Dear Editor, Drosophila oogenesis is of great interest because it represents an excellent model system to study a number of fascinating biological processes, such as stem cell regulation, germ cell meiosis and oocyte...
Here, we provide data suggesting that the absence of silencing of the ectopic reprogramming factors used to reprogram somatic cells to induced pluripotent stem cells (iPSCs) may predispose iPSCs to genomic instabili...
We thank Mary Bryk and Timothy Hall for critical suggestions to improve the manuscript,David Stelly and Keerti Rathore for assistance in GFP localization studies in onion cells,and Stanislav Vitha in the Microscopy and Imaging Center at Texas A&M University for technical support for epifluorescence microscopic image analysis in the transgenic plants.The work is supported by grants from the National Institutes of Health(GM067015);the National Science Foundation Plant Genome Research Program(DBI0077774)to Z J C.
Arabidopsis thaliana histone deacetylase 1 (AtHD1 or AtHDA19), a homolog ot yeast RPD3, is a global regulator ot many physiological and developmental processes in plants. In spite of the genetic evidence for a role ...
The study of gene function in filamentous fungi is a field of research that has made great advances in very recent years. A number of transformation and gene manipulation strategies have been developed and applied to ...
A vector-based RNAi expression system was developed using the Xenopus tropicalis U6 promoter, which transcribes small RNA genes by RNA polymerase Ⅲ. The system was first validated in a Xenopus laevis cell line, desig...
In eukaryotic organisms cellular fate and tissue specific gene expression are regulated by the activity of proteins known as transcription factors that by interacting with specific DNA sequences direct the activation ...
Classical methyl-CpG binding proteins contain the conserved DNA binding motif methyl-cytosine binding domain(MBD), which preferentially binds to methylated CpG dinucleotides. These proteins serve as transcriptional re...
The recent development of gene transfer approaches in plants and animals has revealed that transgene can undergo silencing after integration in the genome. Host genes can also be silenced as a consequence of the prese...
