Transgenic Lines

In Arabidopsis, both pathogen invasion and benzothiadiazole (BTH) treatment activate the nonexpresser of pathogenesis-related genes 1 (NPR1)-mediated systemic acquired resistance, which provides broad-spectrum disease resistance to secondary pathogen infection. However, the BTH-induced resistance in Triticeae crops of wheat and barley seems to be accomplished through an NPR1-independent pathway. In the current investigation, we applied transcriptome analysis on barley transgenic lines overexpressing wheat wNPR1 (wNPR1-OE) and knocking down barley HvNPR1 (HvNPR1-Kd) to reveal the role of NPR1 during the BTH-induced resistance. Most of the previously designated barley chemical-induced (BCI) genes were upregulated in an NPR1-independent manner, whereas the expression levels of several pathogenesis-related (PR) genes were elevated upon BTH treatment only in wNPR1-OE. Two barley WRKY transcription factors, HvWRKY6 and HvWRKY70, were predicted and further validated as key regulators shared by the BTH-induced resistance and the NPR1-mediated acquired resistance. Wheat transgenic lines overexpressing HvWRKY6 and HvWRKY70 showed different degrees of enhanced resistance to Puccinia striiformis f. sp. tritici pathotype CYR32 and Blumeria graminis f. sp. tritici pathotype E20. In conclusion, the transcriptional changes of BTH-induced resistance in barley were initially profiled, and the identified key regulators would be valuable resources for the genetic improvement of broad-spectrum disease resistance in wheat.

Molecular Aspects

This mini-review points to the usefulness of the pea–Fusarium solani interaction in researching the biochemical and molecular aspects of the nonhost resistance components of peas. This interaction has been researched to evaluate the resistance roles of the phytoalexin, pisatin, the cuticle barrier, and the activation of the nonhost resistance response. Concurrently, evaluations of associated signaling processes and the tools possessed by the pathogen to contend with host obstacles were included. The properties of some pathogenesis-related genes of pea and their regulation and contribution to resistance are discussed. A proposed action of two biotic elicitors on both chromatin conformation and the architectural transcription factor, HMG A, is presented and includes time lines of events within the host immune response.
