“…Polyols (also called sugar alcohols) are water‐soluble sugars' derivatives categorized into cyclic (pinitol, myo‐inositol, and ononitol) and acyclic (sorbitol, mannitol, and inositol) compounds (Bhattacharya & Kundu, 2020). These molecules are accumulated in plants under salt, drought, and osmotic stress (Bhattacharya & Kundu, 2020). They serve several physiological functions including the translocation of carbon between source and sink organs, osmoprotection, antioxidant defense in biotic and abiotic stresses (Bhattacharya & Kundu, 2020; Noiraud et al, 2001b; Singh et al, 2015).…”

“…The WRKY transcription factor regulates the gene expression of GALACTINOL SYNTHASE and RAFFINOSE SYNTHASE , involved in the galactinol and raffinose oligosaccharides (RFO) biosynthesis. The RFO and galactinol help to alleviate the oxidative stress by inhibiting ROS (Bhattacharya & Kundu, 2020). The sugars and ABA signaling networks coordinately regulate the expression of ABI4 transcriptional regulator, which will further regulate the several sugar‐responsive genes family such as ALCOHOL DEHYDROGENASE (ADH) and α‐AMYLASE 3 (Rook et al, 2006).…”

It is believed that polyols have osmoprotective functions by forming a sphere of hydration around macromolecules and preventing metabolic inactivation under low osmotic potential (Schneider, 2015; Williamson et al, 2002).…”

The sessile nature of plants' life is endowed with a highly evolved defense system to adapt and survive under environmental extremes. To combat such stresses, plants have developed complex and well‐coordinated molecular and metabolic networks encompassing genes, metabolites, and acclimation responses. These modulate growth, photosynthesis, osmotic maintenance, and carbohydrate homeostasis. Under a given stress condition, sugars act as key players in stress perception, signaling, and are a regulatory hub for stress‐mediated gene expression ensuring responses of osmotic adjustment, scavenging of reactive oxygen species, and maintaining the cellular energy status through carbon partitioning. Several sugar transporters are known to regulate carbohydrate partitioning and key signal transduction steps involved in the perception of biotic and abiotic stresses. Sugar transporters such as SUGARS WILL EVENTUALLY BE EXPORTED TRANSPORTER (SWEETs), SUCROSE TRANSPORTERS (SUTs), and MONOSACCHARIDE TRANSPORTERS (MSTs) are involved in sugar loading and unloading as well as long‐distance transport (source to sink) besides orchestrating oxidative and osmotic stress tolerance. It is thus necessary to understand the structure–function relationship of these sugar transporters to fine‐tune the abiotic stress‐modulated responses. Advances in genomics have unraveled many sugars signaling components playing a key role in cross‐talk in abiotic stress pathways. An integrated omics approach may aid in the identification and characterization of sugar transporters that could become targets for developing stress tolerance plants to mitigate climate change effects and improve crop yield. In this review, we have presented an up‐to‐date analysis of the sugar homeostasis under abiotic stresses as well as describe the structure and functions of sugar transporters under abiotic stresses.

“…In addition to sucrose, they are also transported in the phloem of celery ( Apium graveolens L.), peach ( Prunus persica (L.) Batsch), or different plantain species ( Plantaginaceae ). Polyols are rich in stored reducing power and, like the above-mentioned compounds, potent ROS quenchers [ 24 ]. They are, therefore, not only attractive building blocks for plants providing both energy and carbon to sink organs but also compounds formed to mitigate abiotic and biotic stresses [ 25 , 26 ].…”

Potassium (K) is essential for the processes critical for plant performance, including photosynthesis, carbon assimilation, and response to stress. K also influences translocation of sugars in the phloem and regulates sucrose metabolism. Several plant species synthesize polyols and transport these sugar alcohols from source to sink tissues. Limited knowledge exists about the involvement of K in the above processes in polyol-translocating plants. We, therefore, studied K effects in Plantago major, a species that accumulates the polyol sorbitol to high concentrations. We grew P. major plants on soil substrate adjusted to low-, medium-, or high-potassium conditions. We found that biomass, seed yield, and leaf tissue K contents increased in a soil K-dependent manner. K gradually increased the photosynthetic efficiency and decreased the non-photochemical quenching. Concomitantly, sorbitol levels and sorbitol to sucrose ratio in leaves and phloem sap increased in a K-dependent manner. K supply also fostered plant cold acclimation. High soil K levels mitigated loss of water from leaves in the cold and supported cold-dependent sugar and sorbitol accumulation. We hypothesize that with increased K nutrition, P. major preferentially channels photosynthesis-derived electrons into sorbitol biosynthesis and that this increased sorbitol is supportive for sink development and as a protective solute, during abiotic stress.
