Abstract

The N.W. of Spain together with the North of Portugal are the European zones most affected by forest wildfires and they are within the worldwide areas with the most number of fires per ha and inhabitant (Carballas, 2007). In these and other countries wildfires are the main factor of forest ecosystems degradation mainly due to post-fire erosion and consequently they produce enormous ecological, social and financial damages. Therefore measures for fire prevention, fire fighting, post-fire soil protection and ecosystem recovery have to be taken. Modelling and knowledge-based systems are important tools for forest fire fighting which were successfully explored by our group (THOR GROUP) with this aim., We have first developed an Expert System, which comprises three computer tools: a) a Forest Fire Risk Index for fire prevention, that predict four days in advance (or more if reliable forecasts are available) the areas with risk of fire (four levels: low, medium, high and extreme risk) with 89% of fire estimation and less than 15% of overestimation; b) a System for the Management of the Resources for Fire Extinction, which gives the difficulty of fire control based on an algorithm that predicts fire propagation (rate and direction), establishes the fire level and produces a specific Plan for fire extinction; and c) a System for the Management of the Burnt Soils, which after analysing the fire damages on soil and plants, gives a plan for the immediate protection of the burnt soil and for the ecosystem recovery (Betanzos et al., 2003). Then, we has built: d) a Mathematical Model for the Prediction of the Forest Fires Peaks, which predicts three months in advance, with an error of no more than 3 days, the temporal period and the initiation date of the winter and the summer peaks, that usually are registered in Galicia (N.W. of Spain) and other regions, which is very important for the temporal contract of very expensive aerial resources; e) a Forest Fire Risk Index for Asturias (N of Spain); f) a Forest Fire Risk Index for Cantabria (N of Spain); and g) a Forest fire Risk Index based on satellite images (Sánchez et al., 2008)., The algorithms for the different systems were elaborated by using the historic forest fire and meteorological databases for more than 30 years, taking also into account structural characteristics. The models, as well as the corresponding GIS, initially made for the Galicia Community, were or can be adapted to other regions or countries having forest fire data registered for at least 10 years.

18. Introduction of p53 induces cell-cycle arrest in p53-deficient human medullary-thyroid-carcinoma cells

Abstract

The structural integrity of the p53 gene in a human thyroid-medullary- carcinoma-derived cell line has been studied. Analysis of high-molecular- weight DNA showed that the p53 locus is severely rearranged. PCR and single- strand conformation polymorphism analysis revealed that a large portion of the 5' end of the p53 gene is lost, while a region encompassing exons 8 and 9 is rearranged. As a consequence, no virtual expression of a p53-specific transcript is detected in mRNA from the medullary-carcinoma cell line. The absence of a p53 protein prompted us to analyze the biological effect of exogenous expression of this tumor-suppressor gene on cell growth and viability, introducing retroviral constructs carrying full-length human wild- type p53 cDNA. Contrary to what has been described for other cell types, including most thyroid-carcinoma cell lines of follicular origin, these experiments allowed us to establish clonal-cell populations which constitutively express p53. Cytometric analysis revealed G1-specific cell- cycle arrest, responsible for growth retardation in the transfected clones when compared with the parental cell line. However, medullary-thyroid- carcinoma cells expressing p53 are able to partially overcome the G1 block and progress through the cell cycle. In the search of the mechanism(s) involved in these processes, we describe the interaction of p53 with specific p21(WAFI/CipI) promoter sequences by gel-retardation assays.

19. Changes in auxin protectors and IAA oxidases during the rooting of chestnut shoots in vitro

Author

Mato, M. C., Viéitez Martín, Ana María, Mato, M. C., and Viéitez Martín, Ana María

Abstract

Auxin protectors and IAA oxidase activity were comparatively analyzed in the upper and the lower parts of shoots of chestnut (Castanea sativa Mill.) cultivated in vitro with indolebutyric acid (IBA) pretreatment. Rhizogenesis of the shoots is accompanied by an increase in auxin protectors in the lower parts and by a decrease of these protectors in the upper parts. Besides, the IAA oxidase activity declines in the basal parts during the rooting process while it increases in the upper ones. These biochemical events would enhance the IAA level in the rooting region of the shoots. In untreated, non‐rooted cuttings, the IAA oxidase activity remains low in the upper parts and high in the basal parts of the shoots. The results thus indicate that the IBA treatment may control the endogenous auxin level of the cuttings, either through a direct regulation of the IAA oxidase system or more indirectly through the transport of auxin protectors.
