Sugar-Will-Eventually-be-Exported Transporters (SWEETs) play a crucial role in sugar transport plants, mediating both plant development and stress responses. Despite their importance, there has been limited research characterizing the functional characteristics of CnSWEET genes coconut (Cocos nucifera). In this study, we conducted systematic analysis SWEET using bioinformatics, subcellular localization studies, silico promoter analysis, assays with yeast mutants. A total 16 were identified grouped into four clades. Clade I contained highest number (eight), derived from pairs duplicated genomic segments. contrast, other clades had fewer (one to four) compared those Arabidopsis species Arecaceae family. An extensive gene expansion MSCanX indicated significant divergence patterns, between within monocots dicots, as well among closely related same Notable variations conserved protein motifs transmembrane helices (TMHs) detected clades, affecting proteins. Specifically, seven TMHs associated proteins located cell membrane, while CnSWEET2A, which five TMHs, was found membrane cytosol. Promoter revealed that some endosperm or seed specific expression, consistent expression patterns observed transcriptome data. Functional genes, transcript sequences supported by data, mutant complementation assays. This demonstrated diverse activities for sucrose, fructose, glucose, galactose, mannose. Our findings provide valuable insights diversity coconuts potential roles responses development.

Beyond Energy: How Small‐Molecule Sugars Fuel Seed Life and Shape Next‐Generation Crop Technologies

Journal of Agronomy and Crop Science, Journal Year: 2025, Volume and Issue: 211(2)

Published: March 1, 2025

ABSTRACT Small‐molecule sugars, such as glucose, sucrose, trehalose and raffinose, are essential for seed germination, seedling establishment stress resilience. These sugars act both energy sources signalling molecules, regulating osmotic balance, gene expression critical metabolic pathways involved in early growth. Key enzymes, including α‐amylase ( AMY1 AMY2 ), hexokinase HXK1 ) sucrose‐phosphate synthase (SPS), facilitate carbohydrate mobilisation during fueling glycolysis, the tricarboxylic acid (TCA) cycle pentose phosphate pathway (PPP). Hormonal interactions, particularly with gibberellins (GA) abscisic (ABA), integrate sugar metabolism developmental environmental cues. Sugar transport proteins, Sugars Will Eventually be Exported Transporters (SWEET), Sucrose (SUT) Tonoplast (TST), ensure efficient distribution to growing tissues, whereas SNF1‐related kinase 1 (SnRK1) modulates growth responses, maintaining cellular homeostasis. Innovative treatments, priming, biopriming encapsulation, have proven effective improving germination rates, tolerance vigour by optimising regulation, activation microbial interactions. Sugar‐based treatments offer substantial potential enhancing crop productivity Future research should focus on refining these strategies, exploring sugar–hormone interactions using genomic tools advance improvement. Thus, small‐molecule hold transformative sustainable agriculture, providing a route enhance technology adaptability global challenges.

Gene expression and soluble sugar accumulation in perennial fruits

CABI Reviews, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 18, 2024

Abstract Soluble sugars primarily contribute to fruit flavouring and are crucial for quality. Carbohydrate accumulation in fruits is a multifaceted process that can be influenced by their biosynthesis capacity, sink strength, homeostasis, vacuolar storage ability. Moreover, total soluble sugar contents also vary among different varieties/species environmental conditions. Numerous studies have elucidated the carbohydrate regulatory mechanism fruits; however, there knowledge gap regarding most important contributor perennial fruits. Here, we briefly discussed recent advances, including long-distance transportation, metabolism storage, transcript factors Most importantly, strength factor trap more maintaining continuous unloading genes of cell wall invertase; moreover, sucrose transporters/pyrophosphatase play key roles This review delivers comprehensive summary findings regulation quality improvement, which may facilitate optimisation crops enhanced
