Attractive petals are an integral component of animal-pollinated flowers and in many flowering plant species are restricted to the second floral whorl. Interestingly, multiple times during angiosperm evolution, petaloid characteristics have...
Molecular mechanisms of EGF signaling-dependent regulation of pipe, a gene crucial for dorsoventral axis formation in Drosophila [0.03%]
EGF信号依存的pipe基因(该基因对果蝇背腹轴的形成至关重要)调控的分子机制

Martin Technau
During Drosophila oogenesis the expression of the sulfotransferase Pipe in ventral follicle cells is crucial for dorsoventral axis formation. Pipe modifies proteins that are incorporated in the ventral eggshell and activate Toll signaling w...
Morphogenesis of Pseudopallene sp. (Pycnogonida, Callipallenidae) II: postembryonic development [0.03%]
球海蜘蛛假伪球海蛛属(Pycnogonida, Callipallenidae)的形态发生II:后胚胎发育

Georg Brenneis
Pycnogonida (sea spiders) are bizarre marine arthropods that are nowadays most frequently considered as being the sister group to all other chelicerates. The majority of pycnogonid species develops via a protonymphon larva with only three p...

球海蜘蛛亚目扁脸海蛛科假伪海蛛种属(Pseudopallene sp.)的形态发生:胚胎发育
Georg Brenneis,Claudia P Arango,Gerhard Scholtz
Georg Brenneis
Embryonic development of Pycnogonida (sea spiders) is poorly understood in comparison to other euarthropod lineages with well-established model organisms. However, given that pycnogonids potentially represent the sister group to chelicerate...
Convergent, modular expression of ebony and tan in the mimetic wing patterns of Heliconius butterflies [0.03%]
斑蝶翅膀拟态图案中ebony和tan的汇聚及模块化表达

Laura C Ferguson
The evolution of pigmentation in vertebrates and flies has involved repeated divergence at a small number of genes related to melanin synthesis. Here, we study insect melanin synthesis genes in Heliconius butterflies, a group characterised ...
Mathematics and biology: a Kantian view on the history of pattern formation theory [0.03%]

Siegfried Roth
Driesch's statement, made around 1900, that the physics and chemistry of his day were unable to explain self-regulation during embryogenesis was correct and could be extended until the year 1972. The emergence of theories of self-organisati...
Post-embryonic functions of HSP90 in Tribolium castaneum include the regulation of compound eye development [0.03%]
热休克蛋白90在赤拟谷盗胚胎后发育中的功能包括复合眼的发育调控
Eileen Knorr,Andreas Vilcinskas
Eileen Knorr
Heat shock protein 90 (HSP90) belongs to a family of conserved chaperons with multiple roles in stress adaptation and development, including spermatogenesis, oogenesis and embryogenesis in insects. In the red flour beetle, Tribolium castane...
An abnormally developed embryo of the pill millipede Glomeris marginata that lacks dorsal segmental derivatives [0.03%]
一种异常发育的 Pill 千足虫(Glomeris marginata)胚胎缺少背侧节段派生物

The body of arthropods is subdivided in serially homologous units, the so-called segments. In many arthropods, ventral and dorsal segmental tissue typically is aligned in parallel, but is dependent on different genetic inputs. In the pill m...
Brain development in the yellow fever mosquito Aedes aegypti: a comparative immunocytochemical analysis using cross-reacting antibodies from Drosophila melanogaster [0.03%]
埃及伊蚊(Aedes aegypti)的大脑发育:与果蝇(Drosophila melanogaster)交叉反应抗体的免疫细胞化学分析
