Microbial diversity within early-stage cultured Panulirus ornatus phyllosomas

Article Abstract:

A study was conducted to characterize the microbial community associated with cultured, early-stage Panulirus ornatus phyllosomas and to determine microbial community changes over time. The findings reveal that colonization of phyllosomas with filamentous bacterial species hinders the ability of the animals to molt and combined with the added stress of the molt process resulted in reduced immune function allowing opportunistic pathogenic Vibrio sp. to cause larval mortalities.

Screening marine fungi for inhibitors of the [C.sub.4] plant enzyme pyruvate phosphate dikinase: Unguinol as a potential novel herbicide candidate

Article Abstract:

The screening of a collection of marine-derived fungi against the [C.sub.4] plant enzyme pyruvate phosphate dinase (PPDK) and the reliable scale-up production of a PPDK-selective inhibitor are described. Unguinol has deleterious effects on a model [C.sub.4] plant but no effect on a model [C.sub.3] plant, indicating that unguinol inhibits PPDK via a novel mechanism of action that also translates to an herbicidal effect on whole plants.

Identification of a ciliate (Oligohymenophorea: Scuticociliatia) associated with brown band disease on corals of the Great Barrier Reef

Article Abstract:

The ciliate associated with the coral disease brown band (BrB) is identified as a new species belonging to the class Oligohymenophorea, subclass Scuticociliatia, and is characterized by the presence of large numbers of intracellular dinoflagellates. The characteristic macroscopic signs of the coral disease BrB are attributed to the presence of a newly identified ciliate species of the class Oligohymenophorea, subclass Scuticociliatia.
