- This video provides examples of members of the phylum Ascomycota (ascomycetes), describes their common characteristics, and presents the asexual and sexual life cycle of a multicellular (peziza) and unicellular (Saccharomyces cerevisiae ) ascomycete.

Your videos have helped me prepare for my biology of fungi and allied organisms exams so much! Great work and thanks again.
Great. I hope you aced the exams!
this is a great series you made - clear and concise and well informative. thank you!
I wish I found this earlier. Truly the best video on this topic!
It was awesome
I learned more than my book from your 10 minute video
Thank you very much
Please.....never stop making this AMAZING videos.....♥️♥️
not sure if anyone gives a shit but if you guys are bored like me atm you can stream all of the latest series on instaflixxer. I've been binge watching with my girlfriend lately =)
@Adam Jensen Definitely, I've been watching on instaflixxer for since november myself :D
This is the best video i have got for ascomycetes .....love it....👍👍😀
i m really appreciate your work. thanks a lot
Bravooo👏👏👏👏
I couldnt understand it at all
Yu just made it like a piece of cake❤🌸
Thank you for posting.
Thank you so much for the video! :)
Love you for this thank you soooooo much
tnxxx
thank u so much for such a great video 🙂
Thank You.
Thank you!
Your videos helped me a lot
Tysm sir 😊🙏
Thank you very much
Thank you this helps alot
thank you
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.
thank u sir , u litereally saved my life
Thank you soooooooooooooooooo much!
You're welcome!
Thnkz alot !
Thank you! This really helped
I am glad I can help.
Thankyou
thank you very much sir!!the explanation was amazing...I m very clear now..
You're welcome.

Great explnation! Would like more graphics net time pls... :3
Awesome upload
Thank you!
I've never heard of Aspergillus or Candida referred to as dimorphic? I thought only histo, coccidio, blasto and paracoccidio were dimorphic ?
Good explication, my english is not good but i can undestand you. One question, how do you make your videos, what programs are you using to draw?
Hi Diego, thank you for your comment. I used the Draw feature in PowerPoint (this video) and the Sketchable App for drawing. My images are PowerPoint slides and I record/edit using Camtasia. You can also use Screencast-O-matic fore recording/editing.
nice
I have a question what is the best example of the ascomytota? saccaharomyces cereviase, all of them, aspergillus, or penicillium?
The best example of an ascomycota fungi would be the Peziza because the ascus are fully formed and easy to recognize.

Where is the 8 haploid nucleus after mitotic division.?
3:19 bis 3:47 , that's the stuff :)
Hii may i ask why sexual reproduction were needed for these ascomycetes, since it seems like they can already survive with asexual reproduction
does aspergillus life cycle is three generations ? answer me plz nd thank you ^^
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
you are God
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.
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
Better if u used some graphics and more examples:)
Thank you, I will keep this in mind in my future videos.
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.
isn't penicillium a dueteriomycota
Still confused
isn't penicilium deuteromycotina?
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 hey, thanks a bunch, man! and no worries, the textbook is probably wrong, not an unusual thing where im from, haha
I'll be sure to.tell my professor about the discrepancy, and you've got a new subscriber
@@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
