Transcriptomic Analysis Provides Insights into the Differential Effects of Aluminum on Peanut (Arachis hypogaea L.).

ABSTRACT: In acidic soils, high concentrations of aluminum ions (Al³⁺) in dissolved form reduce root growth and development of most crops. In addition, Al³⁺ is also a beneficial element in some plant species in low concentrations. However, the regulatory mechanism of the growth and development of peanut (Arachis hypogaea L.) treated with different concentrations of Al³⁺ has been rarely studied. In this study, peanut seedlings were treated with AlCl₃.18H₂O in Hoagland nutrient solution at four different concentrations of Al^3+, i.e., 0 (pH 6.85), 1.25 (pH 4.03), 2.5 (pH 3.85), and 5 (pH 3.69) mmol/L, which are regarded as Al0, Al1, Al2, and Al3. The results showed that low concentrations of Al treatment (Al1) promoted peanut grow
