“…seem to be very common in northern Z. marina beds [62]. This implies that L. zosterae may not be pathogenic under non-or low-stress conditions [60,63,64], possibly as a result of low pathogenicity, a strong defence reaction of the host, or both. Given our finding of additional putative pathogens in Z. marina beds, we may have to revisit the pathology of Z. marina, and perhaps also of seagrasses in general.…”

Phytophthora species are potent pathogens that can devastate terrestrial plants, causing billions of dollars of damage yearly to agricultural crops and harming fragile ecosystems worldwide. Yet, virtually nothing is known about the distribution and pathogenicity of their marine relatives. This is surprising, as marine plants form vital habitats in coastal zones worldwide (i.e. mangrove forests, salt marshes, seagrass beds), and disease may be an important bottleneck for the conservation and restoration of these rapidly declining ecosystems. We are the first to report on widespread infection of Phytophthora and Halophytophthora species on a common seagrass species, Zostera marina (eelgrass), across the northern Atlantic and Mediterranean. In addition, we tested the effects of Halophytophthora sp. Zostera and Phytophthora gemini on Z. marina seed germination in a full-factorial laboratory experiment under various environmental conditions. Results suggest that Phytophthora species are widespread as we found these oomycetes in eelgrass beds in six countries across the North Atlantic and Mediterranean. Infection by Halophytophthora sp . Zostera, P. gemini , or both, strongly affected sexual reproduction by reducing seed germination sixfold. Our findings have important implications for seagrass ecology, because these putative pathogens probably negatively affect ecosystem functioning, as well as current restoration and conservation efforts.

“…1 & 2). This is supported by Vergeer et al (1995) who concluded that a decrease of total phenolic compounds in the tissue of Z. marina indicated plants may be growing in unsuitable environmental conditions. Noteworthy is that correlation analysis indicated a significant (p< 0.05) inverse relationship between heavy metal content and the health of plants as measured by phenolic content for P. oceanica (r 2 = 69.8 %, linear model of regression: mercury = 0.22 -0.0055 * phenol for sheaths).…”

“…Plants have developed chemical defenses against invasion of microorganisms. Vergeer et al (1995) reported that the production of phenolic compounds in Z. marina L. increased when infected by Labyrinthula zosterae, indicating that the production of phenolic compounds is an antimicrobial response. In marine plants, bioactive chemicals such as phenolic compounds play important roles for plant survival and growth, and are now being used to explore new drugs and health foods for human (Baker and Joseph, 1984;Smit, 2004;Katalinic et al, 2006).…”

Zostera marina L. is one of marine flowering plants, which plays an important role in coastal ecosystems by generating oxygen and organic substance and providing a habitat for other organisms. However, its residues on seashore have caused serious environmental problems in some coasts worldwide. In this paper, crude extract of Z. marina L. was prepared using methanol-water (1:1, v/v) and further separated into petroleum ether fraction, ethyl acetate fraction, n-butanol fraction and water fraction. The antibacterial activity and antioxidant activity of different fractions from Z. marina L. were evaluated in order to provide information for utilizing the marine plant. Antibacterial bioassay showed that n-butanol fraction was effective only for Staphylocccus aureus, petroleum ether fraction was effective for S. aureus and Bacillus anthracis, ethyl acetate fraction was effective for S. aureus, B. anthracis, Diphtheroid bacilli and Staphylococcus epidermidis, while water fraction had no effect on all the tested strains. Antioxidant assay indicated that all of the four fractions showed α-diphenyl-β-picrylhydrazyl (DPPH) radical-scavenging activity and Fe 3+ reducing activity, and ethyl acetate fraction exhibited the maximum activity.
