Summary: The study on oil palm seedlings of G and OG genotypes revealed that water deficit led to reductions in leaf relative water content, photosynthetic rate, stomatal conductance, transpiration rate, and water use efficiency. The response of gas exchange and biochemical related variables to water deficit was dual-phased, with stomatal closure being the initial response followed by a reduction in biochemical photosynthetic capacity.

Summary: This study identified potential embryogenic oil palms through leaf transcriptomic analysis and found that genes involved in flowering time and light responses may be associated with somatic embryogenesis potential. The research also showed that machine learning approaches with candidate genes could create a more sensitive model to differentiate between non-embryogenic and embryogenic oil palms.

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: Continuous discovery of novel in vitro plant culture practices is crucial for better plant growth in a shorter period. Using Plant Growth Promoting Rhizobacteria (PGPR) in the biotization process allows for sustained populations and improved tolerance to stresses, reducing mortality rates. Understanding the mechanisms and evaluating biochemical activities are essential for studying in vitro plant-microbe interactions. This review provides an overview of the in vitro oil palm plant-microbe symbiosis system.

Summary: Green renewable biolubricants base stock based on polyol triester of epoxidized Malaysian Elaeis guineensis palm kernel oil and trimethylolpropane was produced and optimized using response surface methodology. The optimal condition for the epoxidation process was achieved, resulting in a high epoxide yield of 92.5% and excellent lubrication properties of EPKO-TMPE. Tribological assessments showed that EPKO-TMPE exhibited low coefficients of friction in the hydrodynamic region and was comparable to marketable lubricants.

Summary: EgMADS16, a MADS-box transcription factor in oil palm, is highly expressed during late fruit development and is predicted to be targeted by EgmiR5179. Experimental results suggest that EgMADS16 expression is downregulated by EgmiR5179, impacting lipid metabolism in oil palm.

Summary: Environmental conditions play a crucial role in the growth and productivity of crops, particularly through the process of photosynthesis using solar radiation. Factors such as leaf area, light interception, and photosynthetic performance affect crop growth and yield. The canopy extinction coefficient and planting density have significant impacts on crop growth and yield.

Summary: The African Oil Palm is a crucial oil crop for food, feed, and biotechnological applications. Research has identified significant amounts of fatty acid phytyl esters and fatty acid geranylgeranyl esters in the mesocarp and kernel tissues of the fruit, providing additional metabolic sources for fatty acids and alcohols. Enzymatic reactions were shown to be involved in the synthesis of these compounds, with potential implications for carotenoids and tocotrienols production.

Summary: A comparative proteomic approach was used to study protein changes in early oil palm fruit development, identifying potential candidates in energy metabolism, stress responses, and cell structure. Transcript and protein profiles were parallel across developmental stages, with some divergent expression observed in specific protein spots. This study provides valuable information on physiological processes during early oil palm fruit development and can contribute to improving fruit quality traits.

Summary: Oil palm is the most productive oil-producing crop and accumulates the highest amount of oil in its fruit. Comparative analysis of high-, medium-, and low-yielding oil palms revealed unique characteristics during fruit development. Metabolomics analysis showed that starch and sucrose can be used as novel biomarkers for oil yield, as there were significant differences in starch parameters and sucrose levels among different yield categories.

Summary: The study revealed that certain metabolites, particularly caffeate, are specifically accumulated in somatic embryos of oil palm. Caffeate was found to have significant correlations with phytohormone signaling genes and somatic embryogenesis transcription factors, suggesting its importance in the mechanism of somatic embryogenesis in oil palm. Furthermore, staining and microscopic observation showed phenolic acids highly accumulate in the center of newly formed callus clusters, indicating their role in somatic embryo development.

Summary: The study focuses on using oil palm frond as a plentiful and inexpensive waste material to produce ethanol through optimized alkaline pretreatment. The research finds that the optimized alkaline extraction conditions can significantly enhance cellulose content and remove lignin. Moreover, simultaneous saccharification and fermentation at 40 degrees Celsius result in the highest ethanol production.

Summary: This paper introduces a non-destructive technique using electrical impedance spectroscopy to predict the moisture and oil content in oil palm fruitlets. By analyzing the variation of electrical impedance values, the moisture and oil content can be predicted effectively. This method can be used for fruit grading and oil yield estimation in the palm oil industry.
