Summary: This study investigated the impact of below-ground hydraulics on stomatal regulation during soil drying, finding that changes in root system significantly affected the relationship between transpiration rate (E) and leaf xylem water pressure (psi(leaf-x)). Plants with shorter roots required larger gradients in soil water pressure to sustain the same transpiration rate, leading to earlier non-linearity and stomatal closure.

Summary: Moderate soil drying can significantly reduce the conductance of the soil-root system, impacting root water uptake. The distribution of this altered conductance in relation to soil water resources is not well understood. This study used noninvasive sensor technology to analyze the vertical distribution of conductance in pot-grown faba bean and maize plants. The results showed that withholding water for 4 days increased the vertical gradient in soil water potential, affecting roots in different soil layers differently. Plants were able to compensate for reduced root conductance in upper, drier soil layers by locally increasing root conductivity in wetter layers, improving deep-water uptake.

Summary: Soil drying is a limiting factor for global crop production, but the impact of water uptake across different soils, species, and root phenotypes is not well understood. This study proposes a hydraulic framework to investigate how soil and root hydraulic properties interact in water uptake. The findings show that soil drying leads to a rapid decrease in soil hydraulic conductance, and root phenotypes with low root hydraulic conductance, long roots, and/or long and dense root hairs can postpone soil limitation. This has important implications for crop water use efficiency.

Summary: Root length distributions are commonly used to approximate root water uptake profiles, assuming a constant water uptake rate per unit root length. However, our study found significantly greater water uptake rates per unit length in shallower roots compared to deeper roots, challenging this assumption.

Summary: Savannas in South America contribute significantly to terrestrial net primary productivity and carbon storage. A unique dataset of 21 Cerrado sites in Southeastern Brazil was used to assess the patterns of above and belowground carbon stocks. Environmental factors and tree diversity had significant effects on carbon stocks, with belowground carbon storage being particularly important. The findings highlight the need for better management and protection of the Cerrado.

Summary: This study investigated the effects of root pruning on maize yield, water-use efficiency (WUE), and water uptake in pot and hydroponic experiments. The results showed that both small and large root pruning treatments improved WUE and root hydraulic conductivity in the residual root system. Additionally, root pruning increased grain yield under well-watered conditions. Furthermore, the study demonstrated that root pruning did not reduce leaf water potential but increased residual root hydraulic conductivity under well-watered conditions.

Summary: Plant stress experiments are commonly conducted in containers to control environmental conditions, but the container volume can affect plant growth and development. In drought experiments with grapevines, plants in different container sizes showed differences in physiological responses, highlighting the importance of considering container volume in experimental design for unbiased results.

Summary: The study examined the effectiveness of partial leaf removal in alleviating transplant shock and reducing stem tilting in large-rooted cuttings of sugi trees. The results showed that leaf removal at 25% reduced water stress in the early stage but this advantage disappeared after three months. Higher leaf removal rates resulted in larger stem incline values initially but this effect also diminished after three months. Leaf removal had limited effects on transplant shock and stem tilting, and higher leaf removal rates delayed stem growth and diameter due to the loss of photosynthetic organs.

Summary: The study suggests that Bothriochloa ischaemum responds more positively to periodic increases in soil water availability compared to Lespedeza davurica, indicating that the abundance of B. ischaemum could increase in relatively wet seasons or periods of abundant rainfall. The mixture ratio of 10:2 (B. ischaemum to L. davurica) was found to be the most compatible combination for improved biomass production, water use efficiency (WUE), and relative yield totals (RYTs) across all soil water treatments.

Summary: This study investigated the mechanism of melatonin in mitigating chromium toxicity in maize plants using transcriptomic and physiological approaches. The results showed that melatonin treatment significantly reduced the chromium content in leaves, while the chromium content in roots remained unchanged. Further analysis revealed that melatonin alleviated chromium-induced oxidative stress by affecting cell wall polysaccharide biosynthesis, glutathione metabolism, and redox homeostasis. These findings highlight the important role of melatonin in alleviating chromium toxicity in maize.

Summary: This study investigated the variations in Cd accumulation and tolerance among four maize genotypes with different root morphology, and found a positive correlation between root characteristics and Cd accumulation. Genotypes Shengrui999 and Zhengdan958 showed higher Cd accumulation and tolerance under Cd stress. Cd toxicity led to membrane degradation and reduced starch reserves in maize plants. The greater tolerance of Shengrui999 and Zhengdan958 may be attributed to factors such as root biomass, shallower root depth, higher Cd content, and accumulation of osmolytes and antioxidant activities.
