Title:The function of a newly identified retina homeobox-containing gene,RxL in Xenopus retinal development
Content: There are two interesting themes in study of eye developement. One is the specification of eye field from the neural sytem, and another is retinnogenesis, namely the generation of different types of retinal cells . Each process is related to the regulation of certain kinds of genes. In this research, a new gene has been identified in Xenopus. To understand its function, we use morpholino to knock down the gene's expression or overexpress this gene in Xenopus embryo. The results showed that this gene is essential for the development of photoreceptor cells.
