摘要

互补性决定基因通过涉及大量天然等位基因的 csd(互补性决定基因)杂合子与同源/半杂合子基因型调节蜜蜂(Apis mellifera)的雌性和雄性发育。这种品系特异性功能提供了一个难得的机会,让我们了解一种尚未被描述的调控机制以及导致这种机制的分子进化路径。我们回顾了最近在理解 Csd 如何识别不同与相同的蛋白质变体、这些变体如何调控下游途径和性分化以及这一机制如何进化并由进化力量塑造等方面取得的进展。最后,我们强调了尽管主要信号多种多样,但性别决定的调控原则是共同的,并证明了品系特异性突变对于描述新进化的功能非常有参考价值。

Honeybees' novel complementary sex-determining system: function and origin.

Complementary sex determination regulates female and male development in honeybees (Apis mellifera) via heterozygous versus homo-/hemizygous genotypes of the csd (complementary sex determiner) gene involving numerous naturally occurring alleles. This lineage-specific function offers a rare opportunity to understand an undescribed regulatory mechanism and the molecular evolutionary path leading to this mechanism. We reviewed recent advances in understanding how Csd recognizes different versus identical protein variants, how these variants regulate downstream pathways and sexual differentiation, and how this mechanism has evolved and been shaped by evolutionary forces. Finally, we highlighted the shared regulatory principles of sex determination despite the diversity of primary signals and demonstrated that lineage-specific mutations are very informative for characterizing newly evolved functions.

期刊介绍: Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology. Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
