Summary
Increasing population and deteriorating agricultural land due to climate change is a major concern to mankind. The food security is at risk due to this climate change especially in arid and semiarid regions. Degradation of fertile land increases per year due to environmental stresses and the soil will not be able to produce enough food for our next generation if the effect will not be abated. Agriculture and environmental conditions are strongly linked. Plant growth rate and productivity are negatively affected by biotic and abiotic stress as a result of climate change. The environmental fluctuations cause havoc in the form of droughts, floods, salinity, rising CO2 levels, and higher temperatures. These factors have reduced plant growth and productivity, caused massive crop losses, and decreased the effectiveness of crop protection technologies. Meanwhile, global warming has increased the number of insect generations each year, leading to increased damage to a variety of crops. The biotic and abiotic stresses are reported to affect the plant metabolism thus reduces the crop yield worldwide. The plant biochemical as well as enzymatic activities are compromised during the elevation of environmental stress. Environmental stress induces oxidative burst due to the generation of reactive oxygen species (ROS), which ultimately affects the biomolecules. However, nature has equipped the plants with defense mechanism that can be used by the plants to defend and tolerate the environmental fluctuations.
Plant biologists are manipulating all scientific approaches to overcome the environmental stress and crop loss. Thus, the focus is to search for a sustainable approach to overcome the negative effects of biotic as well as abiotic stress on plant growth and yield. To overpower the environmental stress, various approaches has been tried like; external supplementation of plant growth regulators, micro and macro nutrients, use of nanoparticles and other stress alleviating agents.
To understand the effect of environmental change on plant growth and crop yield and the role of different mitigating agents, we aim to bring forth an extensive research topic “Plant Responses to changing environment: From lab to Field”, which will highlight the present scenario of environmental stress and future prospects. The research topic will cover the articles from different areas of plant science like agriculture, nanotechnology, molecular biology, genomics, metabolomics etc.
The research topic will accommodate original research papers and timely review articles on the following (but not limited to) topics:
Plant responses under environmental stress
Plant growth regulators and climate change
Biotechnological interventions in improving plant resistance against stress.
Plant signalling molecules and crop improvement.
ROS homeostasis in plants by alleviating agents
ROS and Plant immunity
ROS as signalling molecules
Nanoparticles in alleviating environmental stress in plants
Mitigation of biotic stress through Plant growth promoting rhizobacteria (PGPRs)
Nutrient supplementation enhances plant stress tolerance
