Transient expression of coding and non-coding regions of PVY confer resistance to virus infection
One of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific RNA-dependent silencing pathway termed post-transcriptional gene silencing(PTGS). In this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. Potato VirusY (PVY) is one of the mostdamaging viruses of potato, infecting...
متن کاملInduction of RNA interference in Caenorhabditis elegans by RNAs derived from plants exhibiting post-transcriptional gene silencing.
The term 'gene silencing' refers to transcriptional and post-transcriptional control of gene expression. Related processes are found across kingdoms in plants and animals. We intended to test whether particular RNA constituents of a silenced plant can induce silencing in an animal. We generated Nicotiana benthamiana lines that expressed green fluorescent protein (GFP) from a transgene. Plants i...
متن کاملCircadian rhythms and post-transcriptional regulation in higher plants
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps. One of the key steps involved at the RNA level is post-transcriptional regulation, which ensures a correct control on the different amounts and types of mRNA that will ultimately define th...
متن کاملRNA interference: traveling in the cell and gaining functions?
Double-stranded RNA can induce the degradation of homologous RNAs in organisms as diverse as protozoa, animals, plants and fungi, resulting in post-transcriptional gene silencing. But in some species, RNA-mediated processes can also lead to translational repression, DNA methylation, heterochromatin formation or DNA elimination. In some situations, amplification of the 'trigger' double-stranded ...
متن کاملPost-transcriptional cosuppression of beta-1,3-glucanase genes does not affect accumulation of transgene nuclear mRNA.
Silencing of a Nicotiana plumbaginifolia beta-1,3-glucanase (gn1) transgene in tobacco line T17 occurs in homozygous and in haploid plants with one transgene locus dosage per chromosome set. We have previously shown that the silent state is manifested by a reduced gn1 steady state mRNA level and results from a post-transcriptional process that is under developmental control in homozygous T17 pl...
