Secret plant

Trichodermaspecies have been investigated as biological control agents for over 70 years owing to their ability to antagonize plant pathogenic fungi. Mycoparasitism, one of the main mechanisms involved in the antagonistic activity ofTrichodermastrains, depends on the secretion of complex mix-tures of hydrolytic enzymes able to degrade the host cell wall. The antifun-gal activity of an a-1,3-glucanase (EC 3.2.1.59, enzymes able to degrade a-1,3-glucans and also named mutanases) has been described in T. harzia-num and its role in mycoparasitic processes has been suggested....

We used a proteomic approach to identify constitutively formed extracellu-lar proteins of Hypocrea atroviridis(Trichoderma atroviride), a known bio-control agent. The fungus was cultivated on glucose and the secretome was examined by two-dimensional gel electrophoresis.

Microbial biomass formation on root surfaces can be measured in plants growing in solution with or without an inert solid support. Carbon flow to the biomass can be measured by growing plants in solution or soil on a continuous source of 14C02 and the expected biomass formation predicted. The lack of correlation between measured and predicted biomass can be explained by oligotrophic growth of the micro-organisms.
