BACKGROUND Cadmium (Cd) is a major heavy metal pollutant which is highly toxic to plants and animals. Vast agricultural areas worldwide are contaminated with Cd. Plants take up Cd and through the food chain it reaches humans and causes toxicity. It is ideal to develop plants tolerant to Cd, without enhanced accumulation in the edible parts for human consumption. Glutathione transferases (GST) a...

Mercury-specific diffusive gradient in thin films (DGTs) were used in laboratory microcosms as a biomonitoring tool to assess the lability of mercury (Hg) total and monomethylmercury Hg (MeHg), and to develop a relationship between chemical lability and bioavailability in estuarine sediments. Time-series deployment of DGTs in sediments showed that sediment-bound MeHg is more labile than sedimen...

Sweet corn (Zea mays L.) cultivars carrying the sh2 mutation show poor seed vigor under stressful field conditions, requiring higher seeding rates to ensure stand establishment. The effects of sodium hypochlorite seed disinfestation, solid matrix priming (SMP), and seed-coating with Gliocladium virens Miller, Giddens & Foster to enhance emergence of sh2 sweet corn in controlled-environment cold...

Aim This study examines changes in avian community composition associated with the decline and loss of eastern hemlock [Tsuga canadensis (L.) Carr.] resulting from chronic hemlock woolly adelgid (HWA; Adelges tsugae Annand) infestations. Location The study was conducted in a 4900-km study region extending from Long Island Sound northward to the southern border of Massachusetts and including the...

Chemically managed plants impose environmental risks to humans and environment. Using biological approaches control plant diseases is a more effective environment friendly alternative. The approach disease refers controlling by using organisms like fungi, bacteria viruses. This can be done introduction or utilization of resident antagonistic living organisms. Biological achieved through differe...
