ABSTRACT.
Accumulation of the red carotene pigment, lycopene, in Citrus fruit is an unusual feature restricted to grapefruit, pummelo and few orange mutants. Recent studies indicate that differential mechanisms may be operating in the different lycopene-accumulating varieties, highlighting the importance to understand these processes. It is well characterized in Citrus fruit that light positively affects color development and consequently carotenoid content and composition. However, it is paradoxical that by shading degreening of the red grapefruit ?Star Ruby? is accelerated and external color is enhanced (higher red coloration). To further understand the regulatory mechanisms of light on carotenoids biosynthesis in a lycopene-accumulating grapefruit, carotenoid composition and expression of related carotenoid biosynthetic genes were analyzed in the peel of shaded and light-exposed ?Star Ruby? grapefruit. The stage of fruit development at the time of shading appears to be influential in color development. In the peel of shaded fruits, total carotenoids (×4.5) and particularly lycopene (×14) and β-carotene (×4) experienced a dramatic increase. These changes were associated with a lower expression of early genes in the pathway as well as β-lycopene cyclase and β-carotene hydroxylase genes, envisaging their involvement in lycopene accumulation.

RESUMEN:
Se presenta un resumen descriptivo de cuatro encuestas llevadas a cabo en los años 2010, 2011, 2013, y 2018 en la cuenca lechera de Uruguay; con la participación de 22 técnicos en promedio/año; en hasta 7 departamentos, involucrando 312 tambos y 81.060 vacas masa. Se registró una consistencia de los índices reproductivos, con una disminución en el número de servicios por concepción y en el intervalo parto concepción en las vacas con el paso de los años. Se remarca la importancia de llevar registros para monitorear y mejorar la eficiencia reproductiva.
SUMMARY:
A descriptive summary of four surveys carried out in the years 2010, 2011, 2013, and 2018 in the dairy region of Uruguay is presented; with the participation of 22 technicians on average/year; in up to 7 departments, involving 312 dairy farms and 81,060 cows. A consistency of the reproductive indices over the years was observed with decreasing in the number of services per conception and in the interval calving to conception in the cows over the years.
The importance of keeping records for monitoring and improving reproductive efficiency is highlighted. |
