Abstract
Fungal sexual reproductive modes have markedly high diversity and plasticity, and asexual species have been hypothesized to arise frequently from sexual fungal species. A recent study on the red yeasts provides further support for the notion that sexual ancestors may give rise to shorter-lived asexual species. However, presumed asexual species may also be cryptically sexual, as revealed by other recent studies.
摘要
真菌的有性生殖方式具有显著的多样性和可塑性，并且有假说认为无性物种经常从有性真菌物种中产生。最近对红酵母的研究进一步支持了这样的观点，即有性祖先可能产生寿命更短的无性物种。然而，正如其他最近的研究所示，假定的无性物种也可能是隐性有性的。
