{ "DOI": "10.1515/znc-2015-0226", "abstract": "Recent studies indicate an extremely high level of tolerance to boron (B) toxicity in Puccinellia distans (Jacq.) Parl. but the mechanistic basis is not known. Puccinellia distans was exposed to B concentrations of up to 1000 mg B L-1 and root B uptake, growth parameters, B and N contents, H2O2 accumulation and center dot OH-scavenging activity were measured. Antioxidant enzyme activities including superoxide dismutase (SOD), ascorbate peroxidase, catalase, peroxidase and glutathione reductase, and lipid peroxidation products were determined. B appears to be actively excluded from roots. Excess B supply caused structural deformations in roots and leaves, H2O2 accumulation and simultaneous up-regulation of the antioxidative system, which prevented lipid peroxidation even at the highest B concentrations. Thus, P. distans has an efficient root B-exclusion capability and, in addition, B tolerance in shoots is achieved by a well-regulated antioxidant defense system.", "author": [ { "family": "Hamurcu", "given": " Mehmet" }, { "family": "Hakki", "given": " Erdogan E." }, { "family": "Sert", "given": " Tijen Demiral" }, { "family": "Ozdemir", "given": " Canan" }, { "family": "Minareci", "given": " Ersin" }, { "family": "Avsaroglu", "given": " Zuhal Z." }, { "family": "Gezgin", "given": " Sait" }, { "family": "Kayis", "given": " Seyit Ali" }, { "family": "Bell", "given": " Richard W." } ], "container_title": "ZEITSCHRIFT FUR NATURFORSCHUNG SECTION C-A JOURNAL OF BIOSCIENCES", "id": "59663", "issue": "7-8", "issued": { "date-parts": [ [ 2016, 1, 1 ] ] }, "page": "273-285", "title": "Extremely high boron tolerance in Puccinellia distans (Jacq.)
