Transcriptional responses of Medicago truncatula upon sulfur deficiency stress and arbuscular mycorrhizal symbiosis

ABSTRACT: In this work we aimed to get a first overview on S-stress responses in leaf and root tissues of mycorrhized and non mycorrhized plants. Several hundred genes showed a significant different transcript accumulation. Their annotation and GO ID association allowed us to investigate the our data in order to identify biological processes and molecular functions preferentially affected, and to better understand in which terms the symbiotic relation avoid the plant to face deleterious S-deficiency effects.

Spatial Co-transcriptomics Reveals Discrete Stages of the Arbuscular Mycorrhizal Symbiosis II

Project description:The symbiotic interaction of plants with arbuscular mycorrhizal fungi (AM fungi) is ancient and widespread. Plants provide AM fungi with carbon in exchange for nutrients and water, making this interaction a prime target for crop improvement. However, plant-fungal interactions are restricted to a small subset of root cells, precluding the application of most conventional functional genomic techniques to study the molecular bases of these interactions. Here we used single-nucleus and spatial RNA sequencing to explore both M. truncatula and R. irregularis transcriptomes in AM symbiosis at cellular and spatial resolution. Integrated spatially-registered single-cell maps of interacting cells revealed major infected and uninfected plant root cell types. We observed that cortical cells exhibit distinct transcriptome profiles during different stages of colonization by AM fungi, indicating dynamic interplay between both organisms during establishment of the cellular interface enabling successful symbiosis. Our study provides insight into a symbiotic relationship of major agricultural and environmental importance and demonstrates a paradigm combining single-cell and spatial transcriptomics for the analysis of complex organismal interactions.

Analysis of gene expression in leaves of Medicago truncatula plants inoculated with arbuscular mycorrhizal fungi and plants fertilized with phosphate

Project description:Arbuscular mycorrhizas (AM) are the most common symbiotic associations between plant’s root compartment and fungi. They can provide both nutritional benefit (mostly inorganic phosphate) leading to improved growth and non-nutritional benefits including defense responses to environmental cues throughout the host plant, which in return delivers carbohydrates to the symbiont. However how transcriptional changes occurring in AM leaves differ from those induced by phosphate fertilization is poorly understood. We investigated systemic changes in the leaves of mycorrhized Medicago truncatula compared to non-mycorrhized control plants, and in phosphate fertilized plants compared to control plants.
