No full textNot AvailableIn the recent survey, Japanese encephalitis (JE) is one of the most common mosquito-borne diseases, accounting for ∼30% of fatalities. The outbreaks of the JE virus (JEV) suggests that exhaustive study is essential for the prevention and management of the disease. The disease mainly spreads in humans and pigs by the vector: mosquito; as this is a major concern, this study had employed various bioinformatics tools to investigate the codon usage bias, evolutionary inference and selection pressure analysis of the Japanese encephalitis virus disease. The results indicated that the JE virus was biased and natural selection was the main factor shaping the codon usage that was determined and confirmed with the Nc, neutrality, PR2 plots and correlation analysis. The evolutionary analysis revealed that the virus had a substitution rate of 1.54 × 10-4 substitution/site/year and the tMRCA was found to be in 1723. The transmission of the virus in the map found transmissions mostly from China and transmitted across Asia and Africa. The selection pressure analysis employed three methods which had 969th codon site as diversifying site and had many purifying sites that shows the virus had evolved rapidly. The inferences from this study would aid people to employ this methodology on various diseases and also perform insilico studies in the field of vaccinology and immunoinformatics.Not Availabl

Plant growth-promoting rhizobacteria (PGPRs) have been found to suppress the adverse effect of disease on plants. In the present investigation, an attempt has been made to evaluate the effect of PGPR strains isolated from the rhizosphere soil of medicinal plants on rice under stress conditions. We isolated 158 morphologically distinct bacterial strains and tested them against R. solani under invitro conditions and found 52 promising strains with more than 50% antifungal activity. These strains were examined for their physiological and biochemical characteristics and further confirmed with 16S rDNA gene-specific markers. Strains that inflicted > 80% inhibition during in-vitro studies were selected for pot and field experiments. The results indicated that Bacillus velezensis, B. megaterium, and B. toyonensis registered significantly higher plant growth-promoting activities with enhanced germination, seedling vigor, and dry weight. In addition, applying these PGP strains exhibits the lowest disease incidence, relative lesion length, delayed sclerotia formation, and recorded maximum grain yield per pot. The field study further confirmed that B. toyonensis provided significant disease suppression with least disease incidence (PDI: 17.37 and 12.88), relative lesion length percent (27.71and12.88), area under disease progress curve (382.98 and 286.25) value (AUDPC), and highest grain yield (63.00 and 48 t ha− 1) in Tapaswini and CR Dhan 1014 varieties, respectively, followed by B. megaterium and B. velezensis. The PGPR-treated plants also showed enhanced activities of defense enzymes like polyphenol oxidase, superoxide dismutase, and catalase showing induced systemic resistance (ISR). Thus, these three PGPR strains
from medicinal plants enhanced the tolerance of rice to ShB disease with improved crop growth. Integrating these PGPR in seed treatment, seedling root dip and foliar application will improve the rice yield and farmers’ livelihood.Not Availabl

No full textNot AvailablePlants require zinc (Zn) as an essential micronutrient since Zn plays important roles in metabolism. Arsenic (As) is a toxic metalloid whose accumulation in plants hampers growth of plants. Rice crops are grown under flooded conditions that make them vulnerable to double jeopardy of Zn deficiency and As stress. The goal of this study was to observe the effect of ZnO nanoparticle (NP) and ZnO-NP + biochar on As and Zn accumulation in and growth of rice plants grown under flooded conditions. The study area was Chausa block in Buxar district, Bihar, India. Rice crops were treated with 80 mg L−1 of ZnO-NP and biochar was added to soil at rate of 10 t ha−1. ZnO-NP were sprayed at heading and jointing stage of crop development. The results showed a significant increase in rice growth and yield by 14–26% and 30–33% respectively along with total chlorophyll content in ZnO-NP and ZnO-NP + biochar as compared to control. The level of electrolytic leakage and malondialdihyde (MDA) content was observed to decrease by 48–62% and 14–55%, respectively in treated plants as compared to control. Further, As accumulation was reduced in rice grains by >90% while Zn accumulation was increased by >50% in ZnO-NP and ZnO-NP + biochar treatments than that in control. The enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), guaiacol peroxidase (GPX), and catalase (CAT) showed higher activity in treated crop plants than in control plants. The findings confirm that ZnO-NP and their combined use with biochar in flooded agricultural soil can help to improve growth, yield and reduce As accumulation in rice plants.Not Availabl
