The basic helix-loop-helix transcription factor twist plays a key role during mesoderm development in Bilateria. In this study, we identified a twist ortholog in the polychaete annelid Platynereis dumerilii and analyze its expression during...
Duplicated STM-like KNOX I genes act in floral meristem activity in Eschscholzia californica (Papaveraceae) [0.03%]
加州罂粟（罂粟科）花分生组织活性中的重复STM样KNOX I基因作用

Angelika Stammler et al.
In angiosperms, the shoot apical meristem is at the origin of leaves and stems and is eventually transformed into the floral meristem. Class I knotted-like homeobox (KNOX I) genes are known as crucial regulators of shoot meristem formation ...
The expression pattern of the genes engrailed, pax6, otd and six3 with special respect to head and eye development in Euperipatoides kanangrensis Reid 1996 (Onychophora: Peripatopsidae) [0.03%]
泛足纲目鞭足目坎培尔巨钩刺螠科基因en、pax6、otd和six3的表达模式及其在头部和眼睛发育中的作用

Bo Joakim Eriksson
The genes otd/otx, six3, pax6 and engrailed are involved in eye patterning in many animals. Here, we describe the expression pattern of the homologs to otd/otx, six3, pax6 and engrailed in the developing Euperipatoides kanangrensis embryos....
Expression pattern of Piwi-like genes in adult Myzostoma cirriferum (Annelida) [0.03%]
螠鱼(Myzostoma cirriferum)(环节动物)成体Piwi基因表达模式分析
Anne Weigert,Conrad Helm,Harald Hausen et al.
Anne Weigert et al.
Piwi-like genes are a subgroup of Argonaute genes which participate as gene regulators by gene silencing. In most bilaterians, such as mouse, human, insects, and zebrafish, their expression is mostly limited to gonadal stem cells. But there...

Bone morphogenetic proteins (BMPs) play key roles in development. In Drosophila melanogaster, there are three BMP-encoding genes: decapentaplegic (dpp), glass bottom boat (gbb) and screw (scw). dpp and gbb are found in all groups of insects...

Two primary ciliary bands, the prototroch and metatroch, are required for locomotion and in the feeding larvae of many spiralians. The metatroch has been reported to have different cellular origins in the molluscs Crepidula fornicata and Il...
An efficient microinjection method for unfertilized eggs of Asian amphioxus Branchiostoma belcheri [0.03%]
亚洲文昌鱼Branchiostoma belcheri未受精卵显微注射的高效方法
Xin Liu,Guang Li,Jun Feng et al.
Xin Liu et al.
Amphioxus is a promising model animal for evolutionary and developmental studies. However, as an emerging model organism, amphioxus lacks most molecular techniques applied in other well-developed model animals. Microinjection is a powerful ...
Exploring the effects of gene dosage on mandible shape in mice as a model for studying the genetic basis of natural variation [0.03%]
利用小鼠下颌形态研究基因剂量效应以探讨自然变异的遗传基础
Louis Boell,Luisa F Pallares,Claude Brodski et al.
Louis Boell et al.
Mandible shape in the mouse is a complex trait that is influenced by many genetic factors. However, little is known about the action of single genes on adult mandible shape so far, since most developmentally relevant genes are already requi...
Glia associated with central complex lineages in the embryonic brain of the grasshopper Schistocerca gregaria [0.03%]

We have investigated the pattern of glia associated with central complex lineages in the embryonic brain of the grasshopper Schistocerca gregaria. Using the glia-specific marker Repo, we identified glia associated externally with such linea...
RNA interference in the appendicularian Oikopleura dioica reveals the function of the Brachyury gene [0.03%]
利用文昌鱼Oikopleura dioica的RNA干扰揭示Brachyury基因的功能
Tatsuya Omotezako,Atsuo Nishino,Takeshi A Onuma et al.
Tatsuya Omotezako et al.
The appendicularian Oikopleura dioica is a chordate that has a remarkably simple adult body with small cell number. Its transparency, stereotyped cell lineages, short life cycle, and small genome make it a promising new experimental model o...
