“…Numerous research papers on the introduction of exogenous iodine in plants have confirmed its positive effect on the antioxidant capacity in a plant (Blasco et al 2008(Blasco et al , 2011aMedrano-Macías et al 2016b). Among other things, the application of inorganic iodine in the form of I − and IO 3 − compounds in lettuce plants causes an increase of the content of phenolic compounds, ascorbic acid (Blasco et al 2008), glutathione, as well as catalase activity, whereas the IO 3 − form also improves the activity of superoxide dismutase (SOD) and ascorbate peroxidase (APX) (Blasco et al 2011a).…”

Iodine (I) is classified as a beneficial element for plants. Until now, there have been only hypotheses regarding the uptakes of organic iodine compounds by plant roots. The purpose of our research was to compare the uptakes and effects of the application of the following mineral and organic iodine compounds on young tomato plants: KI, 5-iodosalicylic (5-ISA), and 3,5-diiodosalicylic (3,5-diISA) acids. An additional control combination included the treatment with salicylic acid (SA) alone. All compounds were introduced into the nutrient solution in 5, 10, 25, and 50 μM I concentrations. It was established that after the application of 5-ISA and 3,5-diISA, iodine is taken up to a smaller extent than from KI. The tested KI, 3,5-diISA, and 5-ISA doses had no negative impact on the growth and development of plants, apart from the reduction of shoot biomass after the application of 3,5-diISA in 10 and 25 µM I doses. All applied compounds, except for SA, caused a reduction of ascorbic acid (AA) content and increase of dehydroascorbic acid (DHA) content in leaves. A significant increase of APX activity was noted only for the highest doses of KI and 5-ISA. None of the iodine compounds, in most tested doses, have substantially increased the CAT and POX activities in tomato leaves. Application of KI decreased the levels of all analyzed sugars in tomato leaves. The effect of iodosalicylates on sugar content varied depending on the compound: when applied in the highest dose 5-ISA increased, while 3,5-diISA decreased the sugar accumulation in tomato plants. In all tested treatments, a reduction of SA content in leaves was noted. We conclude that organic iodine compounds, i.e., 3,5-diISA and 5-ISA, can be taken up by the roots of tomato plants at an early stage of development.

“…Iodine reduction by H 2 O 2 is widely described in the literature. 43,44 In vitro this process leads to the direct formation of HOI 45 and other species via unstable intermediates. 46 For this purpose, we decided to study whether 125,131 I can be efficiently released from the NP surface under highly oxidative conditions corresponding to hepatic cancer cells (Fig.…”

“…La suplementación con yodo de los alimentos o la biofortificación de alimentos de origen vegetal es una alternativa para mantener la ingesta de yodo y reducir el consumo de sal de mesa. La ventaja de la biofortificación es que el yodo se encuentra en formas orgánicas que tienen mayor biodisponibilidad y estabilidad contra la volatilización que las formas de sal inorgánica; otra ventaja de la biofortificación es que se puede aplicar a cultivos de consumo frecuente o tradicionales en ciertas regiones (Medrano et al 2016a).…”

El yodo es un elemento esencial para los humanos pues su déficit puede afectar la salud humana. Los complejos de quitosán yodados en frutos pueden ser una buena alternativa para mejorar la biofortificación, además de aumentar el rendimiento y la calidad del cultivo. Por lo que el objetivo de este trabajo fue evaluar el efecto poscosecha sobre los principales compuestos nutraceúticos (incluyendo antioxidantes) de frutos de melón por efecto de la aplicación de compuestos biofortificantes de yodo en estadios precosecha. Los tratamientos aplicados fueron a base de sales de yoduro de potasio (KI) y yodato de potasio (KIO3), complejo quitosán-KI (CS-KI), complejo de quitosán-KIO3 (CS-KIO3), quitosán como control y agua como testigo absoluto en frutos de melón. Cada tratamiento consistió en dosis de 5 y 25 mg Kg-1 asperjado de manera foliar. Los resultados muestran que la aplicación de complejos de CS-I mantiene la calidad y disminuye la apariencia de deshidratación durante 15 días poscosecha, el contenido de carotenoides en frutos tratados (promedio 446.67 mg 100 mL-1) es mayor en comparación con los frutos control (promedio 230.65 mg 100 mL-1) a los 12 días, el contenido de la vitamina C en frutos tratados (promedio 46.56 g 100 mL-1) es mayor en comparación con los frutos control (promedio 35.93 g 100 mL-1) a los 10 días y la capacidad antioxidante total se mantiene (promedio 44.47 µg EAG mL-1) durante 15 días de almacenamiento, lo que indica la conservación del contenido nutracéutico del melón por hasta 15 días a 25 °C.
