In this experiment, maize plants were subjected to different concentrations (0, 50, 100, and 250 µM) of the herbicide 2, 4-dichlorophenoxyacetic acid (2, 4-D), with some groups primed abscisic (ABA) others not. Initial observations showed that after five days incubation, seedlings exposed highest concentration 4-D exhibited stunted growth a reduction in chlorophyll accumulation. Key parameters such as relative water content, rate, net assimilation rate decreased (by 25%, 39%, 35%...
Heat and Water Deficit Stress (WDS) tend to impede restrict the efficiency of photosynthesis, chlorophyll fluorescence, maximum photochemical quantum yield in plants based on their characteristic ability interfere with electron transport system photosystem II. Dissection pathway Photosystem II (PSII) under water deficit (HS) can be insightful gaining knowledge various attributes photosynthetic performance a plant. We attempt high-resolution dissection PSII studies fast fluorescence kinetics...
We revealed the functional characterization of C4-NADP-malic enzyme (NADP-ME), extracted and partially purified from maize (Zea mays L. cv. Kaveri 50). The leaf discs were previously activated under 1000–1200 µE m−2 s−1, incubated in bicarbonate (2.0 mM) solution, subjected to salt stress (100 mM NaCl). Initially, was evident accumulations proline, chlorophyll content, carbohydrate profile, Hill activity influencing C4 enzyme. Primarily, illuminated tissues, recorded a reduced trend through...
In this experiment, sub1A quantitative trait loci (sub1A QTL) of rice were evaluated for dehydration responses through different aspects cellular responses. Through variations exposure, seedlings recorded a significant increase in superoxide (O2.-) and hydrogen peroxide (H2O2), the former by 1.80 fold latter 2.10 fold. Nicotinamide adenine dinucleotide phosphate oxidase activity fairly correlated with lipid peroxidation (r = 1.96). Both 2,2-diphenyl-1-picrylhydrazyl (DPPH)...
The present investigation embodies with some distinct physiological responses of rice seedlings bearing sub1A allele when cultured under soil moisture deficit condition. In order to estimate the extent variation in cv. Swarna Sub1, few specific were recorded. Ongoing days (2, 4 and 8) water stress, mostly concerned regulation root growth through 1.24%, 4.10% 8.96% as compared control. When relative rate (RGR) biomass was considered, it recorded a significant down maximum by 27.27% over...
Two chili cultivars, i.e., cv. Bullet and Tejaswini, were evaluated on postharvest related ripening characteristics with varying durations under hydrogen peroxide, putrescine silver treatments. The reducing sugar was inversely to the maximum values at 7 days of ripening. Silver most regulatory in terms changing total carbohydrate content as compared hydrolysis sugar. Regarding pectin methylesterase activity, both chilies consistent, regardless number incubation. Still, significant...
• An aquatic fern has a well adaptability to herbicide toxicity. Cell wall modification with energy changes of bond is important for bio sorption. Nitrogen metabolism altered under Oxidative stress also established toxicity systematic herbicide.
In the present experiment, Zea mays L. was evaluated for its C4 modality through oxidative stress responses. Moreover, under variable concentrations (0, 50, 100µM) of hydrogen peroxide, impacts were and modulated with titanium dioxide nanoparticle (TiO2-NP). Plants scored elevated H2O2 superoxide (O2.-) maximum by 1.31 & 1.52-fold respectively over 0µM H2O2. TiO2-NP recovered those maximums 8.69 7.89% as compared to control plants. The effects moderated malondialdehyde carbonyl content...
This study analysed the rice genotype with sub1A quantitative trait loci that may interact ongoing exposure of dehydration. cv. Swarna Sub1 had more nutrients efficiency increased membrane permeability than Swarna. QTL its expression to water / osmotic deficit, however, indirectly impede oxidative stress under dehydration might help Sub1. At maximum 1.12 fold excess electrolyte leakages better Nicotinamide adenine dinucleotide phosphate-malic enzyme activity secure carbon dioxide exchange. A...
NADP –ME is the key enzyme for decarboxylation reactions in C4 CO2 concentration pathways. So, Amaranthus viridis has been evaluated with regards to photosynthetic NADP-malic its response under light and darkness. Illumination (1000–1200 µEm-2s-1) 40 minutes 2 mM bicarbonate (HCO3-) sensitivity increased activity by 1.97 & 3.77-fold over darkness 4.0 0.01 malate respectively. Limiting (0.01 mM) saturated (4.0 had significant changes activities. The different kinetic parameters indicated...
In the present study, sensitivity of two chemical elicitors: polyamine (PA) and salicylic (SA) acid were exercised for submergence in Swarna Sub1A rice variety. Under 5 days submergence, antioxidation responses more distinguished plants against control. Along with anti-oxidation modules, significant changes biomolecule loss registered through lipid protein oxidation by 1.91 1.46 -fold respectively. PA SA treated reliever to recover membrane potential. Total carbohydrate reducing sugars...
This work proposes NADP-ME activity as bio-indices for herbicidal sensitivity in Azolla pinnata R.Br. under 2,4-D toxicity. fronds were illuminated saturated photosynthetic flux and bicarbonate induction. There was significant variation the light dark conditions. increased more when varying concentrations of used up regulation enzyme especially illumination. evident modulation through activators (citrate succinate) inhibitors (pyruvate oxaloacetate) conditions at concentration. occurs same...
The paper reports the induced antioxidation property of Azolla pinnata R.Br. under elevated conditions herbicide 2,4-D. With respect to phenolic accumulation, plant registered varied in-vitro potentials. Total through phosphomolybdenum complex, DPPH (2,2-Diphenyl, 1-picryllydrazyl), and ABTS (2,2′-azino-bis 3-ethylbenzo-thiazoline-6-sulfonic acid) radical scavenging activities were most significant attributes this species. A gradual fall in complex suggested more involvement chelation 2,4-D,...
