TLDR
The molecular details of sugar sensing and sugar-mediated signal transduction pathways are unclear but recent results suggest that hexokinase functions as an important plant sugar sensor in a way that is similar to that found in yeast.About:

Understanding plant responses to drought — from genes to the whole plant
TL;DR: Attention is drawn to the perception and signalling processes (chemical and hydraulic) of water deficits, which are essential for a holistic understanding of plant resistance to stress, which is needed to improve crop management and breeding techniques.
Journal ArticleDOI
Seed Dormancy and Germination
TL;DR: In this article, the role of the plant hormones abscisic acid and gibberellin in the regulation of seed dormancy and germination has been investigated in Arabidopsis thaliana.
Journal ArticleDOI
Sink regulation of photosynthesis
TL;DR: This work has suggested that carbohydrate accumulation in leaves when there is an imbalance between source and sink at the whole plant level can lead to decreased expression of photosynthetic genes and accelerated leaf senescence, and in a high CO2 world this may become a more prevalent feature of photosynthesis regulation.

The interaction between elevated carbon dioxide and nitrogen nutrition: the physiological and molecular background
Mark Stitt,Annemarie Krapp +1 more
TL;DR: In this article, a review summarizes the numerous studies that have described the interaction between the nitrogen supply and the response of photosynthesis, metabolism, and growth to elevated [CO2].
Journal ArticleDOI
Sugar-induced signal transduction in plants
TL;DR: The role of sugar signaling in seed development and in seed germination is discussed, especially with respect to the various mechanisms by which sugar signaling controls gene expression.

Carbohydrate-modulated gene expression in plants.
TL;DR: The review addresses the above from molecular to whole-plant levels and considers emerging models for sensing and transducing carbohydrate signals to responsive genes.

Brassinosteroids Rescue the Deficiency of CYP90, a Cytochrome P450, Controlling Cell Elongation and De-etiolation in Arabidopsis
Miklós Szekeres,Kinga Németh,Zsuzsanna Koncz-Kalman,Jaideep Mathur,Annette Kauschmann,Thomas Altmann,George P. Rédei,Ferenc Nagy,Jeff Schell,Csaba Koncz,Csaba Koncz +10 more
TL;DR: Brassinosteroids compensate for different cell elongation defects of Arabidopsis det, cop, fus, and axr2 mutants, indicating that these steroids play an essential role in the regulation of plant development.
Journal ArticleDOI
Hexokinase as a sugar sensor in higher plants.
TL;DR: Evidence is presented that the first enzyme in the hexose assimilation pathway, hexokinase (HXK), acts as a sensor for plant sugar responses, suggesting that HXK is a dual-function enzyme with a distinct regulatory function not interchangeable between plants and yeast.

Sugar sensing in higher plants.
Jyan-Chyun Jang,Jen Sheen +1 more
TL;DR: It is proposed that hexokinase may have dual functions and may act as a key sensor and signal transmitter of sugar repression in higher plants and the involvement of glycolysis and other metabolic pathways is eliminated.
