This study characterizes the gut microbiota of the Guatemalan potato moth (Tecia solanivora), a major potato pest, to identify bacterial functions related to host fitness and insecticide detoxification. The research identifies potential biocontrol agents against the pest while also uncovering opportunistic bacterial pathogens that can directly damage potato tubers.
This study identifies a synonymous mutation in the P1 protein of Potato Virus Y (PVY) that attenuates viral pathogenicity by reducing RNA silencing suppression activity. The researchers developed a non-necrotic PVY-based vector from this mutant to achieve high-yield production of recombinant human interferons in Nicotiana species.
This study investigates the effects of polyploidization and drought priming on stress tolerance in the wild potato species Solanum kurtzianum. The researchers found that while diploid plants showed improved drought tolerance and tuber weight after priming, synthetic autotetraploids exhibited weaker priming responses, suggesting genome duplication impairs drought memory. These findings have important implications for utilizing wild relatives in breeding drought-resilient potato cultivars.
This study evaluates the reproducibility, verifiability, and methodological rigor of research investigating the relationship between potato consumption and colorectal cancer risk. By analyzing 18 studies, the authors highlight significant limitations in data sharing, reporting quality, and risk of bias, emphasizing the need for greater transparency in potato-related nutritional research.
This study investigates the genetic and molecular mechanisms of potato (Solanum tuberosum) tuber skin texture by mapping a major QTL to chromosome 4. Through transcriptome and co-expression analyses, the researchers identified StPXG4, a gene encoding a peroxygenase, along with its potential upstream regulators StMYB103 and StMYB58, as key candidates influencing skin texture and suberin/lignin accumulation. These findings provide valuable genetic targets for molecular breeding to improve potato tuber appearance and stress tolerance.
This study demonstrates that the viral genome-linked protein (VPg) of Potato virus Y (PVY) targets the host transcription factor MYB330 to suppress hydrogen-peroxide-mediated antiviral immunity. By interfering with MYB330's transcriptional repression of Catalase1, the virus promotes H2O2 scavenging and facilitates its own accumulation.
This study investigates how combining genetic selection of diploid potatoes with thermal processing reduces anti-nutritional factors (like solanine) to safe levels while retaining high amounts of beneficial nutrients. Using a zebrafish model, the authors demonstrate that this integrated approach mitigates gut inflammation and growth depression, promoting better growth performance and digestive capacity compared to conventional tetraploid potatoes.
This review explores the interaction between potato (Solanum tuberosum) root exudates and the soil-borne pathogen Verticillium dahliae, the causal agent of Verticillium wilt. It proposes a "germinate-to-exterminate" (G2E) strategy that uses root exudate metabolites to stimulate premature germination of fungal microsclerotia for sustainable disease control.
This study identifies two AP2/ERF transcription factors, StRAP2.7a and StRAP2.7b, that promote stolon and tuber formation in potato (Solanum tuberosum). The researchers demonstrate that these transcription factors regulate trans-zeatin biosynthesis and directly activate the key tuberization-regulatory gene StSP6A. These findings elucidate the molecular mechanisms of potato tuberization and offer potential genetic targets for breeding high-yielding cultivars.
The study introduces a portable diagnostic platform combining RPA-CRISPR/Cas12a and a microneedle patch for the rapid, early-stage detection of Phytophthora infestans in potatoes. The system enables efficient leaf sampling and smartphone-based fluorescence analysis, detecting the pathogen before visible symptoms appear. This technology provides a field-deployable tool for early diagnosis and surveillance of potato late blight.
