At each time, interval, three biological replicates of thrips transmis-, sion were collected daily from 0–10 dpi, as well as 15 dpi, and then subjected to RNA extraction. The IYSV Egyptian isolate was maintained contin-, averaged from three technical replicates) and the, highest and lowest accumulated levels in virus-, value indicated more stable expression. In, summary, our results indicate that the most stable refer-, ence gene for accurate normalization of a target gene in, It has often been suggested that the collective set of PR, genes may be responsible for systemic acquired resis-.

We outline a robust and innovative strategy to identify the most stably expressed control genes in a given set of tissues, and to determine the minimum number of genes required to calculate a reliable normalization factor.

The results were similar to other, studies that have reported the induction of chitinases in, chitinase enzymes of are generally expressed constitu-, tively, with an increase in synthesis observed upon viral, The PR4 family is similar to that of the plant chitinase, family; both contain structural subclasses characterised, by the presence (class I) or absence (class II) of a con-, domain partially shares identity with several chitin-, The PR4 results revealed high expression levels at 1 dpi, with 15.46× expression levels identified in comparison, with the control, after which the expression level de-, creased at 2 dpi and continued to drop dramatically at, 3 dpi. sms or email your required books and have them delvered at your home.

Detailed in silico analysis, accompanied by sequencing of both genomic and cDNA, as well as RT-PCR experiments, provided the correct size of the gene and the exact number, length and positions of introns.
