Summary: In this study, ten strains of Kiwifruit bacterial canker were isolated and sequenced, revealing divergences in pathogenicity and pathogenic-related genes among the strains. Pseudomonas syringae pv. actinidiae infection re-programmed the expression of host genes, with down-regulation of genes involved in plant-pathogen interactions, especially calcium signaling transduction and fatty acid elongation. These findings provide insights into understanding the molecular mechanism of Psa-kiwifruit interactions and improving resistance in the kiwifruit crop.

Summary: This study compares the pathogen susceptibility and defence gene inducibility between Actinidia arguta cultivar 'Hortgem Tahi' and two cultivars of A. chinensis, 'Hayward' and 'Zesy002'. The results show that different cultivars exhibit different resistance to different pathogens, and the gene expression is affected by treatments with ASM and MeJA. The Ch-Glu inducer demonstrates its potential effectiveness as an alternative to actual pathogen inoculation.

Summary: The study showed that the plant hormone JA accumulated in the susceptible kiwifruit cultivar 'Hongyang' but decreased in the resistant cultivar 'Jinkui' in response to Psa. Transcriptomic and proteomic analyses of 'Jinkui' identified multiple genes and proteins involved in the response to Psa infection, including the R2R3-MYB transcription factor AcMYB16, which acts as a repressor in regulating kiwifruit's response to bacterial pathogens.

Summary: Kiwifruit bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa) has been the most destructive disease for kiwifruit plants. In this study, 62 cultivars of A. chinensis were evaluated for Psa resistance, and the activities of defense-related enzymes were analyzed. The results showed a higher percentage of Psa-resistant A. chinensis cultivars compared to the recognized Psa-tolerant cultivar Hayward. Some red- and yellow-fleshed cultivars were found to have strong tolerance to Psa. The study also revealed a positive correlation between the activities of two enzymes and the resistance of the test cultivars. These findings enhance the understanding of A. chinensis cultivars' resistance to Psa and provide a basis for the use of existing cultivars and breeding improved Psa-resistant ones.

Summary: Bacterial canker, the most serious disease of kiwifruit caused by Pseudomonas syringae pv. actinidiae, is controlled by the key plant defense hormone salicylic acid and its mimic, ActigardTM. Research demonstrates that ActigardTM treatment induces expression of salicylic acid defense genes to limit pathogen growth and prevent disease symptoms.

Summary: By analyzing the transcriptomic profiles of kiwifruit shoots, it was found that different varieties have different defense mechanisms against Pseudomonas syringae pv. actinidiae (Psa). The PTI and cell walls play important roles in Maohua's defense against Psa infection, while the ETI is crucial in Hongyang's defense against the pathogen.

Summary: The combination of red and blue light has significant effects on the growth and photosynthesis of Actinidia chinensis. Monochromatic red and blue lights have different effects on the colonization and infection of the pathogen. Blue light primarily reduces disease symptoms by modulating pathogen virulence rather than enhancing plant defenses.

Summary: Pseudomonas syringae pv. actinidiae (Psa) causes bacterial canker, a devastating disease threatening the Actinidia fruit industry. In the study, the researchers identified a protein called ZAR1 that can recognize HopZ5 and trigger cell death, suggesting a potential non-host resistance mechanism against Psa. They also found that ZAR1 and RPM1 proteins have specific requirements for conferring resistance to different strains of P. syringae carrying HopZ5. Additionally, the study revealed the involvement of SOBER1 in regulating these resistance responses.

Summary: Ethylene interacts with other plant hormones to modulate plant metabolism, affecting defense mechanisms and stomatal regulation. In the case of Pseudomonas syringae pv. actinidiae, the production of ethylene by the highly virulent biovar may play a role in overcoming host immune responses. This study suggests that ethylene production by the pathogen could be a recently evolved virulence trait in the ongoing battle between plant and pathogen.

Summary: This study found that fruit-associated microbiota play a significant role in determining fruit volatile emissions, with bacteria contributing to the construction of fruit aroma. Sterile treatment significantly decreased the levels of various aroma compounds in fruit, and reintroducing bacteria could only partially restore their emission. The study also identified significant correlations between specific bacterial taxa and volatile emissions, suggesting that controlling microbial colonization could enhance fruit aroma in the future.

Summary: Exome sequencing-based allele mining in barley reveals that HvCBF14, rather than CNV at the Fr-H2 locus, is the main gene responsible for frost tolerance. Analysis of SNPs and read counts identified new deletions linked to reduced vernalization requirement, and highlighted the importance of HvCBF14 in controlling frost tolerance. This study provides a powerful resource for discovering novel alleles at relevant genes in barley.

Summary: This review focuses on the impact of antioxidants-rich cereal and Solanaceae derived foods on human health. It discusses strategies for increasing the antioxidant level of grains and fruits and examines the influence of agronomic practices and food processing on antioxidant properties. Despite supporting evidence from in vitro and animal studies, further clinical research is needed to confirm the effects of antioxidant-rich foods on human health.

Summary: In this study, a total of 261 barley accessions were phenotyped for culm diameter and culm wall thickness using an image analysis-based protocol. Genome-wide association studies revealed 192 quantitative trait loci (QTLs) associated with these traits, including 21 loci that impact lodging without affecting plant height. This research provides insights into the genetic control of culm morphology in barley and highlights the potential for improving lodging resistance and yield stability.

Summary: Strawberry production faces challenges from various stresses like drought, soil salinity, and the angular leaf spot disease caused by Xanthomonas fragariae. Studies have focused on developing commercial products with combinations of different Plant-Growth-Promoting microorganisms, but their effectiveness is inconsistent due to various factors. Selecting beneficial microorganisms from crop-specific microbiota can help overcome these limitations and promote sustainable agriculture. In vitro and in vivo tests on strawberry plants identified Pseudomonas fluorescens, Stenotrophomonas rhizophila, and Agrobacterium rubi as strains that significantly increased plant growth and fruit production, even under stress conditions, and controlled ALS by over 50%.

Summary: The effect of pre-flowering application of ASM on defence gene expression in kiwifruit plants is known, however, the effect of postharvest ASM on defence gene expression is unknown. In this study, the expression of eight defence marker genes was measured in kiwifruit vine leaves after postharvest treatment with ASM and/or copper.
