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…
Understanding Drought Impact on Crop Yield: Stages, Mechanisms, and Adaptations.
Drought’s impact on crop yield affects plant stages differently, moderated by genotype and external environmental factors. Very early drought can inhibit germination and seedling establishment, reducing stand density and yield. Drought during reproductive and grain filling can reduce yield quantity and quality more than during the growth phases. Drought is the primary environmental stress crop… 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…
What We Learned About Roots in 2023
Most studies in 2023 focused on root responses to agricultural practices to improve yield using fewer resources. Research into the basic science of roots and the influence of biotic and abiotic factors are the second significant areas of study. Fine roots are a particular area of focus, given their importance in nutrient and water uptake… Continue reading…
