Plants are essential for human survival. Over the past three decades, work with the reference plant Arabidopsis thaliana has significantly advanced plant biology research. One key event was the sequencing of its genome 25 years ago, which f...

Nitrogen is widely recognized as a crucial element for plants due to its role as a fundamental building block for essential macromolecules such as nucleic acids, amino acids, and proteins. In most soils, nitrogen primarily exists in inorgan...

In 2022, Dr. Cheng-Hsun Ho and his laboratory team published the first fluorescent resonance energy transfer (FRET) sensor for detecting nitrate ions (NO3–) within plant organisms in the journal Science Advances (Full article link: https://...

A team led by Dr. Cheng-Hsun Ho at the Agricultural Biotechnology Research Center has developed for the first time, a genetically engineered fluorescence resonance energy transfer (FRET) nitrate biosensor that measures the levels of nitrate...

The NRT1/PTR FAMILY (NPF) in Arabidopsis (Arabidopsis thaliana) plays a major role as a nitrate transporter. The first nitrate transporter activity biosensor NiTrac1 converted the dual affinity nitrate transceptor NPF6.3 into fluorescence a...

The understanding of signaling and metabolic processes in multicellular organisms requires knowledge of the spatial dynamics of small molecules and the activities of enzymes, transporters, and other proteins in vivo, as well as biophysical ...
