Open AccessA clade of receptor-like cytoplasmic kinases and 14-3-3 proteins coordinate inositol hexaphosphate accumulation
Inositol hexaphosphate (InsP6) is the major storage form of phosphorus in seeds. Reducing seed InsP6 content is a breeding objective in agriculture, as InsP6 negatively impacts animal nutrition and the environmen...

Open AccessThe LRR receptor-like kinase ALR1 is a plant aluminum ion sensor
Plant survival requires an ability to adapt to differing concentrations of nutrient and toxic soil ions, yet ion sensors and associated signaling pathways are mostly unknown. Aluminum (Al) ions are highly phyt...

Structures and mechanisms of the Arabidopsis cytokinin transporter AZG1
Cytokinins are essential for plant growth and development, and their tissue distributions are regulated by transmembrane transport. Recent studies have revealed that members of the ‘Aza-Guanine Resistant’ (AZG...

Structures and mechanisms of the Arabidopsis auxin transporter PIN3
The PIN-FORMED (PIN) protein family of auxin transporters mediates polar auxin transport and has crucial roles in plant growth and development1,2. Here we present cryo-electron microscopy structures of PIN3 from

Open AccessPhloem iron remodels root development in response to ammonium as the major nitrogen source
Plants use nitrate and ammonium as major nitrogen (N) sources, each affecting root development through different mechanisms. However, the exact signaling pathways involved in root development are poorly unders...

Structural basis of ALMT1-mediated aluminum resistance in Arabidopsis
The plant aluminum (Al)-activated malate transporter ALMT1 mediates the efflux of malate to chelate the Al in acidic soils and underlies the plant Al resistance. Here we present cryo-electron microscopy (cryo-...

Open AccessGenome-wide identification and expression analysis of the NAC transcription factor family in tomato (Solanum lycopersicum) during aluminum stress
The family of NAC proteins (NAM, ATAF1/2, and CUC2) represent a class of large plant-specific transcription factors. However, identification and functional surveys of NAC genes of tomato (Solanum lycopersicum) re...

Mechanisms and regulation of aluminum-induced secretion of organic acid anions from plant roots
Aluminum (Al) is the most abundant metal element in the earth’s crust. On acid soils, at pH 5.5 or lower, part of insoluble Al-containing minerals become solubilized into soil solution, with resultant highly t...

FeSTAR2 interacted by FeSTAR1 alters its subcellular location and regulates Al tolerance in buckwheat
Buckwheat (Fagopyrum esculentum) exhibits high Al tolerance, but only a few genes have been functionally characterized. We previously characterized a half-type ABC transporter, Fagopyrum esculentum sensitive to A...

Open AccessXyloglucan Fucosylation Modulates Arabidopsis Cell Wall Hemicellulose Aluminium binding Capacity
Although xyloglucan (XyG) is reported to bind Aluminium (Al), the influence of XyG fucosylation on the cell wall Al binding capacity and plant Al stress responses is unclear. We show that Arabidopsis T-DNA insert...

Open AccessOsTCTP, encoding a translationally controlled tumor protein, plays an important role in mercury tolerance in rice
Mercury (Hg) is not only a threat to public health but also a growth risk factor to plants, as it is readily accumulated by higher plants. Accumulation of Hg in plants disrupts many cellular-level functions an...

Cell wall polysaccharides are involved in P-deficiency-induced Cd exclusion in Arabidopsis thaliana
The physiological and molecular mechanisms leading to the competitive interactions between phosphorus (P) and metal elements are a matter of debate. In this study, we found that P deficiency can alleviate cadm...

Aluminum regulates oxalate secretion and plasma membrane H+-ATPase activity independently in tomato roots
We demonstrated that aluminum (Al)-induced oxalate secretion and plasma membrane (PM) H+-ATPase activity in tomato (Lycopersicon esculentum ‘Hezuo903’) roots were poorly correlated. In addition, vanadate, an inhi...

A Comparison of Aluminum Resistance among Polygonum Species Originating on Strongly Acidic and Neutral Soils
Two kinds of Polygonum species (Polygonum aviculare L. and Polygonum lapathifolium L.) grown in tea garden soils at pH around 3.5 and one Polygonum bungeanum Turcz grown in neutral soils were collected to investi...

A copper-deficiency-induced root reductase is different from the iron-deficiency-induced one in red clover (Trifolium pratense L.)
There is increasing evidence that Cu deficiency can induce root reductase activity, but the ecological and physiological significance of this is unknown. This study compared the characteristics of root reducta...

The kinetics of aluminum adsorption and desorption by root cell walls of an aluminum resistant wheat (Triticum aestivum L.) cultivar
In the present study, root cell walls were extracted from an Al-resistant wheat (Triticum aestivum L.) cultivar, Atlas 66 to investigate the effect of cell-wall properties on the kinetics of Al adsorption and des...

Detoxifying aluminium with buckwheat
Aluminium toxicity is a major problem limiting crop production in acid soils, which account for around 40% of the world's arable land1. Some plants have developed strategies to avoid or tolerate aluminium, includ...

A rapid hydroponic screening for aluminium tolerance in barley
Selection and breeding of crops for aluminium (Al) tolerance is a useful approach to increase production on acid soils. This requires a rapid and reliable system to discriminate between Al-tolerant and Al-sens...
