What We Learned in 2025 About Root Morphology
In 2025, root aging and senescence were in focus, as they can alter soil properties that affect vegetation’s effectiveness for restoration and land stability. Another trend was leveraging and improving soil beneficial microbial communities through intercropping and artificial inoculations to enhance crop sustainability. Belowground studies are diversifying into plant organs other than roots, such as… Continue reading…

What Is Root System Architecture and Why Does It Matter?
The root system architecture in plants is complex and dynamic. The factors that determine root form, structure, and function are plant type, root age, and environmental conditions. The available data is still insufficient to provide a comprehensive picture of the influence of factors on root system architecture. The function of root system architecture has been… Continue reading…
Watching Wetland Soils Change in Real Time: Auburn University’s Innovative Use of the CI-600 Rhizosphere Camera
Understanding how soils transition between oxidized and reduced states is essential for accurately classifying and protecting wetlands. Traditional techniques such as the Indicator of Reduction in Soils (IRIS) method provide valuable data. Still, they rely on periodic sampling and the destruction of multiple test tubes, limiting both temporal resolution and sustainability. Researchers at Auburn University… Continue reading…
CI-600 Root Imager vs. Soil Core + Lab Root Scanning: Which Is Faster and More Reliable?
Root research is one of the trickiest aspects of plant science. The hidden half of plants—buried in soil, intertwined with microbes and moisture—holds key insights into nutrient uptake, stress tolerance, and overall plant health. For decades, scientists have relied on soil coring and lab scanning to study roots, but the process is time-consuming and inherently… Continue reading…
What is the Importance of Leaf Area Index?
Leaf area index (LAI) is a key vegetation parameter used in plant research. Global collections of LAI show that plantations have the highest LAI and deserts have the least LAI. Temperate forests have higher LAI than tropical forests. LAI is used to increase food security, support forest research and management, and track the effects of… Continue reading…
How Do Stomatal Traits and Transpiration Efficiency Impact Crop Yield?
Stomatal traits must meet mesophyll demand for CO2, conserve water, and maintain optimum leaf temperatures for higher transpiration efficiency. The stomatal traits associated with transpiration efficiency include size, density, patterning, guard cells, and responsiveness to environmental factors. So far, no crop breeding effort using stomatal traits has been able to prevent water loss/ transpiration without… Continue reading…
What Are the Key Root Traits to Improve Transpiration Efficiency?
Root traits are one of the main factors influencing transpiration efficiency or the yield produced per unit of water transpired. The root traits to improve transpiration efficiency are rooting depth, root: shoot ratio, density, root hairs, and mucilage. No root architecture type suits all species or even all hydrological conditions. Transpiration efficiency is used to… Continue reading…
