Normal cells respond appropriately to various signals, while sustaining proper developmental programs and tissue homeostasis. Inappropriate signal reception, response or attenuation, can upset the normal balance of signaling within cells, leading to dysfunction or tissue malformation. To understand the molecular mechanisms that regulate protein-kinase-based(More)
A leading cause of human birth defects is the incomplete fusion of tissues, often manifested in the palate, heart or neural tube. To investigate the molecular control of tissue fusion, embryonic dorsal closure and pupal thorax closure in Drosophila are useful experimental models. We find that Pvr mutants have defects in dorsal midline closure with(More)
The vast bacteriophage population harbors an immense reservoir of genetic information. Almost 2000 phage genomes have been sequenced from phages infecting hosts in the phylum Actinobacteria, and analysis of these genomes reveals substantial diversity, pervasive mosaicism, and novel mechanisms for phage replication and lysogeny. Here, we describe the(More)
We report here the genome sequences of 38 newly isolated bacteriophages using Gordonia terrae 3612 (ATCC 25594) and Gordonia neofelifaecis NRRL59395 as bacterial hosts. All of the phages are double-stranded DNA (dsDNA) tail phages with siphoviral morphologies, with genome sizes ranging from 17,118 bp to 93,843 bp and spanning considerable nucleotide(More)
Gordonia phages Bowser and Schwabeltier are newly isolated phages infecting Gordonia terrae 3612. Bowser and Schwabeltier have similar siphoviral morphologies and their genomes are related to each other, but not to other phages. Their lysis cassettes are atypically situated among virion tail genes, and Bowser encodes two tyrosine integrases.
Bacteriophages Phinally and Vivi2 were isolated from soil from Pittsburgh, Pennsylvania, USA, using host Gordonia terrae 3612. The Phinally and Vivi2 genomes are 59,265 bp and 59,337 bp, respectively, and share sequence similarity with each other and with GTE6. Fewer than 25% of the 87 to 89 putative genes have predictable functions.
