Scientists Discover Molecular Mechanism Behind Pineapple Peel Coloration
July 31, 2024| |
Researchers from the South China Agricultural University, Tropical Crops Genetic Resources Institute, Chinese Academy of Tropical Agricultural Sciences, and Guangdong Eco-Engineering Polytechnic have identified a key transcription factor specifically expressed in the pineapple peel that regulates anthocyanin accumulation.
The researchers identified AcMYB266 as a key transcription factor expressed in pineapple peel that regulates anthocyanin accumulation. Through transgenic experiments in pineapple, Arabidopsis, and tobacco, they identified that overexpression of AcMYB266 leads to increased anthocyanin levels, resulting in red pigmentation.
The study also found that variations in the promoter sequences of AcMYB266 contribute to different red coloration patterns observed in various pineapple varieties. The identification of AcMYB266 and its role in anthocyanin accumulation could make possible the development of new pineapple varieties with enhanced aesthetic and nutritional value.
