Engineering Source-Sink Relations by Prime Editing Confers Heat-Stress Resilience in Tomato and Rice

Cell
A 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 ...

Sex-specific physiology and source-sink relations in the dioecious plant Silene latifolia

Oecologia, 1996
Differences 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 ...

The Role of the Transport System in the Control of the Source–Sink Relations in Pinus sylvestris

Russian Journal of Plant Physiology, 2003
Morphophysiological correlations were studied in medium-aged (20- to 60-year-old) Scots pine trees under the northern taiga conditions. Under various ecological conditions, pine trees developed a well-balanced structure, with close linear relationships between needle and root weight and their cross-section areas in all components of the continuous ...

Effects of Light Spectral Quality on Morphogenesis and Source–Sink Relations in Radish Plants

Russian Journal of Plant Physiology, 2001
The accumulation of dry matter and the content of major phytohormones in the aboveground and underground plant parts, as well as light curves and the diurnal course of photosynthesis in the leaves were studied in radish (Raphanus sativusL.) plants of different ages that were grown under red (RL) or blue (BL) light.

Alteration of cotton source–sink relations with plant population density and mepiquat chloride

Field Crops Research, 2010
Abstract 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.

Source-sink relations of sunflower plants as affected by a parasite modifies carbon allocations and leaf traits

Plant Science, 2018
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.

The Effect of Light Regime on Source–Sink Relations in the Shade-Enduring Ajuga reptans Plant

Russian Journal of Plant Physiology, 2004
A quantitative approach to the evaluation of source–sink relations in Ajuga reptans plants grown under the forest canopy (shade plants) and on an open plot (sun plants) was worked out in terms of growth characteristics, CO2 exchange, and carbon balance.

Effects of biologically active compounds on source-sink relations in plants during reproductive period

Doklady Biological Sciences, 2008
Due to source‐sink relations, a redistribution of plastic compounds occurs between plant organs during their ontogeny. The inflorescence (ear, panicle) is a main sink in annual grasses during their reproductive period. Although source‐sink relations are genetically determined, such factors as weather conditions, mineral nutrition, and biologically ...

Root Development and Source-Sink Relations in Carrot,Daucus carotaL

Journal of Experimental Botany, 1980
Physiological responses to root pruning were investigated by comparing 14C02 fixation rates, the partitioning of ""?-labelled assimilate, and soluble and insoluble carbohydrate levels in the leaves of carrot plants following the removal of some of the fibrous roots, or fibrous roots and part of the tap root. Root pruning reduced 14C02 fixation by 28-45%

Source–Sink Relations in the Organs and Tissues of Silver Birch during Different Scenarios of Xylogenesis

Russian Journal of Plant Physiology, 2019
Source–sink relations in the “leaf–stem–root” system at the time of cambial growth were studied in two forms of silver birch: common birch (Betula pendula Roth var. pendula) and Karelian birch (B.pendula var. carelica (Merckl.) Hamet-Ahti). As compared with common birch, reduced sucrose content in the leaves of elongated (auxiblasts) and short ...
