Silver nanoparticles (AgNPs) are widely used in commercial products, and there are growing concerns about their impact on the environment. Information about the molecular interaction of AgNPs with plants is lacking. To increase our understanding of the mechanisms involved in plant responses to AgNPs and to differentiate between particle specific and ionic silver effects we determined the morpho...

As a cytosolic transcription factor, the aryl hydrocarbon (Ah) receptor is involved in several patho- physiological events leading to immunosuppression and cancer; hence antagonists of the Ah receptor may possess chemoprevention properties. It is known to modulate carcinogen-metabolising enzymes, for instance the CYP1 family of cytochromes P450 and quinone reductase, both important in the biotr...

Hypergravity is able to stimulate at a cellular level both the lignin formation and the peroxidase enzyme action in plants. Centrifuges have proven to be one of the most important tools for researchers for simulating such conditions. This paper presents a new design for a centrifuge simulating hypergravity used for plant experiments. It represents a more robust and completely redesigned equipme...

Variation in somatic and gametic chromosome numbers in Ribes nipuw (Vaarama 1949) and Eruca sativa (Rajan et al., 1950) has been attributed to the formation of accessory spindle and subsequent "elimination of clzrolnosoines e n bloc". In sugarcane, Parthasarathy (1951)~ after exa~nining the slides of megasporogenesis in Co. 421 prepared by Subrainaniam (1946), concluded that the mechanism of el...

The structurally unique glucosinolate (GSL), 4-(cystein-S-yl)butyl GSL, was identified in the leaves of hydroponically-grown rocket salad (Eruca sativa Mill.). Its electrospray ionization mass spectrometry (ESI-MS)/MS spectrum indicated that this unusual GSL had a molecular weight of 414 as a desulfo (DS)-GSL, and a molecular formula of C(14)H(25)N(2)O(8)S(2) based on its negative ion matrix-as...

Selenium (Se) is an essential micronutrient for humans, but most foods are Se deficient, mainly because of its low content in the soil. A Se-deficient diet results increased susceptibility to cardiovascular disease, cancer, and hyperthyroidism. Agronomic biofortification a good alternative increase food. This study investigated effect on growth, yield, rocket. Plants were grown hydroponic syste...
