Diploid-dominant life cycles characterize the early evolution of Fungi

mycolabadmin

Scientists studied the evolutionary history of fungi by sequencing the genomes of 69 water-dwelling fungi. They discovered that contrary to what textbooks say, many fungi actually have diploid-dominant life cycles (like animals) rather than haploid-dominant ones (with single copies of genes). The ancient ancestor of all fungi was likely diploid, and different fungal groups lost this trait at different times in evolution.

Digging into the evolutionary history of the fungus-growing-ant symbiont, Escovopsis (Hypocreaceae)

mycolabadmin

Researchers studied fungi called Escovopsis that live in ant colonies and interact with the fungi that ants farm for food. By examining 309 fungal samples from across Central and South America, they discovered that these fungi originated 57 million years ago but only started living with the ants about 38 million years ago. Over time, Escovopsis evolved to grow faster and reproduce more efficiently, likely helping it survive in the ant colony environment.

Large-scale phylogenomic insights into the evolution of the Hymenochaetales

This study examined the evolutionary history of over 1,200 species of wood-decomposing and disease-causing fungi called Hymenochaetales using genetic analysis of 171 fungal genomes. The researchers found that these fungi likely originated in temperate regions of Asia during the age of dinosaurs and gradually spread worldwide, changing their physical forms as they diversified. The research provides important insights into how major groups of fungi evolved and adapted over millions of years.
