Summary: This study introduces a modified mu RAMOS device for analyzing plant seedlings. The device was used to validate the suitability for identifying novel PrimACs in Arabidopsis thaliana, with the results showing Tyr020 as a likely PrimAC. The difference in OTR between primed and unprimed plants after elicitation with flg22 suggests that the mu RAMOS device can be reliably used for screening PrimACs in plant seedlings.

Summary: Herbivore-induced plant volatiles play a crucial role in regulating defenses in undamaged neighboring plants. Understanding the mechanisms of plant volatile uptake, perception, and translation into defense signaling pathways is essential. Various molecular processes, such as membrane-associated and intracellular receptors, as well as mitogen-activated protein kinases (MAPKs), WRKY transcription factors, and jasmonates, are involved in translating volatiles into defense priming and induction. The diverse molecular processes in volatile signaling result in spatiotemporal and ontogenetic variation in plant responsiveness to volatiles, which has significant implications for plant-environment interactions.

Summary: Plant diseases caused by pathogenic microorganisms have a significant impact on agriculture. The use of chemical pesticides and antimicrobials has adverse effects on human health and the environment, and contributes to the emergence of antibiotic resistance among phytopathogens. Therefore, it is crucial to explore natural alternatives. The Streptomyces genus of bacteria has been extensively researched for its ability to produce diverse antimicrobial compounds, making it a potential biological control agent against plant pathogens.

Summary: We provide a comprehensive view of plant-biotic-phosphate interactions highlighting the modulation of plant immunity by phosphate levels, and outline key players, their crosstalk, and the underlying molecular mechanisms. Phosphorus (P) deficiency stress in combination with biotic stress(es) severely impacts crop yield. This nutrient-dependent response is highly regulated by the phosphate starvation response (PSR) mediated by the master regulator, PHR1, and its homolog, PHL. It is interesting to note that Pi status (deficiency/sufficiency) has a varying response (positive/negative) to different biotic encounters (beneficial microbes/opportunistic pathogens/insect herbivory) through a coupled PSR-PHR1 immune system. This also involves crosstalk among multiple players including transcription factors, defense hormones, miRNAs, and Pi transporters, among others influencing the plant-biotic-phosphate interactions. We propose strategies to utilize this information to improve crop resilience to Pi deficiency in combination with biotic stresses.

Summary: Plants have a sophisticated immune system that coordinates with other biological and metabolic pathways to defend against biotic stresses. Photorespiration, a byproduct pathway of photosynthesis, is involved in defense responses and impacts the homeostasis of hydrogen peroxide, a crucial signaling molecule in plant immunity. Understanding the relationship between plant immunity and photorespiration is important for crop engineering to enhance photosynthesis without compromising plant immunity.

Summary: In this study, the genome of Acidithiobacillus ferrooxidans strain TFBk was analyzed to identify genes potentially important in the bioleaching process of arsenopyrite concentrate. The study found genes related to arsenic resistance, utilization of C-1 compounds, and oxidative stress resistance. The results showed that the addition of formate increased both the biomass yield and the bioleaching rate of the strain. Furthermore, the effect of increasing redox potential by adding sodium persulfate on arsenopyrite concentrate bioleaching was investigated. The addition of 0.1% sodium persulfate stimulated strain growth and increased the rate of concentrate bioleaching.
