|
Give an example of how fungi can be a threat |
Chytrid fungi are a major killer of amphibians |
|
|
What are the two forms of fungal growth? |
Yeast and hyphal growth |
|
|
How can dimorphic fungi grow? |
Both with yeast and hyphal growth |
|
|
What does fungal growth depend on? |
the delivery of vesicles to the growth region |
|
|
What supports motility along the cytoskeleton? |
Fungal motors |
|
|
Which motor moves moves towards the negative end? |
dyein |
|

|
|
What is the Spitzenkorper |
serves as a "vesicle supply center" |
|
|
Outline how the spitzenkorper acts as a vesicle supply center |
1. Transport along the cytoskeleton 2. Storage of vesicles in the spitzenkorper 3. Release and fusion with the plasma membrane |
|
|
The spitzenkorper contains several types of vesicles, true or false? |
True, the spitzenkorper contains secretory vesicles and endocytic recycling vesicles. |
|
|
What affects the rate of hyphal growth? |
The rate of vesicle release and motility of the spitzenkorper |
|
|
What is the problem with hyphal growth compared to yeast? |
The death of one cell in hyphal growth would result in the death of many more cells |
|
|
How to fungi over come the problem of cell death and multi-cellularity? |
Damaged hyphal cells are isolated by a plug known as a woronin body |
|
|
How do woronin bodies work? |
They plug the septa in filamentous ascomycetes |
|
|
Where are woronin bodies derived from? |
They are derived from peroxisomes and contains hexagonal protein Hex1 |
