Single-cell multi-omic characterization of the soybean root response to cyst nematode infection

ABSTRACT: Soybean cyst nematodes parasitize soybean roots by inducing the formation of multinucleate syncytia to feed and complete their life cycle. However, the molecular basis of syncytia initiation and development remains limited. Here, we generated an integrated single-nucleus RNA and chromatin accessibility profile of soybean roots from infected and uninfected plants. We profiled 56,448 high-quality nuclei and identified all major root cell types, including distinct subpopulations enriched with syncytial nuclei. Transcriptomic and chromatin accessibility analyses support their procambium cell signature that progresses through distinct stages associated with immune suppression, cell fusion, and endoreduplication. Integrative gene expression and transcription factor motif chromatin accessibility analyses identified CAMTA1, as a key transcriptional repressor of defense-related genes including receptor-like kinases (RLKs), whereas MYB, MYB-related, and E2F as transcriptional activators that coordinate cell wall remodeling, chromatin modification and DNA replication, respectively, across developmental trajectories. These findings provide mechanistic insights into host reprogramming during nematode parasitism and a foundational resource for engineering nematode-resistant soybean.

RNA-seq of soybean hairy roots in which GmMYB176 transcription factor was silenced or overexpressed

Project description:GmMYB176, an R1 MYB transcription factor regulates isoflavonoid biosynthesis in soybean. In the current experiment, GmMYB176 was silenced (GmMYB176-Si) or overexpressed (GmMYB176-OE) in soybean hairy roots and their effect on transcriptome was studied. RNA-Seq analyses of GmMYB176-Si and GmMYB176-OE along with control non-transformed soybean hairy roots revealed that alteration of gene expression of GmMYB176 affects gene regulation of hundreds of genes in soybean.

Identification of GmMYB176 interactome in soybean by Co-immunoprecipitation and LC-MS/MS

Project description:GmMYB176 is an R1 MYB transcription factor that regulates multiple genes in the isoflavonoid biosynthetic pathway thereby affecting isoflavonoid level in soybean roots. While GmMYB176 is important for isoflavonoid synthesis, it is not sufficient for the function and requires additional cofactor (s). The aim of this study was to identify GmMYB176 interactome for the regulation of isoflavonoid biosynthesis in soybean. GmMYB176 interactome was identified by Co-Immunoprecipitation using two YFP-tagged proteins baits, N’-GmMYB176-YFP-C’ and N’-YFP-GmMYB176-C’. GmMYB176 interacting proteins were identified by LC-MS/MS.

Proteomic Analysis of Soybean Root Tissues Before and After Inoculation with Heterodera glycines (Soybean Cyst Nematode)

Project description:This project aims to investigate the proteomic responses of roots from soybean (Glycine max) inoculated with soybean cyst nematode (Heterodera glycines, SCN) versus non-inoculated (pre-inoculation) soybean roots as control. Soybean root samples were collected from both groups and subjected to quantitative proteomic analysis using LC-MS/MS-based techniques, including protein extraction, tryptic digestion, and [specify quantification method, e.g., label-free quantification or TMT-based quantification]. Differentially expressed proteins were identified to characterize molecular mechanisms underlying soybean root responses to SCN infection.

Differences in syncytia formation by SARS-CoV-2 variants modify host chromatin accessibility and cellular senescence via TP53 [RNA-Seq]

Project description:COVID-19 remains a significant public health threat due to the ability of SARS-CoV-2 variants to evade the immune system and cause breakthrough infections. Although pathogenic coronaviruses such as SARS-CoV-2 and MERS-CoV lead to severe respiratory infections, how these viruses affect the chromatin proteomic composition upon infection remains largely uncharacterized. Here we used our recently developed integrative DNA And Protein Tagging (iDAPT) methodology to identify changes in host chromatin accessibility states and chromatin proteomic composition upon infection with pathogenic coronaviruses. SARS-CoV-2 infection induces TP53 stabilization on chromatin, which contributes to its host cytopathic effect. We mapped this TP53 stabilization to the SARS-CoV-2 spike and its propensity to form syncytia, a consequence of cell-cell fusion. Differences in SARS-CoV-2 spike variant-induced syncytia formation modify chromatin accessibility, cellular senescence, and inflammatory cytokine release via TP53. Our findings suggest that differences in syncytia formation alter senescence-associated inflammation, which varies among SARS-CoV-2 variants.

Dynamic changes in genome-wide histone methylation and gene expression of soybean roots in response to salt stress (RNA-seq dataset)

Project description:Soybean is an important economic crop for human diet, animal feeds and biodiesel due to high protein and oil content. Its productivity is significantly hampered by salt stress, which impairs plant growth and development by affecting gene expression, in part, through epigenetic modification of chromatin status. However, little is known about epigenetic regulation of stress response in soybean roots. Here, we used RNA-seq and ChIP-seq technologies to study the dynamics of genome-wide transcription and histone methylation patterns in soybean roots under salt stress. 8798 soybean genes changed their expression under salt stress treatment. Whole-genome ChIP-seq study of an epigenetic repressive mark, histone H3 lysine 27 trimethylation (H3K27me3), revealed the changes in H3K27me3 deposition during the response to salt stress. Unexpectedly, we found that most of the inactivation of genes under salt stress is strongly correlated with the de novo establishment of H3K27me3 in various parts of the promoter or coding regions where there is no H3K27me3 in control plants. In addition, the soybean histone modifiers were identified which may contribute to de novo histone methylation and gene silencing under salt stress. Thus, dynamic chromatin regulation, switch between active and inactive modes, occur at target loci in order to respond to salt stress in soybean. Our analysis demonstrates histone methylation modifications are correlated with the activation or inactivation of salt-inducible genes in soybean roots.
