“…High copper stress increased MDA content both in wild-type and transgenic plants (Fig. 4A), similar to what has been found in other species (35,36). Less MDA accumulation in transgenic plants suggested that lipid peroxidation developed less in transgenic plants on high copper stress.…”

Copper is essential but toxic in excess for aerobic organisms. Yeast transcription factor ACE1 functions as a sensor for copper and an inducer for the transcription of CUP1. In addition, ACE1 can activate the transcription of superoxide dismutase gene (sod1) in response to copper. In this study, we introduced the yeast ACE1 into Arabidopsis and analyzed its function in plant. Under high copper stress, the transgenic plants over-expressing ACE1 showed higher survival rate than the wild-type. We also found that over-expression of ACE1 in Arabidopsis increased the activities of SOD and POD, which were beneficial to the cell in copper buffering. Excess copper would suppress the expression of chlorophyll biosynthetic genes in Arabidopsis, RT-PCR analysis revealed that over-expression of

“…Total RNA from leaves of plants transformed with pYK4147 was isolated. The internal standard gene and PCR reaction were the same as that used by Zhu et al (2008). A 209-bp fragment of the MdMYB6 gene was amplified using two specific primers (MdMYB6Z1: 5 0 -AAC,AGC,AGT,AAC,AGC,GAG,AAG, AAC,GAC,C-3 0 ; MdMYB6F1: 5 0 -TCC,TTC,CTT,ATC,A TC,CCT,TGC,ATC,ACC-3 0 ).…”

The R2R3-Myb proteins comprise a large family of plant transcription factors that regulate the expression of multiple drought-responsive and coldresponsive genes by binding special cis-elements at the promoter. There have been previous studies in transgenic plant over-expression of the myb protein. In this article, we analyzed the function of MdMYB6, an R2R3-type Myb transcription factor from apples (Malus 9 domestica), in transgenic Arabidopsis plants. In contrast to wild type plants, these transgenic lines accumulated less anthocyanin. Equimolar concentrations of sorbitol did not alter the anthocyanin accumulation. Real-time polymerase chain reaction (PCR) indicated that MdMYB6 over-expression suppressed enzymes involved in anthocyanin biosynthesis and some Arabidopsis basic helix-loop-helix (bHLH) genes. The MdMYB6 transcription faction may be an important repressor of anthocyanin biosynthesis in plants.

“…Pro is an indicator of oxidative stress. It accumulates in plant tissues when exposed to many environmental factors (Zhu et al, 2008) as well as has chelating and antioxidant properties, protecting enzymes from the denaturing effects of ROS. By capturing singlet oxygen, it protects CAT, POX, and polyphenol oxidase, among others (Verbruggen and Hermans 2008).…”

Plants are constantly exposed to a variety of stressors during their lives. One of such stressors is contamination of the environment with heavy metals. Lead is one of highly toxic metals and it significantly inhibits normal plant growth. The study aimed at assessing the degree of relieving the stress caused by 1 mM Pb(NO 3 ) 2 via different biologically active substances (AsA, GSH, PP, α-Toc, SA) on the basis of the measurement of morphological (root length, coleoptile length, fresh weight), biochemical (Pro, MDA, CAT, POX) and physiological (Chl a+b, Car) traits in 10-day leaves of spring barley of the cultivar Eunova under laboratory conditions. Pb-stress reduced the fresh weight, root length and coleoptiles of the barley tested. Lead increased lipid peroxidation and Pro content, enhanced CAT and POX activity, and significantly suppressed the photosynthetic pigments content. Among the substances used in the experiment, PP, α-Toc and GSH generally relieved the toxic effect of lead to the barley seedlings to the greatest degree.
