“…decreased at optimum concentrations of nanoparticles. Hassan et al (2020) described that when higher application of Ag NPs treated plants gave higher prolein content as compared to control and our findings are co relate with it i.e higher Ag/ZnO nanoparticle produce high proline content.Salama et al (2012) reported that high protein content was achieved at higher concentration of AgNPs concentration as compared to control in Zea mays and Phaseolus vulgaris and our findings are co related with this study as application of Ag/ZnO NPs at optimum concentration (300ppm), decrease protein contet however by increasing concentration protein content got increased Mahawar et al (2018). explained that on cyanobacterium Calothrix elenkinii, defense against ROS.…”

Peach (Prunus persica L.) be a part of family Rosacea, although Aaru is its local name. Pakistan ranked 25th in peach production. In Pakistan, peach is a prime stone fruit after plum. It is summer fruit but can be used in winter season after drying its fruit. It also contains medicinal properties because it carries various phenolic compounds in fruit. Termites are one of the most important insect that damage the peach tree and due to their attack tree should be hollowed, leaves become wilt and ultimately becomes in the form of plant death. Termites attack on plants can be control by a unique innovative technique which is nanotechnology. Nanotechnology is the 21st century science executes output of various nanoparticles possessing range amid 1 to 100 nm. Among these, Ag/ZnO nanoparticles are very important due to raised surface area to volume ratio and catalytic efficiency. Bimetallic nanoparticles may increase water uptake, nutrient use efficiency, hence may improve plant growth and their yield by changing physio-morphic and biochemical attributes. Green bimetallic Ag/ZnO nanoparticles will be synthesized from salts reduced by Moringaoleifera Lam. Ag/ZnO nanoparticles will be characterized by UV-Visible Spectroscopy, SEM, FTIR and EDX. Nanocomposite Ag/ZnO with various concentrations i.e 100ppm, 200ppm, 300ppm, 400ppm, 500ppmand have two control (T + no treatment and T- 500ppm Ag/ZnO salt). Effect will be analyzed for physiological (membrane stability index, chlorophyll content, relative water content), biochemical (SOD, POD, catalase, proline content, protein content, sugar content). All the obtained data will be analyzed through ANOVA by using SPSS 16.1 program.

This study was undertaken to bridge the knowledge gap pertaining to cyanobacteria’s response to pretreatment. The result elucidates the synergistic effect of pretreatment toxicity in cyanobacterium Anabaena PCC7120 on morphological and biochemical attributes. Chemical (salt) and physical (heat) stress-pretreated cells exhibited significant and reproducible changes in terms of growth pattern, morphology, pigments, lipid peroxidation, and antioxidant activity. Salinity pretreatment showed more than a five-fold decrease in the phycocyanin content but a six-fold and five-fold increase in carotenoid, lipid peroxidation (MDA content), and antioxidant activity (SOD and CAT) at 1 h and on 3rd day of treatment, respectively, giving the impression of stress-induced free radicals that are scavenged by antioxidants when compared to heat shock pretreatment. Furthermore, quantitative analysis of transcript (qRT-PCR) for FeSOD and MnSOD displayed a 3.6- and 1.8-fold increase in salt-pretreated (S-H) samples. The upregulation of transcript corresponding to salt pretreatment suggests a toxic role of salinity in synergizing heat shock. However, heat pretreatment suggests a protective role in mitigating salt toxicity. It could be inferred that pretreatment enhances the deleterious effect. However, it further showed that salinity (chemical stress) augments the damaging effect of heat shock (physical stress) more profoundly than physical stress on chemical stress possibly by modulating redox balance via activation of antioxidant responses. Our study reveals that upon pretreatment of heat, the negative effect of salt can be mitigated in filamentous cyanobacteria, thus providing a foundation for improved cyanobacterial tolerance to salt stress.
