Aluminum (Al) toxicity in acidic soils is a major constraint on global crop production. In contrast, native species of the Brazilian Savanna (Cerrado), such as Qualea dichotoma Mart. & Warm. (Vochysiaceae), have not only adapted to these conditions but exhibit an Al requirement for growth. This species efficiently accumulates Al, even in soils with low Al availability. Despite the significance of Al metabolism in plants, native Al-accumulating species like Q. dichotoma remain understudied, particularly at the molecular level. This study presents the first proteomic analysis of Q. dichotoma leaves from Al-supplemented and non-supplemented plants using label-free mass spectrometry. Our dataset comprises 1,255 proteins identified by querying the Uniprot Myrtales database and 1,062 proteins against the Q. grandiflora genome database. respectively. These findings provide a foundational resource for understanding the role of Al in native plant metabolism and advance our knowledge of plant-metal interactions. The raw data are publicly available via the Centre for Computational Mass Spectrometry (MassIVE ID: MSV000092667). https://massive.ucsd.edu/ProteoSAFe/dataset.jsp?task=7ae50a0d01d942c78da2caec254093f0.
