This paper introduces a GreenGate-compatible vector toolkit for efficient recombinant protein purification from E. coli by enabling modular assembly of affinity tags.

This study identifies GEF8 and GEF9 as essential for initiating pollen germination in Arabidopsis by polarly activating ROPs and altering Ca2+ signaling.

This study uses 3D live imaging in Arabidopsis to show that pollen tubes invade synergid cells by forming a peritubular membrane, with calcium signaling playing a key role in this process.
