How carbon (sucrose) and nitrogen (amino acid) accumulation is coordinatively controlled in cereal grains remains largely enigmatic. We found that overexpression of the strigolactone (SL) biosynthesis gene CAROTENOID CLEAVAGE DIOXYGENASE 8 (CCD8) resulted in greater ear diameter and enhanced sucrose and amino acid accumulation in maize kernels. Loss of ZmCCD8 function reduced kernel growth with lower sugar and amino acid concentrations.

- Strigolactones are phytohormones that significantly affect the germination and growth of arbuscular mycorrhizal fungi (AMF), with previous studies focusing on individual strains.
- In experiments with AMF strains A5 and C2, C2 showed high germination rates regardless of conditions, while A5's germination improved with strigolactones but decreased in mixed cultures.
- The study indicates that strigolactones can influence competitive relationships among AMF strains, with unique responses suggesting potential shifts in community dynamics.
Article Synopsis
- The study explores the development of a generic physiologically based kinetic (PBK) model for assessing the effects of organophosphate (OP) pesticides on both rats and humans.
- It utilizes data from existing studies and quantitative structure property relationships to evaluate how well the model predicts the absorption and toxicity of various OP compounds, showing high accuracy in most cases.
- The findings suggest this PBK model can be a valuable tool for next generation risk assessment (NGRA) of OP pesticides and potentially be adapted for other chemical classes.
Phosphate (P) plays a key role in plant growth and development. Hence, plants display a range of adaptations to acquire it, including changes in root system architecture (RSA). Whether P triggers directional root growth is unknown.
