Effects of salicylic acid pre-treatment on cadmium and/or UV-B stress in soybean seedlings

Biologia Plantarum (2013)

X. M. Li L. J.N. Bu Y. Y. Li L. H. Zhang

The present study examined the effect of salicylic acid (SA) pre-treatment on soybean seedlings exposed to cadmium and/or UV-B stress. Dry mass, pigment content, net photosynthetic rate (PN), stomatal conductance (gs), and transpiration rate (E) were decreased by the Cd and/or UV-B stress. SA alleviated the adverse effects of Cd and/or UV-B on growth, pigment content, PN, and gs, but did not mitigate the inhibitory effect of Cd/UV-B on E, or that of Cd on chlorophyll fluorescence parameters. Cd and/or UV-B induced oxidative stress and increased lipid peroxidation that was significantly decreased by SA pre-treatment. The Cd and/or UV-B increased superoxide dismutase (SOD) activity, decreased peroxidase (POD) activity, and catalase (CAT) activity was mostly unaltered. SA might act as one of the potential antioxidants as well as a stabilizer of membrane integrity to improve plant resistance to the Cd and/or UV-B stress.

A Systematic Investigation on Elaeocarpus Sylvestris Leaf Extract Capped Cuo Nanoparticles as Reducing Agent and Their Antioxidant Activity

G. Tejaswini L. J.D. Praveena Manga Raju Meher Baba G

Recently, the role of plant-based nanoparticles as sustainable catalysts has emerged as a new field in material science. As a result of their wide applicability, bio-designed nanocatalysts have dominated the present study. At this juncture, this study gives the rapid and systematic procedure for the formation of an aqueous Elaeocarpus Sylvestris plant leaf extract capped Copper Oxide nanoparticles (ESCuO NPs). A benign method has been established for the fabrication of ESCuO nanoparticles that which serves as an innocuous, renewable, and mild reducing agent. Vivid spectrochemical and optical experimental investigation supported the formation of the ESCuO particles. Based on TEM investigation, the produced ESCuO NPs had spherical shape and an average size of 53 nm. The phytochemicals were used as a reducing agent internally without the use of harmful chemicals or extremely high temperatures. The derived ESCuO NPs have been employed as a powerful catalyst to reduce 4-nitrophenol. Further, rate constants for different doses were calculated. The antioxidant efficiency of synthesised ESCuO NPs was determined. This study illustrates the way for cutting-edge synthesis of CuO NPs with numerous applications.

Effect of endophyte infection on chlorophyll a fluorescence in salinity stressed rice

Biologia Plantarum (2014)

X. M. Li Moyan Chen Jiankang Li L. J.N. Bu

We have earlier reported that the endophyte infection can enhance photosynthetic capacity and antioxidant enzyme activities in rice exposed to salinity stress. Now, the changes in primary photochemistry of photosystem (PS) II induced by Na2CO3 stress in endophyte-infected (E+) and endophyte-uninfected (E-) rice seedlings were studied using chlorophyll a fluorescence (OJIP-test). Performance indices (PIABS and PITotal) of E- and E+ rice seedlings revealed the inhibitory effects of Na2CO3 on PS II connectivity (occurrence of an L-band), oxygen evolving complex (occurrence of a K-band), and on the J step of the induction curves, associated with an inhibition of electron transport from plastoquinone A (QA) to plastoquinone B (QB). In E+ seedlings, Na2CO3 effects on L and K bands were much smaller, or even negligible, and also there was no pronounced effect on the J step. Furthermore, the OJIP parameters indicated that 20 mM Na2CO3 had a greater influence on the photosystem (PS) II electron transport chain than did the 10 mM Na2CO3, and that changes were greater in E- than in E+. Endophyte infection was therefore deemed to enhance the photosynthetic mechanism of Oryza sativa exposed to salinity stress.

Pretreatment with NaCl induces tolerance of rice seedlings to subsequent Cd or Cd + NaCl stress

Biologia Plantarum (2013)

L. J.Cuimei Yu X. M. Li Y. Y. Li L. L. Wang

Rice (Oryza sativa L.) seedlings were grown hydroponically in Hoagland's nutrient solution under controlled conditions to investigate the effects of NaCl pretreatment on their response to subsequent application of cadmium (Cd) alone and Cd + NaCl combination. The Cd stress caused growth retardation in all plants, significantly reduced pigment content, stomatal conductance (gs), and net photosynthetic rate (PN). Cd stress significantly increased malondialdehyde and proline content. Compared to Cd treatment alone, combination stress had more detrimental effects on the above parameters. However, the NaCl pretreatment was beneficial in improving the plant growth and plant tolerance to Cd alone or combination stress.
