Abstract:
Fatal Yellowing (FY) is a severe disorder that compromises oil palm (Elaeis guineensis) production in tropical regions of Latin America. Despite extensive research, its etiology remains unclear. This study aimed to investigate environmental and physiological factors associated with FY development under Amazonian conditions. We integrated field epidemiological data with soil classification and fertility, plant nutrient composition, climatic parameters, and proteomic profiles of symptomatic and asymptomatic palms. The results revealed a consistent association between abiotic stresses such as waterlogging, soil type, nutrient imbalance and the occurrence of FY. Proteomic analysis indicated metabolic adjustments linked to stress tolerance and defense responses. Our findings reinforce the hypothesis that environmental constraints play a decisive role in FY onset and progression, contributing to improved understanding and management strategies for sustainable oil palm cultivation in tropical regions.
