Here, we demonstrate that the sorghum bHLH transcription factor SbbHLH168 is a central regulator of salt-stress tolerance. SbbHLH168 is nuclear-localized, constitutively expressed in all organs and rapidly up-regulated by NaCl. Overexpression of SbbHLH168 in either Arabidopsis or sorghum conferred markedly higher biomass retention, longer roots, lower relative electrical conductivity, less accumulation of superoxide and H₂O₂, and lower Na⁺/K⁺ ratio through decreased Na⁺ accumulation under salt stress, whereas VIGS silent groups displayed the opposite phenotype. qRT-PCR and biochemical assays demonstrated that SbbHLH168 up-regulates key lignin-biosynthetic genes (SbC4H, SbF5H, SbCOMT1) and increases root lignin content under salt stress, thereby reinforcing cell-wall integrity and limiting ion leakage. Furthermore, yeast two-hybrid and BiFC assays confirmed that SbbHLH168 interacts with SbbHLH35 in the nucleus, indicating that SbbHLH168's functional activity depends on heterodimerization with SbbHLH35.

Raffinose is synthesized by RAFFINOSE SYNTHASE (RAFS) from galactinol and sucrose, whereas stachyose can be produced by STACHYOSE SYNTHASE (STS) from galactinol and raffinose. While Arabidopsis possesses functional RAFS and STS genes and produces both raffinose and stachyose, maize lacks both a functional STS gene and endogenous stachyose. Here, we show that Arabidopsis STACHYOSE SYNTHASE (AtSTS) is induced by heat stress, and its overexpression and subsequent stachyose accumulation enhance heat tolerance. To extend the RFOs pathway in maize, we introduced the AtSTS expression cassette into the maize genome. The resulting transgenic maize lines accumulated stachyose and exhibited improved heat tolerance. Under heat stress, stachyose amounts in these lines increased significantly, likely due to the induction of endogenous ZmRAFS and subsequent protein and raffinose production, the latter serving as the STS substrate. Compared with wild-type controls, transgenic maize seedlings showed reduced leaf damage, higher survival, and lower ion leakage under high-temperature conditions. The application of exogenous stachyose similarly improved heat tolerance in wild-type maize, providing further evidence of its protective function. Moreover, AtSTS overexpression reduced reactive oxygen species (ROS) accumulation, indicating that stachyose helps mitigate oxidative damage.

Effectors, as one class of weapons of phytopathogens, help pathogens infect their hosts by disturbing plant immunity. In this study, we identified a secreted effector, FpECIR, which has no functional domains, suppresses INF1-triggered cell death in Nicotiana benthamiana. Once translocated into wheat cells, FpECIR (without signal peptide) interacts with TaPLATZ2B, and silencing TaPLATZ2B and its alleles makes wheat more susceptible to F. pseudograminearum. Deletion of residues 29-35 of FpECIR disrupted its interaction with TaPLATZ2B, and eliminated its ability to suppress INF1-induced cell death. The pathogenicity of deletion mutants ΔFpecir on wheat coleoptiles was significantly reduced. Analysis of transcriptome data showed that infection with the ΔFpecir strain triggered the upregulation of defense-related genes in wheat coleoptiles, many of which were functionally enriched in hormone signaling pathways. qRT-PCR results revealed that FpECIR suppressed the expression of TaPLATZ2B and of genes related to ethylene signaling pathway. Furthermore, EMSA experiment result proved that FpECIR can inhibit the ability of TaPLATZ2B binding with the promoter region of ethylene response factors (TaERF020L). Suppressing the transcription levels of genes related to ethylene biosynthesis made the wheats more susceptible to FCR. Overall, the results showed that FpECIR plays an important role in the pathogenicity of F. pseudograminearum, and that the integrity of FpECIR is necessary for its interaction with TaPLATZ2B and for its suppression of INF1-induced cell death.

RTP1 negatively modulates resistance to P. parasitica via ER stress and cell death regulation, yet its downstream coordinators remain unclear.

Mechanistically, RTP1 interacts with BI-1 and reduces its protein accumulation through a proteasome-independent pathway, thereby antagonizing BI-1 function. Conversely, activated forms of ER stress transducers bZIP60 and bZIP28 bind and co-activate the BI-1 promoter.

Moreover, CrP suppressed heat stress-induced increases in serum corticosterone and lipopolysaccharide levels while enhancing intestinal glutathione peroxidase activity.

Analysis of 16S rRNA sequencing revealed distinct differences in microbial composition and potential functional shifts among groups.

Through phenotypic screening, RNA sequencing, and a Weighted Gene Co-expression Network Analysis (WGCNA) we demonstrated that Trichoderma pre-treatment significantly mitigates FW symptoms and orchestrates a robust defense response in melon roots.
