Cut lisianthus (Eustoma grandiflorum) is an appealing and popular multiflorous inflorescence, but its florets leaves tend to wilt rapidly quickly lose their freshness. In this study, considering typical water- sugar-deficiency symptoms, the potential benefits of vase treatments with nano-silver (NS) sucrose on improving performance cut 'Lucetta' were investigated. Compared control in deionised water, 2.0 mg/L NS or 3% alone could only moderately prolong life lisianthus, whereas combination treatment significantly prolonged life. Additionally, demonstrated notable synergistic effects daily opening rate florets, ornamental value, solution uptake, relative fresh weight, markedly enhancing performance. Further scanning under electron microscope revealed that effectively reduced bacterial cells biofilm formation stem-end surfaces xylem vessels stem-ends, water was invaded by a deep layer bacteria, extensively blocked mass bacteria.

Utilizing microalgae as "photosynthetic cell factories" for compound production holds significant potential sustainable carbon neutrality. However, the inherent inefficiency of algal photosynthesis, a limiting factor productivity, represents critical area enhancement. Among key regulatory mechanisms, Target Rapamycin (TOR), essential growth regulation and known its conserved structure across eukaryotes, remains underexplored in Nannochloropsis gaditana. In this study, we identified component TOR complex N. (RAP) effectively inhibited photosynthetic enhanced lipid accumulation gaditana, demonstrated by sensitivity tests. Transcriptomic analysis revealed that NgTOR modulates multiple intracellular metabolic signaling pathways. Specifically, genes associated with photosynthesis chlorophyll synthesis were significantly down-regulated following inhibition. Additionally, involved metabolism, TCA cycle, amino acid biosynthesis markedly reduced, while those related to metabolism up-regulated, resulting stunted increased accumulation. Furthermore, blocking DCMU reduced transcriptional activity TOR-related complexes, highlighting bidirectional interaction. These findings underscore pivotal role pathway regulating setting stage further studies on autotrophy pathways species.

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.

As sessile photoautotrophs, plants constantly encounter diverse environmental stresses. Recent research has focused on elucidating sugar and energy signaling mediated by hexokinase (HXK), sucrose non-fermenting 1-related protein kinase 1 (SnRK1), the target of rapamycin (TOR) assessing its intricate interplay with hormones secondary metabolism. HXK serves as a pivotal regulator glucose sensing It affects plant growth development in response to nutrient availability. SnRK1 acts vital sensor that regulates metabolic adjustments during stress bolster resilience. Moreover, TOR integrates signals finely modulate development, balancing cellular metabolism resource allocation. Understanding functions HXK, SnRK1, can provide profound insights into adaptation mechanisms open promising avenues for leveraging biotechnological strategies enhance tolerance nutritional value crops.

Summary Global models of vegetation dynamics are largely carbon (C) source-driven, with behaviour primarily determined by the environmental responses photosynthesis. However, real plants operate as integrated wholes, feedbacks between sources and sinks resulting in homeostatic concentrations metabolites such sugars. An approach to implementing a plant growth model is presented its implications for generic factors assessed. The based on Hill functions representing inhibition C (net photosynthesis) activation (structural growth) sugar concentrations. parameterised mature tropical rainforest site qualitative found be consistent experimental observations. Key findings that strongly regulate each other. For example, doubling potential net photosynthesis (i.e. rate would occur without feedback) results increasing only 1/3 at equilibrium, increased concentration causing feedback-inhibition A source-only driven response, current global models, result close growth. Hence affect photosynthesis, atmospheric CO 2 , have greatly reduced effects when sugars considered. considering source-sink coupling likely profound.

Rose (Rosa rugosa) is an important perfume plant, but its cultivation significantly constrained by salt stress. Terpenes represent the most abundant volatile aromatic compounds in roses, yet little known about how terpene metabolism responds to In this study, salt-treated rose petals presented significant accumulation of monoterpenes, including geraniol, due disruption jasmonic acid (JA) biosynthesis and signalling. Overexpression silencing analyses revealed a MYC transcription factor involved JA signalling (RrbHLH105) as repressor geraniol biosynthesis. RrbHLH105 was shown activate trehalose-6-phosphate synthase genes RrTPS5 RrTPS8 binding E-box (5'-CANNTG-3'). The increased content decreased overexpressing TPS5 or RrTPS8, along with high where both TPSs were cosilenced, indicate that trehalose plays role negative regulation via RrbHLH105-TPS module. summary, suppression stress leads excessive through inhibition RrbHLH105-mediated RrTPS-mediated petals. Additionally, study highlights emerging critical integrator crosstalk.
