That's amazing! ONCE IN 80 YEARS 😍🤩
Puya raimondii, queen of the Andes, is the largest species of bromeliad, reaching up to 15 m (50 ft) in height and carry 20,000 flowers. It is native to the high Andes of Bolivia and Peru. It has been considered a Protocarnivorous plant (ensnaring birds).
Its reproductive cycle lasts approximately 80 years.
Now researchers report its first genome to promote its conservation and evolutionary study. Comparative genomics showed P. raimondii diverged from Ananas comosus about 14.8 million years ago, and the long terminal repeats were likely to contribute to the genus diversification in last 3.5 million years. The gene families related to plant reproductive development and stress responses significantly expanded in the genome. At the same time, gene families involved in disease defense, photosynthesis and carbohydrate metabolism significantly contracted, which may be an evolutionary strategy to adapt to the harsh conditions in high Andes.
