Summary: The rhizosphere is a niche surrounding plant roots, where root volatile organic compounds (rVOCs) can influence the composition and growth dynamics of soil biofilms. Methyl jasmonate (MeJA) is an rVOCs signal that triggers changes in biofilm and microbiome. This cross-kingdom signaling expands the influence of plants in the rhizosphere.

Summary: Specialised metabolites produced during plant-fungal associations play crucial roles in defining and establishing symbiotic relationships. However, they are often overlooked in studying plant-microbe interactions. This study investigated how the specialised metabolism of tomato plants is regulated during a mutualistic symbiotic association with the root endophyte Serendipita indica. The results showed that the presence of S. indica induced the expression of genes involved in the biosynthesis of specific compounds in both roots and leaves, while the expression levels of other pathways were lower.

Summary: In this study, we investigated the drought mitigating effects of the beneficial fungus Piriformospora indica on rice plants under varying moisture stress. Our results showed that under extremely severe stress, colonized plants exhibited significant improvements in growth and yield. Colonized plants had deeper root depth and higher root volume under severe stress, which contributed to better performance in terms of growth and yield. Colonization by the beneficial fungus also increased lateral root production, resulting in a greater area for water and nutrient absorption. Additionally, colonization improved phosphorus acquisition and water use efficiency of the plants.

Summary: Currently, there is limited information available on lncRNAs in barley and their response to P. indica colonization. This study found that P. indica colonization resulted in fast development and branching of barley roots. Through RNA-seq and bioinformatic analysis, it was discovered that numerous lncRNAs were differentially expressed in response to P. indica, and many of these lncRNAs showed positive correlation with mRNA expression. Further analysis revealed the potential involvement of certain lncRNAs in gene transcription regulation and cell cycle regulation.

Summary: Azospirillum baldaniorum is a plant growth-promoting rhizobacterium that can fix nitrogen, synthesize phytohormones, and induce plant defenses. It forms biofilms, regulated by the second messenger c-di-GMP, which promote bacteria-plant interactions. Understanding the role of c-di-GMP in colonization of plant roots will help in designing better biotechnological strategies.

Summary: In this study, the functional characterization of two Na+/H+ antiporters, SiNHA1 and SiNHX1, in Serendipita indica was conducted to investigate their potential role in saline tolerance. These antiporters, along with previously characterized Na+ efflux systems, may help to remove excess sodium from the cytosol of S. indica under saline stress. Additionally, a comprehensive RNA-seq approach revealed the transportome of S. indica, and it was found that SiENA5 is a major salt-responsive gene in both free-living and symbiotic conditions.

Summary: Phosphate availability significantly influences the symbiotic interaction between Arabidopsis and Trichoderma harzianum, leading to fungal colonization of the host plant under low phosphate conditions. The fungus alleviates the plant's phosphate starvation response initially but ultimately imposes stress on the host by altering sugar transporter genes.
