TiO2 nanoparticle biosynthesis and its physiological effect on mung bean (Vigna radiata L.)☆

چکیده
TiO2 nanoparticle (NPs) biosynthesis is a low cost, ecofriendly approach developed using the fungi Aspergillus flavus TFR 7. To determine whether TiO2 NPs is suitable for nutrient, we conducted a two part study; biosynthesis of TiO2 NP and evaluates their influence on mung bean. The characterized TiO2 NPs were foliar sprayed at 10 mgL-1 concentration on the leaves of 14 days old mung bean plants. A significant improvement was observed in shoot length (17.02%), root length (49.6%), root area (43%), root nodule (67.5%), chlorophyll content (46.4%) and total soluble leaf protein (94%) as a result of TiO2 NPs application. In the rhizosphere microbial population increased by 21.4-48.1% and activity of acid phosphatase (67.3%), alkaline phosphatase (72%), phytase (64%) and dehydrogenase (108.7%) enzyme was observed over control in six weeks old plants owing to application of TiO2 NPs. A possible mechanism has also been hypothesized for TiO2 NPs biosynthesis.

Arsenic Induced Changes in Growth and Physiological Responses in Vigna radiata Seedling: Effect of Curcumin Interaction
Arsenic is a great hazard to the environment since it is a major source of soil and water contamination leading to phytotoxicity. Arsenic caused reduction in seed germination and growth of plants including mung bean (Vigna radiata) causing loss of crop productivity. This investigation evaluates effect of arsenic toxicity in mung bean with an attempt to ameliorate it by the application of curcum...

Rhizobium inoculation has successfully been used for improving growth and yield of legume crops in different parts of the world. L-Tryptophan (L-TRP) application may further improve its effectiveness due to substrate-dependent inoculum-derived auxins in the rhizosphere. Rhizobium phaseoli strains were isolated using dilution plate technique from the mung bean nodules. Auxin biosynthesis by thes...
متن کاملThe Effect of Different Soil Amendments on Growth of Mung bean (Vigna Radiata L.) in Coal Mine Overburden Dumps
The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...

Phosphatidylglycerophosphate synthase (sn-glycerol-3-phosphate:CDP-diacylglycerol phosphatidyltransferase) and phosphatidylglycerophosphate phosphatase were characterized in mung bean (Vigna radiata L.) mitochondria. The synthase has a rather broad pH optimum between 7 and 9, whereas the phosphatase has one of about 7. Both enzymic activities are stimulated by Triton X-100 and require divalent ...
متن کاملMung Bean (Vigna radiata) Seedlings'
Two forms of Fd-NADP+ oxidoreductase (FNR) isoproteins have been purified and characterized from the first foliage leaves of 5d-old mung bean (Vigna radiata). They could be separated by either Mono Q HR 515 or ferredoxin (Fd)-Sepharose 48 affinity columns. Based on immunoblot analysis and N-terminal amino acid sequences, one form resembles the FNR purified from photosynthetic tissues of higher ...
