Gilles, thank you very much for your valuable work! I just wonder why you have tagged the spores with 'α' and 'a' at 8:51 as if each of them was identical to one of their parents? If the nuclei fuse together, should the resulting spores not have different sets of (genetic material from both parents, shuffled) chromosomes? A similar situation is with the color coding used at 4:55. Why are there two groups of four similarly colored spores and not four groups of spores with different orange color tones each having two identical members?

Dear Tubetolombe, Based on my research for the video, 'alpha' and 'a' is standard for denoting to different yeast cells. Remember, they are both haploid; and yes they are genetically similar to their parent cell. They are the product of fission, and are thus clones of their parents. But 'alpha' and 'a' are different from each other. That is 'alpha' has a set of alleles that are different from those in 'a'. When 'alpha' and 'a' fuse together, the result is a diploid 'alpha'/'a' cell. This cell will undergo two rounds of meiosis to rearrange the genes and give off 4 genetically distinct haploid daughter cells. Your point of coloring these final daughter cells different shades of orange is a good idea. I will keep this in mind for the next video to show differences in genetic make up. Thank you for your comment and I hope this clarifies your questions.

I have a question what is the best example of the ascomytota? saccaharomyces cereviase, all of them, aspergillus, or penicillium?
@ProfGillesBolduc 7 жыл бұрын
The best example of an ascomycota fungi would be the Peziza because the ascus are fully formed and easy to recognize.

1:35 I’d like to correct your statement that these molds aren’t known to be a health concern other than their pathogenicity to the immunocompromised: There are common species of Aspergillus that are known to carry mycotoxins, most commonly Aflotoxin. These are potent toxins that can cause a wide range of debilitating issues in animals ands humans from contaminated foods.
@redding4540 7 жыл бұрын
you should change the 2 colors into single color because those 8 fused haplods are identical after mitosis. I know you are out of space but it will lead us into confusion. Also meiotic division leads 4 haploids...and then 8 haploids by mitotic division.
@ProfGillesBolduc 7 жыл бұрын
Thank you for picking up on this. I made an annotation regarding the meiotic division followed by mitosis. I cannot change the colors without making a new video, but I would like to understand your concern. Are you talking about the final 8 ascospores. I don't believe they are identical since they just underwent meiosis. Can you please clarify which 8 haploids your are referring to? Thanks, Gilles

Dear Kyu rA, can you please ask the question differently? I'm not sure if I understand it correctly. Each generation is one complete life cycle.

Gilles Bolduc i want to know what type is the life cycle of aspergillus ( sexuel reproduction) like if its two generations (the one who gives gamits n nd the sporophyte 2n ) or if its a three generations and thank you in advance

isn't penicilium deuteromycotina?
@ProfGillesBolduc 4 жыл бұрын
Deuteromycotina (a.k.a. Deuteromycota) is a phylum that mycologists group fungi with no known sexual reproduction. As they learned more about the members, usually by DNA analysis, theses members are moved out of the Deuteromycota phylum and placed in their correct phylum. The interesting thing is that the majority are placed into the Ascomycota phylum. I suspect this is what happened to Penicillium.

@@ProfGillesBolduc yeah, no, im aware that 'fungi imperfecti' usually turn out to be ascos, its just that im studying for my micology final and my recently published textbook inexplicably puts penicillium in the deuteromycoyina subphylum

I wish I can help you more than this. But this is what I learned from my research. Go with what your textbook tells you for your final exam and ask your professor for his/her thoughts. (It could score you some points!) I'm hoping he/she is a mycologist and thus knows more than I. I'm a bacteriologist. Please let me know what they say. Good luck on your final exam.

@@ProfGillesBolduc so i think i figured out why i was confused, the textbook mentions only the anamorphic phase of penicillium in relation to the subphylum deuteromycotina... i guess the authors were aware that it shouldn't be classified in the mentioned subphylum, but did it anyway, cause we have to study -some- deuteros that are not aspergillus haha
