Genome editing of a rice CDP-DAG synthase confers multipathogen resistance

Gan Sha et al.

Summary: The discovery and application of genome editing has provided efficient tools for precise engineering of crop genomes, leading to a new era in plant breeding. In this study, researchers demonstrated the power of genome editing in engineering broad-spectrum disease resistance in rice. They identified a gene named RBL1, which, when mutated, resulted in broad-spectrum disease resistance but also caused a significant decrease in yield.

Genome-edited powdery mildew resistance in wheat without growth penalties

Shengnan Li et al.

Summary: Disruption of susceptibility genes in crops can confer disease resistance, but often leads to undesired effects. This study identifies a mutant wheat variety with a targeted deletion in a specific gene that retains crop growth and yields while conferring robust resistance to powdery mildew.

NLRs guard metabolism to coordinate pattern- and effector-triggered immunity

Keran Zhai et al.

Summary: This study identifies the deubiquitinase PICI1 as a key player in regulating PTI and ETI in rice, promoting the production of defense metabolites by activating methionine synthetase, and ensuring coordination between PTI and ETI. NLRB receptors such as PigmR protect PICI1 from effector-mediated degradation in the plant immune system, contributing to broad-spectrum resistance.

Ca2+ sensor-mediated ROS scavenging suppresses rice immunity and is exploited by a fungal effector

Mingjun Gao et al.

Summary: The discovery of a conserved immune suppression network in cereals centered on the Ca2+-sensor ROD1 is significant in understanding how plants fine-tune immune homeostasis. ROD1 promotes reactive oxygen species scavenging and its disruption confers resistance to multiple pathogens. The fungal effector AvrPiz-t structurally mimics ROD1 to suppress host immunity and promote virulence, revealing a molecular framework for breeding disease-resistant, high-yield crops.

A monocot-specific hydroxycinnamoylputrescine gene cluster contributes to immunity and cell death in rice

Hong Fang et al.

Summary: The study identified an HP biosynthetic gene cluster in rice consisting of OsODC, OsPHT3, and OsPHT4, which play a role in PAs synthesis and plant resistance to biotic stress. Overexpression of OsPHT3 or OsPHT4 leads to HP accumulation and cell death, while enhancing resistance against fungal pathogens.
