This study shows that the MADS-WUS axis regulates floral initiation rates in barley, influencing inflorescence architecture and reproductive strategies through allele selection and duplication.

This study identifies a hypermorphic mutation in TaARF4-A2 that represses SPL-mediated developmental timing, leading to altered wheat architecture by promoting aerial branching and reducing reproductive development.

This study shows that the fungal endophyte Macrophomina phaseolina interacts with the coumarin scopoletin to enhance Arabidopsis iron nutrition by converting it into iron-chelating esculetin.

This study shows that knocking out OsVIT1 and OsVIT2 in rice increases seed iron content but reduces iron excess tolerance, revealing a trade-off between biofortification and toxicity resistance.
