Posterior tail development in the salamander Eurycea cirrigera: exploring cellular dynamics across life stages [0.03%]
环尾螈(Eurycea cirrigera)后尾发育：探索生命阶段的细胞动力学

During embryogenesis, the body axis elongates and specializes. In vertebrate groups such as salamanders and lizards, elongation of the posterior body axis (tail) continues throughout life. This phenomenon of post-embryonic tail elongation v...
Molecular cloning, phylogenetic analysis, and expression patterns of LATERAL SUPPRESSOR-LIKE and REGULATOR OF AXILLARY MERISTEM FORMATION-LIKE genes in sunflower (Helianthus annuus L.) [0.03%]
向日葵(LATERAL SUPPRESSOR样基因和REGULATOR OF AXILLARY MERISTEM FORMATION样基因)的分子克隆、系统发育分析及表达模式研究

The wild sunflower (Helianthus annuus) plants develop a highly branched form with numerous small flowering heads. The origin of a no branched sunflower, producing a single large head, has been a key event in the domestication process of thi...
Expression patterns indicate that BMP2/4 and Chordin, not BMP5-8 and Gremlin, mediate dorsal-ventral patterning in the mollusk Crassostrea gigas [0.03%]
表达模式表明，BMP2/4和Chordin而非BMP5-8和Gremlin介导了珍珠牡蛎Crassostrea gigas的背腹轴图案化

Though several bilaterian animals use a conserved BMP2/4-Chordin antagonism to pattern the dorsal-ventral (DV) axis, the only lophotrochozoan species in which early DV patterning has been studied to date, the leech Helobdella robusta, appea...
Xenopus laevis neuronal cell adhesion molecule (nrcam): plasticity of a CAM in the developing nervous system [0.03%]

Neuron-glial-related cell adhesion molecule (NRCAM) is a neuronal cell adhesion molecule of the L1 immunoglobulin superfamily, which plays diverse roles during nervous system development including axon growth and guidance, synapse formation...
From shoot to leaf: step-wise shifts in meristem and KNOX1 activity correlate with the evolution of a unifoliate body plan in Gesneriaceae [0.03%]
从芽到叶：由苦苣苔科单叶植物进化相关的分生组织和KNOX1活性的逐步变化
Kanae Nishii,Bing-Hong Huang,Chun-Neng Wang et al.
Kanae Nishii et al.
Typical dicots possess equal-sized cotyledons and leaf-bearing shoots topped with a shoot apical meristem (SAM), the source of lateral organs, and where KNOX1 homeobox genes act as key regulators. New World Gesneriaceae show typical cotyled...

The vertebrate endoskeleton results from the piecemeal assembly of bone and cartilage as well as additional types of calcified extracellular matrices produced by seemingly hybrid cell types of intermediate phenotypes between osteoblasts and...

A major problem in developmental genetics is how HOX transcription factors, like Proboscipedia (PB) and Ultrabithorax (UBX), regulate distinct programs of gene expression to result in a proboscis versus a haltere, respectively, when the DNA...
Ontogeny of pioneer neurons in the antennal nervous system of the grasshopper Schistocerca gregaria [0.03%]
非洲迁徙蝗虫触角神经元的发育起源

George Boyan
The nervous system of the antenna of the grasshopper Schistocerca gregaria consists of two nerve tracts in which sensory cells project their axons to the brain. Each tract is pioneered early in embryogenesis by a pair of identified cells lo...
Morphogenesis of the atrichous isorhiza, a type of nematocyst, in Hydra observed with a monoclonal antibody [0.03%]
应用单克隆抗体观察水母状胚层刺丝泡的形态发生过程

We produced a monoclonal antibody, AE03, which recognized mucous granules in the basal disk gland cells in Hydra and the secreted mucus with which they stick onto substrate. AE03 also recognized atrichous isorhizas, one of the four types of...
The profiles of mRNA levels for BHR39, a Bombyx homolog of Drosophila hormone receptor 39, and Bombyx FTZ-F1 in the course of embryonic development and diapause [0.03%]

Teruyuki Niimi et al.
In the silkworm, Bombyx mori, the 5'-upstream region of the sorbitol dehydrogenase (SDH) gene contains nucleotide sequences that might be recognized and bound by steroid hormone receptors such as Drosophila hormone receptor 39 (DHR39) and F...
