“…This relationship could be due to competition for sucrose unloading between the storage organs (minitubers) and the above ground biomass (leaves and stems). Such competition for assimilates favours leaves which largely use the sucrose for respiration (Rykaczewska, 2004;Jackson, 1999). Similarly, the number of stolons per stem declines with increasing stem branching.…”

“…Several papers have described the above processes both in terms of signaling pathways involved in tuberization and of the metabolic changes occurring during storage organ development, maturation and storage [1][2][3][4][5][6]. Despite extensive research, especially into the early stages of development, the molecular changes that occur throughout the tuber life cycle are not yet fully resolved.…”

Proteomic analysis of the potato tuber life cycle

The tuber of potato (Solanum tuberosum) is commonly used as a model for underground storage organs. In this study, changes in the proteome were followed from tuberization, through tuber development and storage into the sprouting phase. Data interrogation using principal component analysis was able to clearly discriminate between the various stages of the tuber life cycle. Moreover, five well-defined protein expression patterns were found by hierarchical clustering. Altogether 150 proteins showing highly significant differences in abundance between specific stages in the life cycle were highlighted; 59 of these were identified. In addition, 50 proteins with smaller changes in abundance were identified, including several novel proteins. Most noticeably, the development process was characterized by the accumulation of the major storage protein patatin isoforms and enzymes involved in disease and defense reactions. Furthermore, enzymes involved in carbohydrate and energy metabolism and protein processing were associated with development but decreased during tuber maturation. These results represent the first comprehensive picture of many proteins involved in the tuber development and physiology.

“…This process requires the cessation of diageotropical growth and a change from transverse to longitudinal cell division in pith and cortex (Xu et al 1998). The bulk of tuber tissue is subsequently formed by cell expansion, randomly oriented cell division (Jackson 1999) and massive deposition of C-and N-assimilates such as starch and storage proteins (Visser et al 1994;Appeldoorn et al 1999), making the tuber a strong storage sink (Fernie and Willmitzer 2001). Tuber development is regulated by an interplay between endogenous and environmental signals and is orchestrated by coordinated transcriptional and metabolic changes (Kloosterman et al 2005(Kloosterman et al , 2008Ferreira et al 2010).…”
