Summary: The study conducted a transcriptomic analysis of a susceptible and a resistant pepper cultivar infected with Xanthomonas campestris pv. vesicatoria (Xcv), identifying a total of 38,269 expressed genes with 11,232 differentially expressed genes (DEGs). Functional enrichment analysis revealed key pathways involved in plant-pathogen interaction, MAPK signaling, plant hormone signaling, and secondary metabolism. Furthermore, the study identified 1,599 defense-related genes potentially regulating pepper resistance to Xcv, highlighting the importance of genes such as pattern recognition receptors, mitogen-activated protein kinases, calcium signaling molecules, and transcription factors.

Summary: In the process of bell pepper (Capsicum annuum) fruit ripening, the conversion from chloroplasts to chromoplasts involves significant changes in the levels of various enzymes, including maintenance of high levels of specific complexes and enzymes, an increase in enzymes related to heterotrophic plastid metabolism, and a shift in abundance of enzymes related to chlorophyll catabolism and carotenoid biosynthesis. Despite these changes, certain proteins remain constant, suggesting a unique metabolic pathway in non-climacteric fruits like bell pepper.

Summary: This study used RNA-seq technology to investigate the mechanism of VBNC state induced by copper ion in Xcc. The results showed significant changes in gene expression and enriched metabolism-related pathways in different VBNC stages. Genes associated with cell motility were down-regulated, while pathogenicity related genes were up-regulated. This study not only summarized the related pathways of VBNC state, but also provided new ideas for studying gene expression profiles in different survival states under stress.

Summary: Xanthomonas effector protein XopS enhances disease susceptibility by repressing defense gene expression and suppressing stomatal immunity through interaction with and inhibition of WRKY40, a transcriptional regulator. XopS manipulation of WRKY40 stability alters downstream gene expression and phytohormone crosstalk to promote pathogen proliferation.

Summary: This study aimed to monitor the persistence of Xanthomonas campestris pv. campestris (Xcc) in field soil in central Europe, using different PCR assays. It was found that Xcc can persist in soil for up to two years, and the nested real-time PCR method showed higher sensitivity in detecting Xcc in soil compared to conventional PCR.

Summary: Research on plant growth lighting shows that spectral quality significantly affects the growth outcomes of bell pepper seedlings. Blue light plays a crucial role in reducing plant height, increasing stem diameter, leaf area, dry weight partitioning, and compactness scores, while green light enhances leaf area.

Summary: The study revealed the key role of the effector gene xopJ2 in the dispersal and evolution of Xanthomonas perforans populations on tomato, showing that this gene can enhance the pathogen's fitness in the field, leading to its rapid fixation within cropping seasons. Through simulation experiments and logistic model analysis, it was found that wild-type bacteria dispersed approximately three times faster than xopJ2 mutants, further demonstrating the significant impact of the xopJ2 gene on the population dynamics of Xanthomonas perforans.

Summary: The study reveals substantial functional diversity in commensal peptide derivatives of flagellin, with most peptides evading immune recognition and others manipulating immunity through signal modulation. Plant-associated communities are enriched for immune evading peptides, but immune-activating peptides become enriched under physiological stress, suggesting a complex interplay between the immune system and commensal microbiota.

Summary: Plant nucleotide-binding leucine-rich repeat receptors (NLRs) play a crucial role in regulating immunity and cell death, with helper NLRs being essential for the function of many sensor NLRs. NRG1.1 and ADR1 are two helper NLRs that mediate cell death through Ca2+ influx, by forming Ca2+-permeable cation channels to directly regulate cytoplasmic Ca2+ levels.

Summary: This study reveals two cell-death regulatory modes for plant NLR immune receptors CHS3/CSA1 pairs, one mediated by the ID domain and the other relying on detecting perturbation of an associated co-receptor. The ancestral Arabidopsis CHS3/CSA1 pair likely gained a second recognition specificity and regulatory mechanism through ID acquisition while balancing selection maintains ID and non-ID alleles.
