| rapid identification of cyst (heterodera spp., globodera spp.) and root-knot (meloidogyne spp.) nematodes on the basis of its2 sequence variation detected by pcr-single-strand conformational polymorphism (pcr-sscp) in cultures and field samples. | cyst and root-knot nematodes show high levels of gross morphological similarity. this presents difficulties for the study of their ecology in natural ecosystems. in this study, cyst and root-knot nematode species, as well as some ectoparasitic nematode species, were identified using the second internal transcribed spacer (its2) sequence variation detected by polymerase chain reaction-single-strand conformational polymorphism (pcr-sscp). the its2 region was sufficiently variable within the taxa i ... | 2000 | 10972762 |
| water sources and water-use efficiency in mediterranean coastal dune vegetation. | in coastal environments plants have to cope with various water sources: rainwater, water table, seawater, and mixtures. these are usually characterized by different isotopic signatures ( (18)o/ (16)o and d/h ratios). xylem water reflects the isotopic compositions of the water sources. additionally, water-use efficiency (wue) can be assessed with carbon isotope discrimination (delta) analyses. gas exchange, delta of leaf dry matter, and isotopic composition (delta (18)o) of xylem water were measu ... | 2004 | 15143444 |
| first report of longidorus kuiperi and rotylenchus eximius from coastal sand dunes in crete, greece. | plant-parasitic nematode species have been reported on several occasions from coastal sand dunes, including longidorus and rotylenchus species (vovlas et al., 2008; de luca et al., 2009; mateille et al., 2014). in april 2016, 10 soil samples of 3 to 4 kg from the rhizosphere of tamarix smyrnensis with different vegetation around (viz. elymus farctus, lycium schweinfurthii, crithmum maritimum, and arthrocnemum sp.) were collected for diagnosis of plant-parasitic nematodes. the area of sampling wa ... | 2016 | 27765985 |
| effects of posidonia oceanica beach-cast on germination, growth and nutrient uptake of coastal dune plants. | seagrass meadows play an important role in marine ecosystems. a part of seagrass production is also exported to adjacent coastal terrestrial systems, possibly influencing their functioning. in this work we experimentally analyzed the effect of posidonia oceanica beach-cast on plant germination, growth, and nutrient uptake of two plant species (cakile maritima and elymus farctus) that grow on upper beaches and fore dunes along the mediterranean coasts. we compared plants growing in simple sand (c ... | 2013 | 23894678 |
