Ekin Tilic et al.
Background: This study sheds light on the genetic blueprints of chaetogenesis (bristle formation), a complex biomineralization process essential not only for the diverse group of bristle worms (annelids) but also for othe...
Loss of staminodes in Aquilegia jonesii reveals a fading stamen-staminode boundary [0.03%]
Aquilegia jonesii雄蕊数目减少揭示了花丝和雄蕊柄边界的模糊化现象

The modification of fertile stamens into sterile staminodes has occurred independently many times in the flowering plant lineage. In the genus Aquilegia (columbine) and its closest relatives, the two stamen whorls closest to the carpels hav...
An atlas of spider development at single-cell resolution provides new insights into arthropod embryogenesis [0.03%]
单细胞分辨率的蜘蛛发育图谱为节肢动物胚胎发生提供了新的见解

Daniel J Leite et al.
Spiders are a diverse order of chelicerates that diverged from other arthropods over 500 million years ago. Research on spider embryogenesis, particularly studies using the common house spider Parasteatoda tepidariorum, has made important c...
Histone deacetylases regulate organ-specific growth in a horned beetle [0.03%]
组蛋白去乙酰基酶调节角甲虫的器官特异性生长
Yonggang Hu,Jordan R Crabtree,Anna L M Macagno et al.
Yonggang Hu et al.
Background: Nutrient availability is among the most widespread means by which environmental variability affects developmental outcomes. Because almost all cells within an individual organism share the same genome, structu...

A challenge for evolutionary developmental (evo-devo) biology is to expand the breadth of research organisms used to investigate how animal diversity has evolved through changes in embryonic development. New experimental systems should coup...
Development of the hyolaryngeal architecture in horseshoe bats: insights into the evolution of the pulse generation for laryngeal echolocation [0.03%]
马铁蹄蝠的喉部构造发育：对声纳脉冲产生进化的一种见解
Taro Nojiri,Masaki Takechi,Toshiko Furutera et al.
Taro Nojiri et al.
Background: The hyolaryngeal apparatus generates biosonar pulses in the laryngeally echolocating bats. The cartilage and muscles comprising the hyolarynx of laryngeally echolocating bats are morphologically modified compa...

The Middle Cambrian fossil Pikaia has a regular series of vertical bands that, assuming chordate affinities, can be interpreted as septa positioned between serial myotomes. Whether Pikaia has a notochord and nerve cord is less certain, as t...
Genome-wide identification and spatiotemporal expression analysis of cadherin superfamily members in echinoderms [0.03%]
棘皮动物粘附分子超家族的基因组识别及时空表达分析
Macie M Chess,William Douglas,Josiah Saunders et al.
Macie M Chess et al.
Background: Cadherins are calcium-dependent transmembrane cell-cell adhesion proteins that are essential for metazoan development. They consist of three subfamilies: classical cadherins, which bind catenin, protocadherins...
Nematostella vectensis exemplifies the exceptional expansion and diversity of opsins in the eyeless Hexacorallia [0.03%]
无眼六放珊瑚净铃虫(Nematostella vectensis)视黄蛋白的特异扩张和多样性为例证
Kyle J McCulloch,Leslie S Babonis,Alicia Liu et al.
Kyle J McCulloch et al.
Background: Opsins are the primary proteins responsible for light detection in animals. Cnidarians (jellyfish, sea anemones, corals) have diverse visual systems that have evolved in parallel with bilaterians (squid, flies...
