Tuber Storage Proteins

evaluation of genetic variation of different potato varieties using electrophoretic tuber storage proteins

potato (solanum tuberosum l.) ranks the fourth most important food crops in the world. determination of genetic diversity using different markers have a key role in plant breeding programs. in this research, sds-page technique was used as a tool for assessing genetic diversity relationships among 23 potato cultivars (solanum tuberosum l.). potato tubers proteins were extracted using laemmli met...

Eliminating potato seed tuber storage for isfahan area

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....

Ocatin. A novel tuber storage protein from the andean tuber crop oca with antibacterial and antifungal activities.

The most abundant soluble tuber protein from the Andean crop oca (Oxalis tuberosa Mol.), named ocatin, has been purified and characterized. Ocatin accounts for 40% to 60% of the total soluble oca tuber proteins, has an apparent molecular mass of 18 kD and an isoelectric point of 4.8. This protein appears to be found only in tubers and is accumulated only within the cells of the pith and perider...
