Summary: The study of plant growth state relies on root architecture parameters, with root segmentation being crucial to measuring these parameters. A new method based on a convolutional neural network was proposed for pixel-level segmentation of rice roots under strong noise, achieving an intersection over union (IoU) of 87.4%. This approach provides an automatic and fast pixel-level root segmentation method, essential for root morphology analysis.

Summary: This paper proposes an improved power line segmentation model based on Deeplabv3+ (PL-Deeplab), which addresses the problems of complex background interference and thin structure of power lines in aerial images. The model utilizes a multibranch concatenation network (MCNet), a one-shot aggregation feature pyramid (OSAFP), and a feature fusion module (FFM) to accurately segment the power lines. Experimental results on a public dataset demonstrate the superiority of the proposed model in completing the power line inspection task and ensuring security for UAV power line inspection.

Summary: The real challenge in separating leaf pixels from background pixels in thermal images lies in factors such as emitted and reflected thermal radiation from the plant, absorption of reflected radiation by greenhouse humidity, and external environment. The proposed TheLNet270v1 achieved 91% accuracy in distinguishing canopy pixels from background pixels and segmenting the image into leaf and background classes. Through evaluation with over 13,766 images, training and validation accuracies of 95.75% and 95.23% were achieved, without overfitting. This research focuses on developing a deep learning technique for automatically segmenting thermal images to monitor canopy surface temperature in greenhouses continuously.

Summary: A positive correlation was found between root system size and high-affinity nitrate uptake in a core set of Arabidopsis natural accessions, highlighting the beneficial role of exploratory root organ in plant nitrogen acquisition. The study evaluated the role of root phenes in nitrogen acquisition and biomass production in different accessions of Arabidopsis thaliana. The low nitrogen treatment resulted in increased root to shoot biomass ratio and enhanced proliferation of lateral roots and root hairs. Greater biomass production could be achieved through increased root length or specific root hair characteristics.

Summary: Members of the B family of membrane-bound ATP-binding cassette (ABC) transporters play important roles in auxin efflux in plants. This study integrates ABCB localization data into a multicellular model to predict the impact of ABCB-mediated auxin transport on organ-scale distribution. The results suggest that ABCBs enable auxin efflux independently of PINs, but PINs predominantly mediate auxin efflux when co-localized with ABCBs.

Summary: The genetic basis of root system architecture and resource adaptive responses in wheat was studied using a high-throughput germination paper-based plant phenotyping system and quantitative trait locus (QTL) analysis. Significant genotypic and nitrate-N treatment variation was found for seedling traits, and a total of 59 seedling trait QTLs were identified. Transcriptomic analysis revealed gene enrichment in N-related biological processes and differentially expressed genes related to root angle response. These findings provide genetic insight into root system architecture and plant adaptive responses, and offer targets for improving nitrogen capture in wheat.

Summary: The conversion from conventional tillage to no-tillage soil management practices improves aggregate stability and earthworm populations. UK farmers found that middened soil, which accounts for up to 42% of the soil surface, has significantly more earthworms than general soil. In a recent experimental field trial, middened areas covering 13% of the trial showed improved aggregate stability and porosity compared to general soil. These findings emphasize the importance of considering middens in assessing soil quality and health in arable systems.

Summary: Root angle in crops is an important trait for efficient utilization of soil resources. This study identifies a regulatory gene called EGT1 that controls root angle by affecting cell wall stiffness in elongating root cortical tissue. Mutations in the EGT1 gene result in a striking root phenotype with steeper growth angles in barley and wheat. These findings suggest that EGT1 plays a crucial role in exerting an antigravitropic mechanism to control root angle in cereal crops.

Summary: This paper reviews 34 studies that demonstrate the influence of zero-tillage (ZT) on porosity, depending on soil texture, pore size class, and depth. ZT can also affect important transport mechanisms that impact the fate of agrochemicals in soils, although the effects on hydraulic transport are less clear.

Summary: Leaf structure plays a crucial role in photosynthesis, but the relationship between a single structural parameter and the overall photosynthetic performance is still debated. In this study, a mechanistic model called eLeaf was developed to capture the photosynthetic performance of rice leaves under various environmental conditions. The model successfully quantified the importance of different elements by analyzing imaging data and biochemical measurements. The results showed that photosynthetic metabolism was the major driver of increased carbon assimilation under elevated CO2 levels, and various structural elements made positive and negative contributions. The findings provide theoretical support for experimental data and highlight the significance of leaf structural plasticity in improving crop photosynthesis.
