Part of the TrxZ gene of A. thaliana to synthesize dsRNA for RNAi
This is a section of TrxZ gene of Arabidopsis thaliana to synthesize dsRNA for RNAi. To product dsRNA, this sequence is inserted in L4440 plasmid, and transformed into HT115(DE3).

purpose

Trx-Z is a gene responsible for chloroplast formation during early development in Arabidopsis thaliana. Silencing this genes is whitening leaf of Arabidopsis thaliana[1].

Usage and Biology

RNAi
RNAi (RNA interference) is a process in which externally introduced dsRNA suppresses the expression of genes that have complementary sequences to the dsRNA.

L4440
L4440 is a plasmid vector having two convergent T7 promoters adjacent to the multi-cloning site. By inserting a portion of the target gene sequence into the multi-cloning site of this plasmid, the target sequence is transcribed from both sides, and dsRNA can be obtained when both parts anneal.

HT115(DE3)
HT115 (DE3) is an RNase III-deficient E. coli strain that has been modified to express T7 RNA polymerase from an IPTG-inducible promoter. It lacks dsRNA-specific RNase III, which allows it to produce high levels of specific dsRNA. These attributes allow HT115 (DE3) to be a promising strain for the preparation of large amounts of viral dsRNA in vivo.
