Neurospora crassa has long served as a key fungal genetics model, facilitating discoveries like the "one gene, one enzyme" hypothesis. It produces many conidia, mostly with two or three nuclei and each nucleus was once thought to contain a full haploid genome. Using flow cytometry and FISH, we found that N. crassa haploid chromosomes are divided among nuclei, each conidium is haploid - challenging the "one nucleus, one whole genome" rule.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
