WebEtBr/Dox treatments activate abscisic acid (ABA) signaling. Then ABA promotes the expression of UPRmt genes, like alternative oxidase 1a (AOX1a). A key regulator of ABA signaling, ABA insensitive 5 (ABI5) directly binds to the promoter ofAOX1a, which enhances AOX1a gene transcription. Our study reveals a link between ABA and UPRmt in plants.

WebHow does EtBr stain DNA? Ethidium bromide is the most commonly used dye for DNA and RNA detection in gels. Ethidium bromide is a DNA intercalator, inserting itself between the base pairs in the double helix. Ethidium bromide has UV absorbance maxima at 300 and 360 nm, and an emission maximum at 590 nm. What technique is ethidium bromide used … WebTwo method were implemented in determining the binding constant of EtBr to DNA. The first method was by inputting the absorbance data using a fixed excel worksheet. The main goal was to manipulate the value in cell I24 to be as low as possible. After several trails and error, the final value of cell I24 was 0.00011316 and logK was 3.99.
