In Drosophila, the sensory mother cells of macrochaetes are chosen from among the mitotically quiescent clusters of cells in wing imaginal discs, where other cells are proliferating. The pattern of cyclin A, one of the G2 cyclins, reveals t...
Cell migration within the embryonic limb primordium of Drosophila as revealed by a novel fluorescence method to visualize mRNA and protein [0.03%]
一种新的荧光方法用于可视化信使核糖核酸和蛋白质揭示果蝇胚肢原基中细胞的迁移现象

We report a new technique using fluorescent probes to detect a mRNA and a protein simultaneously in the Drosophila embryo. For in situ hybridization, 3-hydroxy-N-2'-biphenyl-2-naphthalenecarboxamide phosphate ester (HNPP)/Fast Red TR was us...
Putative Krüppel target gene of novel sequence expressed in Drosophila VO5 muscle precursors [0.03%]

C Hartmann
Krüppel (Kr), a member of the gap class of Drosophila segmentation genes, encodes a zinc finger-type transcription factor. After blastoderm formation, Kr is expressed in various spatially and temporally restricted patterns of the developin...
A retinoid-binding lipocalin, Xlcpl1, relevant for embryonic pattern formation is expressed in the nervous system of Xenopus laevis [0.03%]

The importance of retinoids in early development has been increasingly recognized during the past decade. Their transport and action are mediated by extracellular, intracellular and nuclear proteins. Here we describe the isolation and chara...

pax-6 is thought to be a master control gene of eye development in species ranging from insects to mammals. We have isolated a pax-6 cDNA homolog of the newt, Cynops pyrrhogaster. RT-PCR and sequence analyses predicted four alternatively sp...
Two zebrafish homologues of the Drosophila neurogenic gene groucho and their pattern of transcription during early embryogenesis [0.03%]
两个斑马鱼基因grocho的同源物及其在早期胚胎发生过程中的转录模式
Corinna Wülbeck,J A Campos-Ortega
Corinna Wülbeck
GROUCHO is a Drosophila nuclear protein with structural similarity to the transcriptional repressor TUP1. Drosophila GROUCHO forms complexes with bHLH proteins of the HAIRY-ENHANCER OF SPLIT [-E(SPL)] family, that then act as repressors, fo...
Temporal alteration of dose-dependent response to activin in newt animal-cap explants [0.03%]
蝾螈动物极组织中Activin剂量效应的时相变化

Kiyoaki Sone et al.
In this study, we examined the dose-dependent responses of animal-pole cells of the Japanese newt, Cynops pyrrhogaster, to activin. Cynops has a slower developmental rate and a simpler animal cap structure than Xenopus. These features enabl...
Requirement of teashirt (tsh) function during cell fate specification in developing head structures in Drosophila [0.03%]
转座子基因teashirt在果蝇头部发育中细胞命运决定时的功能要求

Jyoti Bhojwani
The homeotic gene teashirt (tsh) is known to regulate segmental identity of the trunk region of the Drosophila embryo. Here we report a requirement for tsh function in the development of adult head structures. Animals homozygous for a viabl...
Lineage and fate in Drosophila: role of the gene tramtrack in sense organ development [0.03%]
果蝇感觉器官的形成与基因tramtrack的关系
Geneviève Ramaekers,Kazuya Usui,Akiko Usui-Ishihara et al.
Geneviève Ramaekers et al.
The tactile bristles of the fly comprise four cells that originate from a single precursor cell through a fixed lineage. The gene tramtrack (ttk) plays a crucial role in defining the fates of these cells. Here we analyse the normal pattern ...
Inductive interactions required for mesodermal differentiation in Bufo arenarum gastrulae [0.03%]

Dorso-marginal epithelium, a distinct crescent-shaped region in the early gastrula of Bufo arenarum, appears after involution as a narrow dorso-median strip of archenteric endoderm close to the notochord. In explant cultures, this layer sho...
