A study discovered an oil crop that can tolerate and accumulate harmful heavy metal cadmium, with altered constituents and increased antioxidant enzyme activity. Transcriptome analysis revealed genes related to Cd stress and tolerance mechanisms, making it a potential Cd accumulator with valuable insights into its tolerance mechanisms.
Researchers created hybrid plants by crossing different genotypes of three Brassica species. These hybrids showed low fertility and mostly sterile self-pollinated progeny. Retaining both subgenomes was found to be important for fertility, emphasizing the significance of subgenome relationships in hybridization outcomes.
Scientists are working on genetically modifying oilseed mustard to improve its yield and resistance to insects and herbicides. They are using CRISPR-Cas9 tools to introduce new traits, but face challenges in the transformation process. This study provides an overview of the progress and potential solutions, which may improve oilseed mustard crop plants.
