The immune signal SA triggers metabolic changes to activate SnRK1 while inhibiting TOR. These central metabolic kinases antagonistically phosphorylate the key immune regulator NPR1, thereby coupling cellular metabolic state to systemic acquired resistance.

In Drosophila, the protein Lsp2, which is induced by dietary essential amino acids, is a key physiological effector of mTORC1, and mutant flies that lack the Lsp2 gene exhibit reduced translation of TOP mRNAs and improved longevity.

Centromeres in Arabidopsis thaliana evolve through frequent insertions and deletions of repeat units and increased rates of point mutations driven by homology-directed repair, a mutation spectrum that...

Summary: This study presents a live-imaging platform for tracking individual plant protoplasts in culture, enabling analysis of cellular processes, signaling dynamics and developmental transitions.

The apoplast is a primary location for interactions between plants and invasive pathogens and is the site where many pathogen-secreted effectors are perceived by cell surface immune receptors to activ...

A mechanistic basis for how the hormone salicylic acid promotes transcriptional activation during plant immune responses is described.

Welcome! Our research focuses on the evolutionary process at the molecular level. In particular, we investigate how a mixture of natural selection and non-adaptive forces create and maintain the amazi...

Plants and other photosynthetic organisms interact with their environment and surrounding microbiota through specialized associations. A global core microbiota has been proposed at high taxonomic levels, such as the order level. However, it remains unclear which environmental factors and how microbe-microbe interactions drive variation of this core microbiota at lower taxonomic resolution. Here, we leveraged the environmental diversity of 141 sites across the southwest of France to characterize algal populations, and their associated bacterial and fungal microbiota. We then performed a meta-analysis, combining these data with published datasets to formally identify the global core microbiota of terrestrial photosynthetic organisms, which comprises seven bacterial and five fungal orders. We next investigated diversity within this core microbiota and the environmental drivers shaping site-specific community composition. While environmental factors have a low impact on the total relative abundance of core orders, the core microbiota at the ASV-level is impacted by climatic factors, edaphic factors, and plant community descriptors. Using interaction network analysis, we finally explored how microbe-microbe interactions contribute to the assembly of stable core communities. Our results show that core ASVs occupy central positions in algal-associated microbial networks and that distinct core orders drive site-specific variation in core microbiota structure. Together, these findings highlight the importance of both environmental context and microbial interactions in shaping the composition and stability of the core microbiota associated with photosynthetic organisms. ### Competing Interest Statement The authors have declared no competing interest.
