Comparison of the profile of gene expression in nodal tissues of osvoz1, osvoz2 and their WT plants
Rice is the major source of arsenic (As) intake in humans, as this staple crop readily accumulates As in the grain. Identifying the genes and molecular mechanisms underlying As accumulation and tolerance is a crucial step towards developing rice with reduced As levels. We identified zinc finger-type transcription factors OsVOZ1 and OsVOZ2 conferring As tolerance. The double knockdown of OsVOZ1 and OsVOZ2 reduced As accumulation in their seeds. These findings suggest that rice VOZs regulate the translocation of As into grins. Here, we compared the profile of gene expression in nodal tissues of osvoz1 and osvoz2 knockout and their WT plants, to understand how OsVOZs regulate As accumulation in grains.
