The Study of Source-Sink Relations by Comparison of Weight and Grain in the Modern and Old Wheat Cultivars [PDF]

Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017
Seed filling in wheat is controlled by the availability of substrate (source strength), the capacity of the organs to utilize it for seed growth (sink strength).

Corn Grain Weight: Dependence upon Nitrogen Supply and Source-Sink Relations

Kansas Agricultural Experiment Station Research Reports, 2021
From a yield component perspective, final grain yield in corn (Zea mays L.) is the result of the number of grains per unit area and their final grain weight. The understanding of grain weight parameters, the rate and duration of grain growth, is critical to improve our rational design of management practices and breeding strategies.

Data Mining Nitrogen-Responsive Gene Expression for Source–Sink Relations and Indicators of N Status in Potato

Agronomy, 2020
Potato tuber yields depend on nitrogen (N) supply, which affects source–sink relations. Transcriptome sequencing of the foliar source using a single field trial identified gene expression responsive to 180 kg N ha−1.

Changes in Number and Weight of Wheat and Triticale Grains to Manipulation in Source-Sink Relationship [PDF]

International Journal of Agronomy, 2019
The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and yield components.

Centennial Change and Source–Sink Interaction Process of Traditional Agricultural Landscape: Case from Xin’an Traditional Cherry Cultivation System (1920–2020)

Land, 2022
In contrast to modern agriculture, long-standing traditional agricultural practices such as agricultural heritage systems (AHS) are important inspirations for promoting harmonious human–land relations.

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

Current 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 ...

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.

FLOWERING LOCUS T1 is a pleiotropic regulator of reproductive development, plant longevity, and source-sink relations in barley

Plant Physiology
Abstract Source–sink interactions play a critical but mechanistically underexplored role in coordinating reproductive output and longevity in plants. Here, we investigated the role of FT1 , the barley homolog of the florigen FLOWERING LOCUS T (

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).

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

, 2023
The 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 in Tomato lines had various consequences on plant growth, sugar phloem transport rate and phloem sap composition.
