Changes of cellular structure of potato tuber parenchyma tissues during storage

Carotenogenesis during tuber development and storage in potato.

Germplasm of Solanum tuberosum and Solanum phureja exhibit a wide (over 20-fold) variation in tuber carotenoid content. The levels of carotenoids during tuber development and storage were compared in a high carotenoid-accumulating S. phureja accession (DB375\1) with two S. tuberosum cultivars (Pentland Javelin and Desiree) that accumulate lower levels of tuber carotenoid. On a dry weight basis,...

Assuring Potato Tuber Quality during Storage: A Future Perspective

Potatoes represent an important staple food crop across the planet. Yet, to maintain tuber quality and extend availability, there is a necessity to store tubers for long periods often using industrial-scale facilities. In this context, preserving potato quality is pivotal for the seed, fresh and processing sectors. The industry has always innovated and invested in improved post-harvest storage....

-generating activity in potato tuber tissues

Rapid generation of reactive oxygen species (ROS) at the cell surface has been implicated in plant defence responses. Genetic evidence indicates that a plant NADPH oxidase (Rboh; respiratory burst oxidase homologue) is associated with oxidative burst. However, there is not enough physiological evidence of Rboh localization available yet. Isozyme-specific antibodies against potato StrbohA and St...

Analysis of the Components Released from Potato Tuber Tissues during Maceration by Pectolytic Enzymes.

Endo-pectin lyase and endo-polygalacturonase of Aspergillus japonicus attack the middle lamella of plant tissue and cause tissue maceration. Galacturonides, neutral sugars, and proteins were released from potato tuber tissues during maceration by both purified enzymes. These three components accounted for 92% of the soluble products. The neutral sugars released were rhamnose, arabinose, and gal...
