So it Corexit is the core of the exit, then what is the outlaying matrix associated with it?
We can only guess.
Michigan hit with spill, not too far from Lake Michigan.
I have seen heavy spraying today, wonder if corexit is being used in the "white planes".
Once in the Great Lakes the cone has spread its matrix.
Just like the fungal network in us, the cone, goes back to That SPK.
Will someone turn the hose off?
Spitzenkorper fits as the n. crassa motor neuron.
They always follow schemes, and strange names of things.
Since the transport of virtually all organelles visible by computer-enhanced video microscopy in Neurospora is microtubule dependent (Steinberg and Schliwa, 1993), Nkin is a prime candidate for the motor that drives some or all of these movements. To address the question of kinesin function at the cellular level in more depth, we have generated a kinesin-deficient mutant by the technique of repeat-induced point mutations (RIP), an efficient method for gene disruption in Neurospora (Selker, 1990). Unexpectedly, neither the extent nor the character of organelle movements visible by computer-enhanced video microscopy were changed dramatically in Nkin-deficient cells. However, hyphal morphology and branching were severely altered, indicating that at least one step in cell morphogenesis requires kinesin. Detailed analysis of the mutant strongly suggests a severe defect in the long-range transport and correct delivery of small secretory vesicles required for normal hyphal growth.
the above studies were in n. crassa but seems the gene they were looking for could be in Ustilago .... seems it can form the spitzenkorper.
Indeed, it was shown that in U. maydis early endosomes cluster at sites of growth, where they support morphogenesis and polar growth, most likely via endosome-based membrane recycling.
In humans, such recycling processes to the plasma membrane involve small GTPases such as Rab4. A homologue of this protein is encoded in the genome of U. maydis but is absent from the yeast Saccharomyces cerevisiae, suggesting that Rab4-mediated recycling is important for filamentous growth.
Furthermore, human Rab4 regulates traffic of early endosomes along microtubules, and a similar microtubule-based transport is described for U. maydis. These observations suggest that Rab4-like GTPases might regulate endosome- and microtubule-based recycling during tip growth of filamentous fungi.
tash: Hi skizit, I have watched all your videos on youtube and cant thank you enough for all you have educated me on. I cry for you alot and a bit for me. I was wanting to send you photos of what is raining down everyday here in Australia in hope you can tell me
