However, the contradictory results of the present in vitro and in vivo studies, suggests that assaying virulence of facultative pathogen mycobacteria based only on in vitro studies should be done with some caution.
Just like in the case of the bacterial set, there are several positions in the core region and at the facultative base positions where the AEVs are higher than average, yet no identity element has been published.
Raven, A. et al. Cholangiocytes act as facultative liver stem cells during impaired hepatocyte regeneration.
The paper presents a very extensive evaluation of the coliform decay in facultative and maturation ponds, based on data from 186 different ponds in the world.
Vernalization saturation is the expression of sufficient Vrn1 and this will eventually occur in all facultative wheat plants due to low base expression.
Based on larval skeleton measurements, the facultative feeding period of larvae was estimated in 5 clypeasteroid species [13].
The identified four subphyla (based on 18S rRNA gene sequences) of facultative anaerobic fungi, the Agaricomycotina, Mucoromycotina, Pucciniomycotina and Saccharomycotina, as well as the identified species from the genera Mucor and Saccharomyces (Table 1) were shown to be consistently present within the highly diverse reactor community of BP1 over the period of more than 1 year [19].
Similar to saprophytic fungi, facultative fungal pathogens can be divided into two groups based on the number and type of CAZymes.
One of them (group B1) was positioned at the base of the tree and contained some few bacterial facultative and obligate parasitic lineages (e.g., Chlrorobium, Candidatus Sulcia, and Candidatus Carsonella).
In addition, the different populations used between studies may harbor different populations of facultative endosymbionts, as some endosymbionts are either lost or obtained based on environmental conditions and horizontal transmission [81].
The evidence of facultative anaerobic fungi in the studied biogas reactor of BP1 was based on their intensive fluorescence and the cell size and was demonstrated further by the presence of fungal 18S rRNA gene sequences.
