NATURAL DEEP EUTECTIC SOLVENTS (NADES) IN SAMPLE PREPARATION OF PHOSPHATE ROCK AND MINERAL SUPPLEMENT FOR ELEMENTARY DETERMINATION BY PLASMA-BASED TECHNIQUES. Natural deep eutectic solvents (NADES) based on xylitol, citric acid, and malic acid were synthesized and used in ultrasound-assisted extraction (UAE) and heating-bath extraction of phosphate rock and mineral supplement samples. Arsenic, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, P and Zn were determined by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP OES). The results showed the NADES as promising solvents for extraction of inorganic matrices compared to reference values and concentrations obtained using microwave-assisted acid digestion (MW-AD). Significant differences were observed for some elements, suggesting different chemical interactions between the synthesized NADES and each monitored element. For analytes extraction of phosphate rock, UAE presented the best results for As, Cr and P. Zinc was extracted with UAE and heating bath. Concerning mineral supplement, no significant differences were observed for Ca (UAE), Cd (UAE and heating bath), K (UAE and heating bath), Mn (UAE and heating bath), Na (UAE and heating bath), and P (UAE and heating bath). The NADES is a greener and a potentially alternative for the sample preparation compared to the official methods of analysis, can being used as selective extractor solvent in conventional sample preparation methods.

Resistant and susceptible cotton cultivars were infected with Colletotrichum gossypii var. Cephalosporioides in order to identify differentially expressed transcripts associated to disease tolerance. Plants were grown in greenhouse and sprayed with a fungus suspension at 1 x 106 conidia mL-1. Young leaves were collected to total RNA extraction at 3 and 15 days after inoculation. For molecular procedures, 3 days after inoculation leaves-RNA were used to RT-PCR reactions, with ten pre-selected RAPD primers. Eight of these primers exhibited polymorphic bands and were selected for transcripts analysis. Differential expression was visualized in both cultivars in down and up regulations and also new apparently activated transcripts were registered. A transcript (200 bp) obtained from cv. resistant BRS Antares exhibited homology (86%) with the GmChl 3 gene (AB181949.1) that codifies to Chlorophyllase III in soybean plants. Dot blot analysis revealed that this transcript was over-expressed just in a resistant cv. Antares at 3 and 15 days after inoculation. |
