“…It will be interesting to explore the diverse functional roles and regulation of the ERD6‐like members in plant growth development under stress conditions. Recently, Miao et al (2020) performed the molecular characterization and promoter analysis of the novel sugar transporter gene ScERD6 in sugarcane ( Saccharum officinarum ) and observed the stress‐induced expression of ScERD6 in the leaves, roots, and stems under PEG and low‐temperature stress conditions.…”

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.

“…Recognizing the complexity of sugar accumulation in sugarcane, considerable efforts were directed to genomic research, particularly transcriptomics, to unravel the genetic elements and possible genetic regulatory networks of sucrose accumulation in sugarcane (Huang et al 2016;Thirugnanasambandam et al 2017;Chen et al 2019). These studies provided more clarity on molecular processes and genes likely to be involved in sugar metabolism and related biological processes (Reinders et al 2006;Chen et al 2016;Huang et al 2017;Thirugnanasambandam et al 2019;Miao et al 2020). This expanded knowledge, while strengthening the rationale for experimental manipulation of growth and sugar content in sugarcane, also highlights the degree of regulatory complexity inherent in sugarcane stem sucrose accumulation process (Garcia Tavares et al 2018;Chen et al 2019).…”
