Abstract

ABSTRACT Phosphorus (P) is an essential element for crop production; however, availability tends to be low due to slow diffusion and high fixation in soils. To cope with phosphate deficiency, white lupines (Lupinus albus L.) form unique root structures called cluster roots. The objective of this study was to elucidate detailed spatial differences of the mechanisms under low-P condition in the root system using rhizoboxes. We cultivated plants in rhizoboxes with P-deficient soil for 33 days. We then harvested roots and the adjacent soil from 128 compartments by dividing 2 × 2 cm squares in the rhizoboxes. We investigated relative expression levels of several genes that encode proteins assumed to be involved in P solubilization or translocation. Additionally, we analyzed fractionated P, soluble metal cations (Fe, Al, and Mn), and enzyme activities in the soil of each compartment. We observed a significant positive correlation between one of the MATE (multidrug and toxic compound extrusion/detoxification) genes, LaMATE6, and soluble metal cations, suggesting the secretion of citric acid into the rhizosphere via MATE proteins increased soluble metal cation concentrations. Furthermore, we demonstrated that roots in the same developmental stages were likely to have different influences on the mobilization of fractionated P in the rhizosphere soil. Our findings highlight the importance of investigating the relationship between soil chemical properties and root functions at a high spatial resolution to elucidate the detailed mechanisms of P mobilization by plants.

白羽扇豆特定根部土壤磷动态与低磷响应的关系
磷(P)是作物生产的必需元素;然而,由于土壤的扩散缓慢和高度固定,有效度往往较低。为了应对磷酸盐缺乏,白色羽豆(Lupinus albus L.)形成独特的根结构,称为簇根。本研究的目的是利用根箱详细阐明低磷条件下根系代谢机制的空间差异。在缺磷土壤根箱中栽培植株33天。然后,我们通过在根箱中划分2 × 2厘米的正方形,从128个隔间中收获根和邻近的土壤。我们研究了几个基因的相对表达水平,这些基因编码的蛋白质被认为参与磷的溶解或易位。此外,我们还分析了每个隔室土壤中的分离磷、可溶性金属阳离子(铁、铝和锰)和酶活性。我们观察到MATE(多药和有毒化合物挤出/解毒)基因之一LaMATE6与可溶性金属阳离子之间存在显著的正相关,这表明柠檬酸通过MATE蛋白分泌到根际增加了可溶性金属阳离子的浓度。此外,我们还证明了处于相同发育阶段的根系对根际土壤中分馏磷的动员可能有不同的影响。我们的研究结果强调了在高空间分辨率下研究土壤化学性质与根系功能之间的关系对于阐明植物动员磷的详细机制的重要性。
