Cadmium (Cd) toxicity severely limits plant growth and development. Moreover, Cd accumulation in vegetables, fruits, and food crops poses health risks to animals and humans. Although the root cell wall has been implicated in Cd stress in plants, whether Cd binding by cell wall polysaccharides contributes to tolerance remains controversial, and the mechanism underlying transcriptional regulation of cell wall polysaccharide biosynthesis in response to Cd stress is unknown.

Deoxyribonucleic acid (DNA) methylation is an important epigenetic mark involved in diverse biological processes. Here, we report the critical function of tomato () () in plant growth and development, especially in leaf interveinal chlorosis and senescence. Using a hairpin RNA-mediated RNA interference (RNAi), we generated -RNAi lines and observed pleiotropic developmental defects including small and interveinal chlorosis leaves.

Article Synopsis
  • Researchers explored how epigenetics affects iron (Fe) homeostasis in plants, focusing on a mutant variety showing heightened Fe-deficiency responses compared to the wild type.
  • RNA sequencing identified significant changes in gene expression related to Fe deficiency, highlighting impacts on enzymes, transporters, and transcription factors.
  • The study revealed key genes potentially regulated by epimutation and demonstrated that specific gene knockouts exhibited similar Fe-deficiency responses, indicating a novel regulatory role for the epimutant in tomato plants.
