“…But, further increase in ZnO nanoparticles dose does not support further increment of chlorophyll level. Similar increase in chlorophyll level was also reported by Prasad et al (2012) by application of ZnO nanoparticles. They reported that the chlorophyll content of the 1000 ppm ZnO nanoparticle-treated plant increased up to 1.97 mg/ g f.w which was more than that of the untreated plant.…”

“…They also reported that plant growth reached up to 15.4 cm when the seeds were treated with 1000 ppm ZnO nanoparticle. Such increment in plant growth is probably due to production of higher concentration of auxin under the influence of ZnO nanoparticles (Prasad et al 2012). Previous study also highlighted on retardation in early growth of chickpea seedlings at high dose of ZnO nanoparticles and low dose of ZnO nanoparticles which is sufficient to achieve positive response (Mahajan et al 2011;Burman et al 2013).…”

“…The effect of ZnO and TiO 2 nanoparticles on root and shoot length of Cicer arietinum is presented in reported by Prasad et al (2012). They reported that with increasing concentration of ZnO from 400 to 1000 mg/L, the height of the plant significantly increased with respect to control.…”

“…). Moreover, this metal is extremely essential for plant's enzyme system as it acts as cofactors, metal components and other regulatory factors of many enzymes (Prasad et al 2012). So far as plant nutrients are concerned, in India, amongst the yield-enhancing micronutrients, Zn comes in the fourth position just after nitrogen (N), phosphorous (P) and potassium (K), whereas in plants, titanium (Ti) is a non-available element in natural conditions.…”

With the development of nanotechnology, metal oxide nanoparticles have been applied in many industries, increasing their potential exposure level in the environment, yet their environmental safety remains poorly evaluated. Present work demonstrated the effects of ZnO and TiO 2 nanoparticles on the germination, morphoanatomical attributes and biochemistry of Cicer arietinum. The nanoparticles are used in three doses, i.e., 100, 500 and 1000 ppm along with control and each dose has three replicates. Results demonstrated that ZnO nanoparticles did not aid in the germination of seed, whereas TiO 2 nanoparticles showed positive impact on germination at 48-h observation. But at 72-h observation both the nanoparticle-treated and control seeds showed 100% germination. Morphological parameters revealed that ZnO nanoparticles have drastic negative impact on both root and shoot length, root and shoot fresh and dry biomass. On the other hand, the status of chlorophyll is almost opposite, i.e., ZnO nanoparticle-treated plants showed higher pigment content than TiO 2 nanoparticle-treated plants. From the statistical point of view, it is revealed that ZnO nanoparticle-treated plant showed significantly different results than that of TiO 2 nanoparticle-treated plants in Chl 'a' (p \ 0.001), Chl 'b' (p \ 0.001), total Chl (p \ 0.001) and carotenoid (p \ 0.001) content. Therefore, from these observations it can be concluded that ZnO nanoparticles showed positive effect on plant pigment content.Transverse sections of root clearly revealed the formation of vascular bundle, and parenchyma tissue is hampered in all the ZnO nanoparticle-treated plants. However, wellformed vascular bundles and other tissue systems are clearly visible for TiO 2 nanoparticle-treated roots. This work shows a combination of both positive and negative effects of ZnO and TiO 2 nanoparticles on a dicot plant. Present observation is very much important to understand the morphological, biochemical and anatomical alteration of plant system under the influence of ZnO and TiO 2 nanoparticles. This will help to utilize the nanoparticles in a managed way where nanoparticles with harmful effect on biological systems can be used in such a way to reduce their exposure to environment, and on the other hand, nanoparticles showing positive effect on biological systems may be used as growth enhancers or biofertilizers. Moreover, these results further strengthen our understanding of environmental safety information with respect to metal oxide nanoparticle.

Combating antibiotic resistance requires discovery of novel antimicrobials effective against resistant bacteria. Herein, we present for the first time, pGLO plasmid transformed Escherichia coli HB 101 K 12 as novel model for screening of nanomaterial-based antimicrobial agents against b-lactamase resistance. E. coli HB 101 was transformed by pGLO plasmid in the presence of calcium chloride (50 mM; pH 6.1) aided by heat shock (0-42-0°C). The transformed bacteria were grown on Luria-Bertani agar containing ampicillin (amp) and arabinose (ara). The transformed culture was able to grow in the presence of ampicillin and also exhibited fluorescence under UV light. Both untransformed and transformed bacteria were used for screening citrate-mediated nanosilver (CNS), aloin-mediated nanosilver (ANS), 11-a-ketoboswellic acid (AKBA)-mediated nanosilver (BNS); nanozinc oxide, nanomanganese oxide (NMO) and phytochemicals such as aloin and AKBA. Minimum inhibitory concentrations (MIC) were obtained by microplate method using q-iodo nitro tetrazolium indicator. All the compounds were effective against transformed bacteria except NMO and AKBA. Transformed bacteria exhibited reverse cross resistance against aloin. ANS showed the highest antibacterial activity with a MIC of 0.32 ppm followed by BNS (10.32 ppm), CNS (20.64 ppm) and NZO (34.83 ppm). Thus, pGLO plasmid can be used to induce resistance against b-lactam antibiotics and the model can be used for rapid screening of new antibacterial agents effective against resistant bacteria.
