Mol Gen Genet. The thermotaxis of the plasmodium is so strong and the organism without learning always proceeds to the higher temperature region. The “acellular” moniker derives from the plasmodial stage of the life cycle: the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a network of interlaced tubes.

Our online platform, Wiley Online Library (wileyonlinelibrary.com) is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities. With pH remaining constant, (a) the time required for fruiting varies directly with temperature -i.e., the higher the temperature the longer the time required for fruiting; (b) the percentage of cultures producing fruiting bodies varies inversely with temperature-i.e., the higher the temperature, the smaller the percentage fruiting. AJB publishes peer-reviewed, innovative, significant research of interest to a wide audience of scientists in all areas of plant biology (e.g., biodiversity, structure, function, development, genetics, evolution, reproduction, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, algae, fungi, and lichens).
