Here, we character - Key message Plants overessing expr AtHSCB and hscb ized Arabidopsis thaliana plants overexpressing AtHSCB, knockdown mutants showed altered iron homeosta - encoding a mitochondrial cochaperone involved in [Fe–S] sis. The overession of expr AtHSCB led to activation of cluster biosynthesis, and hscb knockdown mutants, which the iron uptake system and iron accumulation in roots exhibit altered shoot/root Fe partitioning. Overexpression of without concomitant transport to shoots, resulting in AtHSCB induced an increase in root iron uptake and con- educed irr on content in the aerial parts of plants.

Conversely, hscb contrast, hscb knockdown mutants presented the oppo - knockdown mutants exhibited increased iron accumulation site phenotype, with iron accumulation in shoots despite in shoots and reduced iron uptake Plant Molecular Biology Springer Journals
