Ectocarpus is a genus of filamentous, marine brown algae. Brown algae belong to the stramenopiles, a large supergroup of organisms that are only distantly related to animals, land plants and fungi. Brown algae are also one of only a small n...
Genomic resources and toolkits for developmental study of whip spiders (Amblypygi) provide insights into arachnid genome evolution and antenniform leg patterning [0.03%]

Background: The resurgence of interest in the comparative developmental study of chelicerates has led to important insights, such as the discovery of a genome duplication shared by spiders and scorpions, inferred to have ...
Evolution and development of three highly specialized floral structures of bee-pollinated Phalaenopsis species [0.03%]
蜜蜂授粉的蝴蝶兰三钟高度特化的花部结构的演化与发育

Dewi Pramanik et al.
Background: Variation in shape and size of many floral organs is related to pollinators. Evolution of such organs is driven by duplication and modification of MADS-box and MYB transcription factors. We applied a combinati...
Activin/Nodal signaling mediates dorsal-ventral axis formation before third quartet formation in embryos of the annelid Chaetopterus pergamentaceus [0.03%]

Background: The clade of protostome animals known as the Spiralia (e.g., mollusks, annelids, nemerteans and polyclad flatworms) shares a highly conserved program of early development. This includes shared arrangement of c...
Expression of smooth muscle-like effectors and core cardiomyocyte regulators in the contractile papillae of Ciona [0.03%]
斑海鞘收缩状乳头中类似平滑肌的效应子和中心心肌细胞调节子的表达

The small teleost fish Astyanax mexicanus has emerged as an outstanding model for studying many biological topics in the context of evolution. A major attribute is conspecific surface dwelling (surface fish) and blind cave dwelling (cavefis...

The transition of life from single cells to more complex multicellular forms has occurred at least two dozen times among eukaryotes and is one of the major evolutionary transitions, but the early steps that enabled multicellular life to evo...
Can the anatomy of abnormal flowers elucidate relationships of the androecial members in the ginger (Zingiberaceae)? [0.03%]
异常花朵的解剖能否阐明姜科花药成员之间的关系？

Xiumei Li et al.
Background: Interpretation of the floral structure of Zingiberaceae has long concentrated on the relationships of the androecial members. It suggested that labellum is composed of two structures rather than three or five,...
