The endophytic fungus Serendipita indica alters auxin distribution in Arabidopsis thaliana roots through alteration of auxin transport and conjugation to promote plant growth

This study identifies how the endophytic fungus Serendipita indica promotes Arabidopsis growth by altering auxin transport and conjugation through GH3 genes and PIN2 expression.

The trans-zeatin-type side-chain modification of cytokinins controls rice growth

This study identifies CYP735A3 and CYP735A4 as enzymes required for tZ-type cytokinin biosynthesis in rice, showing their role in growth promotion of both roots and shoots.

Photosynthetic-product-dependent Activation of Plasma Membrane H+-ATPase and Nitrate Uptake in Arabidopsis Leaves.

This study shows photosynthesis-dependent activation of PM H+-ATPase in Arabidopsis leaves enhances nitrate uptake, linking photosynthesis and nitrogen metabolism.

Isolation of gametes and zygotes from Setaria viridis

This paper describes a method to isolate gametes, zygotes, and embryos from Setaria viridis for studying fertilization and development in angiosperms.

Excessive assimilation of ammonium by plastidic glutamine synthetase is a major cause of ammonium toxicity in Arabidopsis thaliana

This study identifies plastidic glutamine synthetase 2 (GLN2) as the primary cause of ammonium toxicity in Arabidopsis thaliana by inducing shoot acidity.
