Non-pathogenic bacteria can largely contribute to plant health by mobilizing and supplying nutrients and by providing protection against pathogens and resistance to abiotic stresses. Yet, the number of GWAS reporting the genetic architecture of the response to individual members of the beneficial microbiota remains limited. In this study, we established a GWAS under field conditions to estimate the level of genetic variation and the underlying genetic architecture, among 162 accessions of Arabidopsis thaliana originating from 54 natural populations located south-west of France, in response to 13 strains of seven of the most abundant and prevalent non-pathogenic bacterial species isolated from the leaf compartment of A. thaliana in the same geographical region. Using a high-throughput phenotyping methodology to score vegetative growth-related traits, extensive genetic variation was detected within our local set of A. thaliana accessions in response to these leaf bacteria, both at the species and strain levels. The presence of crossing reaction norms among strains indicates that declaring a strain as a plant-growth promoting bacterium is highly dependent on the host genotype tested. In line with the strong genotype-by-genotype interactions, we detected a complex and highly flexible genetic architecture between the 13 strains. Finally, the candidate genes underlying the QTLs revealed a significant enrichment in several biological pathways, including cell, secondary metabolism, signalling and transport. Altogether, plant innate immunity appears as a significant source of natural genetic variation in plant-microbiota interactions and opens new avenues for better understanding the ecologically relevant molecular dialog during plant-microbiota interactions.

“…Other RNA‐binding proteins such as RBGD2/4 and GRP7, undergo phase separation and localise stress granules to promote heat stress tolerance (Xu et al, 2022; Zhu et al, 2022). The RNA‐binding protein phase separation is also involved in regulating transcription and alternative splicing (Zhang et al, 2020; Zhang et al, 2022). We summarised the RNA‐binding proteins involved in alternative splicing and translation control in response to environmental signals (Table 1).…”

Plants live in fixed locations and have evolved adaptation mechanisms that integrate multiple responses to various environmental signals. Among the different components of these response pathways, receptors/sensors represent nodes that recognise environmental signals. Additionally, RNA metabolism plays an essential role in the regulation of gene expression and protein synthesis. With the development of RNA biotechnology, recent advances have been made in determining the roles of RNA metabolism in response to different environmental signals—especially the roles of alternative splicing and translation. In this review, we discuss recent progress in research on how the environmental adaptation mechanisms in plants are affected at the posttranscriptional level. These findings improve our understanding of the mechanism through which plants adapt to environmental changes by regulating the posttranscriptional level and are conducive for breeding stress‐tolerant plants to cope with dynamic and rapidly changing environments.

“…In the model plant, Arabidopsis (Arabidopsis thaliana) LLPS is involved in, for example, the internal chloroplast cargo sorting, defence, diurnal rhythms, RNA processing, and environmental sensing by forming plant-specific condensates [6][7][8][9][10]. Furthermore, plants form stress granules and processing bodies to sense and respond to environmental stimuli [11][12][13].…”

Phase transitions of a SEC14-like condensate at Arabidopsis plasma membranes regulate root growth

Robust development can be modulated by local protein accumulation which is sometimes manifested as polarity patterns; yet, the mechanisms that lead to these patterns are largely unknown. Using the model plant Arabidopsis, we report that auxin-induced polar patterns can be reinforced by the phase transition of a SEC14-like lipid-binding protein at the plasma membrane. Using imaging, genetics, and in vitro reconstitutions, we show that the SEC14-like phase transition is promoted outside the stem cell root niche through its association with the caspase-like protease separase and conserved microtubule motors in a plasma membrane interface. Separase cleaves SEC14-like to promote its transition from liquid-like clusters to solid-like filaments. Filaments self-amplify and potentiate the robustness and maintenance of plasma membrane domains through associations with polar proteins. This work uncovers that robust cell patterns involve proteolysis-mediated phase transitions at unpreceded plasma membrane interfaces.
