Phenotypic and genotypic diversity of root nodule bacteria from wild Lathyrus and Vicia species in Gaziantep, Turkey.

This study identified the phenotypic and genotypic characteristics of the bacteria that nodulate wild Lathyrus and Vicia species natural distribution in the Gaziantep province of Turkey. Principle component analysis of phenotypic features revealed that rhizobial isolates were highly resistant to stress factors such as high salt, pH and temperature. They were found to be highly sensitive to the concentrations (mg/mL) of the antibiotics neomycin 10, kanamycin, and tetracycline 5, as well as the heavy metals Ni 10, and Cu 10, and 5.

Trends in Phenolic Profiles of from Different Geographical Gradients.

The traditional widely used raw material of is currently mainly derived from wild populations, leading to diversification and uncertainty in its quality. The aim of the study was to determine the accumulation differences of phenolic compounds between geographically distant populations of from northern and southern gradients. Plant material was collected from Gaziantep and Nevşehir provinces in Turkey and from wild populations in Lithuania.

Distribution of Phenolic Compounds and Antioxidant Activity in Plant Parts and Populations of Seven Underutilized Wild Species.

Evaluation of phytochemical composition of underutilized species provides the primary selection of germplasms with the desired quality of raw material for their further applications. The aim of the study was to evaluate the comprehensive distribution patterns of phenolic compounds in seven wild spp. and their plant parts, and to assess their antioxidant activity.

Diversity of rhizobial and non-rhizobial bacteria nodulating wild ancestors of grain legume crop plants.

Chickpeas, lentils, and peas are the oldest grain legume species that spread to other regions after their first domestication in Fertile Crescent, and they could reveal the rhizobial evolution in relation to the microsymbionts of wild species in this region. This study investigated the phenotypic and genotypic diversity of the nodule-forming rhizobial bacteria recovered from Pisum sativum subsp., Cicer pinnatifidum, and Lens culinaris subsp.

Secondary metabolites of seven Hypericum species growing in Turkey.

Context The genus Hypericum (Hypericaceae) has attracted remarkable scientific interest as its members have yielded many bioactive compounds. Objective The current study presents investigations on the accumulation of hypericin, pseudohypericin, hyperforin, adhyperforin, chlorogenic acid, neochlorogenic acid, caffeic acid, 2,4-dihydroxybenzoic acid, 13,118-biapigenin, hyperoside, isoquercitrin, quercitrin, quercetin, avicularin, rutin, (+)-catechin and (-)-epicatechin in seven Hypericum (Hypericaceae) species growing wild in Turkey, namely, H. aviculariifolium Jaup.
