**Summary:**

A new study published in Science reveals a groundbreaking discovery about two types of fungi, *Botrytis cinerea* (noble rot) and *Sclerotinia sclerotiorum*. Unlike all other known animals, plants, and fungi, these fungi do not have a complete set of chromosomes within a single nucleus of their cells. Instead, the chromosome set is distributed across multiple nuclei. This discovery was made during an experiment attempting to create mutants of *S. sclerotiorum*. The researchers found that each nucleus within an ascospore contained only a subset of the total chromosomes. The discovery challenges existing understanding of chromosome biology and opens new avenues for research into fungal genetics, chromosome allocation, and the evolutionary advantages of this unique chromosomal arrangement.

**Scientists Discover Revolutionary Chromosome Distribution in ‘Noble Rot’ Fungus**

*The Hindu – Science For All* – June 30, 2025

A team of researchers has uncovered a startling anomaly in the genetic makeup of two types of fungi, including *Botrytis cinerea*, known as “noble rot” for its role in producing high-quality sweet wines. The research, published in the journal *Science*, reveals that these fungi defy the conventional understanding of chromosome biology.

Unlike virtually all other life forms, *Botrytis cinerea* and *Sclerotinia sclerotiorum* do not contain a complete set of chromosomes within a single cell nucleus. Instead, the research demonstrates that their chromosomes are distributed across multiple nuclei within the cell.

The discovery was made serendipitously during an experiment aimed at inducing mutations in *S. sclerotiorum*. Scientists were perplexed when mutant colonies lacked non-mutant sectors, which led them to investigate the chromosomal structure of the fungi. Through advanced molecular techniques, the researchers confirmed that each nucleus contained only a partial set of the fungus’s total chromosomes.

“This finding challenges established principles of chromosome biology,” said Dr. D.P. Kasbekar, retired scientist. “It raises fundamental questions about how these fungi allocate chromosomes, maintain genetic integrity during cell division, and restore a complete chromosome set during mating.”

*Botrytis cinerea*’s “noble rot” is prized in winemaking because its infection on grapes concentrates sugars and flavors, resulting in exceptional sweet wines such as Sauternes and Tokaji Aszús. This discovery opens up new avenues for understanding the unique properties of these fungi and potentially manipulating their genetic makeup.

The research team believes this discovery could lead to breakthroughs in fungal biology and genetics, potentially impacting fields ranging from agriculture to medicine. The focus is now on understanding the mechanisms behind this unique chromosomal arrangement and its evolutionary advantage. Scientists working with other model organisms might now be envying those working with noble rot fungi.
