    Extremely high boron tolerance in Puccinellia distans (Jacq.) Parl. related to root boron exclusion and a well-regulated antioxidant system
    (WALTER DE GRUYTER GMBH, 2016) Hamurcu, Mehmet; Hakki, Erdogan E.; Sert, Tijen Demiral; Ozdemir, Canan; Minareci, Ersin; Avsaroglu, Zuhal Z.; Gezgin, Sait
    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.

    A New Record for the Flora of Turkey: Crambe hispanica L. (Brasssicaceae)
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2009) Yildiztugay, Evren; Kucukoduk, Mustafa; Ozel, Musa; Ozdemir, Canan
    Crambe hispanica L., collected during the floristic study of Anamurium Antique City (Anamur, Mersin province), is reported as a new record for the flora of Turkey. The new record is described and illustrated, and a distribution map is presented.
