摘要

粉蚧B染色体通过模仿母体染色质状态来避免父系基因组消除（PGE），从而确保其传播。Vea等人进行了详细的基因组和转录组学分析，强调了组蛋白乙酰转移酶可能驱动这种行为。他们的发现阐明了自私的染色体策略和遗传系统的表观遗传操纵。

Selfish B chromosome evades genome elimination.

The mealybug B chromosome evades paternal genome elimination (PGE) by mimicking maternal chromatin states, ensuring its transmission. Vea et al. conducted a detailed genomic and transcriptomic analysis, highlighting a histone acetyltransferase potentially driving this behavior. Their findings illuminate selfish chromosome strategies and epigenetic manipulation of inheritance systems.

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.
