A diverse range of plant proteases are implicated in pathogen perception and in subsequent signalling and execution of disease resistance. We demonstrate, using protease inhibitors and virus-induced gene silencing (VIGS), that the plant papain cysteine protease cathepsin B is required for the disease resistance hypersensitive response (HR). VIGS of(More)
This paper presents original results on the Sb and heavy metals contents in sediments and waste tailings, plants and water from the giant Wadley antimony mine district (San Luis Potosí State, Mexico). The dominant antimony phases in mining wastes are stibiconite, montroydite and minor hermimorphite. The waste tailings contain high concentrations of metals(More)
The Coiba National Park is located off the Pacific coast of Panama andincludes several small islands and a larger one which gives its name to the park. Anumber of rivers in Coiba Island have well developed mangrove systems attheir mouths and two of these were selected for the present study: SantaCruz and El Gambute. The first one comprises an assemblage of(More)
This paper describes the pre-operational analysis and forecasting system developed during MACC (Monitoring Atmospheric Composition and Climate) and continued in the MACC-II (Monitoring Atmospheric Composition and Climate: Interim Implementation) European projects to provide air quality services for the European continent. This system is based on seven(More)
Santa Cruz and El Gambute, two mangrove systems with associated tidal flats, were sampled in Coiba National Park, Coiba Island, Pacific of Panama. At each site, two samplings were done at low, middle and high intertidal levels in February and November of 1997. A new orbiniid species were found: Orbinia oligopapillata n. sp. is characterized by having 15-16(More)
The global NaGISA (Natural Geography in Shore Areas) initiative focusing on long-term monitoring of coastal biodiversity has recently been expanded to the Mediterranean. On the basis of datasets from four Mediterranean hard substrate sites and by using the most abundant polychaete family (Syllidae), two questions are addressed in this study: (a) Is the(More)
This is the second paper on the Syllidae (Polychaeta) from hard substrata of the Coiba National Park (Pacific coast of Panama) (the first paper treated Syllinae). On this second paper nineteen species belonging to eleven genera of the subfamilies Autolytinae, Eusyllinae and Exogoninae (Syllidae: Polychaeta) are reported. The samples were collected by SCUBA(More)
During a study carried out on the subfamily Exogoninae (Syllidae) from Australia, several specimens of a new genus and species were found in samples of dead coral substrate from Western Australia. They have long palps, fused except for a terminal notch, long median and two short lateral antennae, a single pair of short tentacular cirri, and short dorsal(More)
Four expeditions were made to Coiba National Park between 1996 and 1998 to characterize this part of the poorly known Panamian Pacific polychaete fauna. The samples were collected by SCUBA diving, either by removing 4 kg blocks of dead coral (Pocillopora sp.) or scraping off 25 x 25 cm quadrats of Telesto multiflora or algae (Dyctiota cf. flavellata, Padina(More)
During the Antarctic summers of 2002–2003 and of 2005–2006, the Spanish BENTART cruises were conducted to the Bellingshausen Sea (Western Antarctica), aiming to study its benthic communities, from depths ranging from 100 to 2,000 m. To achieve it, 30 stations were selected; each one was surveyed in such a way that the infaunal, epifaunal and suprabenthic(More)
