Complete sequence of a eukaryotic regulatory gene.

DNA methylation--a regulatory signal in eukaryotic gene expression.

Chromatin structure and regulation of the eukaryotic regulatory gene GAL80.

The chromatin structure around the 5' end of the yeast regulatory gene GAL80 has been determined. The chromatin organization is very similar to that on the 5' regions of the GAL1-10 structural genes: a constitutive hypersensitive region containing the upstream activating sequence (UAS) element, and nucleosomes around this hypersensitive region. The downstream nucleosome, which is a positioned n...

Complete Genomic Sequence of a Strain of Tomato Yellow Leaf Curl Virus from Iran

Background and Aims: Tomato yellow leaf curl virus (TYLCV) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. In this study, the complete sequence of TYLCV isolate from Hormozgan province, Iran and its recombination evsent was determined. Methods: TYLCV infected tomato was collected from Hormozgan province. Total D...

Cross-regulation and interaction between eukaryotic gene regulatory processes

Regulation of genes is fundamental to all living processes and can be exerted at many sequential steps. We studied several eukaryotic gene regulatory mechanisms with an emphasis on understanding the interplay between regulatory processes on a genome-wide scale. Gene splicing involves the joining of exonic RNA stretches from within a precursor messenger RNA (mRNA). Splicing typically occurs co-t...

Complete nucleotide sequence of a sea urchin actin gene

We have determined the complete nucleotide sequence of a sea urchin actin gene, including the entire protein-coding sequence, introns and approximately 500 and 700 nucleotides adjacent to protein-coding-sequence on the 5' and 3' sides, respectively. This gene is split between codons 121 and 122 and within codon 204 by two introns which are 233 and 181 nucleotides in length, respectively. Compar...
