Discovering genetic loci associated with rate of vegetative index gain using UAV-based phenomics in spring wheat

This study utilized UAV-based phenomics to quantify the rate of vegetation index gain in 196 spring wheat cultivars, identifying two stable genetic loci on chromosomes 1B and 5D that are positively associated with yield and have been increasingly selected during modern breeding, thereby providing KASP markers to facilitate high-throughput genetic dissection of canopy dynamics and yield formation.

Wild rice Oryza rufipogon outperforms cultivated rice in stimulating beneficial bacterial endophytes.

This study demonstrates that wild rice (Oryza rufipogon) more effectively stimulates beneficial bacterial endophytes than cultivated varieties, suggesting that reintroducing lost wild traits could enhance sustainable rice productivity through improved plant-microbe interactions.

A conserved structural logic underlies sensor-helper NLR communication in the NRC immune receptor network

This study utilizes AlphaFold 3 predictions and experimental validation to identify conserved structural interfaces between sensor and helper NLRs in the NRC network, demonstrating that these interactions follow an activation-and-release mechanism and can be bioengineered to expand disease resistance in crops.

Colletotrichum higginsianum effector ChEC108 binds a plasmodesmal HMA protein and elicits plant defence

The fungal effector ChEC108 from *Colletotrichum higginsianum* binds the plasmodesmal protein HIPP6 to trigger plasmodesmal closure and activate plant defense responses, thereby restricting its own cell-to-cell mobility and limiting fungal infection.

Evolutionary diversification of the SymRK receptor family in land plants

This study characterizes the evolutionary diversification and transcriptional regulation of the SymRK receptor family and its homologs across land plants, revealing a contrast between conserved, functionally critical genes and rapidly expanding, tandemly duplicated clusters that drive species-specific adaptations and diverse responses to biotic stimuli.

A Fungal Natural Product that Inhibits Plant Cellulose Biosynthesis by disrupting Cellulose Synthase Complexes

This study identifies the fungal natural product 8-methyldichlorodiaporthin (MDD) as a novel, broad-spectrum cellulose biosynthesis inhibitor that targets CESA1 to disrupt cellulose synthase complexes, and demonstrates that stacking specific CESA mutations can generate multi-drug resistant plants for potential applications in weed management and crop biotechnology.
