.... exhibiting a nearly immediate increase of ROS. Differences in symbiont type may explain the greater sensitivity of colonies of Sarcothelia sp. Using fluorescent probes, direct measurements of migrating symbionts in the stolons of Sarcothelia sp. showed higher levels of reactive nitrogen species and lower...

... physical regression and the abundance of associated reactive oxygen species. Caspase inhibitors also altered cellular ultrastructure, resulting in features suggestive of necrosis rather than apoptosis. At the same time, caspase inhibitors had little effect on reactive nitrogen species that are also...

... in a few stolons of a normally growing colony. For detailed studies, many stolons of a colony can be induced to regress by pharmacological manipulations of reactive oxygen species (e.g. hydrogen peroxide) or reactive nitrogen species (e.g. nitric oxide). The regression process begins with a cessation...
