Phyllopod at the intersection of developmental signalling pathways
One of the striking findings in developmental genetics over the past two decades is the realization that a very small number of conserved signalling pathways directs most, if not all, aspects of development of multicellular organisms, by transmitting extracellular signals to the cell nucleus, to modify gene expression programs. How can such a small number of distinct pathways regulate an amazin...
متن کاملPenaeus indicus (Decapoda: Crustacea)
A survey was carried out on the prevalence of bacteria and ciliate protozoan of Pellaells indiclls obtained from Ennore estuary, Chennai (Madras), India from November 1989 to July 1992. The study r~vealed the occurrence of Vibrio parahaemolyticus, V. VUlllijiCUS, V. harvey;, V. allguillarum, V. damsela, Pseudomollas sp., P. aemgillo.\'{/ and a tilamentous bacterium Leucothrix sp. This study als...
متن کاملphyllopod functions in the fate determination of a subset of photoreceptors in drosophila
phyllopod (phyl) encodes a novel protein required for fate determination of photoreceptors R1, R6, and R7, the last three photoreceptors to be recruited into the ommatidia of the developing Drosophila eye. Genetic data suggests that phyl acts downstream of Ras1, raf, and yan to promote neuronal differentiation in this subset of photoreceptors. Ectopic expression of phyl in the cone cell precurs...
متن کاملA Phyllopod-Mediated Feedback Loop Promotes Intestinal Stem Cell Enteroendocrine Commitment in Drosophila
The intestinal epithelium in the Drosophila midgut is maintained by intestinal stem cells (ISCs), which are capable of generating both enterocytes and enteroendocrine cells (EEs) via alternative cell fate specification. Activation of Delta-Notch signaling directs ISCs for enterocyte generation, but how EEs are generated from ISCs remains poorly understood. Here, we identified Phyllopod (Phyl) a...
متن کاملRegulation of Notch and Wingless signalling by phyllopod, a transcriptional target of the EGFR pathway.
Spatial and temporal control of Notch and Wingless (Wg) pathways during development is regulated at multiple levels. Here, we present an analysis of Phyllopod as a coordinated regulator of these two critical signal transduction pathways. Phyl specifically helps traffic Notch and Wg pathway components within early endocytic vesicles, thereby controlling the amount of processed signal available f...
