Abstract Plant trichomes vary in their structure and cellular composition. Glandular trichomes contain a bulk of specific (secondary) metabolites of diverse nature. Trichomes are connected with various adaptive processes, which include protection against herbivores and pathogens as well. Our study investigates the allelopathic contribution of structures present on the leaf surface of Nicotiana plumbaginifolia Viv. against seedling growth of Cicer arietinum L. The infusion obtained after dipping Nicotiana leaves in Dichloromethane (DCM) for 10 seconds (s) was the most phytotoxic among all the infusions. The observed inhibition in Cicer growth was not only dependent on type of infusion but More >

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. More >

Abstract Members of the Pathogenesis Related (PR) 10 protein family have been identified in a variety of plant species and a wide range of functions ranging from defense to growth and development has been attributed to them. PR10 protein possesses ribonuclease (RNase) activity, interacts with phytohormones, involved in hormone-mediated signalling, afforded protection against various phytopathogenic fungi, bacteria, and viruses particularly in response to biotic and abiotic stresses. The resistance mechanism of PR10 protein may include activation of defense signalling pathways through possible interacting proteins involved in mediating responses to pathogens, degradation of RNA of the invading… More >

Abstract This research uses the immature embryos of inbred maize lines (GSH9901, Hi01, Hi02, and Chang 7-2) as receptor materials to establish the callus induction system. These inbred lines provide the receptor materials for the genetic regeneration of maize and the verification of the genetic functions of maize. The factor experiment and orthogonal experiments were used to investigate the impacts of different genotypes, immature embryo size, shield orientation, 2, 4-D concentration, proline concentration, and folic acid concentration on the induction rate of embryogenic callus tissue. A sensitivity experiment testing glyphosate (Bar) and an antibiotic (Cefotaxime sodium)… More >

Abstract Condition monitoring is implementation of the advanced diagnostic techniques to reduce downtime and to increase the efficiency and reliability. The research is for determining the usage of advanced techniques like Vibration analysis, Oil analysis and Thermography to diagnose ensuing problems of the Plant and Machinery at an early stage and plan to take corrective and preventive actions to eliminate the forthcoming breakdown and enhancing the reliability of the system. Nowadays, the most of the industries have adopted the condition monitoring techniques as a part of support system to the basic maintenance strategies. Major condition monitoring… More >

Abstract In the era of climate change, abiotic stresses (e.g., salinity, drought, extreme temperature, flooding, metal/metalloid(s), UV radiation, ozone, etc.) are considered as one of the most complex environmental constraints that restricts crop production worldwide. Introduction of stress-tolerant crop cultivars is the most auspicious way of surviving this constraint, and to produce these types of tolerant crops. Several bioengineering mechanisms involved in stress signaling are being adopted in this regard. One example of this kind of manipulation is the osmotic adjustment. The quarternary ammonium compound glycinebetaine (GB), also originally referred to as betaine is a methylated… More >

Abstract Heavy metal contamination of land and freshwater resources is a serious concern worldwide. It adversely affects the health of animals, plants and humans. Therefore, remediation of toxic heavy metals must be highly considered. Unlike other techniques, phytoremediation is a holistic technology and can be used in large scale for soil remediation as it is costless, novel, environmentally-safe and solar-driven technology. Utilization of non-edible plants in phytoremediation is an ingenious technique as they are used to generate new bioenergy resources along with the remediation of contaminated soils. Some nonfood bioenergy crops such as Salix species, Miscanthus… More >

Abstract An increased interest in the antioxidant effects of medicinal plants has developed in recent years. Identifying antioxidant compounds present in medicinal plants and elucidating the mechanism by which they prevent oxidation have been the focus of the research community. We performed a systematic and exhaustive review aimed at analyzing the available data regarding the beneficial effects of secondary metabolites in plants. The result of this review is presented as a description of free radicals, as well as cellular and physiological oxidative stress, is provided. The origin and source of antioxidant compounds, and the cellular and More >

Abstract The floor response spectrum (FRS) of a nuclear power plant (NPP) structure considering nonlinear behavior of shear walls is numerically investigated. The Hysteretic Material from OpenSees program is applied to a lumped-mass model to consider the nonlinear hysteretic behavior of the element representing the shear wall. Parameters that determine the hysteretic behavior are changed to examine the effects of the parameters on the resulting FRS. The pinching effect, damage due to ductility and energy, and degraded unloading stiffness can be considered with changes in parameter values. The hysteretic behavior of the structure with different parameter values… More >

Abstract Chemical elements, such as carbon (C), nitrogen (N) and phosphorus (P), are major limiting nutrients in arid and semiarid grasslands and their stoichiometry (C:N:P) is a very important ratio to determine. In addition, it is critical to understand how plant stoichiometry responds to multiple environmental factors at the species level. In this study, we conducted a greenhouse experiment to investigate the effects of salt stress (4 g NaCl/kg soil), drought (35% of the soil water holding capacity) and N addition (10 g N/m²), as well as their interactions, on C, N and P concentrations and C:N:P… More >
