AI Article Synopsis
- - The interaction between plants and fungi is complex and not fully understood, particularly how fungal endophytes successfully colonize plants without causing harm.
- - Small RNAs, specifically miRNAs, play a crucial role in regulating these biotic interactions, and this study focused on identifying them in the model plant Arabidopsis thaliana.
- - The research identified 15 differentially expressed miRNAs, with ath-miRNA398b being particularly important, and confirmed its regulatory role along with target genes through various analysis methods, highlighting the significant role of miRNAs in plant-fungal interactions.
Article Abstract
Plant and fungus interaction is a complex process involving many molecular factors determining the nature of relationship. The enigmatic methodology by which fungal endophytes are able to colonise a plant harmoniously is still inexplicable. Small RNAs have been identified as major regulatory elements under various biotic interactions. However, their role in endophytic plant-fungal interactions remain to be elucidated. Therefore, transcript expression data available on Gene Expression Omnibus for Arabidopsis thaliana was utilised for miRNAs identification under endophytism. The analysis predicted 15 miRNAs with differential expression of which the ath-miRNA398b modulation was significant. Application of psRNAtarget, C-mii, pmiREN, and TarDB provided a pool of 357 target genes for these miRNAs. Protein-protein interaction analysis identified major hub proteins, including BTB/POZ domain-containing protein, beta-Xylosidase-2 (AtBXL2), and Copper/Zinc Superoxide Dismutase-2 (AtSOD2). The quantitative real-time PCR validated the computational prediction and expression for selected target genes AtSOD2, AtBXL2, and AtRCA along with ath-miRNA398b under endophytism. Overall, results indicate that miRNAs have a significant role in regulating Arabidopsis thaliana-endophytic fungal interaction.

The SWItch/Sucrose Non-Fermenting (SWI/SNF) complexes are evolutionarily conserved, ATP-dependent chromatin remodelers crucial for multiple nuclear functions in eukaryotes. Recently, plant BCL-DOMAIN HOMOLOG (BDH) proteins were identified as shared subunits of all plant SWI/SNF complexes, significantly impacting chromatin accessibility and various developmental processes in Arabidopsis. In this study, we performed a comprehensive characterization of mutants, revealing the role of BDH in hypocotyl cell elongation.

The vacuole is an important site for RNA degradation. Autophagy delivers RNA to the vacuole, where the vacuolar T2 RNase Ribonuclease 2 (RNS2) plays a major role in RNA catabolism. The presumed products of RNS2 activity are 3'-nucleoside monophosphates (3'-NMPs).

In plants, cytoskeletal proteins assemble into dynamic polymers that play numerous roles in diverse fundamental cellular processes, including endocytosis, vesicle trafficking, and the spatial distribution of organelles and protein complexes. Plant elicitor peptides (Peps) are damage/danger-associated molecular patterns (DAMPs) that are perceived by the receptor-like kinases PEP RECEPTOR 1 (PEPR1) and PEPR2 to enhance innate immunity and inhibit root growth in Arabidopsis (Arabidopsis thaliana). To date, however, there is little evidence that the actin cytoskeleton of the host cell participates in DAMP-induced innate immunity.

Jasmonic acid (JA), ethylene (ET) and salicylic acid (SA) are the three major phytohormones coordinating plant defense responses, and all three are implicated in the defense against the fungal pathogen Fusarium oxysporum. However, their distinct modes of action and possible interactions remain unknown, in part because all spatial information on their activity is lacking. Here, we set out to probe this spatial aspect of plant immunity by using live-microscopy with newly developed fluorescence-based transcriptional reporter lines.
