This study identifies PVYN-Wi isolates as a cause of external tuber necrosis and cracking in potato crops in the San Luis Valley, Colorado. Because PVYN-Wi belongs to the O-serotype, it evades standard N-serotype antibody detection used in seed potato certification programs. These findings highlight the need to update PVY diagnostic and management strategies to better protect seed potato quality.
This study describes an efficient semi-selective culture medium (ClaYPGA/ClaYDC) combined with a highly specific PCR primer pair for the isolation and identification of all *Clavibacter* species. Because *Clavibacter* includes major agricultural pathogens such as *Clavibacter sepedonicus* (the causal agent of potato bacterial ring rot), this method provides an improved diagnostic tool for potato pathology and plant quarantine monitoring.
This study investigates how temperature and geographic population differences affect the efficacy of RNAi-based insecticides against the Colorado potato beetle, a major potato pest. The findings suggest that cooler temperatures reduce the effectiveness of gene silencing and mortality rates, which has significant implications for the timing and regional application of pest management strategies in potato cultivation.
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.
