Global food security is challenged by increasing levels of CO, O and temperature trough their impacts on production and grain quality of wheat, one of the major C crops and staple food across the world. The present study was conducted to assess the effects of elevated levels of CO (EC; 550 ppm) and tropospheric O (EO; 70 ppb) as well as of combined interactive treatment [EC X EO; ECO] on plant growth, yield and grain quality of two wheat cultivars (HD-2967 and C-306) grown during 2016-17 and 2017-18 using free air ozone and carbon dioxide enrichment (FAOCE) facility under field conditions. Individually, EC, increased leaf area index (LAI; 15.

Seed germination is crucial for the plant life cycle. We investigated the role of nitric oxide (NO) in two chickpea varieties that differ in germination capacity: Kabuli, which has a low rate of germination and germinates slowly, and Desi, which shows improved germination properties. Desi produced more NO than Kabuli and had lower respiratory rates.

Wheat cultivars are genetically crossed to improve end-use quality for traits as per demands of baking industry and broad consumer preferences. The processing and baking qualities of bread wheat are influenced by a variety of genetic make-ups, environmental factors and their interactions. Two wheat cultivars, WL711 and C306, derived recombinant inbred lines (RILs) with a population of 206, were used for phenotyping of quality-related traits.

Wheat is a major food crop and an important component of human diet throughout the world. There are two major types of cultivated wheat; one is tetraploid durum (pasta) wheat and another one is hexaploid bread wheat. Wheat grain is the reservoir of two major dietary components - carbohydrate and protein, which get accumulated during seed maturation and directly affects yield and quality.

Imbalanced potassium (K) fertilization in agricultural fields has led to considerable negative impacts and remains to be the foremost challenge for maize production in India-Gangetic region. Plant growth-promoting rhizobacteria, particularly potassium solubilizing rhizobacteria (KSR), could serve as inoculants and a promising strategy for enhancement of plant absorption of K hence reducing dependency on chemical fertilizers. Maize seeds were microbiolized for 30 min with KSR suspensions.

The frequently used chemical control method to manage Rhipicephalus microplus is limited by the emergence of resistance populations. Understanding of resistance mechanisms is essential to develop strategy for sustainable management. The present study was focused on working out the molecular mechanisms of resistance against synthetic pyrethroids (SPs) and organophosphates (OPs) in field isolates of R.

Rice, a staple food crop, is often subjected to drought and salinity stresses thereby limiting its yield potential. Since there is a cross talk between these abiotic stresses, identification of common and/or overlapping regulatory elements is pivotal for generating rice cultivars that showed tolerance towards them. Analysis of the gene interaction network (GIN) facilitates identifying the role of individual genes and their interactions with others that constitute important molecular determinants in sensing and signaling cascade governing drought and/or salinity stresses.

Department of Pesticides and Agrochemicals, School of Chemical Sciences, North Maharashtra University, Jalgaon, Maharashtra, 425 001, India.

In designing of novel insect growth regulators (IGRs), biologically occurring carvacrol has been structurally modified to thiadiazole and oxadiazole moieties. Two series of carvacrol analogs containing 1,3,4-thiadiazole (VIIIa-e) and 1,3,4-oxadiazole (IXa-e) derivatives are designed and synthesized. Their structures are confirmed by FT-IR, [Formula: see text] NMR, [Formula: see text]C NMR and LC-MS.

Cyanobacteria are one of the ancient bacterial species occupying a variety of habitats with diverse metabolic preferences. RNA regulators like riboswitches play significant role in controlling the gene expression in prokaryotes. The taxonomic distribution of riboswitches suggests that they might be one of the oldest mechanisms of gene control system.

Internal oxygen concentrations vary in different tissues depending on tissue size, developmental stage, and their location. Respiratory rate of tissue also determines internal oxygen levels. For studying various signaling pathways it is essential to establish a correlation between respiration and internal oxygen.

Persistent or chronic infection with the hepatitis B virus (HBV) represents one of the most common viral diseases in humans. The hepatitis B virus deploys the hepatitis B virus X protein (HBx) as a suppressor of host defenses consisting of RNAi-based silencing of viral genes. Because of its critical role in countering host defenses, HBx represents an attractive target for antiviral drugs.

Cardamom is a popular spice that has been commonly used in cuisines for flavor since ancient times. It has copious health benefits such as improving digestion, stimulating metabolism, and exhibits antioxidant and anti-inflammatory effects. The current study investigated the effect of cardamom on hemodynamic, biochemical, histopathological and ultrastructural changes in isoproterenol (ISO)-induced myocardial infarction.

Understanding and quantification of geochemical processes in vadose zone of sewage-effluent-irrigated soils are helpful in predicting the transference of metals and other ions to food chain and groundwater. Hence, an attempt has been made to simulate various geochemical processes occurring in the flow path of infiltrating sewage water down the vadose zone with the help of Net Geochemical Reaction Along the Flow Path (NETPATH). This study area was located in Western Delhi, India, where sewage effluents originating from Keshopur Sewage Treatment plant have been used for irrigation since 1979.

Agricultural lands in the peri-urban area of New Delhi have been irrigated with treated wastewater from the Keshopur Effluent Irrigation Scheme (KEIS) since 1979. An attempt has been made to study the influence of wastewater irrigation on pH, electrical conductivity, organic carbon, and dynamics of heavy metal concentrations in vadose zone under KEIS. For this study, agricultural lands which have been receiving the sewage irrigation for 20, 10, and 5 years were selected.

Physicochemical properties of citric acid treated sweet potato starches were investigated in the present study. Sweet potato starch was hydrolyzed using citric acid with different concentrations (1 and 5%) and time periods (1 and 11 h) at 45 °C and was denoted as citric acid treated starch (CTS1 to CTS4) based on their experimental conditions. The recovery yield of acid treated starches was above 85%.

We investigated viral gene suppression in an infected tomato, by transforming it with RNA inhibition (RNAi) constructs derived from same viral gene. To develop RNAi constructs, conserved sequences ranging from 21 to 200 nt of the viral target AC4 gene of various viruses causing the tomato leaf curl disease were chosen. The double-stranded (ds)RNA producing constructs carry the sense and antisense portions of these sequences and are separated by different introns behind a constitutive promoter.
