Pea plants are commonly grown in temperate regions throughout the world. [49] However, this adaptation allows plants to anticipate abiotic stresses such as drought. In 2011, Falik et al. tested the ability of unstressed pea plants to sense and respond to stress cues by inducing osmotic stress on a neighboring plant. [50]
Calcium signaling is the use of calcium ions (Ca 2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca 2+ is important for cellular signalling , for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins .
Hydraulic signals in plants are detected as changes in the organism's water potential that are caused by environmental stress like drought or wounding. [1] The cohesion and tension properties of water allow for these water potential changes to be transmitted throughout the plant. Plants respond to external stimuli through thigmomorphogenesis.
In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [1] [2] [3] Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. [3]
Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
Other research finds that expression of the HvMYB1 gene in barley is increased under drought stress, and when over-expressed in transgenic barley plants, was found to increase drought tolerance. [20] Induced over-expression of K + transporters in barley plants has also been found to increase drought tolerance, due to the many roles K + plays in ...
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.
Calmodulin is a small, highly conserved protein that is 148 amino acids long (16.7 kDa). The protein has two approximately symmetrical globular domains (the N- and C- domains) each containing a pair of EF hand motifs [5] separated by a flexible linker region for a total of four Ca 2+ binding sites, two in each globular domain.
