AB  - It has been explored to what extent the ratio of the two main fluorophores in honey, originating from proteins and phenolic compounds, change between the honey extraction stage and packaging in the jars. Fluorescence spectroscopy combined with multivariate curve resolution-alternating least squares (MCR-ALS) was used to determine the ratio of the spectral components originating from phenol and proteins (Ph/Pr)(fl) , as a ratiometric indicator of variability in selected Lime tree (Tilia L.) honey samples. Spectrophotometric quantification of phenols and proteins in the honey samples was also performed and their ratio (Ph/Pr)(sp) was calculated. The values of the (Ph/Pr)(fl) ratio and honey protein content after packaging depended on the quality of homogenization before packaging in jars. Colorimetric and fluorometric results for phenols and proteins were in compliance. The examples are the values 3.34, 3.30, and 9, 3.14 for (Ph/Pr)(fl) and corresponding values 2.64, 2.18, and 12.75, 2.31 for (Ph/Pr)(sp), in all pairs, the first value presenting the sample after extraction and the second value the sample after packaging in jars. Both methods show that in the former case there is no change in the phenol/protein ratio, and in the latter case the ratio decreased.

AB  - The aim of this research was to study phenolic compounds of diverse botanical species of wood commonly used in cooperage in Balkan countries. Several botanical species have been considered including mulberry (Morns alba L.), myrobalan plum (Prunus cerasifera Ehrh.), black locust (Robinia pseudoacacia L.), wild cherry (Prunus avium (L.) L.), and oak (Q. petraea (Matt.) Liebl., Q. robur L., and Q. terns L.). A total of 37 compounds were quantified, demonstrating the presence of phenolic acids, flavonols, flavones, flavanones, flavanonol taxifolin, stilbenoids, and coumarins. Taxifolin was the most abundant in wild cherry (8455.70 mg kg(-1)), while ellagic acid predominated in oak wood (8872.05-10099.32 mg kg(-1) in sessile oaks, and up to 15,958.80 mg kg(-1) in pedunculate oak from Slavonia). The highest content of protocatechuic acid (533.39 mg kg(-1)) was found in myrobalan plum. Also, isoflavones were characteristic of wild cherry, while mulberry was abundant in stilbenoids. Total phenolic content, as well as antioxidant, chromatic, and fluorescence properties were studied. The spectral shapes and maxima of fluorescence emission spectra of bare wood samples were compared with those of the corresponding wood extracts. The Principal Component Analysis (PCA) was applied in order to find patterns in emission spectra for differentiation among wood samples.

AB  - Rhinusa pilosa (Gyllenhal) is a highly specific weevil that induces stem galls on the common toadflax Linaria vulgaris Mill. females oviposit the eggs near the apex of a growing shoot. The act of oviposition is accompanied by secretion of an ovipositional fluid, which is considered to be cecidogen, directly involved in gall induction. The remains of cecidogenic fluid were collected from the surface of the oviposition point on the stem. We performed a comparative analysis of the phenolics extracted from cecidogen, the stem and galls of L. vulgaris and adult and larva of R. pilosa by HPLC-DAD. One compound with A (max) at 273, 332 nm (R (t) 30.65 min) was exclusively found in the methanol extract of cecidogen. To further characterize the cecidogen and stem phenolic profiles, we used UHPLC coupled with an OrbiTrap mass analyzer. Among 49 phenolic compounds extracted from both the ovipositional fluid and the plant, protocatechuic acid and two phenolic glycosides were exclusively found in cecidogen: diosmetin-O-acetylrutinoside and an unidentified compound. The unknown compound produced an MS2 base peak at 387 and 327 and 267 m/z base peaks at MS3 and MS4 fragmentation, respectively, and had the molecular formula C32H31O18. The plausible role of phenolic compounds in the induction of gall formation on L. vulgaris is discussed.

AB  - Background and Aims Retranslocation of iron (Fe) from source tissues enhances plant tolerance to Fe deficiency. Previous work has shown that silicon (Si) can alleviate Fe deficiency by enhancing acquisition and root to shoot translocation of Fe. Here the role of Si in Fe mobilization in older leaves and the subsequent retranslocation of Fe to young leaves of cucumber (Cucumis sativus) plants growing under Fe-limiting conditions was investigated. Methods Iron (Fe-57 or naturally occurring isotopes) was measured in leaves at different positions on plants hydroponically growing with or without Si supply. In parallel, the concentration of the Fe chelator nicotianamine (NA) along with the expression of nicotianamine synthase (NAS) involved in its biosynthesis and the expression of yellow stripe-like (YSL) transcripts mediating Fe-NA transport were also determined. Key Results In plants not receiving Si, approximately half of the total Fe content remained in the oldest leaf. In contrast, Si-treated plants showed an almost even Fe distribution among leaves with four different developmental stages, thus providing evidence of enhanced Fe remobilization from source leaves. This Si-stimulated Fe export was paralleled by an increased NA accumulation and expression of the YSL1 transporter for phloem loading/unloading of the Fe-NA complex. Conclusions The results suggest that Si enhances remobilization of Fe from older to younger leaves by a more efficient NA-mediated Fe transport via the phloem. In addition, from this and previous work, a model is proposed of how Si acts to improve Fe homeostasis under Fe deficiency in cucumber.
