Summary: The study compared the effects of selective harvesting and one-time total harvesting, and found that it was not possible to only harvest ripe fruits regardless of the management zone. The tested harvester settings did not change the amount of fruits harvested, and higher operational speed was recommended for economic reasons.

Summary: This study evaluated the effects of two agroforestry systems (AFS-G: coffee intercropped with Grevillea robusta, AFS-C: coffee intercropped with Toona ciliata) and Coffea arabica monoculture on soil microbial biomass and activity in a tropical high-altitude climate region in Brazil. The AFS-G system maintained similar levels of microbial activity and enzyme activities compared to the native forest, while the AFS-C system had higher microbial biomass carbon. Coffee agroforestry systems in this region are more favorable for maintaining microorganisms and their activity in the soil, supporting their sustainable management for coffee growing.

Summary: NMR was used to identify metabolic changes in green coffee beans stored in different packages. The sensory quality of beverages deteriorated more in paper bags after 6 months of storage, while high barrier bags and vacuum packs maintained quality for 18 months. NMR allowed the differentiation of coffee packed in paper bags from the 3rd month of storage, providing an early identification of changes that would otherwise only be noticed through sensory analysis after six months. Choline and glycerophosphocholine were the main compounds associated with the observed changes in coffee stored in paper bags.

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: In this study, ten new and five known ent-kaurane diterpene derivatives were identified from roasted coffee beans. Several compounds showed moderate inhibitory effects on alpha-glucosidase, with those containing a double bond between C-15 and C-16 exhibiting stronger activity. Molecular docking experiments were also conducted to discuss the mechanism of action.

Summary: The aim of this study was to characterize Meloidogyne paranaensis populations collected from infested coffee crops. The characterization involved morphological analysis, biochemical analysis, sequencing of DNA regions, reproductive fitness, and virulence characterization in coffee genotypes. The results showed variation between populations in morphology, biochemical profiles, and virulence. Resistance genes in coffee genotypes were found to affect the virulence of the populations.

Summary: This paper investigates how landscape structure can influence coffee production at different scales, and evaluates the predictive utility of landscape metrics. The study finds that the composition of the landscape surrounding coffee farms helps predict production in a spatially explicit approach, but these metrics cannot detect the impact of the landscape in an aspatial approach. The findings highlight the importance of landscape spatial structure in the stability of coffee production.

Summary: The study screened 672 candidate SNPs using Nano-Fluidic Array genotyping and selected a panel of 96 SNPs for genotyping Coffea arabica based on call rate, Minor Allele Frequency, and Linkage Disequilibrium. This validated panel is suitable for coffee germplasm conservation, crop improvement, varietal identification, seed and nursery accreditation, and coffee bean authentication.

Summary: This study evaluated the responses of arabica coffee genotypes in the Brazilian Cerrado region to different levels and durations of water deficit. The results showed that plants under full irrigation conditions had higher gas exchange and relative water content, while rainfed and water deficit treatments led to reduced physiological and productive potential.

Summary: This paper investigates the role of cytokinins in Coffea canephora and uncovers a cross-talk between cytokinins and auxin, where auxin represses cytokinin biosynthesis and degradation while cytokinins induce genes involved in their homeostasis.

Summary: The study analyzed the genetic distances between parental clones of Robusta coffee hybrids and found a significant correlation between genetic distances and hybrid yield performance. Selecting hybrids with higher genetic distances can increase yield gain, and inter-group hybrids outperformed intra-group hybrids in cumulative yield.

Summary: Robusta coffee is an important source of income and employment for many developing countries. However, genetic erosion from the introduction of Congolese accessions threatens the genetic integrity of wild populations from the Guinean gene pool. Pollen from the Congolese gene pool shows greater ability to pollinate the Guinean group, necessitating conservation measures for wild populations.

Summary: This study demonstrates that exogenous MeJA application can enhance ROS scavenging in tea plants under cold stress, while also identifying three CsMYB genes as key components in the cold-stress signal response pathway. Further experiments reveal that CsMYB45, CsMYB46, and CsMYB105 may serve as points of confluence for cold stress and JA signaling pathways. These findings provide new insights into how MYB TFs influence cold tolerance in tea and offer candidate genes for future functional studies and breeding.

Summary: Cacao is an important tropical crop, but the soils it grows in are often acidic and low in fertility. This study evaluated 60 cacao genotypes and found that early growth predictors of acid soil tolerance are the number of leaves and root area. Nutrient uptake, particularly for N, Ca, Mg, and K, may play a role in soil acidity tolerance. Ten genotypes were identified as potentially tolerant to soil acidity and could be used for breeding acid soil-tolerant cacao varieties.

Summary: This study focuses on the genetic structuring of Coffea canephora populations in Côte d'Ivoire using SNP markers. The results reveal the presence of two main genetic groups, Guinean and Congolese, and four subgroups within the Congolese group. Among the agronomic traits analyzed, the SG1 and SG2 subgroups displayed the highest performance. The findings highlight the importance of selecting the best progenitors within the Guinean group. This research provides valuable insights for future coffee breeding programs.

Summary: The research on the growing patterns of 'Lingwu Changzao' jujube shows that fruit traits follow double 'S' growth curves, while stone traits stop increasing early in fruit growth period. This indicates a high fruit-stone ratio as a desirable quality attribute for 'Lingwu Changzao' as fresh-eating fruits.
