Genome-wide identification of SCL gene family in potato (Solanum tuberosum L.) and expression analyses under phytohormones, drought and salt stress.

BMC plant biology | 2026-Aug-07

This study performs a genome-wide identification and characterization of the SCL gene family in potato, identifying 71 StSCL genes. It highlights the functional role of StSCL3 as a key transcriptional regulator in coordinating phytohormone signaling and abiotic stress responses, providing insights for future crop improvement.

Screening and synergistic evaluation of microbial strains for optimal bioconversion of potato waste via solid-state fermentation.

Journal of the science of food and agriculture | 2026-Nov-03

This study explores the valorization of potato peel waste (PPW) through solid-state fermentation using microbial consortia to improve nutritional value. By optimizing co-culture combinations, the researchers successfully increased the crude protein content and reduced fiber fractions, providing a framework for processing potato processing byproducts into valuable animal feed.

Peer review of the pesticide risk assessment of the active substance Bacillus velezensis strain FZB42.

EFSA journal. European Food Safety Authority | 2026-Nov

This paper outlines the regulatory risk assessment for the biological fungicide Bacillus velezensis strain FZB42, which is intended for use in protecting potatoes against Rhizoctonia species. It provides critical safety and efficacy data relevant to potato pathology and integrated pest management strategies.

Sublethal insecticide exposure and inbreeding impose a developmental bottleneck but enhance crop-damaging traits in surviving Colorado potato beetles.

Royal Society open science | 2026-Nov-04

This study examines how sublethal insecticide exposure and inbreeding affect the development and crop-damaging potential of the Colorado potato beetle (Leptinotarsa decemlineata). It demonstrates that while these stressors create a developmental bottleneck, surviving beetles exhibit compensatory plasticity that can increase their herbivory on potato crops.

The potato (Solanum tuberosum L.) transcription factor StPHR1 responds to low phosphate stress and regulates phosphorus accumulation.

Frontiers in plant science | 2026

This study characterizes the StPHR1 transcription factor in Solanum tuberosum, identifying it as a key regulator of phosphorus accumulation and low-phosphate stress tolerance. By utilizing CRISPR/Cas9 and proteomic profiling, the researchers demonstrate that manipulating StPHR1 can improve tuber yield and phosphorus-use efficiency, providing a genetic framework for breeding more resilient potato varieties.
