ATP-Binding Cassette Transporters Modulate Both Coelenterazine- and D-Luciferin-Based Bioluminescence Imaging

Molecular Imaging, 2011
Bioluminescence imaging (BLI) of luciferase reporters provides a cost-effective and sensitive means to image biological processes. However, transport of luciferase substrates across the cell membrane does affect BLI readout intensity from intact living ...

OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2242-2263, July 2026.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

Firefly luciferase can use L-luciferin to produce light [PDF]

Biochemical Journal, 1996
l-Luciferin is a competitive inhibitor of firefly luciferase with a Ki between 3 and 4 μM. Furthermore l-luciferin can serve as an alternative substrate for light production. Catalysis of l-luciferin can be observed in the absence of, or at low concentrations of, d-luciferin.

The Transcription Factor OsWRKY64 Interacts With OsART1 to Positively Regulate Al Resistance in Rice

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4656-4671, July 2026.
A proposed working model illustrating the cooperative regulation of Al tolerance by OsWRKY64 and OsART1 in rice. Under Al stress conditions in acidic soil, the transcription factor OsART1 directly binds to the promoter of OsWRKY64 to activate its transcription. The synthesized OsWRKY64 protein then physically interacts with OsART1 in the nucleus.

Luciferin Amides Enable in Vivo Bioluminescence Detection of Endogenous Fatty Acid Amide Hydrolase Activity

, 2016
Firefly luciferase is homologous to fatty acyl-CoA synthetases. We hypothesized that the firefly luciferase substrate d-luciferin and its analogs are fatty acid mimics that are ideally suited to probe the chemistry of enzymes that release fatty acid ...
