Article Synopsis
- * Using a large population of 1629 plants, researchers pinpointed the YR30 locus down to a 0.52-centiMorgan interval, highlighting its potential durability as an adult plant resistance (APR) gene.
- * Analysis of haplotypes revealed that the YR30_h6 variant exhibited greater resistance to stripe rust and resulted in a 32.94% higher grain yield under rust-affected conditions compared to other haplot
Molecular diagnostics for crop diseases can guide the precise application of pesticides, thereby reducing pesticide usage while improving crop yield, but tools are lacking. Here, we report an in-field molecular diagnostic tool that uses a cheap colorimetric paper and a smartphone, allowing multiplexed, low-cost, rapid detection of crop pathogens. Rapid nucleic acid amplification-free detection of pathogenic RNA is achieved by combining toehold-mediated strand displacement with a metal ion-mediated urease catalysis reaction.

is a soilborne fungus that can cause sharp eyespot in wheat, resulting in massive yield losses found in many countries. Due to the lack of resistant cultivars, fungicides have been widely used to control this pathogen. However, chemical control is not environmentally friendly and is costly.

- Fusarium head blight (FHB) in wheat reduces crop yield and introduces harmful mycotoxins, necessitating early and accurate detection methods.
- A new CRISPR-Cas12a-based nucleic acid assay offers a rapid diagnostic solution by specifically targeting genetic sequences associated with the disease, achieving detection levels as low as 1 fg/μL of DNA.
- This assay distinguishes FHB from other fungi using a dual recognition process, enhancing the applicability of CRISPR technology in diagnosing crop diseases.
