Genetic Control of Photosynthate Metabolism

1990
The complexity of the control of metabolic processes involved in photosynthesis is becoming increasingly apparent. The plant is able to respond rapidly to changes environmental conditions and, superimposed on this, there are inherent developmental patterns which lead to long-term changes in enzyme levels.

Export of Photosynthates from the Leaf

2018
Mature leaves export approximately 80% of the carbon they fix by photosynthesis. Although most attention has been devoted to studying export of recently synthesized sugar, this is only one source of nutrients that enter the export stream. The mesophyll also supplies amino acids and other chemical species; ions and compounds are rerouted from the xylem,

Apple fruitlet thinning and photosynthate supply

The Journal of Horticultural Science and Biotechnology, 1998
SummaryThe effects of reduced photosynthate supply on apple fruit retention was investigated during the fruit setting period in two years with mature ‘Jonagold’/M.9 apple trees. Shading (90%, 7–12 d after petal fall, DAPF) caused fruitlet drop by 23 DAPF and strongly reduced the yield. Carbaryl did not enhance the abscission caused by shading.

Application of Microsoft Photosynth Within Heritage

2009
Photosynth technology has the potential to enhance how heritage is both accessed and experienced, from both a public and specialist perspective. The 3-D environment allows the user to immerse in a subject without the need for specialist software or equipment, whether it's a large site or the smallest artefact.

Short Term Interactions between Flows of Photosynthate

Journal of Experimental Botany, 1983
Using radioactive tracers, interactions between flows of photosynthetic assimilate were observed in vivo with several species. Changes in translocation from one source (brought about by repeated chilling and re-warming which stops and re-starts flow) can cause an immediate and partially compensating change in translocation from another source.

Translocation of Photosynthate in Bulbing Onions

Australian Journal of Plant Physiology, 1983
[14C]urea was injected into the leaf lumens of growing onion plants (Allium cepa L.) and the redistribution of photosynthate was investigated after 24 h. Injections were into either an older mature leaf or into a younger recently enlarged leaf. Most of the photosynthate was retained either in the green blade of the treated leaf or in ...

Photosynthate Limitation of Symbiotic N2 Fixation

1981
For the past several years our laboratory has studied various aspects of the energetics of nitrogen fixation, experiments leading to the conclusion that there is a high metabolic energy cost for this process (1). Several of these experiments will be discussed below (see Figs. 1 and 4 for integration of this work).

Photosynthate Partitioning in Sugarbeet¹

Crop Science, 1978
Partitioning of photosynthate to various parts of a crop has a marked influence on economic yield. We used the sugarbeet (Beta vulgaris L.) to investigate quantitatively the effect of this partitioning on growth. Plants were grown for 21 days in the growth chamber.

Translocation Kinetics of Photosynthates

1975
It is hard to imagine what working on translocation must have been like before radioactive tracers were available. So much of the information we have, particularly about physiological aspects, is based on tracer methodology that it would be difficult even to list it.

A Comparison of Photosynthate Allocation in Lakes

Journal of Great Lakes Research, 1996
Abstract We compared the relationships between photosynthate allocation to protein, carbohydrate, lipid and low molecular weight (LMW) fractions and the variables daylength and water temperature in Lakes Huron, Michigan, and Ontario as well as three smaller headwater lakes in the Lake Ontario drainage.
