Title

Evidence of the crucial role of sucrose synthase for sink strength using transgenic potato plants (Solanum tuberosum L.)

Rita Zrenner; Marcel Salanoubat; Lothar Willmitzer; et al. The Plant Journal 1995. doi:10.1046/j.1365-313x.1995.07010097.x

Other claims from this paper (12)

Observation Inhibition of Susy activity in the antisense plants was tuber-specific.
Intervention effect Susy inhibition caused no change in sucrose content in developing potato tubers.
Intervention effect Susy inhibition caused a strong accumulation of reducing sugars in developing potato tubers.
Intervention effect Susy inhibition inhibited starch accumulation in developing potato tubers.
Observation Invertase activities increased 40-fold in parallel with the increase in hexoses.
Observation Hexokinase activities showed no considerable changes.
Observation The reduction in starch accumulation was not due to inhibition of the major starch biosynthetic enzymes.
Observation Soluble tuber proteins were reduced.
Observation The reduced protein accumulation was mainly due to a decrease in patatin, the 22 kDa proteins and the proteinase inhibitors.
Observation The lowered storage protein accumulation was not a consequence of the availability of the free amino acid pool in potato tubers.
Intervention effect Susy antisense plants showed no increase in tuber number per plant.
Mechanism The authors conclude that sucrose synthase is the major determinant of potato tuber sink strength.

Potato Stolon and Tuber Growth Influenced by Nitrogen Form

Yuan Gao; Liguo Jia; Bo Hu; et al. Plant Production Science 2014. doi:10.1626/pps.17.138

Other claims from this paper (7)

Intervention effect Nitrate-fed potato plants made more stolons than ammonium-fed plants at tuber initiation.
Intervention effect Nitrate-fed plants made thicker stolons than ammonium-fed plants.
Intervention effect Nitrate-fed stolon tips swelled or formed tubers earlier than ammonium-fed tips.
Intervention effect Nitrate-fed plants produced more tubers than ammonium-fed plants.
Intervention effect Harvest tuber yield did not differ significantly between nitrogen forms.
Intervention effect Nitrate-fed plants had lower shoot growth rate at tuber initiation, offered as a possible explanation for unchanged yield.
Intervention effect Nitrate-fed shoots were sometimes heavier than ammonium-fed shoots during tuber bulking.

Title

Influence of osmotic stress on the respiration of potato tuber callus

Linus H. W. van der Plas; Marijke J. Wagner Physiologia Plantarum 1984. doi:10.1111/j.1399-3054.1984.tb04592.x

Other claims from this paper (14)

Intervention effect Potato callus fresh weight decreased upon transfer to mannitol medium
Intervention effect Potato callus dry weight increased upon transfer to mannitol medium
Intervention effect Osmolarity of the intracellular fluid of potato callus increased upon transfer to mannitol medium
Mechanism Mannitol is probably taken up from the medium until tissue osmolarity equals that of the medium
Intervention effect Respiration of potato callus increased upon transfer to medium with extra mannitol, especially per fresh weight
Intervention effect On a fresh weight basis, cytochrome and alternative pathway capacities did not change appreciably with extra mannitol
Intervention effect Participation of the alternative pathway in uninhibited respiration of potato callus rose from about 10% to 90% upon transfer
Association Increase in respiration is partly correlated with decrease in fresh weight upon transfer
Intervention effect Capacities of the cytochrome and alternative pathway declined per disc upon transfer
Intervention effect Total respiration per disc of potato callus significantly increased upon transfer
Mechanism Total respiration per disc increased due to increased participation of the alternative pathway
Intervention effect ATP production per disc was almost unchanged before and after transfer
Mechanism The alternative pathway may function as a reserve capacity in potato callus when cytochrome pathway ATP production is impaired
Intervention effect Growth of potato callus became negligible on medium with 0.5 M mannitol after osmotic adaptation
