Summary: In this study, CRISPR/Cas9 system was established in Hevea brasiliensis using five endogenous U6 promoters to drive sgRNA transcription. Mutation patterns were characterized in protoplasts targeting flowering time related genes, and insertion, deletion, and base substitution mutations were detected. A stable transformation editing vector targeting the phytoene desaturase gene was constructed and induced albino phenotype in rubber tree callus. This study demonstrates successful establishment of genome editing in Hevea brasiliensis using CRISPR/Cas9 plasmid system.

Summary: The study found that compared to the primary rainforest, the land quality index of monocultural rubber cultivation decreased by 15.50%, with significant soil nutrient loss (18.90%). However, rubber-based agroforestry practices significantly enhanced the soil quality index (25.30% for rubber-tea agroforestry and 33.10% for rubber-Dracaena agroforestry) compared to monoculture, suggesting that polyculture practices are suitable for soil quality recovery in degraded agricultural lands. Chemical parameters played a greater role in contributing to the soil quality index than physical parameters, indicating the importance of nutrient management in soil quality recovery.

Summary: This study investigates the potential impact of fermentation on coffee quality by applying different fermentation processes to Coffea canephora var. conilon. Sensory analysis and chemical profiling were used to examine the quality and chemical composition of roasted coffees. The results identified several compounds, including chlorogenic acids, caffeine, gamma-butyrolactone, lipids, sugars, and acetic acid, as important factors influencing the different fermentation processes and the sensory quality of the coffee. Lipids were found to be a significant marker for coffee quality.

Summary: This study identified and characterized lncRNAs in Hevea brasiliensis by integrating transcriptome datasets from multiple tissues. The results showed that rubber lncRNAs have distinctive features such as longer exon, lower expression levels and GC content, and more tissue specificity compared to mRNAs. Thousands of tissue-specific lncRNAs were discovered in rubber tissues, and the functional enrichment analysis indicated their potential roles in tissue-specific functions.

Summary: This study evaluated the physicochemical, thermal, and structural properties of latex and dry rubber from four rubber tree clones, and assessed the relationship to the final properties of natural rubber (NR). Variations in chemical composition were observed among clones and tapping periods, while thermal and structural evaluations showed uniformity across all clones. Comparison among clones, extraction periods, and within the same clone allowed for analysis of performance and uniformity of the rubber produced.

Summary: This study found that cold treatment induces global genomic DNA demethylation and alters the sequence contexts of methylated cytosines in Hevea brasiliensis. DNA demethylation in the upstream region of genes correlates with higher gene expression, whereas demethylation in the gene body has less association.

Summary: This study aims to validate the identified variants of Familiar Renal Glucosuria (FRG) according to the ACMG-AMP 2015 criteria. The variants evaluated include 16 novel alleles, all of which are rare or absent from population databases and mostly missense changes. According to the ACMG-AMP standards, only 74% of the variants were classified as likely pathogenic or pathogenic. The lack of related patient descriptions and testing of additional affected family members prevented conclusive determination of pathogenicity for variants classified as variants of unknown significance (VUS), highlighting the importance of family testing and variant reporting. Finally, the cryo-EM structure analysis improved the pathogenicity score by identifying critical/functional protein domains.

Summary: This study analyzed the transcriptome changes in coffee plants under different water availability and elevated CO2 levels. Severe water deficits led to down-regulation of most differentially expressed genes, while elevated CO2 mitigated the impacts of drought. The response of coffee plants to water stress is mainly associated with reactive oxygen species scavenging and ABA signaling pathways.

Summary: The selection of suitable plants for contaminated/degraded mining areas is crucial for environmental management. This study investigated the use of a fast-growing forestry species, Eucalyptus nitens, for the recovery of arsenic (As) from artificially contaminated soils. The results showed that Eucalyptus nitens can accumulate high levels of As in its roots without apparent damage, making it a potential candidate for phytoremediation in cool climate areas.

Summary: Climate change has negative impacts on the global coffee industry, affecting around 100 million people from 80 countries. This is mainly due to the vulnerability of mainstream coffee species to extreme weather events, resulting in uneven increases in market prices. Wild-relatives and underutilized coffee species are valuable genetic resources for introducing more resilient species and increasing genomic diversity in climate-smart practices.

Summary: Coffee, the second most consumed beverage in the world, plays a vital role in the global economy. However, studies have shown that climate change-induced increase in UV radiation can significantly impact coffee crops. UV radiation can negatively affect the morphology, anatomy, physiology, and biochemistry of coffee plants, leading to growth and yield limitations. On the other hand, plants can respond positively to UV radiation through increased environmental resistance and growth promotion.
