Identification of receptor-tyrosine-kinase-signaling target genes reveals receptor-specific activities and pathway branchpoints during Drosophila development.

abstract：:Fruit flies of the genus Drosophila have been an attractive and effective genetic model organism since Thomas Hunt Morgan and colleagues made seminal discoveries with them a century ago. Work with Drosophila has enabled dramatic advances in cell and developmental biology, neurobiology and behavior, molecular biology, ...
