Aspergillus flavus is unique in that it is a thermotolerant fungus, so can survive at temperatures that other fungi cannot. [12] [13] A. flavus can contribute to the storage rots, especially when the plant material is stored at high moisture levels. A. flavus grows and thrives in hot and humid climates. [10]
In March 2010, Aspergillus covered 837 species of fungi. [5] Notable species placed in Aspergillus include: Aspergillus flavus is a notable plant pathogen impacting crop yields and a common cause of aspergillosis. Aspergillus fumigatus is the most common cause of aspergillosis in individuals with an immunodeficiency.

The fungus was originally classified as a subspecies of A. flavus called Aspergillus flavus subsp. parasiticus (Speare) due to its strong resemblance to A. flavus. Indeed, this fungus is very closely related to A. flavus [3] and is often misidentified as the latter. [3] However, the two species are separable based on morphological features. [3]
Thirdly, plant morphology studies plant structure at a range of scales. At the smallest scales are ultrastructure, the general structural features of cells visible only with the aid of an electron microscope, and cytology, the study of cells using optical microscopy. At this scale, plant morphology overlaps with plant anatomy as a
Aflatoxin M 1 is a chemical compound of the aflatoxin class, a group of mycotoxins produced by three species of Aspergillus – Aspergillus flavus, Aspergillus parasiticus, and the rare Aspergillus nomius – which contaminate plant and plant products. Aspergillus flavus produces only B-type aflatoxins.
The sequenced strain isolated in 1950 is called RIB40 or ATCC 42149; its morphology, growth, and enzyme production are typical of strains used for sake brewing. [28] The increased number of genes in Aspergillus oryzae are responsible for the function of proteins and cellular processes such as hydrolase, transporters, and metabolism. The ...
Aflatoxin B 1 is an aflatoxin produced by Aspergillus flavus and A. parasiticus.It is a very potent carcinogen with a TD 50 3.2 μg/kg/day in rats. [4] This carcinogenic potency varies across species with some, such as rats and monkeys, seemingly much more susceptible than others.
