Decoded the genome of the stinky fruit
Singapore scientists have published the results of sequencing of the genome of durian — a tropical fruit with a hard shell, soft flesh and a sharp specific smell. About their work they reported in the journal Nature Genetics. Briefly reported by EurekAlert!
“I like genetics, of course, interested in the genome of the durian: what gene gives it such a pungent smell as he develops his prickly rind,” commented one of the authors, Professor of the Singapore national cancer centre for the study of Those Bean tin.
The authors investigated the separate species of durian called Musang King. She is known for her soft flesh and a strong smell. The scientists found that the genome of the fruit contains about 46 thousand genes, more than double the human genome. Using the latest data, geneticists have traced the evolution of durian and his relationship with cacao 65 million years ago.
Having examined the various parts of a plant, geneticists have identified a group of genes encoding methionine-gamma-lyase — proteins that regulate the synthesis of volatile aromatic compounds, including sulfur.
Thus, were right, those who smell of durian could distinguish the smell of sulfur.
Scientists suggest that in nature, pungent smell of durian needs to attract animals and thus help the plant to spread. However, many species of durian are under threat of extinction due to a General decline of biodiversity.
The study was conducted on the means of anonymous lovers of durian.
