The availability of photosynthates is a critical determinant of shoot branching (or tillering in monocots). Carbohydrates, primarily in the form of sucrose, are synthesised in actively photosynthetic leaves (sources) and transported to non-photosynthetic tissues (sinks), such as tiller buds. Glucose, fructose, sucrose and their intermediates, including trehalose-6-phosphate (Tre6P), function both as energy sources and signalling molecules. Once sucrose is transported from source to sink tissues, it is rapidly hydrolysed into hexoses, which support starch accumulation, and the formation and elongation of tiller buds (outgrowth into a branch or tiller). This review aims to summarise recent discoveries with the focus on (i) sugar synthesis, metabolism, loading and unloading; (ii) sugars as crucial signals in regulating branching; (iii) roles of sugars in mediating the environment-modulated branching; (iv) the interactions between sugars and phytohormonal pathways that influence bud outgrowth and branching.

It has been reported that the nitrate transporters (NRTs) play critical roles for plants to survive in the nutrient-poor soils.

In the present study, we identified a NRT2.4-like protein (GsNRT2.4a) as an interactor of GsSnRK1.1 kinase. Our biophysical and physiological analyses indicate that GsNRT2.4a functions as an active NRT, and GsSnRK1.1 kinase phosphorylates the Ser518 residue at the carboxyl region of GsNRT2.4a. Under N starvation conditions, the double mutant nrt2.1/nrt2.2 (2nrtm) and the quadruple mutant nrt2.1/nrt2.2/kin10/kin11 (2kinm/2nrtm) exhibited compromised growth of Arabidopsis.

Furthermore, we determined that GsSnRK1.1 plays a pivotal role in modulating GsNRT2.4a activity in planta by phosphorylating GsNRT2.4a at the Ser518 site, thereby collaboratively modulating plant growth under N starvation.

To date, the role and mechanism of NaCl in accelerating tomato (<i>Solanum lycopersicum</i>) fruit coloring remain unclear. This study found that 50 mM NaCl treatment (moderate salt stress) reduced the chlorophyll content, increased the carotenoid and lycopene content, and accelerated tomato color transition without decreasing yield. Moreover, NaCl treatment downregulated <i>calmodulin-binding transcription activator</i> (<i>CAMTA5</i>)/<i>signal responsive</i> (<i>SR3</i>). Knockout of <i>SlSR3</i> by CRISPR/Cas 9 (<i>sr3</i> mutant) accelerated chlorophyll degradation and carotenoid and lycopene accumulation and upregulated chlorophyll degradation (<i>PPH</i>) and lycopene synthesis (<i>PSY2</i>, <i>PDS</i>, and <i>ZDS</i>) genes in tomato fruit, thereby accelerating tomato coloring. However, <i>SlSR3</i> overexpression had the opposite effect. Although NaCl treatment decreased chlorophyll, increased carotenoids, and upregulated <i>PPH</i>, <i>PSY2</i>, <i>PDS</i>, and <i>ZDS</i> in wild type and OE-<i>sr3</i> fruit, these changes were not observed in <i>sr3</i> mutant fruit. Therefore, <i>PPH</i>, <i>PSY2</i>, <i>PDS</i>, and <i>ZDS</i> might be involved in SR3-regulated coloring under moderate salt stress. Further results showed that SlSR3 could directly bind to the promoter of <i>PSY2</i> and <i>ZDS</i> via the CG-1 domain, thereby downregulating <i>PSY2</i> and <i>ZDS</i>. However, NaCl treatment reversed the transcriptional inhibition of SlSR3 on <i>PSY2</i> and <i>ZDS</i> expression, thereby upregulating <i>PSY2</i> and <i>ZDS</i>. Collectively, our results suggest that the promoting effects of NaCl on fruit coloring may be dependent on SlSR3-induced transcriptional regulation of lycopene synthesis-related genes <i>PSY2</i> and <i>ZDS</i>.
