Summary: A disorder named Fatal Yellowing (FY) disease, of unknown etiology, is hindering the growth of the palm oil industry in Brazil. Recent research suggests that oxygen deficiency (hypoxia) damaging the root system may be a potential stressor causing this disease. A comprehensive analysis of metabolome and transcriptome profiles of oil palm plants in terms of FY symptomatology reveals the potential role of hypoxia and provides insights into the genetic expression related to disease onset.

Summary: A novel umbravirus, PSCYV, was discovered in Paederia scandens plants showing leaf chlorosis and yellowing symptoms through RNA-seq. The genome of PSCYV contains four open reading frames encoding different proteins, some of which are involved in symptom development. Furthermore, a cDNA infectious clone of PSCYV was successfully constructed and used to prove its infectivity on different plant hosts.

Summary: There are still knowledge gaps in how to increase biodiversity and ecosystem functioning in cash crop-dominated tropical landscapes in the United Nations Decade on Ecosystem Restoration. This study presents findings from a 5-year ecosystem restoration experiment in an oil palm landscape enriched with 52 tree islands, showing higher indicators of biodiversity and ecosystem functioning in tree islands compared to conventionally managed oil palm. Enriching oil palm-dominated landscapes with tree islands is a promising ecological restoration strategy that does not decrease oil palm yield.

Summary: This study examined the root and shoot morphological traits of three oil palm genotypes with different resistance levels to the fatal yellowing (FY) anomaly. The Interspecific Hybrid demonstrated superior root traits compared to Caiaue and Tenera, which aligns with their varying resistance to FY. These results emphasize the importance of studying the relationship between root morphology and resistance to FY in different genetic materials.

Summary: Agricultural expansion is a major cause of biodiversity decline in tropical forest regions, making it important to understand the conservation value of remnant forests in production landscapes. Research in a tropical landscape dominated by oil palm found that buffer width along rivers is a key factor influencing species richness and abundance, with wider buffers needed to safeguard most species. Increasing relatively narrow buffers can lead to the largest biodiversity gains, highlighting the need for tailored conservation efforts in tropical production landscapes.

Summary: This full factorial experiment conducted in an Indonesian state-owned industrial oil palm plantation evaluated the effects of reduced management practices on ecosystem functions and biodiversity. The results showed that mechanical weeding exhibited higher multifunctionality and increased plant species diversity compared to herbicide treatment. Furthermore, reduced fertilization and mechanical weeding increased profit and gross margin while achieving similar yields.

Summary: This research developed a prototype for fully utilizing palm empty fruit brunches (EFB) to produce sugars and biofuels. The EFB was pretreated with oleaginous fungus and post-treated with mild acid to remove lignin and fractionate hemicellulose from cellulose pulp. The cellulose pulp was used for ethanol production, and repeated-prehydrolysis was attempted to increase sugar concentration. The study also showed the potential use of fungal pretreatment and hemicellulose hydrolysate for lipid accumulation and lactic acid fermentation, respectively. The research provides a practical biorefinery roadmap for bio-valorizing palm biomass wastes into multiple bioproducts, contributing to the Bio-Circular-Green (BCG) economy.

Summary: Farm households in tropical regions are rapidly adopting oil palm, which negatively impacts rainforests and traditional food crops. This study examines the relationship between oil palm adoption, food security, and dietary diversity in Cameroon and Indonesia. The findings show that oil palm farmers in Cameroon have less diverse food consumption, while in Indonesia, oil palm farmers have better dietary diversity. No statistically significant relationship is found between oil palm production and food security, suggesting that income, employment, and farm production diversity may play a role.

Summary: Metagenomic studies have shown the prevalence of Acidobacteria in soils, with many exhibiting carotenoid-related pigments that aid in environmental stress tolerance. Strain AB23 from Acidobacteria produces carotenoids in the presence of light and vitamins, providing tolerance to oxidative stress. The presence of carotenoid genes is widespread among Acidobacteria and provides a competitive advantage in soils with environmental oxidative stress.

Summary: Microbial communities in natural environments are capable of completely deconstructing lignocellulose through synergistic action of enzymes and proteins. While fungi have been extensively studied for lignin degradation, bacteria have also been shown to play a central role in recycling lignin. Direct analysis of environmental samples using metagenomics, metatranscriptomics, and metaproteomics approaches is a powerful strategy for discovering enzymes, metabolic pathways, and microorganisms involved in lignin breakdown.

Summary: Paenibacillus elgii AC13 produces antimicrobial lipopeptides, including cyclic and linear pelgipeptins. The cyclic forms exhibit high stability and antimicrobial activity, while the linear isoforms have lower cytotoxicity. The co-existence of both forms presents a potential advantage in terms of antimicrobial activity and cytotoxic effects.

Summary: Natural selection was used to enrich microbial consortia capable of utilizing lignin as the sole carbon source, resulting in a decrease in bacterial richness and diversity after the enrichment protocol. The type of lignin used as a carbon source had a greater impact on differentiating the bacterial consortia than the variable temperature. Selected bacterial genera for lignin utilization included Altererythrobacter, Bacillus, Pseudomonas, and others.

Summary: Trindade Island, the most recent volcanic component of Brazilian territory, has experienced severe damage to its native vegetation due to human influence. However, after the eradication of goats and other feral animals, the island's vegetation has been recovering, and even rediscovery of endemic species previously considered extinct has been made. Using high throughput sequencing, this study reveals a rich and complex diversity of microorganisms, invertebrates, and plants in the recovering native forest of Trindade Island.
