Flavonoid derived components have been studied for their therapeutic properties. Apigenin has shown remarkable anti-oxidant and anti-inflammatory features; however having a reliable source of apigenin is necessary. In this study the amount of apigenin in flowers, roots, leaf and stems of three varieties of Cosmos bipinnatus: Dazzler, Xanthos and Sensation pinkie and also in transgenic root cult...

The cultivation of genetically modified plants (GMP) has raised concerns regarding the plants' ecological safety. A greenhouse experiment was conducted to assess the impact of five seasons of continuous Bt (Bacillus thuringiensis) maize cultivation on the colonisation and community structure of the non-target organisms arbuscular mycorrhizal fungi (AMF) in the maize roots, bulk soils and rhizos...

NAC genes contribute to enhance survivability of plants under conditions of environmental stress and in secondary growth of the plants, thereby building biomass. Thus, genetic transformation of plants using NAC genes provides a possibility to tailor biofuel plants. Over-expression studies have indicated that NAC family genes can provide tolerance to various biotic and abiotic stresses, either b...

We propose the use of the cubic transformation for public-key applications and digital signatures. Transformations modulo a prime p or a composite n = pq, where p and q are primes, are used in such a fashion that each transformed value has only 3 roots that makes it a more efficient transformation than the squaring transformation of Rabin, which has 4 roots. Such a transformation, together with...

Lactuca serriola L. is a herbaceous species, used for human nutrition and medicinal purposes. The high antioxidant capacity of L. serriola indicates the possibility of enhancing its edible and health potential by increasing the flavonoid and phenolic contents. The present study aimed at enhancing the production of phenolics and flavonoids by hairy root cultures in Lactuca serriola transformed w...

Environmental pollution especially with heavy metals poses serious problem on product synthesis of medicinal plants cultivated in the field. Accordingly, the purpose of this study was to assess in vitro effects of cadmium as abiotic elicitor on phytoestrogens production by Psoralea corylifolia hairy roots. Transformed hairy roots were developed by genetic transformation using Agrobacterium rhiz...

The roots and rhizomes of Valeriana (Valerianaofficinalis L.) are rich with valuable metabolites such as valerenic acid and valepotriates are used as mild sedatives. The aim of the present study was to investigatethe effect of four levels of calcium and potassium compounds (half, full, 2 and 4-fold) of normal Murashige and Skoog (MS) media including KI and CaCl2on ValerianaofficinalisL. hairy r...
