Next-generation strategies for understanding and influencing source–sink relations in crop plants

open access: yesCurrent Opinion in Plant Biology, 2018
Whether plants are source or sink limited, that is, whether carbon assimilation or rather assimilate usage is ultimately responsible for crop yield, has been the subject of intense debate over several decades. Here we provide a short review of this debate before focusing on the use of transgenic intervention as a means to influence yield by modifying ...

Analyzing the significance of defoliation in growth, photosynthetic compensation and source-sink relations

open access: yesPhotosynthetica, 2012
Leaf canopy plays a determining role influencing source-sink relations as any change in source activity (photosynthesis) affects sink metabolism. Defoliation (removal of leaves) influences growth and photosynthetic capacity of plants, remobilizes carbon and nitrogen reserves and accelerates sink metabolism, leading to improved source-sink relations.

Metabolite Signals Regulate Gene Expression and Source/Sink Relations in Cereal Seedlings [PDF]

open access: yesPlant Physiology, 1994
Our knowledge of the genetic structures and regulatory mechanisms active during cereal seedling development has increased dramatically in recent years. For this reason, a more integrated view of the molecular aspects of seedling development and physiology is needed. This review presents the Carbon Metabolite Signal Hypothesis, which attempts to explain

Regulation of source/sink relations by cytokinins

Plant Growth Regulation, 2000
Many physiological effects of cytokinins are well established and are known to be involved in various aspects of the plant life cycle. In contrast, little is known about how these effects are evoked at the molecular level. Since cytokinins have been shown to play a major role in the regulation of various processes associated with active growth and thus

Yield and source/sink relations of spring wheat cultivars

Field Crops Research, 1989
Abstract Spikelets from one side of the ear were completely removed at flowering (treated ear) to demonstrate the different responses of old and new spring wheat cultivars to source/sink manipulation. The concepts of potential ear productivity (doubled yield of the treated ear) and potential protein content in the remaining half of the ear were ...

Investigating Source-Sink Relations in Cassava by Reciprocal Grafts

Experimental Agriculture, 1982
SUMMARYThe relation between source potentials and sink capacities of four cassava (Manihot esculentaCrantz) varieties with different characteristics was investigated by means of reciprocal grafts. There were marked differences in the sink capacities (average stock effects) and source potentials (average scion effects) of the varieties.
