This study identifies StSAUR31 as a negative regulator of enzymatic browning in potatoes by modulating polyphenol oxidase (PPO) activity and substrate availability. The research demonstrates that StSAUR31 interacts with StuPPO1 in an auxin-dependent manner, reducing its accumulation in plastids and lowering tyrosine levels to suppress browning.
This paper reviews the diversity and functional integration of pattern recognition receptors (PRRs) and nucleotide-binding leucine-rich repeat (NLR) receptors in potato and its wild relatives. It explores how understanding these immune signaling networks can be leveraged through genetic engineering and strategic stacking to develop durable resistance against major pathogens like Phytophthora infestans.
This study develops a sensitive fluorescence detection method using carbon quantum dots to quantify dinotefuran pesticide residues. The method was successfully validated in several food matrices, including potato, providing a tool for food safety and quality analysis in potato-derived products.
This study presents a novel, highly sensitive dual-mode lateral-flow immunoassay (LFIA) for the rapid on-site detection of Potato virus S (PVS) in field samples. The platform utilizes a specialized core-shell probe to achieve significantly lower detection limits than conventional methods, providing a practical tool for managing potato viral pathology.
This study evaluates the impact of replacing chemical nitrogen fertilizer with organic alternatives on potato yields and rhizosphere microbial communities in Northwest China. The research identifies that a 60% substitution strategy optimizes soil properties and significantly increases potato yields while altering the diversity of bacterial and fungal populations in the rhizosphere.
This study identifies StHY5 as a key transcription factor that promotes potato tuberization by directly activating the expression of the tuberigen signal StSP6A under short-day conditions. Functional validation shows that StHY5 overexpression increases tuber yield, establishing it as a critical regulator in the photoperiodic signaling pathway of Solanum tuberosum.
The study identifies a regulatory mechanism in the potato resistance protein Rpi-vnt1.1 where surface immune signaling triggers alternative splicing to remove an inhibitory N-terminal prodomain. This process prevents autoimmunity while allowing the NLR receptor to be activated by the Phytophthora infestans effector AVRvnt1, facilitating resistosome assembly and immune response.
This study evaluates the physicochemical and sensory properties of starch-based gel confectionery using different starch sources, including potato starch. The research highlights that potato starch formulations produced the softest gels and exhibited delayed moisture release compared to corn and mung bean starches.
This study confirms polyandry in the potato cyst nematode Globodera pallida and investigates how this reproductive behavior changes during adaptation to resistant potato cultivars carrying the GpaV gene. The research demonstrates that multiple paternity is highly prevalent in G. pallida populations and remains stable even when facing masculinizing plant resistance, providing insights for nematode control strategies.
This study develops biodegradable active films using potato starch and potato peel extract to enhance the preservation of fresh-cut potatoes. The research demonstrates that these potato-derived films possess significant antioxidant and antimicrobial properties, effectively reducing browning and delaying spoilage during storage.
