Putrescine biosynthesis, especially via PyODC, is essential for early conchospore development in Pyropia yezoensis, with exogenous PUT enhancing polarization and meiosis.
- Why it matters: Understanding the molecular mechanisms of conchospore development is crucial for improving germling yields in Pyropia aquaculture, which currently depends on natural spore collection.
- What they did: The study analyzed gene expression profiles, identified key PUT biosynthesis genes, and used exogenous PUT, inhibitors, and gene silencing to investigate their roles during early development stages.
- The result: Findings demonstrate that PyODC and PUT are vital for conchospore polarization and meiosis, providing strategies for metabolic regulation to optimize seedling production.
