In order to identify genes involved in the development of the central nervous system (CNS) we have undertaken a gain of function screen in the embryonic CNS of Drosophila. Transposable P-elements and the UAS/GAL4 system were used to initiate transcription of genes in a pan-neural pattern using scaGAL4. Over 4100 individual P-element insertion lines were screened with monoclonal antibodies BP102 and...
RNA-dependent processes control gene expression at the post-transcriptional and transcriptional levels in plants. There is a specific group of RNA molecules called small RNAs that play a significant role in the RNA degradation, methylation of genomes, inhibition of translation and, consequently, gene expression regulation. They consist of double ? stranded small interfering RNAs and single-stranded...
A survey of fully-sequenced chloroplast genomes revealed that in land plants there are six tRNA genes that have introns. Moreover, the length of a particular tRNA gene intron remains relatively stable across species. However, in algae, the presence of chloroplast tRNA genes containing introns is exceptional. A survey of mitochondrial plant genomes revealed intron-containing tRNA genes are rather rare...
