Open AccessGenome-resolved metagenomics reveals role of iron metabolism in drought-induced rhizosphere microbiome dynamics
Recent studies have demonstrated that drought leads to dramatic, highly conserved shifts in the root microbiome. At present, the molecular mechanisms underlying these responses remain largely uncharacterized. ...

Open AccessArabidopsis thaliana zinc accumulation in leaf trichomes is correlated with zinc concentration in leaves
Zinc (Zn) is a key micronutrient for plants and animals, and understanding Zn homeostasis in plants can improve both agriculture and human health. While root Zn transporters in plant model species have been ch...

Genome-wide association map** for grain manganese in rice (Oryza sativa L.) using a multi-experiment approach
Manganese (Mn) is an essential trace element for plants and commonly contributes to human health; however, the understanding of the genes controlling natural variation in Mn in crop plants is limited. Here, th...

Open AccessA heavy metal P-type ATPase OsHMA4 prevents copper accumulation in rice grain
Rice is a major source of calories and mineral nutrients for over half the world’s human population. However, little is known in rice about the genetic basis of variation in accumulation of copper (Cu), an ess...

A review of recent developments in the speciation and location of arsenic and selenium in rice grain
Rice is a staple food yet is a significant dietary source of inorganic arsenic, a class 1, nonthreshold carcinogen. Establishing the location and speciation of arsenic within the edible rice grain is essential...

Activation of rice Yellow Stripe1-Like 16 (OsYSL16) enhances iron efficiency
Graminaceous plants release ferric-chelating phytosiderophores that bind to iron. These ferric-phytosiderophore complexes are transported across the plasma membrane by a protein produced from Yellow Stripe 1 (YS1

Metal Transport
One-third of all proteins require metal cofactors for function, yet metals can be toxic and need to be tightly controlled. Metal homeostasis is basically the equilibrium between metal uptake and metal efflux, ...

OsZIP5 is a plasma membrane zinc transporter in rice
Zinc is essential for normal plant growth and development. To understand its transport in rice, we characterized OsZIP5, which is inducible under Zn deficiency. OsZIP5 complemented the growth defect of a yeast Zn...

Zinc deficiency-inducible OsZIP8 encodes a plasma membrane-localized zinc transporter in rice
Zinc is an essential micronutrient for several physiological and biochemical processes. To investigate its transport in rice, we characterized OsZIP8, a rice ZIP (Zrt, Irt-like Protein) gene that is strongly up-r...
