Aluminium (Al) toxicity is one of the most important limiting factors for crop yield in acidic soils. However, the mechanisms that confer Al tolerance remain largely unknown. Based on the global transcriptome analysis of the roots and leaves of two contrasting soybean genotypes, BX10 (Al-tolerant) and BD2 (Al-sensitive) under 0 µM and 50 µM Al3+ treatments, our findings suggest that BX10 can resist Al by secreting additional citrate into the rhizosphere from the roots to chelate Al and by avoiding a JA-mediated defense response that allows resource allocation to maintain leaf growth.
