Summary: As one of the most destructive bacterial phytopathogens, Ralstonia solanacearum causes significant annual yield losses. Understanding the functional mechanisms of key factors mediating R. solanacearum-plant interactions, such as type III effectors, can help protect crops. The study focused on the effector RipAW and its role in triggering plant immunity, showing that its E3 ligase activity is not essential for immunity but the N-terminus, NEL domain, and C-terminus are required for RipAW-induced cell death.

Summary: Plant pathogens affect crop yields. Plants have evolved innate immunity based on NLR immune receptors that detect pathogen-derived effectors. Helper NLRs support the function of sensor NLRs, but the mechanism is not fully understood. This study uncovers the formation of resistosomes by Rpi-amr3 sensor NLR and helper NLRs NRC2 and NRC4, highlighting the importance of NRC resistosome formation in developing disease-resistant crops.

Summary: As a destructive plant pathogen, Phytophthora infestans secretes specific proteins called RxLR effectors that facilitate infection. One of these effectors, PiAvr3b, causes a specific immune response and also suppresses the general immune response. The molecular basis of these dual activities has been unknown, but this study found that specific amino acids in PiAvr3b were responsible for both activities. The localization of PiAv3b within the cell also plays a role in its ability to stimulate or suppress immune responses.

Summary: Plant pathogens rely on effector proteins such as Avh241 to suppress host immune responses by targeting critical components like NDR1, allowing for successful colonization. Avh241 disrupts the function of NDR1 by suppressing NDR1-mediated immune responses, showcasing an effective counter-defense mechanism used by Phytophthora during infection.

Summary: The Fry gene plays a crucial role in morphogenetic processes during gastrulation in Xenopus, impacting cell movement and morphological polarization. Additionally, Fry is involved in the regulation of dorsal mesoderm gene expression during vertebrate development. Functional interaction between Fry and NDR1 kinase suggests an evolutionarily conserved complex required for morphogenesis.

Summary: Plant nucleotide-binding leucine-rich repeat receptors (NLRs) are immune receptors that are activated by direct or indirect interactions with virulence effectors. The activation of NLRs triggers a strong immune response and disease resistance. However, the immune response can be suppressed by virulence effectors, and recent observations suggest that localized acquired resistance (LAR) plays a key role in preventing pathogen spread.

Summary: Pathogens and hosts are locked in an evolutionary arms race, with pathogen effectors targeting host proteins and host proteins evolving to sense and counteract these effectors. Type III effector proteases are common among bacterial pathogens and modify host proteins irreversibly. Studying effector proteases in plants provides insights into how pathogens evade host immune responses, and how hosts detect and defend against these effectors.

Summary: During pathogenesis, effector proteins secreted by the pathogen into the host plant provide virulence activity for invasion. Recognition of these effectors by the host plant triggers a robust immune response. This study uncovers the uncoupling of effector processing and recognition in the lettuce host for the AvrRps4 family of effectors, and reveals distinct structural requirements for perception by lettuce among different family members.

Summary: Programmed cell death (PCD) in animals consists of lytic and non-lytic forms, with membrane disruption and integrity being key distinguishing features. Recognition receptors play a crucial role in regulating cell death programs, protecting hosts from microbial pathogens. The conservation and unique aspects of PCD, such as ferrroptosis, are shared among bacteria, animals, and plants, with immune domains acting as arsenal modules to induce PCD suicide upon stresses for host community defense.

Summary: This study demonstrates that red light detection using the RFP channel of a multipurpose fluorescence imaging system can be used to visualize programmed cell death in plant tissues, providing a faster, safer, and nondestructive method to evaluate the magnitude of programmed cell death and plant immune responses. This novel approach offers a more sensitive and objective way to screen for differences in symptom severity in plant-pathogen interactions and quantify the intensity of the plant response to immunological patterns.

Summary: Cell death is a significant physiological process in living organisms, which can be either programmed or unprogrammed. Recent studies have revealed that numerous proteins regulate both cell death and immunity in plants. This review focuses on the molecular regulation and underlying mechanisms of these proteins involved in cell death and plant immunity. Additionally, potential approaches to enhance plant immunity without compromising plant growth are discussed.

Summary: In this study, high-throughput transcriptome sequencing analysis was conducted to characterize gene expression profiles during the development and ripening of paprika fruit. Differential gene expression analysis revealed differentially expressed genes at different stages of fruit development and ripening. Pathway enrichment analysis showed that sugar metabolism-related pathways, especially starch and sucrose metabolic pathways, were highly enriched. These findings provide a foundation for further research on genes related to sugar metabolism in the developmental stages of paprika fruit.
