Integrating DynamiCROP model and risk assessment for pesticide residues in spinach: Implications for food safety

Pest Management Science, Volume 82, Issue 7, Page 7154-7163, July 2026.
This study adapted and validated the dynamiCROP model for spinach, a leafy vegetable not previously included in its standard framework. The findings confirm that model‐predicted pesticide concentrations, when integrated into hazard quotient (HQ) calculations, can effectively support dietary risk assessment.

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2087-2104, July 2026.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.
