• Sugar sensing and signaling in plants: conserved and novel mechanisms. (2006, background): “Cytokinins, on the other hand, can delay plant senescence, and studies with gin2 show that sugars and cytokinins work antagonistically (89).”
• Regulatory roles of sugars in plant growth and development (2018, background): “The gin2 mutant (with reduced glucose sensitivity), in turn, did not accumulate hexoses and the senescence was delayed, indicating a relationship of senescence with sugar sensitivity [63].”

• Sugars in crop plants (2011, background): “There is also evidence that hexokinase signalling interacts with auxin signalling to promote or inhibit growth (Moore et al., 2003).”
• Sugars induce anthocyanin accumulation and flavanone 3-hydroxylase expression in grape berries (2009, background): “The factors include the type of varieties, light ( Moore et al. 2003 ), temperature (Mori et al. 2005), plant hormone (Ban et al. 2003; Loreti et al. 2008), sugars (Vitrac et al. 2000) etc.”
• Exogenously-supplied trehalose protects thylakoid membranes of winter wheat from heat-induced damage (2010, background): “Furthermore, a role for sugars as signalling molecules has been widely documented (Moore et al. 2003, Rolland et al. 2006).”
• Sugar-based growth, astaxanthin accumulation and carotenogenic transcription of heterotrophic Chlorella zofingiensis (Chlorophyta) (2008, background): “29 expression of genes are suggested to result from the glucosesensing and signaling with the hexokinase as the key sensor in a variety of yeasts, mammals and higher plants [24–27], or from changes in the cytosolic redox state or electron flow of respiratory electron transport [24,28,29].”
• The Complex Regulation of Senescence (2012, background): “Overexpression of an Arabidopsis hexokinase gene (AtHXK1) in tomato led to a premature-senescence phenotype (Dai et al., 1999), while senescence was delayed in an Arabidopsis hexokinase (gin2) mutant (Moore et al., 2003).”

• Sucrose-Specific Induction of Anthocyanin Biosynthesis in Arabidopsis Requires the MYB75/PAP1 Gene1 (2005, background): “The AtHXK1 has separable catalytic and signaling functions and it was shown that downstream Glc metabolism is not required for hexokinase signaling (Moore et al., 2003).”
• Sucrose metabolism: regulatory mechanisms and pivotal roles in sugar sensing and plant development. (2004, background): “Once inside the importing cells, sucrose metabolism again becomes important to sugar sensing, this time to endogenous hexose- and possibly sucrose-signaling systems [4,5,10,11,22 ,28].”
• Developmental and hormonal control of leaf senescence (2007, background): “Both cytokinin and auxin are part of a regulatory complex for nutritional status of the plant through HXK1 signaling pathway (Moore et al., 2003).”
