Key Points

  • Chloroplast budding is crucial for increasing beta-carotene transport into the cytoplasm, enhancing astaxanthin production.
  • This process reveals effective transport mechanisms and offers a novel target for boosting carotenoid accumulation in microalgae.
  • Maximizing astaxanthin production could significantly impact industries like aquaculture and cosmetics, due to its high commercial value.
  • Further exploration of microalgal metabolism may lead to improved methods for astaxanthin enrichment in biotechnological applications.

Abstract

β-Carotene, the precursor of the high-value carotenoid astaxanthin, is transported into the cytoplasm via chloroplast membrane budding.
