Auxin and insulin promote Zea mays embryo growth, induce S6 ribosomal protein (S6rp) phosphorylation, and promote specific protein synthesis. The objective of this research was to test a possible cross-talk between insulin and auxin transduction pathways in Z. mays coleoptiles, typical auxin target tissues. Auxin and insulin produced differential quantitative and qualitative stimulation of cytoplasmic and ribosomal protein phosphorylation, and specific patterns of de novo synthesized cytoplasmic proteins. In addition, insulin induced S6rp phosphorylation was strongly inhibited by rapamycin, indicating target of rapamycin (TOR) kinase participation; auxin-induced S6rp phosphorylation was insensitive to this inhibitor. Phosphatidic acid (PA), a second...

Cactus stems, the cladodes of Opuntia spp. cacti, are consumed in Mexico and other countries due to their fresh and herbaceous flavor, and because of their widely known nutraceutical benefits. In order to extend the postharvest life of this vegetable, the effect of a modified atmosphere packaging (MAP) was studied in cactus stems of the cultivar Atlixco stored at 4 ± 1 °C for 20 days under three types of atmospheres: (1) air (passive atmosphere), (2) 5 kPa O2 + 4 kPa CO2, and (3) N2. During storage, the titratable acidity decreased and the color of cladodes became darker and less green; however, the 5 kPa O2 + 4 kPa CO2 atmosphere was able to preserve both quality characteristics. All modified atmospheres reduced weight loss (from 8 to &lt;2%) and the...

Carotenoides, capacidad antioxidante y compuestos volátiles del aroma durante la maduración de jitomate
Provedor de dados: 85

El jitomate acumula altos niveles de carotenoides durante su maduración. Éstos, además de su función como pigmentos, nutrientes y antioxidantes, son precursores de algunos compuestos volátiles importantes en el aroma de estos frutos. Por ello, en este trabajo se estudió la capacidad antioxidante, los niveles de licopeno y &amp;#946;-caroteno y la producción de sustancias aromáticas provenientes de la vía de carotenoides en frutos de jitomate de la variedad 7705, en diferentes estados de maduración. Los resultados mostraron un aumento significativo (p&lt;0,05) de licopeno y &amp;#946;-caroteno (22,1 y 2,9 veces, respectivamente) desde el estado de madurez verde al rompiente. Entre los estados de madurez naranja y rojo, los niveles de licopeno se...
