Description
Alveena Zulfiqar and co-authors study how the titan arum, or corpse flower, makes heat and its rotting smell in a 2024 paper. The plant produces the largest unbranched flower structure in the world, blooms rarely for a few days, warms up, and smells of decay to attract pollinators. Little was known about the plant chemistry behind either trait.
Gene and chemical analyses showed heat production tracks with bypass steps in the cell energy chain, plus sugar transport and use. The main odor compounds are sulfur based, built from the amino acid methionine through sulfur pathways the team mapped. A second odor ingredient, putrescine, was newly recognized, and both ingredients fell fast as heating peaked.
