growth.

Summary: The study assessed the dominant sensory attributes and preference for cold brews made with Arabica and Robusta coffees under different brewing conditions. While coffee flavor and bitter taste were dominant sensory attributes, the compositions differed among the cold brews. Arabica cold brews had more sourness and coffee flavor, while Robusta cold brews had more bitterness and astringent sensation.

Summary: Coffee tree microbiome varies among different coffee species, with C. arabica and C. stenophylla having different microbiomes compared to other species. Streptomyces and mycorrhizal fungi dominate the microbial communities in the rhizosphere. Sucrose concentration influences fungal communities, while caffeine/theobromine concentration has little effect. The study also suggests a possible relationship between drought tolerance in coffee trees and growth-promoting microorganisms.

Summary: The study found that roasted coffee extracts have inhibitory effects on Salmonella and E. coli, while not affecting probiotic Lactobacillus plantarum and Lactobacillus rhamnosus. In the food matrix, roasted coffee extracts reduced the multiplication of Salmonella and E. coli, but did not inhibit the growth of probiotics.

Summary: This study evaluated the antimicrobial potential of coffee extracts against Salmonella Typhimurium, Escherichia coli, and probiotics Lactobacillus plantarum and Lactobacillus rhamnosus. The results showed that roasted coffee extracts inhibited the growth of Salmonella Typhimurium and Escherichia coli, while probiotics were unaffected. This suggests that coffee extracts could be used as an antimicrobial agent in the food industry, particularly in probiotic foods.

Summary: Recent studies have found that mitochondrial transfer between cells can impact cellular and tissue homeostasis. While most previous research focused on the transfer of functional mitochondria to cells with damaged networks, this study reveals that dysfunctional mitochondria can also be transferred between cells with functioning networks. The transfer of dysfunctional macrophage mitochondria to cancer cells leads to an accumulation of reactive oxygen species, activating signaling pathways that promote cancer cell proliferation. These findings provide insights into how transferred mitochondria can drive sustained behavioral changes in recipient cells.

Summary: In this study, orchid seeds were found to establish a relationship with orchid mycorrhizal fungi for germination, with Tulasnella calospora (Tca) showing significant seed germination-promoting effects on Cymbidium mannii and Epidendrum radicans. Different concentrations of oatmeal agar (OA) medium influenced the symbiosis and compatibility of the fungi with the orchids, highlighting the importance of mycorrhizal technology for the propagation and conservation of endangered orchid species.

Summary: Recent studies have shown differences in the leaf mycobiome between traditional crop Arabica coffee and wild species Racemosa and Stenophylla. The core leaf mycobiome among the three Coffea species includes fungi like Hannaella and Cladosporium. Additionally, the research also revealed significant variations in caffeine and chlorogenic acid content among C. arabica, C. racemosa, and C. stenophylla.

Summary: This study investigated the impact of Meloidogyne paranaensis on coffee crops in Brazil and the management strategy of using resistant cultivars. Results indicated that an initial population density of 1000 eggs per plant, inoculated in plants with four leaf pairs, could be used for phenotyping coffee genotypes evaluated between 80 and 90 days after inoculation.

Summary: In this study, a NAC25-like transcription factor was isolated and characterized from different coffee species. The gene structure, variation, and expression of the NAC25 gene were analyzed. The study demonstrated differential expression of NAC25 in different tissues and revealed the independent evolution of NAC25 in coffee.

Summary: This study evaluates the impact of environmental, agronomic, and post-harvest processing factors on the cup quality and physicochemical characteristics of Robusta and Arabica coffee. While Arabica coffee is predominantly studied for its aroma and unique flavor profile due to its high market share, Robusta coffee attracts attention for its increasing industrial value and drought resistance.

Summary: This study reveals that polycyclic aromatic hydrocarbons can impact the growth and physiology of potentially toxic diatoms, with P. mannii showing higher tolerance and faster growth compared to P. hasleana. Both species were also capable of bioconcentrating and degrading PAHs, with P. mannii harboring more efficient hydrocarbon-degrading bacteria.Further research should explore the bacterial community associated with Pseudo-nitzschia species for a better understanding of their responses to pollutants and other environmental stressors.

Summary: This study assembled the first leaf transcriptome of Coffea liberica, generating 55,446 transcripts with about 70% of them annotated in public databases. Phylogenetic analysis revealed the close relationship between Coffea liberica and Coffea canephora. The study also highlighted the important role of PAL genes in coffee growth and defense regulation.
