Engineering source-sink relations by prime editing confers heat-stress resilience in tomato and rice
CellA 2°C climate-warming scenario is expected to further exacerbate average crop losses by 3%-13%, yet few heat-tolerant staple-crop varieties are available toward meeting future food demands. Here, we develop high-efficiency prime-editing tools to precisely knockin a 10-bp heat-shock element (HSE) into promoters of cell-wall-invertase genes (CWINs) in ...

Alteration of cotton source–sink relations with plant population density and mepiquat chloride
Field Crops Research, 2010Abstract Improvements in carbohydrate source–sink relations are needed to improve efficiency of yield formation in cotton ( Gossypium hirsutum L.). Most source–sink research has focused on leaf–boll relationships, with little study of vegetative storage reserves.

Regulation of source/sink relations by cytokinins
Plant Growth Regulation, 2000Many 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

Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is established.

Effects of source‐sink relations on photosynthetic acclimation to elevated CO2
Plant, Cell & Environment, 1991Abstract. While photosynthesis of C3 plants is stimulated by an increase in the atmospheric CO2 concentration, photosynthetic capacity is often reduced after long‐term exposure to elevated CO2. This reduction appears to be brought about by end product inhibition, resulting from an imbalance in the supply and demand of carbohydrates.

Sex-specific physiology and source-sink relations in the dioecious plant Silene latifolia
Oecologia, 1996Differences in reproductive demands between the sexes of dioecious plants could cause divergence in physiology between the sexes. We found that the reproductive effort of female Silene latifolia plants increased to more than twice that of male plants or female plants that were prevented from setting fruit by lack of pollination after 4 weeks of ...

Yield and source/sink relations of spring wheat cultivars
Field Crops Research, 1989Abstract 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 ...

Sunflower broomrape (Orobanche cumana) is a root holoparasitic plant causing major damage to sunflower (Helianthus annuus L.). Parasite infection initiates source-sink relations between the parasite (sink) and the host (source), allocating carbohydrates, water and nutrients to the parasite.

Source–sink relations and effects of post-anthesis canopy defoliation in wheat at low latitudes
The Journal of Agricultural Science, 1990SUMMARYSource–sink balance was studied by imposing different canopy defoliation treatments on wheat crops grown in Los Banos (Philippines) in 1985/86 and 1986/87, Sonora (Mexico) in 1972/73 and 1974/75 and New Delhi (India) in 1987/88. The crops were grown in replicated trials with optimum cultural management. Six defoliation treatments were imposed at

Root Development and Source-Sink Relations in Carrot,Daucus carotaL.
Journal of Experimental Botany, 1978Growth analysis and 14C02 feeding experiments have shown that the developing storage organ became an increasingly important sink for assimilates, accumulating 40% of the dry matter produced by the carrot plant within 9 weeks of sowing. The relative importance of each leaf in fixing and exporting 14C was assessed at two stages of development ...
