现代主栽香蕉品种高度依赖营养繁殖，存在遗传基础狭窄、遗传多样性低等问题。芭蕉科现存约80个物种，不同类群在染色体基数（如 n =11、10和9）以及花苞颜色等性状上呈现多样性，是研究植物染色体结构演化和花器官性状分化的理想类群。然而，这些不同染色体基数的演化形成机制、染色体结构变异与花苞颜色分化的内在关联，长期以来缺乏基因组与细胞遗传学层面的直接证据。

Understanding how domestication reshapes brain structure and function remains a fundamental question in evolutionary biology. The hippocampus is a key brain region involved in memory and stress regulation, and it has been thought to undergo "simplification" during domestication. However, the cellular mechanisms underlying these changes remain poorly understood. In a study published in PNAS on Sept

The human body is a marvel of remake and renewal. We regularly replace some of our estimated 37 trillion cells – about 300 billion or 1 percent of our cells each day - with healthy substitutes. We remove damaged or aging, senescent cells and cellular debris from our organs and tissues every second of the day. How important is it that cellular waste be properly removed?

The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the harshest environments on Earth, according to a University of Michigan study.

An international team co-led by the University of Cambridge has mapped every neuron in the male Drosophila fly’s brain and nerve cord, to produce a wiring map of the 166,700 neurons and the millions of connections between them.

Researchers at the Swammerdam Institute for Life Sciences (SILS) of the Faculty of Science have uncovered how mammary-gland cells decide when to activate Wnt4, a gene with a central role in mammary-gland development. Their findings reveal how distant stretches of non-coding DNA work together in three dimensions to control gene activity.

A mule has helped researchers build the most complete reference genomes to date for horses and donkeys, giving scientists access to complex regions of DNA that earlier versions could not fully capture.

标准 DNA 条形码凭借通用引物适配性强和测序成本低等优势，广泛应用于生物多样性保护与溯源等领域。针对近缘种、杂交频繁及近期辐射演化的复杂类群，标准 DNA 条形码因序列变异度有限，分辨率不足，难以满足精准鉴定的需求。尽管基因组浅层测序获取质体全基因组（超级条形码）的策略提升了部分困难类群的鉴别率，但质体基因组的单亲遗传特性使其在杂交渐渗类群分析中存在局限。
Honey bees have long been the model species for studying insect vision. However, new research shows that several smaller bee species might actually have sharper eyesight.
Researchers at UC San Diego have demonstrated that one of biology’s most essential enzymes can accurately read and transcribe an expanded genetic alphabet containing eight DNA letters instead of the four used by all known life.

As it tries to defend itself from stroke, the brain can paradoxically trigger the formation of tiny new clots in minor blood vessels, damaging tissue even after the original culprit has been removed, new research shows. The findings help explain why nearly half of treated stroke patients don’t recover — and identify potential new treatments.

Soil organic carbon dynamics are a key indicator for assessing the success of ecosystem restoration. According to a new study by researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences, soil microorganisms play a critical role in regulating carbon storage in tropical ecosystems undergoing recovery. The study, published in Catena on August 27, showed t
