TL;DR

The identified biomarker metabolites, particularly those linked to the shikimate and GS/GOGAT pathways, represent promising candidates for metabolite-assisted breeding and targeted crop protection strategies against early blight in potato.

Host Metabolites Directly Suppress Fusarium Mycotoxin Biosynthesis and Enable Integrated Control of Rice Spikelet Rot Disease.

Rice spikelet rot disease (RSRD) threatens food safety by contaminating grains with diverse mycotoxins. This study revealed a climate-driven shift in pathogen dominance from Alternaria spp. to Fusarium spp., determining associated toxin chemotypes. Untargeted LC-MS metabolomics of wheat infected by Fusarium graminearum...

Metabolic Analysis Reveals Alkaloid-Mediated Resistance of Tobacco against Ralstonia solanacearum.

Tobacco (Nicotiana tabacum L.) is a globally important industrial crop, yet its productivity is severely threatened by bacterial wilt caused by R. solanacearum. In this study, integrative metabolomics and transcriptomics profiling of tobacco plants infected with R. solanacearum identified 571 differentially accumulated...

Long Non-Coding RNA StlincPRI Enhances Resistance to Phytophthora infestans by Regulating Reactive Oxygen Species Homeostasis

Potato (Solanum tuberosum) is the fourth-largest food crop worldwide. However, late blight, caused by oomycete Phytophthora infestans, poses a major threat to global production. Although long non-coding RNAs (lncRNAs) have emerged as key regulators of plant immune responses, their role in potato immune response remains...

Spatiotemporal Dissection of the Infection Response to Bacterial Soft Rot in Non-heading Chinese cabbage.

Bacterial soft rot caused by Pectobacterium brasiliense (Pbr) leads to substantial yield losses in cruciferous vegetables, including non-heading Chinese cabbage (pak choi, Brassica rapa subsp. chinensis). This study employed an integrated physiological and multi-tissue transcriptomic approach to decipher the infection...

Fusaric acid as a central hub of virulence: Reprogramming host physiology during Fusarium infection.

Fusarium spp. include major soilborne pathogens that cause vascular wilt diseases in diverse crops. Fusaric acid (FA) is a non-host-specific toxin produced by some Fusarium species and contributes to virulence in several, but not all, host-pathogen systems. Traditionally, FA has been regarded as a broad-spectrum phytot...

From loci to mechanisms: wheat autoimmunity as a window into plant immune activation.

Wheat (Triticum aestivum L.) is a major staple crop, and developing broad-spectrum resistance to multiple fungal pathogens is essential for sustainable production. Wheat autoimmunity (WAI) mutants represent genetic resources that spontaneously activate immune responses under non-stress conditions, exhibiting lesion-mim...
