Understanding the Impact of High Temperatures on Crop Roots
Due to climate change-related high temperatures on crop roots, root architecture is altered. Roots change the carbohydrate/amino acid ratio and lipid metabolism to limit growth disruption and activate heat pathways. Temperature-induced hormone changes trigger signals to activate root responses to stress. Roots must also deal with climate change effects like drought, nutrient deficiency, salinity, and… Continue reading…
Climate Change Effects on Plant Development: Comprehensive Insights
Climate change can alter plants’ roots, vegetation, and reproductive development. Climate change effects on plant development can sometimes be similar across species or depend on tissue, species, genotype, and development stage. Plants are most sensitive to temperature and drought stress effects during the reproductive phase. Several features characterize climate change, like higher concentrations of greenhouse… Continue reading…
Understanding Drought Resistance Strategies: A Guide to Plant Adaptation
Drought Resistance Strategies include any plant mechanism that responds and adapts to drought, commonly called drought resistance. Plants use drought escape mechanisms to prevent encountering climatic established drought conditions by altering their lifespan. Drought avoidance strategies avoid the adverse impacts of mild and acute drought on cells by reducing plant water loss. Stress tolerance mechanisms… Continue reading…
Understanding Fine Root Dynamics: Key Insights and Methodologies
Fine roots have a diameter of 0.1–2 mm and are essential for nutrient acquisition for individual plants and carbon and nutrient cycling for ecosystems. Research shows fine roots are not a single group; root order determines form, anatomy, physiology, and function. Fine root age is another significant factor that influences functioning and dynamics. Though fine… Continue reading…
The Impact of Invasive Species: Managing Threats to Forest Ecosystems
The Impact of Invasive Species in forests with closed canopy is more resistant to invasion by alien plant species due to limited light in the understory. Invasives’ success depends on species-specific and site-specific factors. Competition for space, water, and nutrients also keeps invasives away. Natural forests are more resistant to invasives than planted or managed… Continue reading…
How Does the Rhizosphere Effect Influence Plant Growth and Soil Health?
The rhizosphere is the soil surrounding the plant root and soil interface. Root exudates, controlled by plant species, functional type, root traits, and biomes, can determine the biology, physics, and chemistry of the rhizosphere effect. The rhizosphere effect can enhance nutrient availability and defense at the plant level; carbon and nutrient cycling and possible bioremedial… Continue reading…
Advances in the Measurement of Root Turnover with Minirhizotron Technology
Root turnover rates are complex to measure as growth and death co-occur in plants. Minirhizotron is a standard method for estimating root turnover as it is non-destructive, rapid, and accurate. One challenge in the widespread use of minirhizotrons for root turnover is the lack of analysis methods to directly convert root scans to turnover estimation.… Continue reading…
Drought Effects on Forest Productivity
The effects of increasingly frequent and severe droughts are reported globally. Forest productivity decreases due to reduced growth, canopy dieback, and tree mortality. Drought effects are not even and are influenced by internal and external factors. Some adaptation measures to drought-proof forests are suggested based on available information. Drought intensity, frequency, duration, and extent are… Continue reading…
Minirhizotron Systems for Root Disease Detection
Root diseases are a significant issue in reducing crop yields globally. The damage and symptoms caused by root diseases change morphology and growth dynamics that images and scans can detect. Minirhizotron systems can detect a wide range of root changes reflecting various levels of root disease severity, providing a novel detection method. Root diseases are… Continue reading…
How Wildfire Affects Tree Physiology
Wildfire effects on trees depend on fireline intensity and residence time and can occur from heat transfer or smoke. To understand how this process unfolds, we dive deep into the study of how wildfire affects tree physiology. Wildfire effects can be first-order or second-order and are evaluated based on carbon and water transport and are… Continue reading…
