The microbial community of the coelomic fluid of the sea urchin Paracentrotus lividus

Characterization of the microbiota from coelomic fluid of the sea urchin Paracentrotus lividus

The study of the microbiota is a subject of considerable and growing interest since it is drawing new important perspectives in the life sciences concerning the functional relationships between metazoans and microbial cells. In fact, it has already shown that the endogenous microbial community affects various physiological activities of multicellular organisms. The coelomic cavity of echinoderms contains a fluid in which coelomocytes are reported to exert immune functions like phagocytosis, opsonization and production of antimicrobial agents against marine bacteria [1, 2]. However, up to day nothing is known about the endogenous bacterial population of coelomic fluid. We focused on this iss…

The seed endophytic microbiota of Citrus limon L. Burm. F

Background Plant seeds possess a complex microbiota which may play a crucial rolein a plethora of mechanisms, such as preservation, germination, seedling development, plant growth and health. In particular, seed endophytic microbiota is gaining more and more consideration due to the fact that it may be vertically transmitted to ensure individual competitive advantages. The Citrusspecies, including C.limon,areone of the most economically important evergreen fruit crops in the world. Objectives i)Identification and characterization ofmicrobial isolates from Citrus limon L. Burm. F. seed endosphere. ii) Structure of Citrus limon L. Burm. F. seed endosphytic microbiota. Methods -Surface-sterili…
