Summary: Accurate estimation of canopy chlorophyll content (CCC) is crucial for quantitative remote sensing. This study focused on maize and found non-uniform vertical distribution of leaf chlorophyll content (LCC), which affects CCC monitoring accuracy. The study analyzed LCC profiles, leaf reflectance spectra, and their correlations, finding that leaf reflectance can be used to estimate CCC directly.

Summary: This greenhouse study investigated the effects of arbuscular mycorrhizal fungi (AMF) on grapevines under drought stress. Results showed that mycorrhiza-inoculated grapevines had higher leaf water content and chlorophyll concentration compared to non-mycorrhizal grapevines. AMF colonization also increased the biomass, photosynthetic rate, stomatal conductance, and transpiration rate of grapevines, while decreasing CO2 concentration. Additionally, mycorrhizal grapevines exhibited higher photochemistry efficiency and actual quantum yield. Overall, AMF inoculation has the potential to protect grapevines under drought stress.

Summary: Leaf nitrogen, phosphorus, and potassium stoichiometry reflect plant nutrient allocation strategies, which are crucial for food security and nutrient balance in agroecosystems. Arbuscular mycorrhizal fungi (AMF) inoculation is an effective and sustainable management measure that affects nutrient uptake and utilization strategies, particularly in agricultural systems. However, the relationship between AMF and leaf nutrient stoichiometry is not well understood.

Summary: Plants can be colonized by fungi with both harmful and beneficial effects. One way the fungi colonize is by secreting effector proteins that change the plant's physiology to suit the fungus. Arbuscular mycorrhizal fungi (AMF), the oldest plant symbionts, may benefit from using effectors. Recent research has focused on understanding the function, evolution, and diversification of AMF effectors through genome analysis and transcriptomic studies. However, only a small fraction of the predicted effector proteins have been characterized, limiting our understanding of how they manipulate their host plants and which plant proteins they interact with.

Summary: The study investigated the impact of two fungicides on the performance of arbuscular mycorrhizal fungi (AMF) and found that low doses of the fungicides enhanced root colonization by AMF, while high doses suppressed their performance. The fungicides generated biphasic response curves in irradiated soil, indicating a hormetic effect on AMF.

Summary: The study found that inoculation with arbuscular mycorrhizal fungi can improve maize tolerance to salt stress by regulating the accumulation and distribution of Na+ and K+, promoting Na+ transport between roots and shoots, and maintaining the structural and functional integrity of chloroplasts.

Summary: The leaf chlorophyll content is an important vegetation parameter in carbon cycle modeling and agricultural monitoring. The study proposes a new red-edge chlorophyll index, termed chlorophyll sensitive index (CSI), to decouple the effects of canopy and soil background. Sensitivity analyses and validation results show that the CSI is resistant to variations in canopy structure and soil background, and it improves the accuracy of chlorophyll content retrieval compared to existing methods.

Summary: Microplastics have diverse effects on soil and plant growth, altering soil structure and microbial activity, which in turn affects the abundance and activity of arbuscular mycorrhizal fungi. The impacts of microplastics may also change how plants respond to other global change factors, highlighting the need for further research on their overall impact on ecosystems.

Summary: This study measured the spectral reflectance and SPAD values of rice leaves at different growth stages and analyzed the correlation between various parameters. By considering the influence of leaf water content, the accuracy of SPAD estimation may be enhanced. The findings provide technical support for estimating SPAD in rice leaves with high accuracy and for developing chlorophyll tachistoscopes.

Summary: The estimation of rice LCC was compared in two regions using UAV-based spectral images. The results showed that rice LCC had significant correlations with reflectance at different bands and vegetation indices. PLSR models were found to be more stable and accurate for LCC estimation in different regions.

Summary: The allocation of tree biomass to leaves, roots, and wood has implications for carbon residence time and storage in ecosystems. This study found that the type of mycorrhizal association, along with climate and leaf habit, significantly influenced biomass allocation. Trees associated with arbuscular mycorrhizal (AM) fungi allocated more biomass to root tissue compared to trees associated with ectomycorrhizal (ECM) fungi. Considering mycorrhizal associations could improve our understanding of ecosystem carbon storage.
