Carbohydrate sinks have been described by their ability to attract photosynthate, denoted by sink strength, and by their priority rank ordering for supply in the presence of a reduced availability of photosynthate. Sink strength has been de...
Sink strength as a determinant of dry matter partitioning in the whole plant [0.03%]
sink strength决定整个植物干物质分配的重要性

Dry matter partitioning is the end result of the flow of assimilates from source organs via a transport path to the sink organs. The dry matter partitioning among the sinks of a plant is primarily regulated by the sinks themselves. The effe...

It is argued that it is not possible to predict the flux of assimilate into a sink by making a measurement on that sink alone. Rather carbon flux is a whole-plant property and can only be predicted from measurements made simultaneously in s...

Great strides have been made in the last 15 years in our understanding of phloem mobility of xenobiotics. The subject has been transformed from a poorly understood phenomenon to a process that can be accurately described by the physicochemi...
Effect of mineral nutritional status on shoot-root partitioning of photoassimilates and cycling of mineral nutrients [0.03%]
矿营养状态对光合产物分配及养分循环的影响

Mineral nutrients taken up by the roots are, as a rule, transported in the xylem to the shoot, and photoassimilates transported in the phloem to the roots. According to the Thornley model of photosynthate partitioning, nutrient deficiencies...

Differential flows of photoassimilate result in patterns of dry matter distribution among plant organs. The extent to which these patterns are dependent on the flux of different mineral nutrients entering the root and the extent to which th...
The mechanism of assimilate partitioning and carbohydrate compartmentation in fruit in relation to the quality and yield of tomato [0.03%]

The limitation of tomato yield was investigated in a number of cultivars with contrasting fruiting habits. Unless light is limiting, yield is mainly restricted by the number or the size of the fruit (i.e. the sink strength) rather than the ...
Effect of environmental factors on whole plant assimilate partitioning and associated gene expression [0.03%]

Partitioning of assimilated carbon among sink organs is a critical factor that controls the rate and pattern of plant growth. Time-course measurements of plant and organ growth rates are useful for determining how regulation of carbon parti...

Uptake of the dipeptide [(3)H]Leu-Leu into leaf discs from mature broad bean (Vicia faba L.) was characterized. Uptake was maximal at pH 6.0 and appeared to be mediated by three systems with apparent K(m) values of 20 µM, 350 µM and 43 mM...
