Research ArticleOpen accessIn the abstractLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,480 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResponse of Different Agrobacterium Rhizogenes Strains for in vitro Hairy Root Induction and Accumulation of Rosmarinic Acid Production in Agastache RugosaWoo Tae Park, Thanislas Bastin Baskar, Sun Kyung Yeo et al.In this study a total of seven different Agrobacterium rhizogenes strains were evaluated for their ability to transform the plant Agastache rugosa and to produce the secondary metabolite rosmarinic acid. All the strains of A. rhizogenes i.e., 13333, 15834, A4, LBA9402, R1000, R1200 and R1601 strains tested here in this study, were able to induce hairy root formation in leaf … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 3 Sep 2017 · 7,866 accessesView PDF Cite
