Extensive post-translational processing of potato tuber storage proteins and vacuolar targeting

Vacuolar targeting and posttranslational processing of the precursor to the sweet potato tuberous root storage protein in heterologous plant cells.

Sporamin, the tuberous root storage protein of the sweet potato, which is localized in vacuoles, is synthesized as a prepro-precursor with an N-terminal sequence of amino acids that includes a signal peptide and an additional pro-segment of 16 amino acids. A full-length cDNA for sporamin was placed downstream of the 35 S promoter of cauliflower mosaic virus and introduced into tobacco and sunfl...

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,...

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...

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....
