Summary: Rice is an important food crop, but its production is threatened by various diseases. Breeding resistant rice varieties, especially those with broad-spectrum disease resistance genes, is an effective method to control pathogens. Researchers have focused on identifying rice broad-spectrum disease resistance genes in recent years, providing new genetic resources for breeding resistant rice varieties.

Summary: This study addresses the critical need for new antibacterial drugs in the face of bacterial multidrug resistance resulting from antibiotic overuse. It highlights the significance of antimicrobial peptides as essential components of innate immunity in animals and plants, which have been proven effective against multidrug-resistant bacteria and are difficult to develop resistance against. This study successfully synthesizes a broad-spectrum antibacterial peptide, BsR1, with strong inhibitory activities against various Gram-positive and Gram-negative bacteria. BsR1 demonstrates favorable stability and a mode of action that damages bacterial cell membranes, leading to cell death. It also exhibits biological safety and shows potential in enhancing disease resistance in rice. This research offers a novel approach and potential medication for antibacterial drug development, presenting a valuable tool in combating pathogenic microorganisms, particularly in plants.

Summary: Sclerotinia sclerotiorum is a pathogenic fungus with a wide host range and preference for dicotyledonous plants. Plant resistance to this pathogen is highly complex, posing challenges for resistance breeding. Therefore, studying the evolutionary and molecular features of this pathogen is of great importance.

Summary: Plant pathogens with a broad host range are more commercially attractive for bioherbicides due to wider market potential. However, the perceived risk to nontarget plants is a barrier to their adoption. Two approaches to managing this risk are considered: safety zones and withholding periods, and the use of weed-specific isolates. These approaches can improve the adoption of bioherbicides for weed control.

Summary: CRISPR drive is a powerful tool for genetic manipulation and has potential applications in controlling pests and diseases in both animals and plants. In plant breeding, CRISPR drive can be used to disrupt susceptibility genes and develop pathogen-resistant cultivars. Further research and improvement are needed to fully utilize this technology and obtain homozygous mutant lines.

Summary: Host plant resistance has been a key breeding target in the CSIRO cotton breeding program and has led to the development of cultivars resistant to Bacterial blight, Verticillium wilt, Fusarium wilt, and Cotton bunchy top. However, emerging threats and secondary pests pose challenges to Australian cotton production systems. The adoption of tools and breeding methods, along with the utilization of resistance sources, will be crucial for future cotton breeding.

Summary: Nanoemulsified essential oils can enhance plant resistance against Botrytis cinerea and effectively control pathogen infections. RNA-seq analysis shows that successful treatments can enhance plant disease resistance by upregulating autophagy, ROS scavenging, and activating the jasmonic acid signaling pathway.

Summary: Rice production needs to be sustained in the face of increasing disease outbreaks caused by changing climatic conditions. Rice blast, a serious fungal disease caused by Magnaportheoryzae, is considered a major threat to global rice production. Developing durable, resistant varieties through breeding and biotechnological methods is a sustainable and effective approach to counter the outbreaks of rice blasts.

Summary: Viruses interact with plants through RNA-silencing mechanisms and the innate immune system. The activation of pattern-triggered immunity (PTI) by viruses in plant cells can be counteracted by viral suppression. Intracellular immune receptors may detect viral Avirulence proteins to trigger effector-triggered immunity (ETI).

Summary: Genome editing technologies have revolutionized plant biology, offering solutions to challenges in plant architecture, food security, nutrient content, environmental adaptation, disease resistance, and production of plant-based materials. The efficiency of site-specific genome editing in plants, with a powerful toolbox of molecular scissors, allows for tailored approaches to plant breeding strategies. The synergies of genome editing with other technological platforms are leading to an exciting era of post-genomic plant research and production, demonstrating the importance of science, technology, and tools in meeting current and future challenges in agriculture.

Summary: This study evaluated pathogenic variation in P. medicaginis populations and found differences in aggressiveness of isolates using different phenotyping methods. The study also showed that phenotyping methods interact with both isolate and host genotype reactions. The cup-based root inoculation method showed promise as a non-field-based phenotyping method, with significant correlations with genotype-isolate rankings in the field experiment for several disease parameters.

Summary: Multiline and cultivar mixtures are effective methods for controlling plant diseases in agroecology. This study developed an epidemiological model to explore the impact of host mixtures on disease prevalence caused by polymorphic pathogen populations. The findings suggest that a large amount of resistance genes or the priming mechanism are needed to achieve low disease prevalence.
