Transitory starch is formed in chloroplasts during the day and broken down at night. We investigated carbon export from chloroplasts resulting from transitory-starch breakdown. Starch-filled chloroplasts from spinach (Spinacia oleracea L. cv. Nordic IV) were isolated 1 h after the beginning of the dark period and incubated for 2.5 h, followed by centrifugation through silicone oil. Exported products were measured in the incubation medium to avoid measuring compounds retained inside the… Expand
The role of amylomaltase in maltose metabolism in the cytosol of photosynthetic cells
TLDR
Results show that Arabidopsis has an amylomaltase that is involved in the conversion of maltose to sucrose in the cytosol, and it is proposed that maltose metabolism in the cytoplasm of Arabidoptera leaves is similar to that in the Cytosol of E. coli. Expand
Blocking the Metabolism of Starch Breakdown Products in Arabidopsis Leaves Triggers Chloroplast Degradation
TLDR
It is proposed that the accumulation of maltose and malto-oligosaccharides causes chloroplast dysfunction, which may by signaled via a form of retrograde signaling and trigger chloropleft degradation. Expand
The importance of maltose in transitory starch breakdown.
TLDR
It is hypothesized that maltose metabolism is a bridge between transitory starch breakdown and the plants' adaptation to changes in environmental conditions, and could provide a mechanism for adjusting starch breakdown rates to day length. Expand
Carbon Balance and Circadian Regulation of Hydrolytic and Phosphorolytic Breakdown of Transitory Starch1
TLDR
Maltose was increased under photorespiratory conditions in both wild type and plants lacking starch phosphorylase, indicating that regulation of starch breakdown may occur at a point preceding the division of the hydrolytic and phosphorolytic pathways. Expand
β-Maltose Is the Metabolically Active Anomer of Maltose during Transitory Starch Degradation1[w]
TLDR
It is concluded that β-maltose is the metabolically active anomer of maltose and that a sufficient gradient of β-Maltose exists between the chloroplast and cytosol to allow for passive transport of Maltose out of chloroplasts at night. Expand
The diurnal metabolism of leaf starch.
TLDR
The present review provides an overview of starch biosynthesis, starch structure and starch degradation in the leaves of plants, focusing on recent advances in each area and highlighting outstanding questions. Expand
A transglucosidase necessary for starch degradation and maltose metabolism in leaves at night acts on cytosolic heteroglycans (SHG).
TLDR
Evidence is presented that DPE2 acts on the recently identified cytosolic water-soluble heteroglycans (SHG) as does the cytOSolic phosphorylase (EC 2.4.1.1) isoform, and in vitro two-step (14)C labeling assays are demonstrated that the two transferases can utilize the same acceptor sites of the SHG. Expand
Daylength and Circadian Effects on Starch Degradation and Maltose Metabolism1
TLDR
The expression of genes encoding starch degradation-related enzymes was under very strong circadian control in continuous light, and the amount of maltose showed a strong endogenous rhythm close to 24 h, indicating that maltose metabolism is under circadian control. Expand
Feedback Inhibition of Starch Degradation in Arabidopsis Leaves Mediated by Trehalose 6-Phosphate1[W][OPEN]
TLDR
It is proposed that Tre6P is a component in a signaling pathway that mediates the feedback regulation of starch breakdown by sucrose, potentially linking starch turnover to demand for sucrose by growing sink organs at night. Expand
Cellular and organ level localization of maltose in maltose-excess Arabidopsis mutants
TLDR
It is concluded that maltose accumulated in the cytosol of leaves can be carried from the shoots to the roots and that maltosing in the chloroplast of mex1-1 leaves is not mobilized. Expand

The role of amylomaltase in maltose metabolism in the cytosol of photosynthetic cells
TLDR

Export of carbon from chloroplasts at night
TLDR
It is concluded that most carbon leaves chloroplasts at night as Glc, maltose, or higher maltodextrins under normal conditions. Expand
Maltose metabolism by pea chloroplasts
TLDR
It is suggested that maltose phosphorylase, using glucose-1-phosphate formed from starch by α-glucan phosphoryLase, is responsible for, at least some of, the synthesis of maltose during starch breakdown by pea chloroplasts in vitro. Expand
Metabolite export of isolated guard cell chloroplasts of Vicia faba.
TLDR
The release of carbon from guard cell chloroplasts as a source for the production of organic osmotica was investigated and the presence of phosphate in the medium was essential for the release of phosphorylated compounds and also strongly enhanced the export of glucose and maltose. Expand
Characterization of starch breakdown in the intact spinach chloroplast.
TLDR
It was concluded that chloroplastic starch was degraded principally by the Embden-Meyerhof pathway and by a pathway involving amylolytic cleavage and the oxidative pentose phosphate pathway is the probable source of ribose 5-phosphate. Expand
Carbohydrate breakdown by chloroplasts of Pisum sativum.
TLDR
Starch breakdown in pea chloroplasts is held to be dominantly phosphorolytic with the products being metabolized via the oxidative pentose phosphate pathway and glycolysis to 3-phosphoglycerate, triose phosphates and CO2 that are exported to the cytoplasm. Expand
Physiological rates of starch breakdown in isolated intact spinach chloroplasts.
TLDR
Starch breakdown with rates above 10 muatom carbon per mg chlorophyll per hour has been monitored in spinach chloroplasts and compares favorably with the rates in whole leaves and showed that starch phosphorolysis was the major pathway leading to phosphorylated endproducts. Expand
Pathway of starch breakdown in photosynthetic tissues of Pisum sativum.
TLDR
Investigation of the pathway of starch breakdown in the photosynthetic tissues of Pisum sativum showed that starch was rapidly metabolized in the dark at rates of 0.04--0.06 mumol glucose/min per g fresh weight, and it was proposed that starch Breakdown in pea chloroplasts is phosphorolytic. Expand
Carbon Partitioning in a Flaveria linearis Mutant with Reduced Cytosolic Fructose Bisphosphatase.
TLDR
The results indicate that this mutant survives the reduced cytosolic fructose-1,6-bisphosphatase activity by partitioning more carbon to starch and less to sucrose during the day and remobilizing the excess starch at night. Expand
Metabolite levels during induction in the chloroplast and extrachloroplast compartments of spinach protoplasts.
TLDR
It is concluded that the causes of the induction lag in protoplasts can differ from those in isolated chloroplasts, and it is suggested that fructose-1,6-bisphosphatase and ribulose- 1,5-bisPhosphate carboxylase may limit flux in the Calvin cycle during induction. Expand
