Summary: Chitosan shows significant inhibition on the mycelial growth and spore germination of Phytophthora infestans, reducing its resistance to adverse conditions and having synergistic effects with pesticides. It also induces resistance in potatoes to the pathogen, with transcriptome analysis showing effects on cell growth and key pathways. This study provides new insights for the development of chitosan as an eco-friendly solution for controlling potato late blight.

Summary: Late blight of potato caused by Phytophthora infestans is one of the most damaging diseases affecting potato production worldwide. In this study, 357 root fungal endophytes isolated from four solanaceous plant species obtained from Kenya were evaluated for their antagonistic activity against P. infestans. Three endophytes with pronounced inhibitory activity against P. infestans were identified, suggesting their potential use in late blight control strategies.

Summary: This study aimed to screen wild tomato Solanum habrochaites accessions for resistance to late blight and characterize their morphological characters. Three accessions (LA1777, LA2167, and LA2556) were found to be resistant to late blight. LA1777 showed the highest resistance and could be used as a source for breeding blight-resistant tomatoes. Hybrid combinations using LA1777 as a male parent also showed encouraging results. The morphological characterization of the accessions provided valuable information for breeding superior tomato cultivars.

Summary: This study focuses on a nuclear-targeted effector Pi07586 released by the highly destructive plant oomycete pathogen Phytophthora infestans. It is found that Pi07586 can effectively suppress plant immunity by inhibiting the expression of specific genes and reducing the levels of plant hormones. These findings enhance our understanding of the intricate relationship between P. infestans and host plants and shed new light on plant immune modulation.

Summary: Soil microorganisms, particularly Actinomycetes, play a crucial role in soil fertility. This study isolated and characterized 175 Actinomycetes from soil samples in Sudan and found that they exhibited strong anti-oomycete activity. Co-inoculation with these Actinomycetes led to different morphological effects on the oomycete Phytophthora infestans. Furthermore, some active strains showed significant protection against the pathogen in leaf assays and reduced disease progress in full plants assays, highlighting their potential for crop protection.

Summary: This study identified 36 differentially expressed genes, including nucleotide binding site-leucine-rich repeat and pathogenesis-related disease resistance genes, in highly resistant and susceptible tomato inbred lines using transcriptome sequencing. Two pathogenesis-related genes, Solyc08g080660 and Solyc08g080670, were found to have unique responses to Phytophthora infestans and were confirmed to play roles in late blight resistance through gene overexpression and editing techniques. Additionally, co-transformation of both genes showed a greater effect on disease resistance compared to individual genes.

Summary: This article explores the use of unmanned aerial vehicles (UAVs) in downlink NOMA networks to improve connectivity in 5G networks. The outage probability for both orthogonal multiple access (OMA) and NOMA is derived to determine if communication from the ground node to the destination node is possible. Additionally, power allocation is optimized to maximize energy efficiency, and a multiple interference cancellation scheme is used to enhance signal quality at the receiving end.

Summary: This paper analyzes the functional estimates of short duration mean power generation and associated variability at a site near the port town in peninsular India, where a proposed installation of two-body floating heave buoy wave energy convertor is supposed to be carried out. The study focuses on the application of the concept of capture width function for estimating power output and variability of WEC units that capture energy through oscillatory dynamics of masses, as well as the impact of multi-mode power capture on short duration output power variability. The comparison with the Pelamis WEC shows that it is a more competitive alternative in terms of output power variability compared to floating heave buoys.

Summary: This paper analyzes the secrecy performance of a cooperative communication network, where the source transmits information to the destination via multiple relays with multiple antennas, and an eavesdropper can only eavesdrop on the relay. Due to deep fading and shadowing, there is no direct link between the source and the destination, and the signal transmission is completed in two phases: broadcasting and relaying. Each relay follows the decode and forward protocol and receives the information signal with multiple antennas. A selected relay harvests energy from the received signals and transmits both information and jamming signals. The results show that a selected relay can harvest 0.3706 joules of energy with a 5-antenna array when the source transmits the information signal with 5 dBW power. It is also observed that the performance improves by 99.24% when using a 4-antenna system compared to a 2-antenna system when the secrecy threshold is 1 bit/s/Hz. The secrecy performance is measured using the secrecy outage probability (SOP), and a closed-form expression of the SOP is derived and verified with simulation results.

Summary: Wearable plant sensors have great potential in smart agriculture. This paper introduces a multimodal wearable sensor attached to the lower leaf surface for continuous monitoring of plant physiology through tracking biochemical and biophysical signals. The sensor integrates VOCs, temperature, and humidity detection into one platform, with the attachment position chosen based on stomata density to enhance signal strength. The platform enables various stress monitoring applications and a machine learning model was developed for early detection of tomato spotted wilt virus using the sensor data.

Summary: Potato and tomato are the most economically important vegetable crops in Egypt and worldwide. The winter crops in Egypt are susceptible to late blight caused by Phytophthora infestans. In this study, P. infestans isolates from potato, tomato, and eggplant were characterized, and it was found that all isolates belonged to the A1 mating type with varying levels of sensitivity to metalaxyl. The results also showed that the eggplant isolate had higher sporulation capacity and was able to infect potato and tomato.
