Prion Switching in Response to Environmental Stress
Evolution depends on the manner in which genetic variation is translated into new phenotypes. There has been much debate about whether organisms might have specific mechanisms for "evolvability," which would generate heritable phenotypic variation with adaptive value and could act to enhance the rate of evolution. Capacitor systems, which allow the accumulation of cryptic genetic variation and ...
متن کاملPlant Response to Water-deficit Stress
Drought, a period of abnormally dry weather, results in soil-water deficit and subsequently plant-water deficit. The lack ofwater in the environment constitutes a stresswhen it induces an injury in the plant. Water deficit in the plant disrupts many cellular and whole plant functions, having a negative impact on plant growth and reproduction. Crop yields are reduced by 69% on average when plant...
متن کاملMicrorna-mediated Plant Development and Response to Environmental Stress in Perennial Grasses
MicroRNA528 (miR528) is a conserved monocot-specific small RNA that has the potential of mediating multiple stress responses. So far, however, experimental functional studies of miR528 are lacking. Here, we report that overexpression of the rice (Oryza sativa) miR528 (Osa-miR528) in transgenic creeping bentgrass (Agrostis stolonifera L.)
متن کاملPlant acclimation to environmental stress: a critical appraisal
Being a prime source of food, agriculture sustains almost all life-forms on the Earth. However, apart from natural calamities, a range of man-made activities are causing significant increase in environmental stresses for plant growth. Adverse conditions, in turn, restrict crop plants to reach their full genetic potential of producing high yield (Anjum et al., 2014). Also, agriculture is under p...
متن کاملMetabolomics for plant stress response.
Stress in plants could be defined as any change in growth condition(s) that disrupts metabolic homeostasis and requires an adjustment of metabolic pathways in a process that is usually referred to as acclimation. Metabolomics could contribute significantly to the study of stress biology in plants and other organisms by identifying different compounds, such as by-products of stress metabolism, s...
