Data for characterization of SALK_084889, a T-DNA insertion line of Arabidopsis thaliana

In this article we report the identification of T-DNA (transfer DNA) insertion sites within two different gene regions in the genome of an Arabidopsis mutant line, SALK_084889. The T-DNA positions are in the 3' UTR (untranslated region) of DREB2A (Dehydration-responsive element-binding protein 2A) (AT5G05410) and promoter of LOX1 (Lipoxygenase 1) (AT1G55020) as determined by DNA-PCR and sanger sequencing. The expression levels of DREB2A and LOX1 were also analyzed using quantitative realtime PCR (qPCR) in SALK_084889 and wild type Arabidopsis (Col, Columbia). Further, the comparison of drought and heat tolerance between Col and SALK_084889 were conducted by stress treatments. The present data indicate that in SALK_084889, the expression of DREB2A is not downregulated under normal growth conditions but can be affected only in roots under drought treatment, while LOX1 is significantly downregulated in both roots and shoots under all tested conditions. These data are original and have not been published elsewhere.
