Summary: Polyamines are small aliphatic polycations found in all living organisms. This study investigates the regulation of polyamine metabolism and their role in plant defense response. The researchers found that putrescine biosynthesis is stimulated by Pseudomonas syringae pv. tomato DC3000 through coronatine perception and jasmonic acid signaling. On the other hand, spermine deficiency leads to enhanced disease resistance and ER stress signaling in response to Pst DC3000. These findings provide evidence for the integration of polyamine metabolism in defense responses mediated by jasmonic acid and salicylic acid.

Summary: Mild heat stress affects the development of tomato plants, the defense mechanisms against Pseudomonas syringae pv. tomato, and the growth and virulence machinery of bacteria. Tomato plants are able to adapt to heat stress and show higher thermotolerance, while producing certain metabolites to cope with this environment. Under high temperatures, plants are less susceptible to Pseudomonas syringae pv. tomato infection, and the increased temperature negatively affects bacterial infectivity.

Summary: This study aimed to improve the immune defense of common beans against halo blight disease by using plant-based preparations made from industrial waste and wild plants. Two of the preparations (grapevine pomace and Urtica dioica) were found to promote the expression of defense-related genes and reduce the occurrence of the disease. Although the use of these preparations resulted in a decrease in yield parameters, it did not affect the final production.

Summary: This review discusses the spatiotemporal nature of gene regulation in plants, highlighting the ways in which plant tissues are time sensitive. It explores how the study of plant cell identity can reveal developmental trajectories, the evidence showing plant cell types maintain their own local time through tissue-specific regulation of the circadian clock, and what determines the speed of environmental signaling responses. The review sheds light on how these different scales of time-based responses can act with tissue and cell-type specificity to elicit changes in whole plant systems.

Summary: Opium poppy is an ancient medicinal plant with limited knowledge of its genetic diversity. This study used genotyping-by-sequencing to investigate the genetic diversity and population structure of a collection of poppy germplasm. The study identified five distinct subpopulations and found that accessions from the same country were grouped together within subpopulations. The study also identified diverse alkaloid profiles among the accessions. These results provide valuable resources for further genetic diversity analysis and genetic improvement of this important crop.

Summary: Elevated growth temperatures reduce crop productivity and yield losses. Modulating root traits to improve response to rising temperatures can generate new varieties better adapted to climate change. Our study identified altered root traits in Brassica napus in response to warm temperatures, resulting in an extended and deeper root system. This enhanced root growth improves root-soil interaction and increases the ability to explore soil areas. We found that changes in cell division and elongation rates, regulated by heat-shock stress response, drive root growth increases. Understanding this root response to warming temperatures can aid in improving crop yield under future climate scenarios.

Summary: Plants and phytophagous arthropods have coevolved in a battle for survival, with plants producing antiherbivore chemicals and herbivores adapting to their hosts. Cyanogenic glucosides are defense chemicals produced by cyanogenic plants, while the Brassicaceae family has evolved an alternative pathway to produce cyanohydrin. When a plant tissue is damaged, cyanogenic substrates come into contact with degrading enzymes, releasing toxic cyanide and derived compounds. This review focuses on the plant metabolic pathways linked to cyanogenesis and highlights its role as a defense mechanism against herbivores, discussing the potential of cyanogenesis-derived molecules for pest control strategies.

Summary: Different plant species use different jasmonates to activate a conserved signaling pathway in land plants, with JA-Ile being the ligand for COI1/JAZ receptor in angiosperms and dn-cis-OPDA, dn-iso-OPDA, and Delta(4)-dn-iso-OPDA acting as ligands in Marchantia polymorpha. OPDA and dn-OPDA are found in all tested land plants and charophyte algae, suggesting their importance as ancestral signaling molecules. JA-Ile biosynthesis emerged in lycophytes coinciding with the evolution of JAR1 function.

Summary: A library of all stereochemical isomers of coronatine was constructed to identify subtype-selective agonists for COI1-JAZ co-receptors in Arabidopsis thaliana and Solanum lycopersicum. The study highlights the challenge of dissecting the specific functions of receptor subtypes in gene families encoding plant hormone receptors. The identification of subtype-selective agonists is crucial for understanding the responses regulated by individual receptor subtypes.

Summary: The study identifies the molecular components controlled by the transcription factor ANAC017 in Arabidopsis, which integrates primary stress responses to mitochondrial dysfunction with whole plant growth. ANAC017 recruits a signaling cascade involving ethylene, auxin, and MAP kinase pathways. Ethylene signaling precedes auxin signaling in the mitochondrial stress response, and a large part of the transcriptional regulation is dependent on ETHYLENE-INSENSITIVE 3.

Summary: The interaction between fungi and plant roots has a significant impact on agriculture and ecosystems. Fusarium oxysporum, a cosmopolitan plant pathogen, can cause wilting disease in a wide range of crops and can also colonize the roots of other plants as endophytes. This study identified a set of candidate effectors in tomato roots and found that they play a conserved role in various fungi and plants.
