Source-sink regulation by sugar and stress
TLDR
Accumulating evidence for crosstalk, modulation and integration between signalling pathways responding to phytohormones, phosphate, light, sugars, and biotic and abiotic stress-related stimuli seem to play a central role in source-sink regulation.About:

Plant cellular and molecular responses to high salinity.
TL;DR: Evidence for plant stress signaling systems is summarized, some of which have components analogous to those that regulate osmotic stress responses of yeast, some that presumably function in intercellular coordination or regulation of effector genes in a cell-/tissue-specific context required for tolerance of plants.

Sugar Sensing and Signaling in Plants: Conserved and Novel Mechanisms
TL;DR: In this article, the experimental amenability of yeast as a unicellular model system has enabled the discovery of multiple sugar sensors and signaling pathways, and a central role for hexokinase (HXK) as conserved glucose sensor.

How Plants Cope with Water Stress in the Field? Photosynthesis and Growth
Maria Manuela Chaves,João Pereira,João Maroco,Maria Luísa Rodrigues,Cândido Pinto Ricardo,Maria Leonor Osório,Isabel S. Carvalho,T. Faria,Carla Pinheiro +8 more
TL;DR: Differences among species that can be traced to different capacities for water acquisition, rather than to differences in metabolism at a given water status, are described.
Journal ArticleDOI
Sugar Sensing and Signaling in Plants
TL;DR: In addition to their essential roles as substrates in carbon and energy metabolism and in polymer biosynthesis, sugars have important hormone-like functions as primary messengers in signal transduction.

TL;DR: This investigation provides new insight into the mechanisms of plant adaptation to thermal stress at the metabolite level, reveals relationships between heat- and cold-shock responses, and highlights the roles of known signaling molecules and protectants.

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.

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.

TL;DR: It is proposed that HK 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.

Glucose and ethylene signal transduction crosstalk revealed by an arabidopsis glucose-insensitive mutant
TL;DR: The isolation and characterization of gin1 reveal an unexpected convergence between the glucose and the ethylene signal transduction pathways, and GIN1 may function to balance the control of plant development in response to metabolic and hormonal stimuli that act antagonistically.
