Reconciling canopy light interception and photosynthetic efficiency to optimize source-sink coordination and yield formation in winter wheat [PDF]

BMC Plant Biology
Background Optimizing the seeding rate is critical for wheat productivity. However, excessive densification often compromises individual photosynthetic efficiency to maximize canopy light interception, creating a trade-off that constrains yield.

Role of Triose Phosphate Utilization in photosynthetic response of rice to variable carbon dioxide levels and plant source-sink relations [PDF]

bioRxiv, 2019
This study aimed to understand the physiological bases of rice photosynthesis response to C source-sink imbalances, with focus on dynamics of the photosynthetic parameter TPU (Triose Phosphate Utilization).

Recent advances in the long-distance transport of sugars by the phloem and consequences on source-sink relations

, 2023
International audienceThe distribution of photoassimilates in the plant relies on the phloem functions from source to sink organs. Phloem sugar transport is regulated by SUC/SUT and SWEET sugar transporters. We observed that deregulation of SUT1 or SUT2

Impact of various soil hydraulic properties and water source-sink relations on plant rings formation and sizes under arid conditions

, 2020
In semi-arid and arid environments, clonal plants occasionally appear in ring patterns with a barren soil centre. There is a general agreement that this pattern forms when ramets grow radially, leaving a dead centre where the parent plant once was ...

The Role of Source-Sink Relations between Photosynthetic and Assimilate-Consuming Organs in Regulation of Plant Photosynthesis [PDF]

, 2017
Cause and effect relationships between chloroplast photochemical reactions, CO2 assimilation and oxygen photosynthetic metabolism, transport of sugars in the phloem, apoplastic invertase and leaf stomata activity have been established.

Investigating phloem transport dynamics in Arabidopsis through compartmental modelling of positron emission tomography data [PDF]

Plant Methods
Background Phloem is the long-distance transport tissue of vascular plants in which photoassimilates are distributed from sources (e.g., leaves) to sinks (e.g., roots, fruits).

Hormonal regulation of source-sink relations to maintain crop productivity under salinity : a case study of root-to-shoot signalling in tomato

, 2010
Salinity decreases crop yield first by reducing growth of assimilate-consuming sink organs and, second, by decreasing assimilate production in photosynthetically active source tissues.

Triose phosphate utilization in leaves is modulated by whole-plant sink–source ratios and nitrogen budgets in rice [PDF]

, 2023
International audienceTriose phosphate utilization (TPU) is a biochemical process indicating carbon sink-source (im)balance within leaves. When TPU limits leaf photosynthesis, photorespiration-associated amino acid exports probably provide an additional ...
