Abstract	A novel type of emulsifiers (STOC- SAC0, SAC8 & SAC12) were synthesized from nature-abundant cellulose by a two-step process: preparartion of soluble cellulose by TEMPO-mediated oxidation of cellulosic nanocrystal and fractionation (STOC), and introduction of hydrophobic moiety by alkyl (C0, C8 & C12)succinylation of resulting soluble polysaccharides. The synthetic products were structurally verified by Fourier Transform Infrared (FT-IR), Nuclear Magnetic Resonance (NMR) and Gel Permeation Chromatography (GPC). The surface-active property and functionality of the new ingredients were characterized by determinations of contact angle, ABTS radical scavenging and Ferrous chelating ability, and their performance as new ingredient; which demonstrated that alkylsuccinylated soluble TEMPO-oxidized celluloses (STOC-SACx) have unique multi-purpose functionalities: emulsifying, stabilizing and antioxidant property. STOC-SAC12 displayed the best surface activity with the lowest contact angle (18° on a hydrophobic surface basis) and the highest antioxidant properties (compared to succinylated cellulose (C-SAC0) the ABTS radical scavenging and Fe²⁺ chelating property of STOC-SAC12 are significantly higher by 10-fold and 4.5-fold, respectively); accordingly STOC-SAC12 also resulted in the most stable homogeneous fish oil-in-water nanoemulsion with a mean droplet size of 200 nm, polydispersity index of 0.18 and ζ-potential up to −90 mV; evidenced by scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLFM) and dynamic light scattering analyses. In short this work reported a industry-feasible and fully scalable approach to transform abundant renewable plant cellulose into novel ingredients with unique fucntionalities which could find potential application in delivery of oxidation-prone bioactives through complicated emulsion systems.

Abstract	To seek for novel effective low-energy renewable stabilizer for food emulsion system, this work reported the preparation of water-insoluble nanocellulose fraction from TEMPO (2, 2, 6, 6-Tetramethylpiperidine 1-oxyl) mediated oxidation, and its application as an excellent low-energy stabilizer in Pickering emulsion. The obtained Insoluble TEMPO-mediated Oxidized Cellulose (ITOC) from sequential processes by TEMPO-mediated oxidation, fractionated by centrifugation, dialysis and freeze drying, afforded high oxidation degree (25.12 ± 2.57 %), high carboxylate content (1.47 ± 0.14 mmol COO⁻/g), and low contact angle (27.5 ± 0.1°). The impact of ITOC dosages and oil contents on the fabrication and stabilization of Pickering emulsion was investigated. A lower dosage of ITOC (0.9 %, wt %) afforded to stabilize concentrated Pickering emulsion (50 wt % oil content) with smaller average droplet size (about 1400 nm). High storage stability and the stability against environmental stress saline conditions (100–200 mmol/L), both neutral and basic conditions (pH 7–11) and a broad range of temperatures (30–90 °C) was found. As a novel kind of low-energy biomass-based particle stabilizer, ITOC might have great potential for industrial applications in food and related sectors.

Abstract	The aim of this study was to develop a novel dual-functional stabilizer for food-grade Pickering emulsions by grafting caffeic acid onto chitosan via a free radical mediated method. The grafting of caffeic acid onto chitosan was confirmed by UV–vis absorption spectra, FTIR spectra and 1H NMR spectra and DSC thermogram. The antioxidant properties of the caffeic acid grafted chitosan (CA-g-Ch) were measured by three in vitro assays. Caffeic acid-grafted chitosan displayed much better Fe2+ chelating property than both chitosan and caffeic acid, and retained comparable DPPH radical scavenging activity as caffeic acid. Moreover, the formation of the CA-g-Ch based emulsion was monitored by the turbidity, zeta potential, and particle size measurements. The CA-g-Ch polymers were found to be pH-responsive. The oil (linoleic acid) in water emulsions with the CA-g-Ch (as emulsifier/Pickering stabilizer) was prepared to examine its potential to stabilize Pickering emulsions, as well as its additive antioxidant properties. The results (zeta potential, mean droplet size, creaming index and TBARS values etc) demonstrated that the CA-g-Ch could act as a dual-functional stabilizer for Pickering emulsions. The emulsions made with the CA-g-Ch were found to be stable at a broad pH range of 3–6. Our findings proved that CA-g-Ch as novel dual-functional polymeric surfactant, may have great potential to find applications in food and pharmaceutical industries.

Abstract	Nitrogen-fixing nodules are new organs formed on legume roots as a result of the beneficial interaction with the soil bacteria, rhizobia. Proteins of the nitrate transporter 1/peptide transporter family (NPF) are largely represented in the subcategory of nodule-induced transporters identified in mature nodules. The role of nitrate as a signal/nutrient regulating nodule functioning has been recently highlighted in the literature, and NPFs may play a central role in both the permissive and inhibitory pathways controlling N

Abstract	Symbiotic nitrogen fixation in legumes requires nodule organogenesis to be coordinated with infection by rhizobia. The plant hormone auxin influences symbiotic infection, but the precise timing of auxin accumulation and the genetic network governing it remain unclear. We used a Lotus japonicus optimised variant of the DII‐based auxin accumulation sensor and identified a rapid accumulation of auxin in the epidermis, specifically in the root hair cells. This auxin accumulation occurs in the infected root hairs during rhizobia invasion, while Nod factor application induces this response across a broader range of root hairs. Using the DR5 auxin responsive promoter, we demonstrate that activation of auxin signalling also occurs specifically in infected root hairs. Analysis of root hair transcriptome data identified induction of an auxin biosynthesis gene of the Tryptophan Amino‐transferase Related (LjTar1) family following both bacteria inoculation and Nod factor treatment. Genetic analysis showed that both expression of the LjTar1 biosynthesis gene and the auxin response requires Nod factor perception, while common symbiotic pathway transcription factors are only partially required or act redundantly to initiate auxin accumulation. Using a chemical genetics approach, we confirmed that auxin biosynthesis has a functional role in promoting symbiotic infection events in the epidermis.

Abstract	Legume-rhizobium signaling during establishment of symbiotic nitrogen fixation restricts rhizobium colonization to specific cells. A limited number of root hair cells allow infection threads to form, and only a fraction of the epidermal infection threads progress to cortical layers to establish functional nodules. Here we use single-cell analysis to define the epidermal and cortical cell populations that respond to and facilitate rhizobium infection. We then identify high-confidence nodulation gene candidates based on their specific expression in these populations, pinpointing genes stably associated with infection across genotypes and time points. We show that one of these, which we name SYMRKL1, encodes a protein with an ectodomain predicted to be nearly identical to that of SYMRK and is required for normal infection thread formation. Our work disentangles cellular processes and transcriptional modules that were previously confounded due to lack of cellular resolution, providing a more detailed understanding of symbiotic interactions.
