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.

Commercial tree plantations cover around a million ha in Uruguay, mostly with stands of eucalypt and pine trees. Uruguayan forestry was relatively free of serious health threats until the end of the XX century. Beginning in the 90?s, both forestry area and international trade exhibited an exponential growth, soon followed by an increase of invasive insect records. More than half of the pests currently affecting Eucalyptus entered the country after 1995. The high percentage of plantation area currently under FSC and/or PEFC certification schemes (90%) restricted the use of pesticides and pushed the Uruguayan forestry to rely mainly on silvicultural and biological control to suppress insect pest outbreaks. However, there was almost no regulations regarding the use of biological control agents until the last decade, even when biological control for forest pests in the country can be traced back to the 1940s. Here, we present the state-of-the-art of biological control in Uruguayan commercial forestry. Currently, biological control with entomophagous or entomopathogenic organisms has been, or is currently being, implemented for eight insect pests. More than five parasitoid wasps and a nematode have been released and installed in the field. There are also at least two cases of adventive introduction of entomophagous organisms, simultaneously with the pest. Building capacity for biological control and improving the regulatory framework are key issues towards the success of biological control of forestry pests under the current pest scenario.
