This study investigates genomic instability in the autotetraploid potato cultivar C88, identifying meiotic abnormalities that lead to widespread aneuploidy in its progeny. The research highlights biased chromosomal instability, particularly in chromosome 11, and reveals non-random haplotype transmission, providing insights into polyploid genome evolution and breeding.
This study identifies Bacillus subtilis NJ01 as a potential biocontrol agent against Phytophthora infestans, the pathogen responsible for potato late blight. The research utilizes in silico docking and molecular dynamics simulations to identify specific bacterial metabolites that may inhibit the CRN8 effector protein, providing insights for sustainable disease management.
This commentary highlights findings on how pattern-triggered immunity (PTI) induces alternative splicing of the potato NLR gene Rpi-vnt1.1. This splicing event removes a repressive N-terminal prodomain, enabling resistosome assembly and establishing a functional link between surface-mediated PTI and intracellular effector-triggered immunity (ETI) in potato.
This paper reviews the biology, global distribution, and genetic diversity of Rhizoctonia solani, the fungal pathogen causing black scurf and stem canker in potatoes. It evaluates the transition from traditional diagnostic methods to advanced molecular, genomic, and AI-driven technologies for more precise disease surveillance and management.
This study utilizes hyperspectral imaging and elastic-net logistic regression to non-destructively assess cold-induced sweetening (CIS) in stored potatoes. The research provides a method for monitoring sugar accumulation and browning potential, which are critical factors for potato quality and processing safety.
This study establishes an optimized protocol for the isolation and regeneration of mesophyll protoplasts from the potato cultivar Kufri Jyoti. The method provides a robust foundation for transgene-free genome editing in potatoes by facilitating the introduction of ribonucleoprotein complexes into plant cells.
This paper discusses the commercial adoption, regulatory landscape, and practical viability of RNA interference (RNAi)-based biopesticides in crop protection. It highlights the commercial registration of dsRNA products targeting major agricultural pests, specifically the Colorado potato beetle, as a milestone transitioning this biotechnology into real-world pest management strategies.
This study identifies R8 gene analogs in potato that act as negative modulators of R8-mediated resistance against late blight (Phytophthora infestans). These analogs suppress immune responses by disrupting effector recognition and interfering with the helper NLR protein NRC2, revealing an endogenous regulatory mechanism that helps prolong the durability of disease resistance.
This study demonstrates a strategy to balance growth and immunity in potato (Solanum tuberosum) by utilizing a humidity-inducible promoter to drive a late blight resistance gene. The resulting transgenic potato lines achieved robust late blight resistance under high relative humidity while avoiding the growth suppression and tuber yield penalties typically associated with constitutive resistance gene overexpression.
This study evaluates the antioxidant and antimicrobial properties of potato peel powder, combined with pomegranate peel powder, as a natural preservative in refrigerated chicken meatballs. The findings show that incorporating potato peels enhances cooking yield, sensory acceptability, and oxidative stability during storage, demonstrating the potential of potato processing byproducts in food science applications.
