  • Multifaceted Strategies Used by Root-Knot Nematodes to Parasitize Plants-A Review
  • Abstract Root-knot nematodes being omnipresent in agricultural and horticultural soils are tallied among the most important economic pathogens around the world. For successful parasitism, these nematodes use various strategies to control and manipulate the host plant’s cell machinery. These strategies include the molecular mimicry of some host genes by some nematode secreted effector proteins, secretion of cell wall digesting enzymes and other effector proteins that are responsible for the suppression of defence by the host plant. All these secretions which are released through the stylet, contribute to the formation of specialized feeding sites or giant cells. The effector proteins interfere with… More

  • Combined Role of ACC Deaminase Producing Bacteria and Biochar on Cereals Productivity under Drought
  • Abstract Most of the cereal crops are widely cultivated to fulfil the humans food requirements. Under changing climate scenario, the intensity of drought stress is continuously increasing that is adversely affecting the growth and yield of cereal crops. Although the cereals can tolerate moderate drought to some extent, but mostly they are susceptible to severe drought stress. Higher biosynthesis of ethylene under drought stress has been reported. Many scientists observed that inoculation of 1-aminocyclopropane-1-carboxylate (ACC) deaminase producing plant growth promoting rhizobacteria (PGPR) is an efficacious tool to overcome this problem. These PGPR secrete ACC deaminase which cleavage the ACC into the… More

  • Multi-strain Inoculation with PGPR Producing ACC Deaminase is More Effective Than Single-strain Inoculation to Improve Wheat (Triticum aestivum) Growth and Yield
  • Abstract Rhizosphere bacteria that colonize plant roots and confer beneficial effects are referred as plant growth promoting rhizobacteria (PGPR). Among all PGPR, some rhizobacteria have an ability to produce ACC deaminase enzyme. This enzyme catalyzes stress ACC into a-ketobutyrate and ammonia instead of letting it to be converted to ethylene. Ethylene level rises in plants under stress conditions i.e., drought, salinity, poor soil fertility etc. As poor soil fertility is a big hurdle to achieve the optimum yield of crops, inoculation of ACC deaminase PGPR can overcome this problem to some extent. The aim of the current study was to examine… More

  • Biochar Application Enhanced Post-Heading Radiation Use Efficiency in Field-Grown Rice (Oryza sativa L.)
  • Abstract It has been shown that adding biochar to soil can improve nitrogen (N) uptake and utilization in rice (Oryza sativa L.). However, there is a lack of research on the physiological alterations of rice as a result of the changes in nitrogen uptake due to the addition of biochar. This study conducted field experiments in 2015 and 2016 with the goal of testing the hypothesis that the application of biochar would enhance radiation use efficiency (RUE) of rice by improving the plant’s ability to take in and utilize nitrogen. Our results demonstrated that the application of biochar (20 t ha−1 More
