The relationship between biotic stress and plant yield affects economic decisions as well as practical development. The impact of biotic injury on crop yield impacts population dynamics, plant-stressor coevolution, and ecosystem nutrient cycling. [3] Biotic stress also impacts horticultural plant health and natural habitats ecology. It also has ...
Plant stress research looks at the response of plants to limitations and excesses of the main abiotic factors (light, temperature, water and nutrients), and of other stress factors that are important in particular situations (e.g. pests, pathogens, or pollutants). Plant stress measurement usually focuses on taking measurements from living plants.
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
Of specific interest are mechanisms and signal transduction pathways by which plants adapt to extreme environmental conditions such as high and low temperatures, drought, flooding, salinity, pathogens, and other major abiotic and biotic stress factors. The current editor-in-chief is Sergey Shabala (University of Tasmania).
Whereas a biotic stress would include living disturbances such as fungi or harmful insects, abiotic stress factors, or stressors, are naturally occurring, often intangible and inanimate factors such as intense sunlight, temperature or wind that may cause harm to the plants and animals in the area affected. Abiotic stress is essentially unavoidable.
This investigation has been extended to intergenerational nutrient exchanges, [11] the functioning of sensory motor cells, [12] the study of the impact of abiotic and biotic stress on nutrient compartmentalization and cell growth, [13] [14] and the search for specific nutrient transporter inhibitors.
Issues of sulfur nutrition of crop plants, with focus on resistance to abiotic and biotic stress were later one of her main research subjects. In 2001 Haneklaus coined with Ewald Schnug the term ‘Sulphur-Induced Resistance’ (SIR) which will become a major focus in the research portfolio of FAL/JKI.
In addition to its role in defense, SA is also involved in the response of plants to abiotic stress, particularly from drought, extreme temperatures, heavy metals, and osmotic stress. [ 50 ] Salicylic acid (SA) serves as a key hormone in plant innate immunity, including resistance in both local and systemic tissue upon biotic attacks ...
