“…Additionally, proteins linked to PTI and ABA synthesis were found to be upregulated in response to R. solani infection, indicating that the resistance mechanism was mediated by PTI, with ABA acting as a signaling molecule. These ndings corroborate similar results reported by previous researchers in various host-pathogen systems 49,50,51 .…”

Sheath blight (ShB) disease, instigated by Rhizoctonia solani Kuhn, inflicts a significant economic threat to rice production, trailing closely behind blast. Acknowledging the limited understanding of ShB resistance proteomics in highly resistant germplasm, our study aimed to unravel the proteomic intricacies underlying the interaction between resistant landrace Nizam Shait and R. solani. Utilizing Nizam Shait and BPT-5204 as representatives of ShB resistance and susceptibility, a comparative proteome analysis was performed using Orbitrap-Fusion mass spectrometry. The analysis unveiled 5133 differentially expressed proteins, with 118 significantly upregulated and 172 significantly downregulated at a0.05 p-value. Notably, the 14-3-3 like protein GF-E exhibited the highest upregulation, indicating its pivotal role in the brassinosteroid signaling pathway and defense modulation. Proteins associated with systemic acquired resistance, R gene-mediated resistance, and cell death were downregulated, while those linked to jasmonic acid-induced systemic resistance (JA-ISR) showed notable upregulation, confirming ISR induction in response to ShB infection. Key signaling pathways involved in ShB resistance in Nizam Shait encompassed PTI via JA-ISR, cell wall strengthening, and brassinosteroid and abscisic acid-mediated resistance. Validation of the proteome data through qRT-PCR corroborated the findings, underscoring the significance of this research for future proteome assisted breeding efforts aimed at developing ShB resistant rice varieties.

“…Among these factors, many protein kinases play an important role in stress signal perception and transduction [24]. The level of ABA in plants is enhanced by 9-cis-epoxycarotenoid dioxygenase (NCED), which in turn triggers the activation of genes involved in plant response to drought stress, leading to the initiation of physiological processes such as stomatal closure [25,26]. Furthermore, the ABA-responsive binding factor (ABF) is involved in the expression of genes that are responsive to drought stress; thus, it preserves the plant's ability to resist drought stress [27].…”

Plant roots play crucial roles in their response to drought conditions. However, the molecular responses in soybean roots to drought stress remain unclear. We investigated the alterations in the protein expression in the roots of a drought-resistant soybean cultivar ‘Jiyu 47’ during the seedling phase based on tandem mass tag (TMT) proteomics analysis. The results revealed significant variations in the expression of the proteins involved in several metabolic pathways in soybean roots, including sucrose metabolism, abscisic acid (ABA) metabolism, and the ATP-binding cassette (ABC) transporter pathway. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed a coordinated expression pattern of the proteins involved in the various cellular pathways responding to drought stress in soybean. The increased production of sucrose and betaine enhanced the inhibition of the damage caused by reactive oxygen species (ROS) and the tolerance of drought stress. The results of the physiological variations showed that sucrose metabolism, ABA metabolic mechanism, and the ABC transporter pathways played an important role in the antioxidant defense system in response to drought stress in soybean roots. The results of quantitative real-time PCR revealed the up-regulated expression of three genes (i.e., GmPYR1, GmHO-1, and GmSOD) involved in ABA biosynthesis and the signaling pathway. This study provides novel insights into the comprehension of the molecular pathways regulating the soybean root response to drought stress.
