Title Imaging Promoter Assay of Adenylyl Cyclase A Gene in Dictyostelium discoideum during Fruiting Body Formation by Dual-Color Bioluminescence Microscopy
Journal Bioluminescence - Technology and Biology
Abstract Cyclic adenosine monophosphate (cAMP), which is derived from adenosine triphosphate through adenylyl cyclase A (acaA), acts as an intracellular secondary messenger and an extracellular chemotactic substance in important biological processes. In the social amoebae Dictyostelium discoideum, cAMP mediates cell aggregation, development, and differentiation to spore and stalk cells during fruiting body formation. The acaA gene is transcribed under the control of three different alternative promoters. This study aimed to develop a promoter assay for acaA in D. discoideum using bioluminescence microscopy. Here, we inserted green- and red-emitting luciferase genes into downstream of promoter regions 1 and 3, respectively. Promoter activities were visualized by bioluminescence microscopy. We confirmed the differential expression of acaA under the control of promoters 1 and 3 at the different stages of D. discoideum development. We also demonstrated the application of dual-color bioluminescence imaging in the development of an imaging promoter assay.
